Here I want to tell you some information about water.

    Water covers most of our planet. People can find it in oceans, lakes and rivers, and under the ground. Water moves in the environment by evaporation, condensation, and precipitation. The warm Sun helps water change into vapour and rise up into the sky. It is evaporation. The vapour in the air forms clouds in the sky. It is condensation. When the clouds get heavy enough, the water falls back to the ground as rain or snow. This is precipitation.

    Ocean water has too much salt in it. Much of the water travels far over the land. When it travels over the land, the water picks up salt from the rocks and soil. About 97.5% of the Earth's water is salty water. It is expensive to take salt out of the water.

    All people need clean water. They need it for drinking, for cooking, and for bathing. Some people in a village in South America did not have clean water. Their water was full of oil and dirty things. People there got sick when they drank the water. Other people heard about the problem. They sent empty water tanks (储水池) to the village. Rainwater fell into the tanks. Now the people in that village have the clean water.

    What's a spacewalk? Any time an astronaut gets out of a spacecraft(航天器) while in space, it is called a spacewalk. Astronauts go on spacewalks for many reasons. For example, experiments can be placed on the outside of a spacecraft. This lets scientists learn how being in space affects(影响) different things. By going on spacewalks, astronauts can also fix things instead of bringing them back to the earth to fix.

    When astronauts go on spacewalks, they wear spacesuits to keep themselves safe. Inside spacesuits, astronauts have the oxygen(氧气) they need to breathe and the water they need to drink. To keep the astronauts and the spacecraft safe, the astronauts must leave and go back to the spacecraft through a special door. When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft. Tethers are like ropes, connect the spacewalkers with the spacecraft. They keep astronauts from floating(漂 浮) away into space. Another way astronauts stay safe during spacewalks is by wearing a SAFER. SAFER is worn like a backpack. It helps an astronaut move around in space.

    How do astronauts train for spacewalks? One way is by going for a swim. Floating in space is a lot like floating in water. Astronauts practice spacewalks underwater in a huge special swimming pool. For every one hour they will spend on a spacewalk, astronauts need to train seven hours in the pool. Another way astronauts practice for a spacewalk is by using virtual reality(虚拟现实). It looks and feels just like a spacewalk.

    Today, only three countries have finished spacewalks independently. They are Russia, the United States and China. The first person to go on a spacewalk in the world was Alexei Leonov from Russia. Zhai Zhigang is the first Chinese astronaut to go on a spacewalk. The world record of spacewalks is held by Russian astronaut Anatoly Solovyev. He has been on 16 spacewalks and spent more than 82 hours outside in space.

Lin Wenqian is a girl student. When she was on a busy bus last month, she felt someone touching her. She was so afraid.

Zhou Bin, 12, is a boy. He likes to chat on the Internet. But once a stranger said lots of dirty things to him.Zhou was so surprised!

What can students do when this kind of thing happens? Here is some advice from some teachers and students:

Don't be afraid. Ask him or her to stop at once. If he or she doesn't listen, try to turn to others around you and call for help.

Keep calm. Be serious and keep a cool face. Say you don't like it and show you are angry.

If there is no one around, use clever ways. If you only shout or fight to make them angry, it could make things worse! They may take your life. Find excuses (借口) to run away. Say things like you are waiting for your parents or you want to go to the washroom.

It is more than sixty years since the death of Lei Feng, and yet his spirit still influences Chinese young people. In fact, the wish to help others can always be found among common people. 

On September 5, 2022, when an earthquake hit Luding, Sichuan, a 28-ycar-old hydropower station (水电站) worker Gan Yu chose not to leave but stay at his workplace. saving villages from being damaged. People think he is a hero like Lei Feng. but he doesn't feel that he should be compared to the young hero. "Lei Feng is a role model to all Chinese young people. The things he did may seem small. but behind them was a great quality that we can all achieve." he said. 

Zeng Qiangfei, 24, is also from Sichuan. In 2013, when an earthquake happened in his hometown, he was studying in a middle school. Zeng remembered seeing rescuers (救援者) and volunteers gather there to help. When he grew up, he became a volunteer himself. After a terrible quake hit Turkey and Syria this year, he flew there to help. During the course, he always saw local people bowing quietly to volunteers like them. "I grew up listening to Lei Feng's stories. He is an excellent young man who tried his best to help others." said Zeng. 

This view is shared by a 56-year-old British man named James Elroy Edginton, who lives in Hunan. the hometown of Lei Feng. Working at a local college. Edginton volunteers to help students from poor families. and is warmly regarded as a "foreign Lei Feng". "I am glad to be connected with the spirit of Lei Feng. His qualities are borderless (无国界的) ." he said. 

Dear Tony,

I go to a new school in Cambridge now. I like it very much. I'm making a lot of new friends. 

I'm studying new subjects, like science. It's very interesting. We're using computers and learning how to use the Internet. We write e-mails(电子邮件) to people in different countries. I'm learning how people live in different countries. It's great!

We do P. E. on Wednesday in the afternoon, Sometimes we stay in the sports hall to do sports and I like that too. I play basketball after school on Mondays. I like playing basketball a lot. I'm enjoying my new school!

Write and tell me what you're doing in your school in China!
