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.

Hello, I’m Vladislav. For my summer holidays, I usually stay in a country house near Moscow.
Last summer, my dad’s brother gave me a present—a blue bike. At that time I couldn’t ride it very well.
One day I got into an accident. But don’t worry, everything was OK, just some “little”injuries.
That day, I tried to ride my bike and suddenly it began to move very fast. I couldn’t stop the bike. So I fell into a ditch(沟) full of dirty water. When I thought I had had enough bad luck, a girl walked by. She saw the bike and me. I quickly stood up.
“Are you fishing here?” She asked.
“Yes,”I answered. Then I said,“I’m making fish soup for dinner. Would you like to come?”to my surprise, she agreed.
After that we became friends. Now, we often send each other emails. She knows that I’m studying in China and she asks me questions about Chinese culture. I tell her my stories of China, and she says she wants to visit China, too. She even plans to study Chinese.
This is how, with the help of my bike, China got one more Russian friend.
根据短文内容,回答下列问题。

“How are you?”is a nice question. It’s a friendly way that people in the USA greet each other. But “How are you?”is also a very unusually question. It’s a question that often doesn’t need an answer. The person who asks “How are you?” hopes to hear the answer “Fine”, even if the person’s friend isn’t fine. The reason is that “How are you ?”isn’t really a question and “Fine.”isn’t really an answer. They are simply other ways of saying “Hello.”or “Hi.”Sometimes, people also don’t say exactly what they mean. For example, when someone asks “Do you agree?”, the other person might think, “No, I disagree. I think you’re wrong.”But it isn’t very polite to disagree so strongly, so the other person might say “I’m not sure.”It’s a nicer way to say that you don’t agree with someone. People also don’t exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person say “I’ve to go now.”Often, the person who wants to hang up gives an excuse,“Someone’s at the door.”“Something is burning on the stove.”The excuses might be real, or not. Perhaps the person who wants to hand up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite, and it doesn’t hurt the other person. Whether they are greeting each other, talking about an idea, or finishing a talk, people don’t say exactly that they are thinking. It’s an important way that people try to be nice to each other, and it’s part of the game of language.
根据短文内容,判断下列句子正(T)误(F).
“How are you?”is another way of saying “Hello.”or“Hi.”
It is polite to say “No. I disagree. I think you are wrong.”if you don’t agree with others.
When someone says“I have to go now.”on the phone, it means he wants to go on talking.
“Someone is at the door.”may be an excuse for finishing a phone call.
Sometimes people don’t say exactly what they are thinking about just because they try to be nice to each other.

Different people have different hobbies. For example, some people like reading, some people like swimming and some people like collecting something and so on. I have many hobbies, such as reading, skating, and traveling. I used to read books in my free time. I like reading because I could learn much by reading. At that time, reading was part of my life. Every day, I spent most of my free time reading books, newspapers and magazines. At night, I could hardly get to sleep without a novel in my hand.
But later I found I could only learn from books by reading. I couldn’t get knowledge from others. I needed a change . Traveling is my hobby now. I can visit many different places by traveling. I can learn a lot about people, geography and history. It’s very interesting.
I have many good friends. They all have their hobbies. Ann studies very hard. So her hobby is reading all kinds of books. Tony loves working with her hands, and his hobby is gardening. He usually plants flowers and trees in his yard. Judy is a quiet girl. She likes knitting(编织). She always knits sweaters for her dolls. We have different hobbies, but we are all good friends.
