People around the world felt excited on the night of April 10, 2019. For the first time in history, people saw a photo of a black hole. The photo became popular immediately(立刻). But do you know it has something to do with a computer scientist Katie Boumna? Without her, there wouldn't be this photo. Black holes are very far from us, so it is very difficult to take photos of them. It's like taking a photo of an orange that is on the moon. Many scientists had tried.
However, none of them succeeded. These failures didn't stop Bouman from trying.
Several years ago, she started working on a special computer program. During the past years, she has improved the program many times. Finally, it turned telescope data (望远镜数据) into a photo of a black hole.
Bouman received lots of praise because of her work. However, the young woman said the success mainly depended on(依靠) her team. "None of us could do it alone," she said.
Would you like to make history as Bouman did? Set a goal for yourself and work hard at it. Maybe you will make it come true in the future.

【推荐2】Mars is the fourth planet from the Sun and the second smallest planet of the Solar System.
It is around two times smaller than Earth with a diameter of 6,779 km. If you stand on Mars and look at the Sun, it will appear about half the size we see it on Earth. Mars is widely known as the red planet. Its red appearance is caused by the rusty iron in the ground.
In many ways, Mars can be considered Earth’s brother. On Mar’s surface, we have discovered the biggest mountain in the Solar System. It is named Olympus Mons, and it is three times bigger than the largest mountain on Earth. A day on Mars is also a little longer than a day on Earth. It lasts about 24.6 hours. A year on Mars, however, or the time that takes for the red planet to circle our Sun, lasts about 687 Earth days. That is almost twice as long as a year on Earth !
In the 19th century, it was believed that life on Mars existed. An astronomer said that he “found” straight lines on Mars’s surface. Many people believed that those were the work of clever life as the straight lines were most likely to be canals for irrigation.
However, as more advanced telescopes were built, it was found that the straight lines were an optical illusion.
To this day, humans are still trying to find out whether there was life on Mars!

【推荐3】As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger.
Scientists have found out that radiation (辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. The damage done by radiation won’t be discovered until their children or even grandchildren are born. Some special medicine may work a little, but no really helpful medicine has been found.
Space junk is also thought to be a great danger to spacemen. It’s reported that there are 9,000 man-made things flying in space. About 30% of these are man-made satellites (卫星), 10% are spaceships, and the rest are space junk. An explosion (爆炸) in 1999 made a cloud of 300,000 fragments , each at least 4mm in size, and even a small piece of these knocked against a spaceship window and did some damage. Scientists are watching and reporting any possible danger all the time. They are working on helpful ways to deal with space junk.
Although space is really dangerous, it interests everyone on the earth. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should care for space and do something to help improve the space environment.

【推荐1】Do you know why different animals or insects have their special colors? They mainly use colors to protect themselves.
Some birds like eating insects, but birds cannot easily catch them. Why? It is because some insects can change their colors with the colors of crops (庄稼). For example, there is a kind of insect. When crops are green, it looks green. As the harvest time comes, it changes to the same brown color as crops have. But some other insects can’t change their colors. So birds or other animals can easily find and eat them. So they have to hide themselves and come out only at night.
If you study the animal life, you will find the main use of coloring is for animals to protect themselves. Bears, tigers and some other animals move quietly through forests. People can’t easily see them because these animals have the colors much like the trees.
Sea animals also have their own way of protecting themselves. Octopus (章鱼) can send out a kind of very black liquid (液体) when it faces danger. So no one can find it, and then it can swim away at once. That’s why it isn’t strong at all, but it can still live up to now.

Three years ago, Bing Dwen Dwen became the mascot (吉祥物) for the Beijing 2022 Winter Olympics.
The design (设计) comes from 5,816 works from 38 countries and areas. Cao Xue, the designer of Bing Dwen Dwen, said the idea first came from the traditional Chinese snack bingtanghulu. But a simple snack couldn’t stand for a country by itself. Cao’s team tried many animals and plants and finally decided on a panda.
However, there were already too many cartoon heroes of pandas. Cao first decided that it should be a baby panda instead of a grown-up panda, so its body is as long as its head.
Cao’s team looked all over the world to collect all the panda designs they could find. They wanted to make sure their panda looked special. They visited the panda nature reserve in Wolong, Sichuan, to get ideas. They found that baby pandas walk in a funny way and can’t stand straight.
Now the panda in an ice shell (外壳) is made into toys and models, as well as printed on notebooks and bags. People of all ages like them very much. “We are pleased with our design as well.” Cao said.

【推荐3】Imagine being in a world like this: one minute you are lying on a beach in Sanya, and the next minute you are at the top of Qomolangma. You do all this without leaving your room. This world is called Metaverse (元宇宙).
Metaverse allows us to go into a virtual 3D space. There we can communicate with people like we do in the real world. For example, if your teacher wants to teach you how to order food in English, in Metaverse, you can walk into a restaurant in London, listen to how people are talking and try to order your food. You don’t even have to leave your room to do this. All you need is a pair of special glasses.
In recent years, more and more people have chosen to talk to doctors online for different reasons. But the fact is, doctors need to see a patient in person to study his or her health conditions. With the introduction of Metaverse, doctors may be able to do more to help the patients online.
However, experts worry that using the Internet for too long can make us connect less with other people. We already use the Internet all the time. Will Metaverse make the time even longer? So, while we’re hopeful about the future of Metaverse, we also need to think about healthy ways to use it.

