Earth’s water doesn’t come from melting meteorites.

　　The white dotted line in the figure shows the boundary between the inner solar system and the outer solar system, and the asteroid belt is roughly located between Mars and Jupiter. Bubbles near the top of the image show that water molecules are attached to rock fragments, indicating the type of objects that may bring water to the earth.

　　Beijing Science and Technology Daily, March 16th (Reporter Zhang Jiaxin) Water accounts for 71% of the earth’s surface area, but no one knows how or when such a large amount of water arrived and existed on the earth. A new study published in the journal Nature on 15th brought scientists one step closer to answering this question. The researchers found that the water on the earth did not come from molten meteorites.

　　The research team of the University of Maryland analyzed the molten meteorites that have been floating in space since the formation of the solar system 4.5 billion years ago. They found that the water content of these meteorites was extremely low. In fact, they are one of the driest substances ever measured. These results make researchers rule out that they are the main source of water on the earth, which is of great significance for finding water and life on other planets.

　　The researchers analyzed seven molten meteorites, that is, spherulite-free meteorites, which split from at least five "planetesimals" and fell into the earth for billions of years. These planetesimals collided to form planets in the solar system. During the melting process, many of these micrometeoroids were heated by the decay of radioactive elements in the early solar system, causing them to split into layers with crust, mantle and core.

　　Since these meteorites have only recently landed on the earth, this experiment measured their volatiles for the first time. The researchers used electron probes to measure their magnesium, iron, calcium and silicon levels, and then used secondary ion mass spectrometry to measure their water content.

　　To reduce pollution, the researchers first baked their samples in a low-temperature vacuum oven to remove any surface water. The sample must be dried again before it can be analyzed in the secondary ion mass spectrometer.

　　After analyzing the samples of non-chondrite, the researchers found that water accounts for less than two parts per million in its mass. In contrast, the wettest meteorite — — Carbonaceous chondrites contain up to 20% water (by weight), which is 100,000 times that of the meteorite samples studied by the team. This means that no matter where these micro-planets originated in the solar system, and no matter how much water they had in the beginning, the heating and melting of micro-planets will lead to almost all water loss.

　　The researchers found that contrary to popular belief, not all extrasolar bodies are rich in water. This led them to conclude that water was probably transported to the earth through unmelted meteorites or chondrites.

Those seasonal fruits in autumn have their own merits! Did you eat right？

　　Editor’s note: Autumn is the season of bumper harvest of all kinds of fruits, and all kinds of seasonal fruits are also sold in the market. When autumn is dry, you should eat more fruits that are rich in water and have nourishing effects. There are also many eating customs in this period, such as "eating buds in summer and eating fruits in autumn". Although the fruit is good, the way to eat it is still very important. This edition selects three popular fruits in autumn to help you learn how to eat these nutritious autumn fruits healthily.

　　This fruit is in season, but it makes people "love and hate"! Interpretation of Several Questions about Persimmon

　　Autumn is full of fruitful harvest scenes. There is a folk saying that "the white dew hits walnuts, and first frost picks persimmons", and this is a good time to eat persimmons. Speaking of persimmons, the softened persimmons are thin, tender, sweet and delicious, so I really can’t help eating more. But many people stay away from it, because they heard that persimmons can’t be eaten, especially when they are eaten on an empty stomach. There is also a saying that people with anemia are not recommended to eat, which is more likely to be anemia; There are even rumors that the processed persimmon frost is a preservative. This article will take you to crack these "rumors" one by one and eat persimmons healthily and safely.

　　Q: Eating persimmon with stones on an empty stomach?

　　A: This statement is too absolute. There are other factors for stones.

　　Eating persimmons on an empty stomach is relatively more likely to produce stones, but the more critical factors for the formation of gastric stones are insufficient gastric motility, eating too much at a time or eating persimmons with high tannic acid for several days. If you eat astringent persimmon or ripe sweet persimmon on an empty stomach, you don’t have to worry too much about stones.

　　Persimmons are indeed related to gastrointestinal stones, mainly because persimmons contain more tannic acid, also called tannin, which is mainly concentrated in the peel. Its astringent taste is actually a way for plants to "protect themselves" from being eaten; Unfortunately, we humans have accepted this astringency, such as the unique flavor of wine and the heavy feeling of drinking tea, which is mainly brought by polyphenols such as tannic acid.

