Questions 56-61are based onthe following passage.
Educators today are more and more oftenheard to say that computer literacy is absolutely necessary forcollegestudents. Many even argue that each incoming freshman should have permanentaccess to his or her ownmicrocomputer. What advantages do computers offer thecollege students？
Any student who has used a word processorwill know one compelling reason to use a computer: to writepapers. Although notall students feel comfortable composing on a word processor, most ,findrevising and editingmuch easier on it. One can alter, insert, or delete just bypressing a few keys, thus eliminating the need to rewrite orre-type.Furthermore, since the revision process is less burdensome, students are morelikely to revise as often as isnecessary to end up with the best paperpossible. For these reasons, many freshman English cottrses require the useof aword processor.
Computers are also useful in the contextof language courses, where they are used to drill students in basicskills.Software programs reinforce ESL(English as a Second Language .instruction, aswell as instrnction in French, German, Spanish, and other languages. By usingthese programs on a regular basis, students can improvetheir proficiency in alanguage while proceeding at their own pace.
Science students take advantage ofcomputers in many ways. Using computer graphic capabilities, forexample, botanystudents can represent and analyze different plant growth patterns. Medicalstudents can learn tointerpret computerized images of internal body structures.Physics students can complete complex calculations farmore quickly than theycould without the use of computer.
Similarly, business and accountingstudents find that computer spreadsheet programs are all but indispensabletomany aspects of their work, while students pursuing careers in graphic arts,marketing, and public relations find thatknowledge of computer graphic isimportant
Education majors learn to develop grading systems usingcomputers,while social science students use computers for analyzing andgraphically displacing their research results.
It is no wonder, then, that educatorssupport the purchase and use of microcomputers by students. A Versatile tool, the computer can help students learn.And that is, after all, the reason for going to college.

第3题
Although he is so wealthy, Bill Gates does not want to give up. He is still very interested in his vision and he travels the globe, making quick stops in cities to sell the new software products of his company.
The central vision of Bill Gates is the “information highway”. This is a network for computers that will link every home, office and shop in the future. This computer network system will have an effect on business, shopping and education. Bill Gates says that the main use of this new technology will be in communication. It will be a way to find people with common interests and to share opinions with them.
But is this communication by computer along the “information highway” really a good thing？ Won’t we be sitting at home, only “socializing” with our computer, paying big companies money so that we can receive information that some large communication corporation somewhere had decided is “acceptable” for us to read？ No, says Bill Gates, he thinks that the phrase “information highway” is a terrible phrase. It makes people think that we are all going down the same road, he says. In fact, the computer network will let us choose our own intellectual direction. It will give us freedom. It will also bring good to society, because it will allow for the spread of education. When more and more people receive education, the gap between the rich and the poor will narrow.
In the meantime, however, the gap between the rich and the poor is still there. To be added to this now is the gap between those with computers and those without.
1.Ever since he was a college student, Bill Gates has __________.
A. become very interested in the computer
B. set up a goal to popularize the computer
C. discovered great potentials in computer business
D. dreamed of having a giant computer company
2.Bill Gates’ success depends on the following except ___________.
A. his vision and his travel over the globe
B. his technical skills and business marketing skills
C. his deep personal interest in developing computer science
D. his strong desire to make big money
3.The word “vision” (line 2, parA.2) probably means________.
A. sight
B. idea
C. effort
D. daydream
4.The “information highway” will mainly be used _______.
A. in human communication
B. to help link every home, office and shop
C. in business, shopping and education
D. to narrow the gap between the rich and the poor
5.The best title for this passage is probably _________.
A. Bill Gates, his Vision and Mission
B. Computer and Information
C. Advantages of the Computer Network
D. One of the World’s Computer Giants

For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up-to-date. They're documenting why teaching is such a fruitful way to learn, and designing innovative ways for young people to engage in instruction. Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who're learning only for their own sake. But how can children, still learning themselves, teach others？ One answer: They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings (兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They engage college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic. But the most cutting-edge tool under development is the "teachable agent"—a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil. Computer scientists have created an animated (动画的) figure called Betty's Brain, who has been "taught" about environmental science by hundreds of middle school students. Student teachers are motivated to help Betty master certain materials. While preparing to teach, they organize their knowledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking. Feedback from the teachable agents further enhances the tutors' learning. The agents' questions compel student tutors to think and explain the materials in different ways, and watching the agent solve problems allows them to see their knowledge put into action. Above all, it's the emotions one experiences in teaching that facilitate learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they derive pride and satisfaction from someone else's accomplishment. 1. What are researchers rediscovering through their studies？ A.Seneca's thinking is still applicable today. B.Better learners will become better teachers. C.Human intelligence tends to grow with age. D.Philosophical thinking improves instruction.
A、Seneca's thinking is still applicable today.
B、Better learners will become better teachers.
C、Human intelligence tends to grow with age.
D、Philosophical thinking improves instruction.
第5题
That may not sound like very long. However, it could give people time to get under a table. The flow of electric power or gas could be cut, air traffic controllers could warn away pilots. Even so-called “smart buildings” could be designed to get ready.
Richard Allen of the University of Wisconsin and Hiroo Kananmori of the California Institute of Technology developed the program. They call it the Earthquake Alarm System. A report published in Science magazine describes it.
The system uses a mathematical program to measure information collected by instruments placed across the Los Angeles area. Southern California already has more than 150 stations that measure movements within the ground. The information they collect is sent to a high-speed computer.
The new system is designed to estimate the strength of the earthquake once the shaking starts. Areas directly above the center of the earthquake would have the least warning. Distant places might have as long as forty seconds.
Professor Allen notes that an early warning system for earthquakes would require a major campaign of public education. Then, another problem is the possibility of false alarms.
48. When an earthquake strikes, the new alarm system would give people enough time to______.
A.find shelter in “smart buildings”
B.tell pilots to land the airplanes
C.know the strength of the earthquake
D.turn off gas and electricity
49.The “earthquake Alarm System” described in the passage has been developed by ______.
A.Richard Allen and his teacher Hiroo Kananmori
B.Hiroo Kananmori and his assistant Richard Allen
C.two scientists from the United States and Japan
D.two scientists from two universities in the US
50. The new alarming program_________.
A.is widely used in Winsconsin and California
B.is still in process of development
C.is especially useful for areas directly above center of the earthquake
D.gives warming at least forty seconds before the earthquake starts
51. The new alarm system may be described as _________.
A.a program that analyzes data across the United States
B.a network of instruments placed across the United States
C.a program to collect information from 150 different stations
D.a very powerful computer that can do mathematical problems
52. The writer of this passage has most probably used information from_________.
A.a meeting held at the California Institute of Technology
B.an interview with Professor Richard Allen
C.a report published in the Science magazine
D.an announcement made by a group of scientists