【推荐1】Birds bring so many wonderful things to our lives. They have beautiful songs for our ears and beautiful feathers (羽毛) for our eyes.
Birds are also added to expressions of different languages. You may have heard “a __▲__ bird flies first”. This Chinese saying means a person who is not talented enough can still go ahead of others by working hard. Another famous one is “to kill two birds with one stone”, which means using one action to hit two goals. And what about “birds of a feather flock together”? That means people with the same interests are often together.
Well, today we will talk about a bird expression that describes getting others unhappy. That is “to ruffle (竖起) one’s feathers”. ”For example, if I were often late for meeting a friend, that could ruffle her feathers. And if someone lied to me, that would ruffle my feathers. This expression also means that your action shakes things up. We use it to describe an action that changes the usual way of doing things.
In English, we have quite a few expressions that mean something similar. To drive someone up the wall, to get under someone’s skin, and to get on someone’s nerves (神经) all mean getting someone unhappy. However, we do not use those expressions to describe changing the usual way of doing things. So, in that sense, ruffling one’s feathers is different.
Word experts say that the use of this expression began in the mid-1800s. It comes from the fact that, sometimes, birds ruffle their feathers when they are scared. But birds also ruffle their feathers at other times, for example, to keep warm or in mating (求偶) seasons.
1. Which word can be put in __________.| A．strong | B．stupid | C．small |

【推荐2】In recent years, more and more Chinese books and movies have been translated into other languages. Many of the translators are young people who have been learning Chinese and are interested in Chinese culture.
Anna Holm wood is one of them. Anna was little known to English readers before she translated Jin Yong’s novel Legends of the Condor Heroes (《射雕英雄传》). After about five years of work, the translated book came out in 2018. And now many English readers have known the name—Jin Yong. Many people think Anna did a good job of explaining things that are “untranslatable”. As a student at the University of Oxford, Anna began to learn Chinese after a trip where she developed a strong interest in China. Like Anna, American translator Jerimiah also learned Chinese in college. He likes reading Chinese books very much and he be-comes more familiar (熟悉的) with Chinese books. “I see China’s strong cultural influence,” he told China Daily.
As more young people learn to translate Chinese texts and films, more Chinese stories will become popular around the world.

【推荐3】①In the 13th century, Marco Polo, the world known Italian traveler, saw many wonderful things in China. One of the things he discovered was money made of paper. People in the West did not have such kind of money until the 15th century. However, the Chinese began to use it in the 7th century.
②Paper was invented by a Chinese man called Cai Lun almost 2000 years ago. But it was not made in Europe until the year 1100. Four hundred years later, a German discovered that he could make the best paper from trees. After that countries rich in forests, such as Canada, Sweden, America and Finland became the most important ones in paper making.
③Paper can be used in many ways. The common uses include newspapers, magazines and books. But do you know that paper can be used for keeping warm? In Finland, the farmers wear paper boots to keep their feet warm in the snow. And even houses can be insulated (使绝缘) from heat or cold with paper.
④However, we have to understand that paper still comes from trees now. If we keep on wasting so much paper, there will not be any trees left on the earth some day in the near future. Every day people throw away about 2800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting down nearly 48,000 tress every day. The fact is that it takes more than 10 years for a tree to grow.
⑤So we must start saving paper right now. We can use both sides of every piece of paper. We can make useful things out of used paper. We can use china cups instead of paper ones. When shopping, we can use fewer paper bags and reuse them if possible.
⑥In short, we should keep a balance between using paper and protecting trees, and do it now before it is too late.

Farmer John and his wife lived on a farm. They raised a pig, a cow and a chicken. One day, a mouse saw that John had set a mousetrap(捕鼠器). He went around the farm and warned all of the other animals about the trap.“There is a mousetrap in the house!” the mouse said to the chicken.
“That’s bad news for you, but it doesn’t bother (打扰）me,” the chicken said.
Then, the mouse went to the pig and the cow. But the pig and the cow did not care either. They said they didn’t have to worry about it and wished the mouse good luck.
One night, a snake got caught in the mousetrap. John’s wife thought the snake was dead and tried to remove it. But the snake was still alive and bit her hand. She became very sick and had a bad fever. The farmer decided to make some chicken soup to treat (治疗) her sickness － so he killed the chicken.

【推荐3】Want to stay away from colds? Put on a happy face.
Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University.
"It seems that positive feelings may reduce the danger of illness," said the study's chief researcher Sheldon Cohen.
In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed feelings were also less likely to tell their doctors that they felt ill.
In this study, Cohen's interviewed 193 adults every day for two weeks. During the interviews, the people told researchers about were given colds by doctors and had to stay alone in a room for six days.
The results showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness are less serious and lasted for a shorter time.
Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.
