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(國(guó)際空間站) 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(機(jī)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.

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

2.How often do the astronauts exercise?