　　Suppose you eat a lot of tannic acid and enter the stomach, which polymerizes in the environment of gastric acid to form a gelatinous coagulum, and then forms a sticky mixture with protein and pectin, which slowly hardens into "stones", inducing stones and causing bloating and stomachache. If it is caused by persimmon, there is also a special name called "stomach persimmon stone"

　　According to the data, the appearance of "stomach persimmon stone" is related to gastrointestinal diseases (accompanied by weakened or disordered stomach function) or eating a lot of persimmons.

　　Of course, your stomach moves normally, and it is difficult to give tannic acid a chance to fully contact other food ingredients to "aggregate into a ball". Moreover, the persimmon varieties produced in agriculture are already low in tannic acid. We should know that the appearance of gastrolith is influenced by many factors, such as patients with a history of gastric surgery, diabetes, mental disorders, and acid-related diseases such as peptic ulcer and reflux esophagitis are also closely related.

　　Therefore, when diagnosing stones, we only care about persimmon intake, which is not comprehensive and needs comprehensive analysis.

　　Q: Pregnant women can’t eat persimmons?

　　A: It is purely a rumor.

　　As long as it is safe and hygienic, and it is not allergic to persimmons, it can be safely eaten. As long as the gastrointestinal function is normal, it is no problem to eat persimmons occasionally. Just follow the same precautions as before.

　　Q: People with anemia can’t eat persimmons?

　　A: Generally, it only appears in people who are vegetarian or eat a lot of persimmons.

　　As for the saying that "anemia can’t eat persimmons", I think tannic acid will affect the absorption of iron. Theoretically speaking, this phenomenon will only occur among vegetarians, and it is a long-term consumption of persimmons. Because only non-heme iron existing in plants will be affected by tannic acid, and the absorption rate of heme iron in animals will not be reduced because of tannic acid. Therefore, for most people, eating persimmons occasionally will not cause anemia.

　　For people with anemia, it is more important to know what causes anemia, rather than simply staying on the surface of "do you want to eat persimmons?" If it is a common iron deficiency anemia, eat more animal liver, animal blood and lean meat to increase iron intake, and supplement iron preparations when necessary.

　　Q: Is persimmon rich in nutrients?

　　A: Vitamin C is 10 times that of apples.

　　Persimmon is an out-and-out Chinese native fruit. Next, what is its nutritional value?

　　1. high vitamin c content

　　To say its biggest nutritional advantage, it is really not the golden color of persimmon that we thought would supplement carotene more, but vitamin C. A big crisp persimmon, about 200g each, can meet 60% of the daily demand for vitamin C (the recommended daily intake of vitamin C for healthy adults is 100mg), which is 10 times the vitamin C content of apples.

　　Compared with citrus family fruits with high vitamin C content, it is not inferior (persimmon 30 mg /100 g), such as orange 33 mg /100 g and tangerine 19 mg /100 g.

　　2. Carotene is good

　　The carotene content in persimmon is 120 micrograms per 100 grams, which is similar to that of orange, although it can’t catch up with mango. Like persimmon, the carotene content has more than tripled, which is equivalent to persimmon dehydration, and the nutrients in it have been concentrated.

　　β which is rich in carotene; -Carotene, which can be converted into vitamin A in the body, plays a very important role in eyes and skin.

　　3. It contains water-soluble dietary fiber such as pectin, which is helpful for relaxing bowels.

　　4. Moderate calories, equivalent to litchi and pomegranate.

　　However, persimmon can be as high as 255 kilocalories per 100 grams, which is higher than steamed bread (236 kilocalories /100 grams). Therefore, it should be noted that people who lose weight or control blood sugar should pay attention to eating less.

　　Q: Is the frost on persimmon a preservative?

　　A: Generally speaking, it is the frosting naturally formed during the production process.

　　Persimmons are often processed into persimmons because they are not resistant to storage, inconvenient to store and transport, and have short shelf life. To be processed into persimmon, you must peel it first. After peeling, the water inside the fruit is mixed with sugar and seeps to the surface. As the water evaporates during drying, the sugar of persimmon gradually crystallizes and accumulates on the surface, eventually separating out sugar such as glucose and fructose. In this way, persimmon with "white frost" was finally formed.

　　Therefore, the frost on persimmon is not a preservative, but a naturally formed frosting in the production process of persimmon, which is harmless to human body and can be safely eaten. Of course, we should be wary of some unscrupulous merchants who artificially sprinkle flour, starch and other substances on persimmon in order to improve the value of persimmon.

