Passage 1Questions 26 to 30 are based on the following passage.For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological(生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.Papousek began his studies by using milk in the normal way to "reward" the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights-and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.According to the author, babies learn to do things which______.

Passage 2Questions 31 to 35 are based on the following passage. Every year 100 million holiday—makers are drawn to the Mediterranean. With one third of the world's tourist trade, it is the most popular of all the holiday destinations; it is also the most polluted.It has only 1 per cent of the world's sea surface, but carries more than half the oil and tar floating on the waters. Thousands of factories pour their poison into the Mediterranean, and almost every city, town andvillage on the coast sends its sewage, untreated, into the sea.The result is that the Mediterranean, which nurtured so many civilizations, is gravely ill—the first of the seas to fall victim to the abilities and attitudes that evolved around it. And the pollution does not merely keep back life of the sea—it threatens the people who inhabit and visit its shores. The mournful form of disease is caused by sewage. Eighty five per cent of the waste from the Mediterranean's 120 coastal cities is pushed out into the waters where their people and visitors bathe and fish. What is more, most cities just drop it in straight off the beach; rare indeed are the placeslike Cannes and Tel Aviv which pipe it even half a mile offshore.Not surprisingly, vast areas of the shallows are awash with bacteria and it doesn't take long for these to reach people. Professor William Brumfitt of the Royal Free Hospital once calculated that anyone who goes for a swim in the Mediterranean has a one in seven chance of getting some sort of disease. Other scientists say this is an overestimate; but almost all of them agree that bathers are at risk.Industry adds its own poisons. Factories cluster round the coastline, andeven the most modern rarely has proper wastetreatment plant. They do as much damage to the sea as sewage. But the good news is that the countries of the Mediterraneanhave been coming together to work out how to save their common sea.The causes of the Mediterranean’s pollution is ______.
Passage 1Questions 31 to 35 are based on the following passage: The economy of the United States after 1952 was the economy of a well-fed, almost fully employed people. Despite occasional alarms, the country escaped any postwar depression and lived in a state of boom. An economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them. Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s. As farmer’s share of their products declined, marketing costs rose. But there were, among the observers of the national economy, a few who were not as confident as the majority. Those few seemed to fear that the boom could not last and would eventually lead to the opposite---depression.What is the best title of the passage?()
