　　With the outbreak of the COVID-19 epidemic, the people of the whole country are united as one, and Qi Xin is united in fighting the epidemic. In this battle without smoke, in addition to the medical staff and related workers who went to the front line, ordinary people consciously isolated themselves at home, went out less and didn’t get together, trying to control the epidemic in a short time. Of course, in the days of anti-virus at home, from motionless to motionless, from motionless to motionless, people always feel that the outside world is really wonderful. And the children want to go out and have a close contact with nature.

　　For this epidemic, I believe everyone has already understood that it is generally susceptible to the crowd, and the elderly and people with basic diseases are seriously ill after infection. For teenagers and children, from their physiological and anatomical characteristics and autoimmune function, respiratory tract infections are more likely to occur, and the younger they are, the less likely they are to be found. Once they get sick, they progress faster. Recently, the number of cases of children infected with novel coronavirus has gradually increased, and the smallest infected person is a baby less than 3 months old. Therefore, daily protection and observation at home are the key points to prevent infection among teenagers and children. However, it is children’s nature to move and play. In the face of this epidemic, exercise is also an effective means to improve immunity. On the contrary, sedentary will lead to decreased immune function and increased risk of infection. Although it is not suitable to go out, parents take their children to do some interesting little exercises at home, which can not only enhance immunity and prevent infection, but also release their children’s nature and get happiness in sports.

　　Small body arithmetic, fitness and brain health.

　　Use your body to express simple arithmetic with your child.

　

　

　　Arithmetic 1: 1+1=2

　　Action essentials: raise an arm to represent "1", the big arm is parallel to the ground, and the small arm is perpendicular to the big arm; The horizontal lifting of both hands forms a "+"with the trunk; Raise your hands horizontally in front of you for "="; Raising both hands at the same time means "2".

　　Arithmetic 2: 2+2=4

　　Action essentials: The number "4" can be represented by bending down, straightening your arms and touching the ground as far as possible. Your hands and feet form a "4", so be careful not to bend your knees during pressing. Parents can also let their children use their brains to find other body language that means "4".

　　Arithmetic 3: 4+4=8

　　Action essentials: The number "8" is represented by putting your hands on your hips and twisting your waist clockwise or counterclockwise, just like the "8" around a twist. Parents can also find more "8" expressions with children.

　　Parents can take their children to continue to explore more physical arithmetic. After studying at their desks and watching TV, let them get up and do a set of such physical arithmetic together to avoid becoming couch potatoes. You can also disrupt the order and test each other with your children to see who can react faster and do more standard, and keep fit and strengthen your brain at the same time.

　　Stop at the red light and go at the green light, and don’t forget to learn the rules for fitness.

　　Preparation stage: everyone stays still and waits for the password.

　　Red light: when you hear the red light command, stop moving immediately, keep your posture immediately, and wait for the next command.

　　Green light: start jumping, jump with your hands and feet open, keep your arms straight, and clap your hands above your head; Jump again, feet together, arms straight down from both sides, hands touching both sides of thighs, and so on.

　　Play traffic light games with children at home, and the rules are issued by giving a password that makes people shout red or green lights. When the red light is red, everyone stays still, and when the green light is green, everyone immediately starts jumping together. Participants in the game should give the fastest response according to the password, and the slowest response or the opposite response to the password is a challenge failure.

　　People can increase the difficulty and interest of the game by repeating instructions and adjusting the interval between instructions. The jumping time of the green light should not exceed one minute, and it can be marked by the child’s accelerated breathing and slight sweating. The traffic light game can help children learn rules in the game and improve their reaction ability. At the same time, the opening and closing jump in the green light can also improve their cardiopulmonary endurance.

　　Bear crawling, crab crawling, imitating animals is more fun.

　　Although it is impossible to go out at home, parents can take their children at home to imitate the small animals in nature and crawl freely at home.

　　Bear crawling: imitate the bear crawling forward, backward, left and right with his hands and feet. During crawling, try not to touch the ground with his knees and keep his trunk parallel to the ground as much as possible. Parents can also deliberately raise the trunk to let the children get out from below to improve the fun.