　　This is easy to distinguish. After "artificial whitening", the persimmon cake looks more evenly white. When you shake it gently with your hand, the white powder will fall off, which is fake. And its taste is not as sweet as the original persimmon.

　　Pay attention to the following three points and eat persimmons with confidence.

　　1. Don’t eat raw persimmons, and don’t eat persimmon skins. Choose fully ripe persimmons to eat without skins or choose sweet persimmons and dried persimmons. If the persimmon you bought is astringent, you can put it together with bananas and apples, put it in a plastic bag, or put it directly in a foam box, which can remove the astringency well.

　　2. The elderly and children with poor gastrointestinal function, who have gastroesophageal reflux and bloating, had better not eat on an empty stomach.

　　3. Don’t eat too many persimmons. According to statistics, eating two persimmons (400-500g) a day by healthy adults will not cause stomach stones, so children can just taste them. However, the situation varies from person to person, mainly depending on your gastrointestinal feeling. If you eat persimmon, your stomach will be uncomfortable, which means that your stomach and intestines are delicate, so don’t eat too reluctantly.

　　To sum up the knowledge points: eating persimmons on an empty stomach is easy to grow stones, and it cannot be generalized. The key factors for the formation of gastric stones are insufficient gastric motility and eating persimmons with high tannic acid for several days at a time. As long as the gastrointestinal function is normal, adults, pregnant women and people with anemia can eat persimmons; It is no problem for adults to eat one or two a day. Persimmons are concentrated in essence and can be eaten in half. The "white frost" you see is naturally formed icing, so you can eat it with confidence.

　　Autumn fresh jujube is on the market, why is it called "nutrition all-around champion"?

　　Who is the "nutrition all-around champion" in fruits? This honor, the most should be awarded to fresh jujube, people who want to maintain immunity should eat it quickly.

　　Fresh dates are rich in nutrients, especially vitamin C.

　　Fresh jujube is rich in vitamin C, B vitamins, dietary fiber, potassium and other minerals as well as a variety of organic acids, and its nutrition is very rich and comprehensive. In particular, the content of vitamin C is particularly high, up to 243 mg /100 g, and eating 40 g of fresh dates can meet the demand for vitamin C for one day. You may not have an intuitive feeling if you just say the value. When you supplement vitamin C, you may think of oranges, lemons, etc., and the vitamin C content in fresh dates is 7 times that of oranges, 10 times that of grapes, 11 times that of lemons and 20 times that of pomegranates. It is no wonder that fresh dates are called "the king of vitamin C" among common fruits.

　　The temperature difference between autumn and winter is large, and colds are easy to occur. For people with insufficient intake of vitamin C, proper vitamin C supplementation can maintain the body’s immunity. If vitamin C is lacking for a long time, it will make the important cells of the immune system — — The function of phagocytes is affected, and people are more likely to catch a cold, and are more prone to burnout and general fatigue.

　　For the average adult, the daily intake of vitamin C is 100mg/day, and the intake for preventing non-communicable chronic diseases is 200mg/day.

　　However, when eating fresh dates, be sure to choose fresh ones, because vitamin C is a water-soluble vitamin. In the process of water loss, vitamin C is also greatly lost, and the nutritional value of dried dates is not as good as that of fresh dates.

　　In addition to vitamin C, fresh dates also contain many nutrients, and the potassium content is 375 mg /100 g, which is higher than that of bananas, which is good for protecting blood vessels and preventing hypertension.

　　In addition, the content of carotene and zinc in fresh jujube is also high, which has the functions of antioxidation and skin protection.

　　Not only that, jujube also contains triterpenoids, vitamin P, adenosine cyclophosphate, etc. These substances have the function of assisting cancer prevention.

　　Fresh dates are sweet. Can diabetics eat them?

　　If the blood sugar control is stable, you can eat it, but don’t eat too much.

　　The sugar content of fresh dates is high, reaching 30.5%, which is higher than that of ordinary fruits. Diabetic patients can eat a few at a time, and it can be tasted. Excessive consumption will cause blood sugar fluctuations.

　　How much is better to eat fresh dates every day?

　　For the average adult, the simplest way to measure it is to grab a handful by hand every day, eat as much as you can, and try to eat between meals so as not to affect your appetite.

　　Eat jujube carefully and slowly, and chew the outer skin before eating it, because jujube skin is not easy to digest, especially for patients with gastrointestinal diseases. If you eat it too fast, it may increase gastrointestinal discomfort.

