PART V READING COMPREHENSION [25 MIN]

In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.

TEXT A
At some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don’t act on your impulse, but let it pass instead. You know that to commit the action is wrong in some way and that other people will not accept your behavior.
Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject.
One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is topic that Americans talk about constantly. It’s not taboo to talk about fat; it’s taboo to be fat. The “in” look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious society like the U.S., thin is “in”, fat is “out”.
It’s not surprising, then, that millions of Americans have become obsessed with staying slim and “in shape”. The pursuit of a youthful physical appearance is not, however, the sole reason for America’s fascination with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people’s bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising.

C.their appreciation of the importance of exercise.
D.the encouragement they have received from their companies.
TEXT B
The discovery of the Antarctic not only proved one of the most interesting of all geographical adventures, but created what might be called “the heroic age of Antarctic exploration”. By their tremendous heroism, men such as Shakleton, Scott, and Amundsen caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modern science and inventions are revolutionizing the endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogs that earlier discoverers found so invaluable and hardly comparable.
Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the maping of the whole of the interior presents a formidable task to the cartographers who undertake the work. Once their labors are completed, it will be possible to prospect the vast natural resources which scientists believe will furnish one of the largest treasure hoards of metals and minerals the world has yet known, and almost inexhaustible sources of copper, coal, uranium, and many other ores will become available to man. Such discoveries will usher in an era of practical exploitation of the Antarctic wastes.
The polar darkness which hides this continent for the six winter months will be defeated by huge batteries of light, and make possible the establishing of air-fields for the future inter-continental air services by making these areas as light as day. Present flying routes will be completely changed, for the Antarctic refueling bases will make flights from Australia to South America comparatively easy over the 5,000 miles journey.
The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has shown that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his parties were men who had never seen snow before, and yet he records that they survived the rigors of the Antarctic climate comfortably, so that, provided that the appropriate installations are made, we may assume that human beings from all countries could live there safely. Byrd even affirms that it is probably the most healthy climate in the world, for the intense cold of thousands of years has sterilize this continent, and rendered it absolutely germfree, with the consequences that ordinary and extraordinary sickness and diseases from which man suffers in other zones with different climates are here utterly unknown. There exist no problems of conservation and preservation of food supplies, for the latter keep indefinitely without any signs of deterioration; it may even be that later generations will come to regard the Antarctic as the natural storehouse for the whole world.
Plans are already on foot to set up permanent bases on the shores of this continent, and what so few years ago was regarded as a “dead continent” now promises to be a most active center of human life and endeavor.

TEXT C
Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changing sensitivity to some hormones are essential aspects of the phenomena of aging.
Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secret chemical agents that are conveyed by the bloodstream and regulate distant target organs or tissues. Bayliss and starling demonstrated that chemical integration could occur without participation of the nervous system.
The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excite or set in motion. The term “endocrine” was introduced shortly thereafter “Endocrine” is used to refer to glands that secret products into the bloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands that secret their products though ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through a duct into the intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless.
11. What is the author’s main purpose in the passage?
A.To explain the specific functions of various hormones.
B.To provide general information about hormones.
C.To explain how the term “hormone” evolved.
D.To report on experiments in endocrinology.
12. The passage supports which of the following conclusions?
A.The human body requires large amounts of most hormones.
B.Synthetic hormones can replace a person’s natural supply of hormones if necessary.
C.The quantity of hormones produced and their effects on the body are related to a person’s age.
D.The short child of tall parents very likely had a hormone deficiency early in life.
13. It can be inferred from the passage that before the Bayliss and Starling experiments, most people believed that chemical integration occurred only___
A.during sleep.
B.in the endocrine glands.
C.under control of the nervous system.
D.during strenuous exercise.
14. The word “liberate” could best be replaced by which of the following?
A.Emancipate
B.Discharge
C.Surrender
D.Save
15. According to the passage another term for exocrine glands is___.
A.duct glands
B.endocrine glands
C.ductless glands
D.intestinal glands.
TEXT D
If the old maxim that the customer is always right still has meaning, then the airlines that ply the world’s busiest air route between London and Paris have a flight on their hands.
The Eurostar train service linking the UK and French capitals via the Channel Tunnel is winning customers in increasing numbers. In late May, it carried its one millionth passenger, having run only a limited service between London, Paris and Brussels since November 1994, starting with two trains a day in each direction to Paris and Brussels. By 1997, the company believes that it will be carrying ten million passengers a year, and continue to grow from there.
From July, Eurostar steps its service to nine trains each way between London and Paris, and five between London and Brussels. Each train carries almost 800 passengers, 210 of them in first class.
The airlines estimate that they will initially lose around 15%-20% of their London-Paris traffic to the railways once Eurostar starts a full service later this year (1995), with 15 trains a day each way. A similar service will start to Brussels. The damage will be limited, however, the airlines believe, with passenger numbers returning to previous levels within two to three years.
In the short term, the damage caused by the 1 million people-levels traveling between London and Paris and Brussels on Eurostar trains means that some air services are already suffering. Some of the major carriers say that their passenger numbers are down by less than 5% and point to their rivals-Particularly Air France-as having suffered the problems. On the Brussels route, the railway company had less success, and the airlines report anything from around a 5% drop to no visible decline in traffic.
The airlines' optimism on returning traffic levels is based on historical precedent. British Midland, for example, points to its experience on Heathrow Leeds Bradford service which saw passenger numbers fold by 15% when British Rail electrified and modernized the railway line between London and Yorkshire. Two years later, travel had risen between the two destinations to the point where the airline was carrying record numbers of passengers.
16. British airlines confide in the fact that__.
A.they are more powerful than other European airlines.
B.their total loss won’t go beyond a drop of 5% passengers.
C.their traffic levels will return in 2-3 years.
D.traveling by rail can never catch up with traveling by air.
17. The author’s attitude towards the drop of passengers may be described as__.
A.worried.
B.delighted
C.puzzled.
D.unrivaled.
18. In the passage, British Rail (Para 6) is mentioned to__.
A.provide a comparison with Eurostar.
B.support the airlines’ optimism.
C.prove the inevitable drop of air passengers.
D.call for electrification and modernization of the railway.
19. The railway’s Brussels route is brought forth to show that__.
A.the Eurostar train service is not doing good business.
B.the airlines can well compete with the railway.
C.the Eurostar train service only caused little damage.
D.only some airlines, such as Air France, are suffering.
20. The passage is taken from the first of an essay, from which we may well predict that in the following part the author is going to__.
A.praise the airlines’ clear-mindedness.
B.warn the airlines of high-speed rail services.
C.propose a reduction of London/Paris flights.
D.advise the airlines to follow British Midland as their model.
