What can make people cheer in every corner of the world? The answer can only be soccer, the world's most-loved sport.

December 9 is celebrated as World Soccer Day in China. Fans show their love for this sport by having soccer games. But for many people, it's not just a simple game-it's a way of life. According to FIFA(足球国际管理机构), 3,570 million people enjoyed the 2018 World Cup in Russia. That's about half of the world's population! Over 240 million people in more than 200 countries play soccer today.

There are facts about the amazing game. The earliest form of soccer was from China. It was called cuju(蹴鞠). Players had to kick a ball into a net. They couldn't use their hands, But modern soccer was invented in England. In 1863, the English Football Association was set up. It made the rules of modern soccer. Scotland(苏格兰)and England played the first official(官方的)international soccer match in 1872. The score of the match was 0-0. About 4, 000 people enjoyed it. The first soccer match shown on TV was in 1937. Soccer players run an average(平均)of 6 miles, about 10,000 meters, during every game.

The year 2020 is a special one for China, as the Chinese government has set a goal of lifting all the people out of poverty(贫困)by the end of the year. To achieve this goal, one important task is to reduce the education gap(差距)between the poor countryside and the cities.

In recent years, the governments have worked hard to improve the education in poor areas. Schools have put great efforts into improving education in these areas. More new schools have been built, and more money has been used to help students from poor families. Let's have a look at how the students across the country have benefited(得益)from this.

"Do you like playing football?" asked British teacher Matthew.

"I prefer to play basketball," answered Wang Qi.

These "dual-teacher classes"(双师课堂)were set up by China Daily. Through an online video talk, the foreign teachers are teaching students from the poor areas. The goal is to bring better English education to poor areas.

He Jiao is a student from Dafang, Guizhou. In 2015, when she was admitted(录取)to Tsinghua University, her family were nervous about her tuition fees. Her father made no more than 1,000 yuan a month.

Thanks to a project started by the local government, He Jiao received a scholarship(奖学金)of 100,000 yuan, and her university dream came true.

We have been used to wearing masks(口罩)in public since February. About 300 million masks are used and then thrown away every day in China. Where do these masks go? You might think they just go in a rubbish bin. But that's just the first stop on the masks' journey.

After the masks are thrown into the bins, rubbish trucks empty the bins and take the rubbish to landfills(垃圾场). Next, the masks will be taken to rubbish incinerators(焚化炉)and burned. Burning masks might not seem to be very good for the environment. Won't it cause pollution?

The answer is "no", according to China Daily. The main material of most masks is polypropylene(聚丙烯). It's non-toxic(无毒的). After burning, it changes into water and CO₂.

In fact, burning the masks can bring some benefits(益处). The process of burning the rubbish can produce electricity. Burning one ton of rubbish can produce more than 400 kilowatt hours(度)of electricity. Some people make a prediction that there will be 162,000 tons of used masks in China this year. Burning all of them can produce more than 64 million kilowatt hours of electricity. This is enough to make an electric car drive about 370 million km, which is 9,250 times as long as the earth's equator.

At last, the slag(残渣)from burning masks can be recycled to make bricks(砖块)or fill the roads.

There are many people we should say thanks to. Zhang Wenhong is one of them. When we were    51    against COVID-19(新肺炎)and had to stay at home, I always read news and    52    videos about it. Zhang Wenhong caught my eyes. He is good at treating(治疗)COVID-19. I am interested in him not only for his medical skills but also his humorous sense. He and his team write many    53    about treating COVID-19. He also gives us lots of ways on how to protect    54    . His humorous sense makes us understand COVID-19    55    . Thanks to him, we can deal with the problems that we have.

It’s sad to learn that a whale has died in the ocean. However, that is not the end for the whale. It gives a lot to other sea animals after death.

When a whale dies, it quickly drops to the bottom of the ocean floor. There the whale’s dead body provides food and nutrients(营养) for deep-sea animals. The remains(残骸) can last(持续) for ten years and build an ecosystem called a whale fall — an “oasis(绿洲)” of life in the deep sea.

Chinese scientists found a whale fall for the first time in the South China Sea this year. The whale fall ecosystem can stay in the deep ocean because of great pressure and cold temperature there. They can stop the body from decomposing(分解) too quickly. The depth(深度) makes it hard for scientists to find the whale fall. There are less than 50 known whale falls in the world.

The whale fall in the South China Sea is about three meters long. Scientists have found several species(物种) near the whale fall. Some fish have started to eat the whale’s tail. A scientist named Xie Wei says the whale fall might be quite recent and needs long-term observation(观察). By studying the whale fall, scientists can better understand how sea ecosystems support life.