　　Crab crawling: imitating crab crawling, parents lead children to support their trunk with their hands and feet in a supine posture, lift their hips off the ground, crawl left and right with their hands and feet, and touch the ground with their hips is a challenge failure. In the process of crawling, children’s coordination can be improved and their core control ability can be exercised.

　　The above small sports and games are suitable for home, and at the same time, children’s immunity, sensitivity, coordination, cardiopulmonary endurance and other physical qualities and functions can be improved through exercise. The recommended amount of physical activity for teenagers and children is not less than 60 minutes of moderate and high-intensity physical activity every day. Parents can take their children to practice for many times, and each time they do a small exercise of 20-30 minutes. The intensity of exercise is appropriate for children to sweat slightly, breathe faster but still have a short conversation. Although children are longing for the outside world, playing some small fitness games with parent-child interaction at home in special periods can also exercise, enlighten wisdom, enhance parent-child feelings and have a pleasant and unforgettable holiday.

　　In the hot summer, delicious and juicy fruit has become a must-have for cooling off the heat. However, when we are feasting, have you ever wondered whether we are eating fruit pulp? Come and get to know them again with the Municipal Bureau of Greening and City Appearance.

　　People used to think that the juicy part of fruits is their pulp. In fact, there is no concept of "pulp" in botany. Because when the fruit is still a flower, the seed is not a seed, but an ovule. These little guys with high hopes are born in the ovary of the pistil and protected by the ovary wall. With the vigorous growth of ovules, the ovary that protects them has also developed into the most dazzling part of the plant-the fruit. This kind of fruit developed from ovary is called true fruit, and the fruits of most plants belong to true fruit. The structure of true fruit is simple, with pericarp outside (developed from ovary wall) and seeds inside (developed from ovule). Pericarp can be divided into exocarp, mesocarp and endocarp, and the three layers of pericarp are very different in different fruits. In addition to the ovary, there are other parts, such as flower receptacle, calyx, inflorescence axis and so on, which are also involved in the formation of fruits called false fruits.

　　peach

　　Take a peach as an example. The thin skin that is peeled off is its exocarp. The discarded peach stones (and the peach kernels inside) are endocarps and seeds. Therefore, the juicy peach meat that everyone eats is actually a fleshy mesocarp. This type of fruit also includes apricots, plums, plums, cherries and so on, which belong to Rosaceae with peaches.

　　tangerine

　　Not all fruits are so "serious" as peaches. For example, the best part of orange fruits is actually in the endocarp. What is it?

　　It is because the multicellular epidermis of the endocarp is specialized into juicy "meat strips". Simply put, the part we eat is "orange hair", and the orange peel we peel off is the part that closely combines the exocarp and mesocarp, while the "orange network" that some obsessive-compulsive babies dislike is the product of the specialization of the inner layer of mesocarp.

　　strawberry

　　A little bit of strawberry skin can grow strawberries, but this little black dot is not the seeds of strawberries. Small dots distributed on the surface of strawberry are the real fruits. These small achenes get together. In botany, we call it "aggregate fruit". The red part we eat is its swollen fleshy receptacle.

　　watermelon

　　The receptacle of watermelon is also involved in the development of fruit, but it is only in the "watermelon skin" part. If you cut the watermelon in half, you will find three heart-shaped dividing lines inside. The part outside the dividing line is the middle and inner layers of pericarp after pulp expansion. Within the dividing line, it is the soul of watermelon-that is, the pulp we eat is actually its placenta (where the ovule is born).

　　lychee

　　Peel off the uneven shell of litchi, and there is a white film inside, which is its endocarp. The plump and crystal-clear part that we usually eat is the aril of litchi.

　　The aril of litchi is developed from the suspensor (the part where the base of ovule connects with the placenta) and its placenta. Aril is a special kind of seed coat appendage, which is a structure developed by seed plants to adapt to the environment and has important biological research value. Like litchi, the edible parts of many tropical fruits such as longan and durian are arils.

　　Say so much.

　　It turns out that all the fruits we eat are not necessarily pulp.