　　Grapefruit is full of treasures, and grapefruit skin also has three wonderful uses.

　　The fruit period of grapefruit is from September to December, and it is one of the favorite fruits in autumn. Grapefruit is crisp and tender, juicy and sweet, and rich in water, which can replenish water for the body and make people unable to stop eating it. Grapefruit is not only rich in nutrition, but also a good thing.

　　Grapefruit is rich in vitamins and minerals, and its glycemic index is not high, so it is suitable for diabetics.

　　Grapefruit is rich in vitamins and minerals, including vitamins such as vitamin B1, vitamin B2, vitamin C and carotene, and minerals such as calcium, phosphorus and potassium.

　　Every 100g of grapefruit edible part contains 84.8g of water, 12.2g of carbohydrate, 0.7g of protein, 0.6g of fat and 0.8g of crude fiber, and contains 57 kilocalories.

　　Grapefruit also contains a variety of micronutrients, including a variety of minerals, such as calcium 41 mg, phosphorus 43 mg, iron 0.9 mg; There are also many vitamins, such as carotene 0.12 mg, riboflavin 0.02 mg and niacin 0.5 mg.

　　As a natural antioxidant, vitamin C in grapefruit pulp can resist oxidation and lower blood sugar by scavenging free radicals in the body. The glycemic index (GI value) of grapefruit is 25, and the glycemic load (GL value) is 2. It can be seen that grapefruit is low in sugar content and suitable for diabetics.

　　Grapefruit peel is also a good thing to help reduce blood viscosity and reduce thrombosis.

　　Citrus grandis peel contains flavonoids such as naringin and rutin, which have antioxidant activity, can reduce blood viscosity and reduce the formation of thrombosis, and has a good preventive effect on cardiovascular and cerebrovascular diseases such as cerebral thrombosis and stroke.

　　Grapefruit has the function of lowering blood sugar because it contains many phytochemicals, but some of these phytochemicals exist in the inedible part of grapefruit — — Grapefruit peel. Pomelo peel has three major nutrients.

　　1. Natural pigments

　　Pigments in grapefruit peel include fat-soluble carotenoids and water-soluble yellow flavonoids.

　　Naringin, the main component of water-soluble pigment, is a kind of polyphenol existing in grapefruit peel, which has antioxidant and hypoglycemic effects.

　　2. Dietary fiber

　　Grapefruit peel is rich in dietary fiber, among which water-soluble dietary fiber has the effect of improving intestinal peristalsis and lowering blood sugar.

　　3. Pomelo peel pectin

　　Pomelo peel pectin is a kind of compound polysaccharide with straight chain and high molecular chain, which has the effect of reducing low density lipoprotein cholesterol, reducing the damage of arterial wall and lowering blood sugar.

　　Pomelo peel can be eaten or skillfully used in three recommended ways.

　　Grapefruit peel is green and slightly bitter, with a unique taste. Especially the pomelo peel of Shatian pomelo in Guangxi is thick, full, white and fragrant.

　　When eating grapefruit skin, you need to remove the yellowish skin and the floc tightly wrapped with pulp, leaving the soft part in the middle. Pomelo peel has three wonderful uses.

　　1. Soak in water to lower blood sugar

　　Diabetic patients should make full and comprehensive use of all parts of grapefruit if they want to lower their blood sugar through grapefruit. For example, the pomelo peel is soaked in water, and the pomelo peel is diced, and 15-20 pieces are put in water at 25-70℃ for 10 minutes at a time.

　　Step 2 cook

　　Pomelo peel is mixed with meat to make pomelo-flavored steamed pork, pomelo-flavored braised pork, pomelo-flavored pork pot, pomelo-flavored steamed pork ribs, etc. The pomelo flavor and meat flavor permeate each other, which has a unique flavor and can also play a role in dissolving greasy and helping digestion.

　　3. Natural deodorant

　　Pomelo peel has a porous structure, which can purify and adsorb formaldehyde in the air. Put the pomelo peel in the refrigerator, and the mixed odor of food will not only be removed, but only a faint grapefruit fragrance will be left.

　　Putting the dried pomelo peel into shoes can also deodorize and sterilize. The odor of sewers in kitchens and bathrooms can also be removed by washing and soaking with boiled pomelo peel water, which is simple and practical.

@ Everyone! From New Year’s Day next year, these new regulations are closely related to you!

