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.

“You are my best friend.” It’s the nicest thing you can    36    to someone. It’s also the nicest thing you can    37   someone.
Good friendships begin in middle school. It’s the    38   you begin to develop your own personality. Your parents aren’t around so you    39   lots of time every day sharing your life with your classmates. You talk with them, you work with them and you become friends with them. But    40   them will become your “best” friend.
Best friends are the people who like you and    41    you the most. They are the    42   who are easy to work with and easy to have fun with.
Sometimes it’s    43   to find a best friend. And sometimes you can     44   a little lonely. But just because you don’t have best friend now, it doesn’t mean you    45    one in the future. Best friends seem to find each other as if by magic. And when you find your best friend, the magic will last forever.