　　So, everyone is going to eat the skin and fur of fruit.

　　Placenta or aril?

In winter, if you want to experience the joy of outdoor skiing, you don’t have to go to a distant place, but you can do it in Wuhan.

On January 20th, the Four Seasons Ski Resort in Runqu Valley Scenic Area in Junshan New City of Wuhan Economic Development Zone held a media open day. Dozens of provincial and municipal media representatives took to the snow trail to experience the speed and passion on the snow with the citizens.

Relying on Zhushan Lake, this ski resort is the first outdoor ski resort in Wuhan, only 30 minutes’ drive from Hankou. At the same time, it is also a happy world integrating skiing, snow skiing, water sports, camping and parent-child paradise.

According to reports, the length of the snow trail of the Four Seasons Ski Resort in Zhongrun Qugu Scenic Area is more than 200 meters, and the slope is about 15 degrees, reaching the scale of the intermediate sports track. The real snow on the snow trails is made on site by professional snow makers-the snow makers constantly spray white snowflakes from the pipes, and after the snow accumulates to a certain volume, it is compacted and smoothed by professional snow rollers to form a series of snow trails.

This year, the ski resort has expanded to nearly 1,000 square meters, and the magic carpet has increased by hundreds of meters, reaching the highest point of the snowy road. There is a tourist reception center of nearly 1,000 square meters in the ski resort, and the ski hall is equipped with thousands of brand-new ski equipment, attracting skiers from Wuhan.

"I didn’t expect to achieve skiing freedom at home!" Mr. Zhu, a citizen of Wuhan, said with excitement after taking his children to experience it. Unlike the indoor ski resort, he jumped from the 200-meter-long snowy road and glided down, which felt like flying in the air. "It’s as refreshing as flying in the air!"

In addition to ski resorts, Zhongrun Qugu Scenic Area, which covers a total area of more than 600 mu, also has outdoor parent-child amusement parks, little red elephant parent-child amusement parks built in the Woods, unpowered facilities, slides, jungle adventures and other amusement facilities; It is also a paradise for camping enthusiasts, traveling through the forest path with three or two friends or family members and feeling the sunshine and breeze outdoors. When you are tired of shopping, let’s set up tents together, barbecue, cook tea and chat under the stars, stay away from the hustle and bustle of the city, let go of the fatigue of work and be a completely relaxed self.

It is understood that Zhongrun Fun Valley Scenic Area is closely preparing for the Xuexiang activity project of Wuhan Economic Development Fun Valley, and strives to open it to the public from the first day to the fifteenth day of the first month.

Liverpool, the Premier League giants, did not perform well at the beginning of this season, which once made fans fail to see their hope of winning the Champions League next season. Fortunately, with the deepening of the season, Liverpool gradually came out of the trough. In the last round, the Double Red Club wiped out the old enemy Manchester United 7-0 at home, climbing to the fifth place in the standings, only three points behind Tottenham in one game less, which can be said to have grasped the initiative in the battle for World War IV! This week, the 27th round of the Premier League started in full swing, and Liverpool went to the away game to challenge Bournemouth. During the first leg of the season, Liverpool beat their opponents 9-0 at home, which is why fans thought they could easily kill each other.After the game started, Liverpool took advantage of the scene, but it was too late to score. On the contrary, Bournemouth took advantage of a few offensive opportunities and Billing scored the only goal in the game. In the end, Bournemouth avenged Liverpool 1-0!

Although the opponent’s strength is not very strong, klopp didn’t let his guard down. After all, the Premier League has always been unpopular. In this game, Uncle Zha followed the 4-3-3 system, allison continued to play for the team, and Arnold, konate, Fan Dike and Robertson formed a four-back, Elliot, Fabinho and bajcetic sat in the midfield, while the front trident was Salah and Gack who scored twice in the last game.

After the referee blew the whistle at the start of the game, Liverpool kept the ball firmly under their feet and stormed towards Bournemouth’s goal. In the 5th minute, Liverpool got a right corner kick, Arnold drove the ball to the back, Fan Dike jumped high and headed the ball to the far corner. Bournemouth’s goalkeeper had given up, but it was cleared by the defender’s goal line.

