    Life on the earth depends on the sun.  Day after day, we see its light and feel its warmth. The sun is far away from the earth. It is ninety-three million miles away from the earth. The sun is a large star. The earth is very small among its planets. Every day the sun sends out a great deal of heat and makes us feel hot. But we receive only a small part of the heat, because the sun is so far away from us and its heat loses more of its energy(能量) when it reaches the earth. We also receive a very small part of its light. This is enough for the growth of trees, plants, and humans. On the other hand, much heat and light would do harm(危害) to them. The heat and light from the sun come in just the right quantities(数量) for life on the earth.

Zhao Zheyu, 14, looked at a robot moving around on the stage carefully. In the shape of a truck, the robot got close to a lighted candle. Then it stopped. A small electric fan(电风扇) on the top of it started working. One minute later, the candle went out. "We did it!" Zhao shouted happily with his classmates. They were having a robot class at school.

Like Zhao's school, many middle schools in China have started robot classes in recent years. In the classes, students no longer sit silently in the classroom. They design and make robots. So it's usual to see them walk around, discuss with their teachers and teammates, and use certain tools.

The classes are popular among students. Shi Yingtian, a 14-year-old girl from Beijing, said she liked them because she learned to make things by herself. "You have to put together more than 100 small parts to make a robot. And every part should be put in the right place. I have become more patient and careful after taking these classes for only one year.

Wang Jihua, a robot teacher in Shanghai, thought besides hands-on skills, the most beneficial(有益的) thing robot classes can give to students is to encourage them to take an interest in science.

Zhao is a good example. He said every time he saw his robot move smoothly, he felt a great sense of pride and wanted to learn more. "Maybe I'll become a robot engineer someday. Who knows?" Zhao said.

The old Roger house had been empty for six months, and finally someone was moving in. Betsy didn't see any children getting out of the car, just an older woman in a wheelchair. Betsy thought, "She is going to be lonely by herself." The moving men brought all the furniture into the house. The lady didn't have too many things. Betsy started feeling sorry for her. "Mom, is it alright if I go over to say hello to our new neighbor?" " Why don't you wait until tomorrow?" "Give her a chance to get settled (安顿)."

The next morning they decided to bring some cookies to their new neighbor and introduce themselves. The lady came to the door and said her name was Emily Harris. She invited them into the house. "Please excuse me for the way the house looks," said Miss Harris, "I haven't had much time to put things away and being in a wheelchair makes it twice as hard." Betsy and her mom introduced themselves and stayed only for a short time."We don't want to hold you up,"said Betsy's mom,"If you ever need anything, let us know.""Thanks so much." said Miss Harris.

After breakfast the next day, Betsy decided she wanted to help Miss Harris get settled in.It was Saturday, so she had all day. Betsy really liked Miss Harris. Betsy rang the doorbell but didn' t get an answer. The door was unlocked, so Betsy peeked (窥视) in only to see Miss Harris had tried to reach a shelf and had taken a fall next to her wheelchair. Betsy ran to Miss Harris and asked her if she was alright. "I think I broke my arm," said Miss Harris "  ▲   ，"said Betsy. She ran home and told her mom. They called for an ambulance(救护车). They arrived shortly and took Miss Harris to the hospital.

While Miss Harris was gone, Betsy decided to unpack the boxes that were on the floor and put things away to surprise and help Miss Harris once she returned home. She was going to need a lot of help now that she broke her arm.

When Miss Harris returned home on Sunday, she was surprised by Betsy's hard work. "Thanks a lot, Betsy, "said Miss Harris. "I'm so lucky to have bought this house next to you!" Betsy smiled the biggest smile and said, "Welcome to the neighborhood."

The day before yesterday, a bag of money was missing from the zoo. Mr Safari, the zoo manager, was very1. He wanted to find out who took the money, but it was difficult for him to find out by himself, so he called the police for2. Everyone else was there but Tim, the ticket collector, so the police had to ask the three zookeepers some questions and here is the information they gave.

The keeper of big cats said, "I don't know3Tim is. He was looking very serious today, which is unlike him. He always4when he meets others!"

The keeper of giraffes said, "I saw Tim at about5o'clock. He was in a big hurry."

The elephant keeper said, "I also saw him then. He was carrying a big bag!"

"Tim? Oh no!" cried Mr Safari." l trusted him with the money. How can I feed the animals and pay my keepers now? I'll have to6the zoo."

"Tim7the thief," said one policeman.

At that moment, Tim came running up to them." "I8got it back!" he said." I've been hunting those naughty monkeys since two o'clock. They took a bag of money from my desk,9I had to take a bag of bananas to interest them and make them return the10to me."

