3. We need to ________ a plan to save the environment.

Life in space is much different from life on earth. How do astronauts live in space?

Eating In the past, astronauts could eat only small pieces of dried food. But now astronauts are able to eat more everyday food like fruit, vegetables and ice cream.

Sleeping All the people in the ISS(国际空间站) have their own rooms. They have to tie(系) themselves to their beds, or they’ll fly away! That seems like a strange way to sleep, but astronauts say sleeping in space is really not too bad.

Exercising This is more important in space than on earth. Astronauts exercise on bikes and other machines(机器) for about two hours every day. That way, they can still be healthy when they get back home.

Having fun Astronauts can read books, play cards, listen to music or send e-mails to their friends and family when they aren’t working. Sometimes they just sit and look out of the window. It’s also much fun!

Astronauts are hardworking whether in space or on the earth. Though the work sometimes is difficult, they are still interested in it and love the job. Many people think their lives are very interesting and their dream jobs are to be the astronauts.

One of Tom’s feet is bigger than the other. “I can never find shoes for my feet,” he says to his friend, Dave.

“Why don’t you go to a shoemaker?” Dave says, “A good one can make you right shoes.” “Well, aren’t they expensive?” Tom asks.

“No,” Dave says, “some of them aren’t, there is a good one in our village, and it is quite cheap. Here is his address.” He writes something on a piece of paper and gives it to Tom.

Tom goes to the maker in Dave’s village a few days later, and asks the shoemaker to make him some shoes.

A week later, Tom goes to the shoemaker again and says to the shoemaker, “You are foolish! I tell you to make one bigger than the other, but you make one smaller than the other.”

How are you？Thanks very much     51     your last letter. I have finished all my exams.

The last one was history yesterday. I think   history   is   really   difficult     52     there are lots of facts and dates to remember. I have a poor memory ( 记忆力) and I hate to remember things. I am afraid I did not     53     the exam.

This term, I took eight     54     in total( 总 计 ) . The worst were history and French( 法语 ) . I found them boring and hard to learn. I have already forgotten most     55     teacher taught me. I need to study     56     than before.

I like geography best, but we only had it     57     a week. Our geography teacher, Mr.

Hill, was great. He taught us very     58    . He did not give us too much homework.

We did a project with Mr. Hill about a few countries in Europe and Asia. Some of my classmates went to the library to     59     for photos and I used the Internet to search for   some information. Mr. Hill gave us a lot of     60     advice. We could finish   our report   easily.

Please write and tell me about your year at school.

Yours,

David