　　Xinhuanet Beijing, December 27th (Reporter Lu Junyu) 2018 is the countdown, and in the coming year of 2019, a wave of heavy new regulations will be officially implemented.

　　Taxpayers will get greater tax cuts when the new tax law is implemented!

　　After several rounds of extensive consultation, on December 22nd, the State Council officially issued the Interim Measures for Special Additional Deduction of Individual Income Tax, which marked a key step for China’s individual tax reform to take comprehensive taxation, and taxpayers will receive greater tax reduction from next year.

　　The interim measures will be implemented on January 1, 2019 with the newly revised tax law. In the future, taxpayers can calculate the taxable income of individual tax, and besides the basic deduction of 5,000 yuan and special deductions such as "three insurances and one gold", they can also enjoy six special additional deductions such as children’s education, continuing education, serious illness medical care, housing loan interest or housing rent, and supporting the elderly.

　　E-commerce law governs online shopping chaos and treats online and offline fairly!

　　The E-commerce Law, which consists of seven chapters and 89 articles, provides detailed provisions on e-commerce operators, the conclusion and performance of e-commerce contracts, the settlement of e-commerce disputes, the promotion of e-commerce, and legal liabilities, and will come into force on January 1, 2019.

　　In order to protect consumers’ rights and respond to social hotspots, the E-commerce Law stipulates that for goods or services related to consumers’ lives and health, operators of e-commerce platforms fail to fulfill their obligation to review the qualifications of operators in the platform, or fail to fulfill their obligation to ensure safety for consumers, thus causing damage to consumers, they shall bear corresponding responsibilities according to law. If the operator of the e-commerce platform fails to take necessary measures against the behavior of the operator in the platform that infringes on the legitimate rights and interests of consumers, if the circumstances are serious, it shall be ordered to suspend business for rectification and be fined not less than 500,000 yuan but not more than 2 million yuan.

　　In recent years, mobile social media has become an important part of people’s daily life, and Wechat business has sprung up and developed rapidly. In view of this new situation, the e-commerce law has expanded the definition of e-commerce operators, and included Wechat business and live broadcast platforms in the supervision. And refine the joint liability of the e-commerce platform and the operators in the platform, and increase the review obligation of the e-commerce platform. Standardize e-commerce enterprises and platforms, and put an end to the phenomenon of "big data killing", "store bullying" and "barbaric growth".

　　The organic law of the "two houses" was overhauled for the first time in nearly 40 years, and the achievements of judicial reform were comprehensively confirmed and consolidated.

　　The Organic Law of the People’s Court and the Organic Law of the People’s Procuratorate came into effect on January 1, 2019. This is the first major overhaul of the Organic Law of the "two houses" in the past 40 years, which comprehensively confirmed and consolidated the achievements of the judicial system reform in recent years.

　　This revision has improved the organization and authority of courts and procuratorates. For example, according to the Law on the Organization of Courts, the Supreme People’s Court can set up circuit courts, intellectual property courts and financial courts, which are all important manifestations of judicial reform in court organization.

　　In terms of improving the effectiveness of legal supervision, the Organic Law of the People’s Procuratorate stipulates that the People’s Procuratorate may, according to the needs of procuratorial work, set up procuratorial offices in prisons, detention centers and other places, exercise part of the functions and powers of the people’s procuratorate that dispatched it, or conduct patrol inspections in the above places.

　　New version of birth certificate launched

　　According to the announcement of the National Health and Wellness Committee in official website, the medical certificate of birth will be revised soon. Since January 1, 2019, the medical certificate of birth (the sixth edition) issued by the National Health and Wellness Committee will be activated.

　　Social insurance premiums shall be uniformly collected by the tax authorities.

　　The "Reform Plan for the Collection and Management System of National Taxation and Local Taxation" clarifies that from January 1, 2019, various social insurance premiums such as basic old-age insurance premiums, basic medical insurance premiums, unemployment insurance premiums, work injury insurance premiums and maternity insurance premiums will be uniformly collected by the tax authorities.

　　This reform will have a series of important effects. Previously, five social insurances were collected by the social security handling department and the tax department in different regions, which was in a situation of "separate collection". After the introduction of this plan, they will be collected by the tax department in a unified way, thus improving the collection efforts and solving the once-existing problem of false fee base. Specific to the actual operation, the release of the "Reform Plan" means that the previous situation that some enterprises did not provide social security for their employees or did not provide full social security for their employees is expected to be changed, which is conducive to implementing the penalty for unpaid social security fees in Article 63 of the Social Insurance Law and standardizing the social security payment behavior of market participants.