However, two minutes later, Arnold made a fatal mistake in the midfield, which made Bournemouth hit back conveniently. Ouattara got a single-handed goal. Unfortunately, after passing allison, Liverpool missed the goal at a small angle, and scored in the 13th minute. Gakpo scored the goal after receiving the ball from his teammate in the restricted area. The referee immediately signaled offside and cancelled the goal.

In the 23rd minute, Bournemouth hit back again.Ouattara succeeded in offside on the right. After receiving a long pass from his teammates, he directly killed Liverpool’s restricted area. Then he made a cross from the bottom and found Billing who followed in the middle. The latter easily pushed and scored meritorious deeds, helping Bournemouth to take a 1-0 lead.

In the second half, klopp changed into jota, and wanted to continue to strengthen the team’s attack. In the 49th minute, Jota finished a threatening shot at the front of the restricted area, but the Bournemouth goalkeeper was in a very brave state, and he managed to save the ball to keep the goal clean.

In the 67th minute, Milner sent a cross from the right, and jota headed the goal. The ball hit the open arm of the Bournemouth defender and went out of the bottom line. After returning to VAR, the referee gave Liverpool a penalty.Unfortunately, Salah’s penalty kick was wide of the mark, and Bournemouth was lucky to hold the lead by one goal.

In the next 30 minutes, the backward Liverpool put a lot of pressure on Bournemouth’s goal, but it bombed indiscriminately and failed to knock on the opponent’s goal. In the end, it could only accept the result of losing 0-1. The Double Red Club bloodied Manchester United with 7 goals, and then lost to the relegation team 0-1. This is also the reason why many fans ridiculed after the game. Liverpool did everything to humiliate the old enemy Manchester United!

At present, the Chengdu World Table Tennis Championships, which has attracted the attention of table tennis fans all over the world, has decided the final king. China Guoping, the king of the world table tennis world, won the championship of men’s team and women’s team without accident. This result is also the embodiment of Guoping’s top strength. However, although the champion belongs to Guoping, for some defeated players of Guoping, they have to find something else to show their unconvinced. No, Japanese table tennis, which has been suppressed by national table tennis, came back to China, and the Japanese media released a list of male table tennis players in the World Table Tennis Championships. Funny thing is, in this list, Malone, who won all seven games in the World Table Tennis Championships, was directly ranked fourth. At present, Fan Zhendong, which ranks first in the world, is directly ignored by the Japanese media, and can’t even enter the top five. As for the number one player, I believe you should have guessed it.

Chengdu World Table Tennis Championships, as a major competition this season, almost all the top table tennis players in the world came to Chengdu to participate in this table tennis feast. As the host country and the top table tennis team in the world, Guoping is naturally the favorite of the champion. However, neither the men’s team nor the women’s team let the fans down. In their own home court, Guoping won two championships in a sweeping way. Of course, compared with the women’s team, there are still some waves in the men’s team’s championship.

In the semi-final with the Japanese men’s team, the China men’s team encountered the biggest challenge since the start of the game. Japan’s first brother, Chinese-American Zhang Benzhi, is in very good shape in this World Table Tennis Championships, especially in this Sino-Japanese table tennis semi-final. In order to test Wang Chuqin, the national table tennis coaching staff arranged for Wang Chuqin to serve as the second single against Zhang Benzhihe. Wang Chuqin, like Zhang Benzhihe, is a post-00 player, which can also be regarded as a confrontation between new forces in the future table tennis world. But what I didn’t expect was that Wang Chuqin lost completely in this post-00 showdown.

If Wang Chuqin’s loss is understandable, then the number one player in the world, the key player of China team, the loss of a single Fan Zhendong made the fans feel nervous. In the face of Zhang Benzhihe, Fan Zhendong lost his former swagger and was defeated by Zhang Benzhihe. In the end, although Guoping still relied on its overall strength, it eliminated the Japanese team and advanced to the final. However, this five-game game still made many fans sigh: Fortunately, there is only one Japanese team, Zhang Benzhi and He.

