阅读下列两篇短文,然后根据短文的内容,从 A 、 B 、 C 、 D 四个选项中选出一个最佳选项。 

【A】

We are already familiar with computers—computers work for us at home, in offices and in factories. But it is also true that many children today are using computers at schools before they can write. What does this mean for the future? Are these children lucky or not?

Many people who do not know about computers think of them as machines that children play with. They worry that children do not learn from experience but just from pressing a button and that this is not good for them. They think that children are growing not knowing about the real world.

But people who understand more about computers say that computers can be very good for children. A computer can help them to learn about the real world more quickly, to learn what they want to learn and think for themselves. And for the future, don't we need people who can think clearly, who know how to get information quickly and use it well? What do you think?

1.“To be familiar with” means to ______.

A. know nothing B. know about C. dislike D. like

2. Does everyone think computers are good for children?

A. Yes, they do. B. No, not everyone thinks so.

C. They don't know. D. They are not sure.

3. What can computers help children to do?

A. To think clearly, to do homework and to write. B. To play games, to do math and to copy.

C. To think clearly, to get information and to use it well. D. To count, to clean the house and to get information.

4. Does the writer think computer is a good thing?

A. It isn't mentioned. B. No, he doesn't think so. C. He doesn't know. D. Yes, he does.

【B】

Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears.

This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight's stars had started on its journey to you before you were born.

Thus, if we want to be honest, we can't say, “The stars are shining tonight.” We have to say instead, “The stars look pretty. They were shining four years ago, but their light has only just reached the earth.”

1. Light speed is ______ sound speed

A. as fast as B. a million times slower than

C. about millions of times faster than D. about a million times faster than

2. If you stand 200 metres away from a man who is firing a gun to start a race, you will find out that ______.

A. you can hear the sound before you see the smoke B. the sound does not travel as fast as light

C. the sound will reach you before the man fires D. sound travels about a million times faster than light

3. Sunlight obviously ( 明显地 ) ______ than the light of the moon

A. has to travel a greater distance B. moves less quickly

C. travels much more quickly D. is less powerful( 有力的 )

4. The scientific way of saying "The stars are shining tonight" should be ______.

A. the stars have been shining all the time B. the stars seen tonight will shine four years later

C. the stars were shining long ago but seen tonight D. the starlight seen today could be seen four years ago

【答案与解析】

【A】

1. B 词义猜测题。由破折号后的解释“ 电脑在家里、办公室、工厂都为我们工作 ” ,当然我们就已经了解电脑了。

2. B 事实细节题。第2段是说不太了解电脑的人认为电脑对小孩不好,而第3段则说那些懂电脑的人认为电脑对小孩有益,因此,并不是每个人都认为电脑对小孩有益。

3. C 事实细节题。由最后一段,特别是倒数第2个问句可知。

4. D 推理判断题。从最后一段可推断出作者的观点是 “ 计算机是件好东西 ” 。

【B】

1. D 事实细节题。由第 1 段第 1 句可知。

2. B 推理判断题。由第 1 段最后一句推出。

3. A 推理判断题。由第 2 段的第 2 句 ( 太阳光到达地球需要 8 分钟 ) 和第 3 句 ( 月光到达地球仅需 1.3 秒 ) 可推出 ( 太阳光走过的距离明显远于月光 ) 。

4. C 推理判断题。由最后一段的最后一句 They were shining four years ago, but their light has only just reached the earth 可推出。