　　China adjusts some import and export tariffs

　　From January 1, 2019, China will adjust the import and export tariffs of some commodities.

　　In order to actively expand imports, cut down the institutional costs of import links and help supply-side structural reform, China will impose provisional import tax rates on more than 700 commodities, including adding zero tariffs on miscellaneous meals and some raw materials for pharmaceutical production, appropriately reducing the provisional import tax rates on cotton sliding duties and some furs, canceling the provisional import tax rates on four solid wastes such as manganese slag, canceling the provisional import tax rates on thionyl chloride and lithium-ion batteries for new energy vehicles, and resuming the MFN tariff rate. We will continue to impose a lower provisional import tax rate on advanced equipment such as aero-engines and welding robots in automobile production lines, natural forage and natural uranium, which are urgently needed for domestic development.

　　In order to meet the needs of the reform of the export management system and promote the structural adjustment, quality improvement and efficiency improvement of the energy resources industry, since January 1, 2019, 94 commodities such as fertilizer, apatite, iron ore, slag, coal tar and wood pulp will no longer be subject to export tariffs.

　　China adjusts cross-border e-commerce retail import policy

　　From January 1, 2019, China will adjust the tax policy for cross-border e-commerce retail imports, raise the upper limit of commodity quotas enjoying preferential tax policies, and expand the scope of the list.

　　The adjustment of tax policy will increase the annual transaction limit from 20,000 yuan per person per year to 26,000 yuan, and the camera will be raised with the increase of residents’ income in the future. Raise the limit of a single transaction to 5,000 yuan, and make it clear that the duty-paid price exceeds the limit of a single transaction but is lower than the annual transaction limit, and only one commodity can be imported from the cross-border e-commerce retail channel, and the customs duties, import value-added tax and consumption tax are fully levied according to the goods tax rate, and the transaction amount is included in the total annual transaction amount. It is clear that cross-border e-commerce retail imported goods that have been purchased shall not enter the domestic market for re-sale.

　　In 2019, the national unified medical insurance system for urban and rural residents was fully implemented.

　　It is understood that the National Medical Insurance Bureau recently jointly issued the Notice on Doing a Good Job in Basic Medical Insurance for Urban and Rural Residents in 2018 with the Ministry of Finance, the Ministry of Human Resources and Social Security and the National Health and Wellness Committee. The notice is clear and promotes the establishment of a unified medical insurance system for urban and rural residents. All localities should pay close attention to promoting the integration of the basic medical insurance system for urban and rural residents. Areas that have not introduced the integration plan and have not yet started operation should pay close attention to the introduction of the plan and start implementation as soon as possible.

　　According to the notice, in 2018, the financial subsidies for medical insurance for urban and rural residents and individual payment standards will increase simultaneously. 40 yuan will be added to the per capita subsidy standard of finance at all levels on the basis of 2017, reaching no less than 490 yuan per person per year. In 2018, 40 yuan will be added to the per capita personal payment standard of medical insurance for urban and rural residents, reaching 220 yuan per person per year.

　　The implementation of the Law on the Prevention and Control of Soil Pollution has made people feel at ease in eating and living.

　　The Law on Prevention and Control of Soil Pollution in People’s Republic of China (PRC) will be implemented on January 1, 2019, which is the first time that China has formulated a special law to regulate the prevention and control of soil pollution.

　　The law on the prevention and control of soil pollution consists of seven chapters and ninety-nine articles. The law clarifies that the prevention and control of soil pollution should adhere to the principles of prevention first, protection first, classified management, risk control, pollution responsibility and public participation.

　　According to the law, the state implements the list system of soil pollution risk control and remediation for construction land. The law stipulates the conditions, procedures, risk control and restoration measures to be taken for entering and leaving the land under the list management. If required by law, the land included in the list of soil pollution risk control and restoration of construction land shall not be used as residential, public management and public service land.

　　In addition, the law has formulated detailed punishment measures for illegal acts.

　　Implementation of the Regulations on the Administration of Administrative Divisions

On the basis of summarizing the implementation experience of the State Council’s Regulations on the Administration of Administrative Divisions for more than 30 years, the State Council formulated the Regulations. The promulgation and implementation of the "Regulations" is of great significance to the implementation of the major decision-making arrangements of the CPC Central Committee and the State Council on optimizing the setting of administrative divisions and strengthening the management of administrative divisions.

