九年级英语单项填空中等难度题查看答案及解析
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.
A. much younger B. much lighter C. less creative D. less careful
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
3.The underlined word “eyesight” means “______” in Chinese.
A.凝聚力 B. 想象力 C. 记忆力 D. 视力
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.
