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 families 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.

1.We probably read the passage from______.

A. a report card　　 B. a letter　　 C. an e-mail　　 D. a science magazine

2.How often do the astronauts exercise?

When astronauts （宇航员）are in space, they eat, sleep, wash, work and play. They do the same things as us, but they do them differently. On Earth, we put food on a plate and water in a glass. Gravity (重力) holds the food down and keeps the water in the glass. But in space, there is almost no gravity. So food can float away, and astronauts must eat and drink carefully.

Sleeping is very different in space. Some astronauts like to float in the air, but most astronauts like to be in a sleeping bag. They tie the bag to a wall so that they can’t float away.

Washing is difficult. There is no shower or bath, so astronauts must use a wet sponge（海绵）. They brush their teeth normally, but very carefully. They don’t want wet toothpaste to float around the spacecraft（太空舱）! Toilets are easy to use. A space toilet is like a vacuum (真空) cleaner with a seat.

Exercise is very important in space. On Earth, your legs carry your body, but in space, astronauts float, so they do not use their legs. This is very bad for their legs, so they must exercise for thirty minutes every day. They often use an exercise bicycle for this.

After a day’s work, astronauts relax（放松）. They listen to music, read, watch films, play games, write e-mails or talk to their friends and families by radio. Sometimes they just enjoy floating in the air. On the international Space Station, astronauts sometimes race from one end of the station to the other. The most popular pastime（娱乐） is looking out of the window, looking at space and watching the Earth.

根据上文完成以下给宇航员的建议，每空一词

1.Eat and drink carefully because food and water can __________away.

2.Tie your sleeping bag to a __________ before sleeping.

3.Wash with a __________ sponge.

4.Exercise for __________an hour every day.

5.Bring music books and videos with you so that you can __________.