　　The official release of six national standards for electronic licenses has helped to realize the "one network management" nationwide.

　　The State Administration of Market Supervision, the National Standardization Administration Committee and the National Inter-Ministerial Joint Conference Office of Electronic Document Management (National Cryptography Administration) have recently officially released six national standards, namely, the overall technical framework of electronic license, the information specification of electronic license catalogue, the metadata specification of electronic license, the identification specification of electronic license, the technical requirements of electronic license documents and the interface specification of electronic license sharing service.

　　With the deepening of the reform of "Internet+Government Services", electronic license, as a professional and voucher electronic document with legal and administrative effects, has increasingly become the main electronic certificate for market participants and citizens’ activities, and is an important basic data to support the operation of government services. The formulation of national standards for issuing electronic licenses will provide standard support for the construction of national electronic license database and basic platform, the mutual recognition and sharing of electronic licenses across levels, departments and regions, and the integration and sharing of government information resources with licenses.

　　According to reports, the series of standards for electronic licenses issued this time stipulate the overall technical framework, unified license classification rules and basic information of electronic licenses, which will help promote the realization of "one network to run" nationwide, make the sharing of government information resources and services smoother, and make people feel that it is more convenient to do things. This series of standards will be implemented on January 1, 2019.

International exchange and cooperation is an important way to cultivate high-quality talents and plays a vital role in promoting talent cultivation.

Table tennis prediction： table tennis is heading for a happy ending.

　　Xinhuanet Beijing August 22nd Olympic Special (Reporter Zhang Han, Wu Zhi) The table tennis match of the Beijing Olympic Games entered the last competition day on the 23rd. After the men’s and women’s teams all won two gold medals, and the women’s singles final became a "civil war", the three men’s singles tigers will advance towards the highest podium again.

　　I have to admit that China Table Tennis Team has sent the strongest team in the history for this Olympic Games. Wang Hao, Ma Lin and Wang Liqin, three contestants of China Men’s Table Tennis, are currently ranked first, second and fourth in the world, respectively, ranking third in the tournament. Because of this, they are in an excellent position in the singles draw, and before entering the quarter-finals, all the strong enemies have been swept away.

　　In the quarter-finals on the 22nd, Wang Hao beat former China straight player Gao Lize 4-1, Ma Lin beat South Korean Sang Eun Oh 4-0, and Wang Liqin beat Croatian Tan Ruiwu in straight sets, which was no suspense. Persson, a 42-year-old Swedish veteran against Wang Hao, will become the only non-face of china in the men’s singles semi-final on the morning of 23rd.

　　China men’s table tennis has not lost a game since the Olympic Games, and the gold medal won by the men’s team has given them more confidence. As long as Wang Hao plays his level normally, it is not difficult for China to lock the gold medal in men’s singles ahead of time by beating persson with his skill of straight strokes and horizontal strokes.

　　In fact, as early as the 21 ST men’s singles eighth final, many Eurasian masters have been eliminated. China Hongkong’s Gao Lize defeated defending champion Ryu Seung-min in the top 32 match that morning, and then defeated German teenager Ochalov 4-1 in the eighth final that night, and got the chance to play against Wang Hao in the quarter-finals.

　　Persson, who played one more round than the previous 16th seed, eliminated samsonov, the number one table tennis player in Europe, Sang Eun Oh, the 12th seed, defeated Bohr, the 5th seed of Germany, Tan Ruiwu defeated Li Jing, the former world champion, Austrian Shi Lage and former World Cup champion, and glinka, Greece, lost to Wang Liqin and Ma Lin respectively.

Ma Lin beat South Korean player Sang Eun Oh China 4-0 and all the men’s table tennis players advanced to the semi-finals.

Tenghage is well aware of his Manchester United squad, however, once one of these players is absent, the standard will plummet. In particular, midfield starters bruno fernandez, casemiro and Eriksson, who started the team together, remained unbeaten, but only seven times this year, Manchester United won 6 wins and 1 draw.

However, Tenghage did not dare to rotate. Manchester United lacked the thickness of the squad and could not have two reliable players in every position. Especially key players like Rachford and B Fei can’t rotate, so their chances of fatigue, injury or suspension are naturally higher. Rachford recently missed three games due to groin injury. His goal count (28 goals) is nearly three times that of any teammate, and only B Fei scored in double figures.