It was Zhang Benzhihe’s performance that completely stunned the Japanese media after the game. After the World Table Tennis Championships, the Japanese media "Tokyo Satellite TV" produced a ranking of men’s table tennis strength in the World Table Tennis Championships. To tell you the truth, this ranking is a bit interesting. He is convinced of the players’ victory in the World Table Tennis Championships as a basis for ranking. In other words, whoever wins more games will be in the top position. That’s right, there is such a funny situation. No one of the main players in table tennis can enter the top three. After all, the seven wins of seven battles, which are as strong as Malone’s, can only be ranked fourth because of too few wins. Fan Zhendong, the number one in the world, can’t even get into the top five in this ranking.

Not surprisingly, in this ranking, the number one player in Japan’s team is naturally Zhang Benzhi and He. He ranked first with 11 wins and 1 loss, and was called the strongest men’s singles player in this World Table Tennis Championships. The second place is Huang Zhen Ting, a Hong Kong player from China who scored 8 wins and 3 losses. The third place is Qiu Dang from Germany, whose record is 8 wins and 4 losses.

To be honest, this ranking is totally unreasonable. After all, because of the strength of national table tennis, all the five main players have strong strength, basically taking turns to play. In this way, Malone’s chances of playing will naturally be less. However, Malone only played seven games, but he won all. Just because he played a few games less than Zhang Benzhi, is he weaker than Zhang Benzhi in strength? It can only be said that this is just the self-satisfaction of the Japanese media, which specially found an angle that is beneficial to Japanese players to make such a ranking. However, it is difficult for them to think of such an angle.

In the era of a large change in the past 100 years, artificial intelligence serves as the core technology of the new round of technology revolution and the industry revolution. For the importance of global development, artificial intelligence technology determines that the international leadership of the big country is almost one inevitable. However, the uncertainty of artificial intelligence development has also exacerbated the difficulty of technical risk management, bringing new challenges for global governance.

First, the high productivity of artificial intelligence also means high fortification.Wealth accumulation and speed and international strength contrast will have a more obvious partial wild, that is, the rich country is rich, the strong country is more strong, and the poor country is the stronger, the weak country weakens, resulting in more wealth unevenness and unfair Incorrectization, more conflict with conflict and conflict and terrorism, this is a greater uncertainty and governance of global governance.

Second, artificially intelligent high execution also means high destructive power.If the new weapons and network viruses, there is an endless body condition that has the human body conditions and the unknown tired action, which will bring benefits to the implementation tasks of various countries, but may also be used by some forces, thus giving international Society has brought serious safety hazards, and may even bring disasters to the entire human society.

Finally, the high intelligence of artificial intelligence also means high political. Advanced artificial intelligence gives the technical owner’s outstanding additional advantages, robotic industry, gene sequencing, automatic driving, intelligent finance, smart city, big data processing, natural language processing, image identification, intelligent military system and other artificial intelligence, Change the country’s core competitiveness and economic and social and industrial structure, thereby changing the power structure in many fields.

Because of this, as a big country as the development and application of artificial intelligence, China and the United States play an extremely important role in artificial intelligence, and both parties have unique advantages that other countries cannot copy.How to prevent or reduce artificial intelligence technological advances on the negative impact of global sustainable development and strategic stability requires the work of China and the United States.

In fact, competition in the field of artificial intelligence is not an absolute zero and game, and there is a cooperative development and mutual benefit between parties. China is relatively leading in experimental research and results, and the United States is more leading in basic research and cutting-edge technology exploration. There is a broad cooperative space in both parties.

To this end, China and the United States should be in-depth thinking, work together to launch a formal dialogue on the application of artificial intelligence in safety and economic sectors.Promote the transparency of artificial intelligence research and development, driving its beneficial results to achieve reasonable allocation in a global scale, to minimize the competitive situation that may lead to catastrophic conflicts, and promote the formation of reasonable, benign competition and cooperative relations.

As Kissinger said, China and the United States are the most capable of impacting world progress and peace in technology, political experience and history, and solving the important issues in both parties in cooperation will be China and the United States. Common responsibility for peace and progress.