"Oh, Tim, I'm sorry to have suspected you!"Mr Safari said." Thank you for saving the zoo!"

When I was young, I was very selfish(自私的). Slowly, my friends all 1 me. I didn't think it was my 2 but criticized(指责) others. My father gave me three examples to help me.

One day, my father cooked two bowls of noodles. One bowl had one egg on top and the other bowl only had noodles. My father let me choose first. 3  I chose the bowl with the egg! To my surprise, there were TWO eggs under my father's noodles! I regretted(后悔) so much! My father said, "Son, you must remember what your eyes see may not be 4 . "

The next day, my father again cooked two bowls of noodles. Again, he let me choose first. This time I chose the bowl without an egg on top. 5 , I didn't find any egg in my bowl. My father said, "Son, you mustn't always 6  experience because sometimes life can cheat you." The third day, my father again made the same 7  . This time, I told my father, "Dad, you choose first. You are the head of the family and does the most for me. I want to 8  you for that." My father chose the bowl with one egg on top. As I ate my noodles, I, found TWO eggs in the bowl! I was 9  but happy. My father smiled and said, "Son, you must remember: when you think for the good of 10  , good things will happen to you!"

I always remember what my father taught me. It helps me a lot in my life.

Haley Evans loves books very much. When she was little, she made a family newspaper with her mother. In third grade, she worked with an  (organize) to collect around 2,000 books for children. In total, she  (donate) about 8000 books so far.

In March 2017, the middle school student from the United States worked on another amazing project. She opened a Free Little Library in Oakland University with her friend Megan MacKenzie.

The Free Little Library is not a new idea. People decorate a box outside their house and fill it  books. People can take or leave any books they want. They are welcome to donate books as well. It is becoming popular in (west) countries.

Hayle came up with  idea after reading about it in the news. In Detroit, US, people make Free Little Libraries for kids who don't have enough money (buy) books.

Megan told the Oakland Post，"I like doing that  I never got to read as much when I was a kid. And it really  (encourage) reading, so hopefully kids can grow up with a real big vocabulary and become more  (interest) in reading.

Haley and Megan's first Free Little Library is mainly for （child）books now. But the girls plan to put in more books for adults.

Do your parents ever say "Act like a lady"1"Be a gentleman" to you? But in the eyes of today's young people,2should a lady or a gentleman be like? Let's take a look.

Kathy3Hong Kong said to us," A gentleman is not a strong, stupid guy. He doesn't get angry easily. He cares about others' feelings. He's always ready to4others."

"When we come to clean up the classroom, a gentleman does the5work. He lets girls6rooms first," Chen Jiaojiao from Shenzhen gave us her7.

Jenny was born in America in 1940. When she was six years old, she couldn't walk because there was something wrong with her left 1. Every weekend, Jenny's mother drove her to see a 2. She said, "My doctor told me I would 3 walk again. But my mother told me I would. I 4 my mother." So she practiced walking day after day.

When she was nine years old, she could run like other 5. Later, Jenny joined a girls' basketball team. She did very well in it.

In 1957, Jenny went to university. She joined the 6 team there. She often practiced 7 with her teammates. In 1960, she went to the Olympics. She won two gold medals, the 100-meter and the 200-meter race.

In 1977, she 8 a book about her life named Wilma. The book was then made into a movie. She said her greatest 9 was creating the Jenny Foundation (基金会) in 1981. 10helped the children who wanted to become sports players. She died in Tennessee in 1994.

If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.

Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks. About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won't just bring faster mobile Internet. People can use it for many other things as well.

For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-when they found something in front, that is too late to stop at once. When the car "sees" something in front, it sends this information to a data center and receives instructions. However, it will be some time before it sends and receives this information. With this kind of lag(滞后), the cars might crash because they don't receive instruction in time. With 5G, this lag will be greatly lowed, making the cars safer.

5G could also be used to power the Internet of Things(IOT), that is, a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. The IOT could be used in a lot of ways. For example, with IOT, your refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside.

My name is Kate. There are many rules in my life. I think these rules are important to me.

At home, I can't play computer games for more than(超过)half an hour. I think it is good for my study because I can have more time to study. I must make the bed after I get up. And I must clean my room every day. So my bedroom is always clean and tidy. My mother says keeping the room tidy is good for my health.

I study at Fuxing Middle School. At our school, we also have some rules. We can't be late for school. So we must arrive at school on time. We must get to school before half past seven in the morning. We need to wear the school uniform every day. In the class, we have to be quiet. We can't listen to music. We can't eat in class. We must eat in the dining hall. After class, we can't run in the hallways.