In Seville’s Europa League, Manchester United was out of the game, Vallanet, lisandro Martí nez and Garnacho were injured and missed, B fee was suspended, Rachford and Luke Shaw served as substitutes, and the team fell behind in all aspects.

Tenghage said: "We have to admit that we have problems and don’t have enough manpower, especially in the front line. Sometimes you have to make some decisions to win the next game. For example, using the same starter, which helps to get into the rhythm of the game. But after playing too many games and the load is getting higher and higher, you need to take turns. 」

If the conditions are right, Manchester United hope to carry out a major cleaning this summer and introduce high-level new aid. However, this requires funds. The Glazer family has not sold the club yet, and whether the Qatari financier can become the new owner is in doubt. The reconstruction of Tenghage needs a lot of money, reaching the astronomical level.

Who was most responsible for Manchester United’s first goal against Seville? Degea and Maguire fans have their own opinions. From the normal analysis, the responsibility of the English centre-back is even greater, because Degea’s passing has full space for him to handle the ball well.

A video of lisandro Martinez answering Degea’s similar pass shows everything. Under almost identical circumstances, the Argentine iron guard controlled the ball and successfully passed it to his teammates. And if a team wants to pass and control the organization in the backcourt and want to meet the players without any opponents, it is impossible to achieve it.

Of course, based on Degea’s knowledge of Maguire, he should probably play it safe. He would rather kick the ball out of the sideline than pass it to the 80 million-pound iron guard, as he did with Norwich. Of course, if the Spanish goalkeeper does this, then Tenghage and the fans will definitely point at him. "A goalkeeper who can’t pass the ball. "You can imagine people would say this about Degea," Maguire’s position is so empty that he dare not pass it on? 」

To be sure, Degea and Maguire are out of character. Maguire’s turning speed is slow, and his chasing ability is poor, so he needs the goalkeeper to dare to attack and help him out. Unfortunately, this happens to be Degea’s shortcoming. Therefore, since their cooperation, problems have emerged one after another, and it was not until Lima and Vallanet took the place of the big head that things changed.

Ideally, if Manchester United want to really rise, they need to replace both and introduce a new goalkeeper and a substitute central defender. There are quite a few similar rumors, and the leading role candidates mainly include four: brentford’s Spanish goalkeeper David Laya, Porto’s Portuguese No.1 diogo Costa, Napoli’s Korean international Min Kim Zai and Ajax’s Dutch central defender Timber.

Because of financial constraints, if only one of these two positions can be reinforced, then Maguire is the one who should be cleaned. He has no worries about finding a next home, and the price of the replacement is cheaper. Tenghage can further raise funds by selling central defenders such as Eric Baye.

In defence, Manchester United also need a main right-back. Frimpong, the Dutch international of Leverkusen, is a favorite candidate of Tenghage, and his price is 44 million pounds. By selling one of the existing right-backs, Diogu Dallo or Wanbisaka, plus two other redundant full-backs, Brandon Williams and Tres, about 30 million pounds can be raised.

The above positions belong to the lower-ranking areas in Tenghage’s signing plan. The two positions he must buy in the summer transfer window are midfield and center.

The rumored candidates are already fixed, including Frankie De Jong of Barcelona, Jude Bellingham of Dortmund, harry kane of Tottenham and Osman of Naples. Among them, Deong and Kane are the first choice of Tenghage.

Manchester United’s main lineup after the update: Raya/Frimpong, Vallanet (Min Kim), Lima, Luke Shaw/bruno fernandez, casemiro, De Jong (Eriksson)/Anthony, Kane and Rachford.

Manchester United signing candidate list:

Goalkeeper: Raya (40 million pounds) or Costa (70 million pounds);

Central defender: Min Kim (40 million pounds) or Timber (50 million pounds);

Right back: Frimpong (44 million pounds);

Midfielder: De Jong (80 million), Bellingham (130 million), mcallister (70 million) or caycedo (100 million);

Forward: Kane (100 million pounds) or Osman (130 million pounds);

Total cost: 300 million to 400 million pounds.

These five positions in one step, at the same time, is undoubtedly the best choice. However, due to UEFA’s new financial fair competition rules, it is difficult for Manchester United to spend more than 300 million pounds in a transfer window. Therefore, Tenghage had to make a trade-off. In the eyes of British media, his ranking may be: center, midfielder, right back, central defender and goalkeeper.
