    My name is Peter. I'm from New York and I am in Qingdao with my parents and my sister Lily now. My sister is eleven and I am twelve. We are in the same school. We go to school from Monday to Friday. Our parents are busy working and they don't have time to drive us to school. So we often go to school by bus. Sometimes we also ride a bike to school. We have four classes in the morning and two in the afternoon. My favorite subject is math. Science is my sister's favorite.

    I like sports. I like playing soccer and basketball very much. But I don't have much time to play them on weekdays. I help my sister with her math on Mondays, go shopping with my mother on Wednesdays, and practice Chinese on Friday afternoons. My Chinese friends help me with my Chinese. But on Saturdays and Sundays I can play sports, watch TV and surf the Internet.

We were tired from all the work. We took turns to sleep.1  of us had to be awake (醒着) all the time. There was so much work to do.

Finally, we reached the space station. There, we would do more work, 2 we would have less pressure (压力). We had so much to do every day in our spaceship. Now there would be more people to help us. We would be able to 3 the work.

When we moved 4 the space station, I felt great. There was so much more space. We would have real 5  to sleep on. We would have better food. They had a 6  in the space station. They grew vegetables.

The six astronauts in the space station were 7  to see us. They said, "We have been8  you."We were also glad to see them. We heard that one of them was sick(生病的). We went to visit her together."9  are you feeling now?"we asked her. She said she was 10 . We also felt less worried.

The first night in the space station was great. We had a good dinner. Then we were going to 11 . I had been working for hours. But one of the astronauts said, "We need to give you a 12  . Each person has to take turns to stay awake. Here is the schedule(日程安排)."I saw I was the 13  . I would have to stay awake tonight. 14  I was really tired. But I knew it was my job so I 15 .

I became an astronaut so that I could travel in space. Now I'm here. It is hard work, but it's exciting.