There was once a king who had a great palace with a wonderful garden. In the garden, there lived all kinds of animals. All of them enjoyed living there.

There was only one thing in the garden that the king hated: an old tree in the center of the garden. It was so old and dry. This made the king so angry that he finally asked some people to cut it down and turned the place into a swimming pool. However, after the tree was cut down, the animals left the garden. Without the animals, the garden was not so beautiful as before. The king was sad, but he didn't know what had happened.

A young man went to the king, and said he could explain what had happened. "This was because you cut the old tree down," said the young man. "There were thousands of moths（飞蛾）which lived in the tree. Birds needed the moths to eat and then they produced wastes for plants to grow. The plants then attracted many other animals to your garden. So your garden became very beautiful. But as you cut the tree down, the animals had to leave."

"Excellent!" Said the king. "I'll make you rich and you will try to make my garden beautiful again."

"I'm afraid it will take many years to finish. It will take many years for the natural balance to get back again," said the young man.

The king was sad, but all he could do was just wait.

Recently, "cloud tourism" has attracted millions of people in China. "Cloud tourism" refers to a new form of travel that depends on high technologies such as 5G and virtual reality (虚拟现实).

During the May Day Holiday, 250 million people took an online tour by livestream (直播) on TikTok (the short video app). Taishan, a popular channel, livestreamed the sunrise at the top of Mount Tai on May 1st and attracted 330,000 views.

China Daily made a survey of 2,000 people on cloud tourism. According to the survey results, 74.8% of them said they were willing to take an online tour and 59.79% said they had a good online traveling experience.

"I hate large crowds and long queues (队列), which make me annoyed when visiting museums in person," said Wang Bo, a museum lover in Beijing. "What's more, ‘cloud tourism' helps cut traveling cost and offers more tourist attractions."

"Cloud tourism" has made huge contributions to the local development and a rise in sales of cultural products after livestreaming shows, according to Xinhua News Agency.

CNN-China launched (发射) another manned mission (载人任务) to its new space station on Sunday, sending three astronauts (宇航员) who will continue space work for six months.

The astronauts lifted off on the Shenzhou-14 spacecraft at 10:44 a. m. , June 5th, 2022, launched from the Jiuquan Satellite Launch Center in the Gobi Desert, Inner Mongolia.

The crew includes Chen Dong, Liu Yang and Cai Xuzhe. Chen was aboard China's Shenzhou-11 manned space mission in 2016 and once held the record for longest stay in space bya Chinese astronaut. Liu became the first ever Chinese woman in space in 2012 on the Shenzhou-9 mission. And this will be Cai's first mission in space. The team will live and work at the Tiangong Space Station's Tianhe core module (核心仓) for six months before returning to Earth. It marks a new step in China's space program.

Six months is the standard mission duration (标准任务期限) for many countries—but it is an important chance for Chinese astronauts to be accustomed to a long-term stay in space and help prepare future astronauts to do the same.

Six space missions have been scheduled (规划) before the end of the year, including another manned mission, two laboratory modules and two cargo missions.

The team aboard Shenzhou-14 will help with the docking, setting up and testing of the two laboratory modules Wentian and Mengtian, which are ready to launch in July and October this year.

Ancient art doesn't have to be boring. Technology in the 21^st century can help to bring it to life by combining(融合) the best of the old and the new.

Along the River During the Qingming Festival

Walking into the China Pavilion at Expo 2010 in Shanghai, people were amazed by seeing a huge digital(数码的) painting. Scientists digitized(数码化) the famous painting Along the River During the Qingming Festisal by Chinese artist Zhang Zeduan.

The original(原先的) painting shows life during the Northern Song period and it includes many details of ancient Chinese customs, lifestyles and technology.

           Farmers work in the fields, sailors move around their boats and people eat and do business in restaurants. Parts of the background are also animated(做成动画). You can see the wind blowing through the trees and across the water. These animations perfectly combine modern technology and ancient art.

Digital technology allows today's artists to express their ideas in ways that ancient artists would not believe possible. Techniques such as animation and 3D digital projection(投影) make art come alive.

Dunhuang Cave Paintings

Dunhuang Caves, which are protected ancient treasures in the Gobi desert in Northwest China, are filled with paintings and sculptures with lasting value. This artwork was created over a period of around 1,000 years.

The good news is for art lovers who cannot travel and for the caves. Scientists have created a 360-degree, 3D digital projection of the caves, which makes the artwork come alive. There is also a function(功能) that lets viewers zoom in and enjoy the paintings and sculptures in greater detail.

Digitising ancient art allows us to explore the ancient practices. It also makes the whole world understand the art while protecting the original artworks for the future.
