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.

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。 |

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were 36 to show that we all have “a body clock” 37 us, which controls the 38 and fall of our body energies, 39 us different from one day one to the next.
The 40 of “a body clock” should not be too 41 since the lives of most living things are controlled 42 the 24 hour night-and-day cycle. We feel 43 and fall asleep at night and become 44 and energetic during the day. If the 24 hour-cycle is 45 , most people experience unpleasant 46 . For example, people who are not 47 to working at night can find that 48 of sleep causes them to 49 badly at work.
50 the daily cycle of sleeping and 51 , we also have other cycles which 52 longer than one day. Most of us would 53 that we feel good on some days and not so good on 54 ; sometimes our ideas seem to flow and at other times, they 55 do not exist.

The Ministry of Education has spared no efforts to bring on IT learning. What is its main aim? Is it to teach students how to learn the computer or is it meant to change the usual method of teaching in order to 1 students’ strong interest in computers?
Teaching students computer knowledge and skills is different 2 giving class lessons through the use of computers. And schools are beginning to pay much attention to using computers to teach students. There is 3 about the fact that IT learning plays an important role as a new teaching tool in this day of technology. 4 ,views differ on whether the schools can achieve their targets, as success 5 whether they can make use of computers effectively.
Let’s take the subject of Chinese as an example and see 6 difficulties the experts face in their IT management. At present,20 percent of lessons are given with the help of computers. In other words, in a period of 10 weeks, a Chinese-language teacher must spend two weeks to teach the subject 7 .In carrying out such a major policy as IT learning, the experts should know the 8 that different teachers teaching different subjects have different demands, thus making it 9 to see the policy through.
Some teachers, having already got some computer knowledge, will still be forced to 10 the training courses with those who have zero knowledge about computer.
Another problem is that new teachers may be sent to work in schools 11 IT learning has just started. All teachers—including the seniors who are very 12 in teaching, but who suddenly have no idea what to do when it comes to computers will have to 13 from the very beginning. They will become 14 and their teaching performances may be badly affected. The experts have found out how much of each subject is taught by computers in every school, and have 15 all schools to complete the given work. A hard-pressed teacher may put the daily teaching 16 or the courses onto the computer just to order the required time for IT learning and then 17 the usual way. Furthermore, he may leave school work to his 18 through the computer before class comes to an end in order to “complete” his IT learning 19 . 20 the teaching of the Chinese language is concerned, do computer lessons really achieve the desire goals to raise the students’ level of Chinese, pass on common values and so on? I am not so sure.
