An astronaut’s work may sound exciting, but living in space isn’t as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them.

When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts’ fingernails(手指甲) and even make them fall off.

In space, you don’t have many choices in what you eat. It’s hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs(碎屑). Crumbs could fly around everywhere.

In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting(喷水) gun and a washcloth.

Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they’re in space to try to keep their bones strong as long as possible.

Perhaps the hardest part of life in space is the feeling of loneliness. Astronauts sometimes have to spend weeks and even months away from Earth. They miss their friends and families.

Do you like to sit in front of the computer and play computer games hour after hour? Have you ever thought of what that may be doing to your health? More and more children are becoming overweight(肥胖的) and growing less creative because they spend too much time in front of the computer according to a survey.

Last week Child Protective Services(儿童保护组织)in America organized an activity. The aim of the activity was to encourage children to do some outdoor activities instead of playing computer games at home. Many American children spend about 1,000 hours a year playing computer games — more time than they spend in school. As a result, they are overweight. Some of them have very poor eyesight, and they can’t see clearly.

Everyone should pay attention to his health and try to keep healthy. The doctor says that the longer children play computer games, the more overweight they may become. And the junk food children eat while they’re playing computer games makes the weight problem more serious.

To keep fit, children need to take exercise regularly, play outside with friends, and explore the world around them. Can you spend two weeks without playing computer games? It might be difficult for computer lovers, but why not have a try?

1.Children may become______ if they play computer games all day.

2.American children may spend______ hours in school a year according to the passage.

A. less than 1,000 B. more than 1,200 C. about 1,500 D. about 2,000

4.What can we learn from the passage?

A. Playing computer games has caused some health problems.

B. Playing computer games can make children cleverer and more creative.

C. Child Protective Services in America organized an activity for parents.

D. Child Protective Services asked children to study at home and not to play outdoors.
