The United States is on the verge of losing its leading place in the world’s technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S. scientists and engineers.

Since 1976, employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-old    the near term source of future PhDs is declining. Further adding to the problem is the increased competition for these candidates from other fields    law，medicine，business，etc. While the number of U.S. PhDs in science and engineering declines，the award of PhDs to foreign nationals is increasing rapidly.

Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor‘s and Master‘s degree holders. Too often，promising PH.D.candidates, confronting(面臨) the cost and financial sacrifice of pursuing their education, find the attraction of industry irresistible.

A. scientists and engineers are not employed

B. the number of PH.D. degree holders is declining

C. the number of scientists and engineers is decreasing

D. the number of 22-year-ilds is declining

2. The field of science and engineering is facing a competition from ________ .

D. foreign nationals

3. Large-scale enterprises now need _______.

A. new inventions                B. engineers

C. advanced technology              D. bright graduates and postgraduates

4. PH.D. candidates "find the attraction of industry irresistible" means that _________.

       A. they cannot work for industry any longer

       B. they find industry is attracting more and more college students

       C. they don’t think they can prevent themselves from working for industry

       D. they cannot resist any attraction from all sides

People tend to think of computers as isolated machines, working away all by themselves. Some personal computers do without an outside link, like someone's secret cabin in the woods. But just as most of homes are tied to a community by streets, bus routes and electric lines, computers that exchange intelligence are part of a community local, national and even global network joined by telephone connections.

　　The computer network is a creation of the electric age, but it is based on old-fashioned trust. It cannot work without trust. A rogue (流氓) loose in a computer system called hacker is worse than a thief entering your house. He could go through anyone's electronic mail or add to, change or delete anything in the information stored in the computer's memory. He could even take control of the entire system by inserting his own instructions in the software that runs it. He could shut the computer down whenever he wished, and no one could stop him. Then he could program the computer to erase any sign of his ever having been there.

Hacking, our electronic-age term for computer break-in is more and more in the news, intelligent kids vandalizing（破壞）university records, even pranking (惡作劇) about in supposedly safeguarded systems. To those who understand how computer networks are increasingly regulating life in the late 20th century, these are not laughing matters. A potential for disaster is building: A dissatisfied former insurance-company employee wipes out information from some files; A student sends out a "virus", a secret and destructive command, over a national network. The virus copies itself at lightning speed, jamming the entire network thousands of academic, commercial and government computer systems. Such disastrous cases have already occurred. Now exists the possibility of terrorism by computer. Destroging a system responsible for air-traffic control at a busy airport, or knocking out the telephones of a major city, is a relatively easy way to spread panic. Yet neither business nor government has done enough to strengthen its defenses against attack. For one thing, such defenses are expensive; for another, they may interrupt communication, the main reason for using computers in the first place.
