  On May 21, 2000, some American scientists were working at the computers to look for information they needed . Suddenly they saw a lot of very bright red spots crossing the computers’ screens. At the same time the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒). Obviously all these computers had been infected by computer viruses.

It is said that the computer viruses were made by two or three Philippine young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. The kind of computer virus is named I Love You Virus. This virus can hide in computers for long. When the time comes they will attack the computers by lowering the important functions, damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store, what’s worse, it still can reproduce itself in great quantities within a short time.

We come to know that “I Love You” Virus often attacks computers on Mondays and that it is spreading to many computers in the world. Among the countries that suffered computer viruses last year are Britain, Australia, Switzerland and the USA. Those who made the computer muses have been found out slowly and carefully. But till now, how to get rid of the terrible viruses remains a problem.

1.When the viruses attack the computers, the computers will work _______.

  A. normally B. abnormally C. faster D. well

2 .Two or three Philippine young men created the computer viruses to _______.

  A. damage the computers

  B. test their ability quickly

  C. tell the world that they were intelligent

  D. play a trick in operators of the computers

3. According to the passage, computer viruses seem to________.

  A. have been in nature for years

  B. exist in any computers

  C. be able to be got rid of in the near future

  D. be difficult to get rid of at present

4.The most serious damage caused by the viruses is that_______.

  A. the computer’s funtions are lowered

  B. the normal programs are damaged

  C. all the information stored in the computers is gone

  D. the computers infected by the viruses can no longer be used

5. According to the passage, which of the following is true?

  A. Scientists are trying to find a way to get rid of the viruses.

  B. The viruses will come to the new computer after staying in the old one for some time.

  C. Last year four countries found their computers were infected by   viruses.

  D. The “I Love You” Virus is a great harm to human health.

1--5   BCDCA 


解析:

1.根据文章中第一自然段,第三、四句话:To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒). 可以找到正确答案。

2.第二段中第三句 “They created the viruses just to show their intelligence” 表明了他们制造病毒的目的是为了显示智商高,B选项理解为测试能力,这与文中内容有出入。

3.文章最后一句说明如何除去病毒仍是问题,这就证明病毒难以除去。B选项和C选项文中没有提及。

4.根据文章中第二自然段最后一句话: When the time comes they will attack the computers by lowering the important functions, damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store, what’s worse, it still can reproduce itself in great quantities within a short time.可知最佳答案为C。

5.文中只在第二段中提到该病毒可在电脑中潜伏一段时间才发作并复制,并未提到将向其他电脑扩散,所以B不正确。最后一段落中提到了四个受到病毒攻击的国家名称,但这并不表示只有四个国家受到电脑病毒攻击,所以C太狭隘。

When I come across a good article in reading newspapers, I often want to cut and keep it. But just as I am about to do so I find the article on the  1  side is as much interesting. It may be a discussion of the way to  2  in good health, or  3  about how to behave and conduct oneself in society. If I cut the front article, the opposite one is likely to  4  damage, leaving out half of it or keeping the text  5  the title. Therefore, the scissors(剪刀)would  6  before they start,   7  halfway done when I find out the   8  result.

Sometimes two things are to be done at the same time, both worth your  9  . You can only take up one of them, the other has to wait or be  10  up. But you know the future is unpredictable(不可预测的)—the changed situation may not allow you to do what is left  11  . Thus you are   12  in a difficult position and feel sad. How  13  that nice chances and brilliant ideas should gather around all at once? It may happen that your life  14  greatly on your preference of one choice to the other.

In fact that is what  15  is like: we are often  16  with the two opposite sides of the thing which are both desirable like a newspaper cutting. It often occurs that our attention is drawn to one thing only  17  we get into another. The  18  may be more important than the latter and give rise to a divided mind. I  19  remember a philosopher’s remarks: “When one door shuts, another opens in life. ”So a casual(随意的)  20  may not be a bad one.

1. A. front                              B. same

C. either                           D. opposite

2. A. get                           B. keep

C. lead                            D. bring

3. A. advice                        B. news

C. a theory                         D. a report

4. A. suffer                         B. reduce
