Passage Two:Questions 16 to 20 are based on the following passage.Sport is not only physic
ally challenging, but it can also be mentally challenging. Criticism from coaches, parents, and other teammates, as well as pressure to win can create an excessive amount of anxiety or stress for young athletes (运动员). Stress can be physical, emotional, or psychological, and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.

The early years of development are critical years for learning abut oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents’ and coaches’ criticisms to heart and find a flaw (缺陷) in themselves.

Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game, many parents and coaches focus on the outcome and find fault with youngsters’ performances. Positive reinforcement should be provided regardless of the outcome. Research indicates that positive reinforcement motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.

第16题:An effective way to prevent the burnout of young athletes is ________.

A) to make sports less competitive

B) to make sports more challenging

C) to reduce their mental stress

D) to increase their sense of success

As Dr. Samuel Johnson said in a different era about ladies preaching, the surprising thing
abut computers is not that they think less well than a man, but that they think at all. The early electronic computer did not have much going for it except a marvelous memory and some good math skills. But. today the best models can be wired up to learn by experience, follow an argument, ask proper questions and write poetry and music. They can also carry on somewhat puzzling conversations.

Computers imitate life. As computers get more complex, the imitation gets better. Finally, the line between the original and the copy becomes unclear. In another 15 years or so, we will see the computer as a new form. of life.

The opinion seems ridiculous because, for one thing, computers lack the drives and emotions of living creatures. But drives can be programmed into the computer's brain just as nature programmed them into our human brains as a part of the equipment for survival.

Computers match people in some roles, and when fast decisions are needed in a crisis, they often surpass them. Having evolved when the pace of life was slower, the human brain has an inherent defect that prevents it from absorbing several streams of information simultaneously and acting on them quickly. Throw too many things at the brain at one time and it freezes up.

We are still in control, but the capabilities of computers are increasing at a fantastic rate, while raw human intelligence is changing slowly, if at all. Computer power has increased ten times every eight years since 1946. In the 1990s, when the sixth generation appears, the reasoning power of an intelligence built out of silicon will begin to match that of the human brain.

That does not mean the evolution of intelligence has ended on the earth. Judging by the past, we can expect that a new species will arise out of man, surpassing his achievements as he has surpassed those of his predecessor. Only a carbon chemistry enthusiast would assume that the new species must be man' s flesh-anti-blood descendants. The new kind of intelligent life is more likely to be made of silicon.

What do you suppose was the attitude of Dr. Samuel Johnson towards ladies preaching?

A.He believed that ladies were born worse preachers than man.

B.He was pleased that ladies could preach, though not as well as men.

C.He disapproved of ladies preaching.

D.He encouraged ladies to preach.

It is hard to predict how science is going to turn out, and if it is really good science i
t is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful hits,

The only solid piece of scientific truth abut which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th. century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.

But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can' t be answered, sooner or later, including even the matter of consciousness. To be sure, there may well be questions we can't think up and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.

According to the author, really good science ______.

A.would surprise the brightest minds of the 18th century Enlightenment

B.will help people to make the right choice in advance

C.will produce results which cannot be foreseen

D.will bring about disturbing results

Every year thousands of grey whales make the longest migration of any animal, traveling
7,000 miles each way between the Arctic and Baja, California. The grey whales spend the long summer days in their Arctic feeding grounds in the Bering Sea between Alaska and Russia. Unlike a fish, the whale is warm-blooded and must therefore maintain a relatively high internal body temperature. In the cold Arctic waters the grey whale is protected by an outer layer of blubber which averages six inches in thickness. Other whales such as the Greenland Night whale have been found with a two-foot thick layer of blubber covering their bodies.

2. During these summer months, in the Arctic the grey whales fatten themselves by consuming enormous quantities of small shrimp-like animals called amphipods. Recent observations of a young grey whale, Gigi Ⅱ, held in captivity at Sea World in San Diego during 1971 and 1972, suggest that the grey whale feeds by sweeping its enormous head over the bottom. The amphipods on which it feeds are either stirred off the bottom or leap off the bottom to escape. These animals and the surrounding water are sucked into the whale&39;s mouth. As the water is expelled from the mouth, it passes through coarse baleen fibres. The small animals are trapped and swallowed.

3. In October as the days get shorter and ice begins to form. over the Arctic feeding grounds, the California grey whale begins its long journey south to the warm waters of Baja, California. During this three-month long trip the whales travelling in groups stay close to the shore of North America, swimming both day and night and averaging abut 100 miles per day.

4 During the trip south the grey whales that are sexually mature, at least three years old, and not pregnant already, form. mating groups. These groups are composed of three whales, two males and a female. The dominant male couples with the female while the second male is kept busy positioning the two whales on their sides facing each other and keeping them together during the sex act. This is no small job, since each whale can be fifty feet long and weigh forty tons.

5. During December and January the grey whales arrive at the warm lagoons along the coast of Baja, California. The whales swim miles inland along narrow shallow channels. These channels are the breeding grounds of the California grey whale. The calf has been gestating in the pregnant female for the last thirteen months, that is, since her last journey south. The expectant cow is aided in the birth of the calf by another female that acts as a midwife. At birth the calf sinks toward the sea floor. Being a mammal the whale must breathe at the surface. The midwife guides the baby whale to the surface for its first gulp of air. The calf then finds its mother&39;s nipples and rich whale milk is forced into its mouth. During the next two months the calf will grow twenty feet and double its weight.

6. In March the whales begin their long journey north to the Arctic. The newly-pregnant females leave first, following by the males and immature females. The last to leave the warm waters of Baja are the females and their calves. The whales arrive at their Arctic feeding ground in June. Many scientists believe that during this entire eight month long, 14,000 mile journey, the California grey whale does not feed at all!
