The United States is on the verge of losing its leading place in the worlds 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-olds--the near term source of future PH.D.s-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. PH.D.s in science and engineering declines,the award of PH.D.s 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 Bachelors and Masters degree holders. Too often, promising PH.D.candidates, confronting the cost and financial sacrifice of pursuing their education,find the attraction of industry irresistible.

1.The U.S.will come to lose its leading place in technology probably because ________.

a. the number of PH.D. degree holders is declining b. the number of scientists and engineers is decreasing c. the number of 22-year-ilds is declining d. scientists and engineers are not employed

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

a. technology

b. foreign nationals

c. such fields as law, medicine and business d. postgraduates

3.Large-scale enterprises now need _______. a. bright graduates and postgraduates b. new inventions

c. advanced technology

d. engineers

4.Many promising postgraduates are unwilling to pursue a PH.D. degree because _________.

a. they are not encouraged to be engaged in science b. industry does not require PH.D. holders c. they have financial difficulties

d. they will spend much time and energy completing PH.D. 5.PH.D. candidates "find the attraction of industry irresistible" means that _________.

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

b. they dont think they can prevent themselves from working for industry

c. they cannot resist any attraction from all sides d. they cannot work for industry any longer 14/200𰸣bcadb

In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence C as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed, the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us.

The truly reasonable men who know where the solutions lie are finding it harder and herder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law.

Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each others problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. Talk, talk, talk, the advocates of violence say, a(chn)ll you ever do is talk, and we are none the wiser. Its rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. Possible, my lord, the barrister replied, none the wiser, but surely far better informed. Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.

There are two factors which determine an individuals intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individualthe sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

The importance of environment in determining an individuals intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Marks I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.

1.This selection can best be titled_________. a.Measuring Your Intelligence b.Intelligence and Environment c.The Case of Peter and Mark

d.How the brain Influences Intelligence

2.The beststatement of the main idea of this passage is that _____.

3.According to the passage , the average I.Q.is _____. a.85

b.100

4.The case history of the twins appears to support the conclusion that _______.

a.individual with identical brains seldom test at same level b.an individuals intelligence is determined only by his enviroment

c.lack of opportunity blocks the growth of intelligence d.changes of enviroment produce changes in the structure of the brain

5.This passage suggests that an individual s I.Q.______. a.can be predicted at birth

b.stays the same throuthout his life c.can be increased by education d.is determined by his childhood
