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 ture. But it used also to be widely believed that effective rewards, at least in the early time, had to be directly connected to such basic physiological “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 success in sight.
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 (回答) 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 “turned on” some lights-and indeed that they were able to learn some more turns to bring about this result, for example, two left or two right, or even to make as many as three turns to one side.
Papousek's light experiment was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the light closely although they would “smile and speak” when the light was on. Papousek concluded that it was not the sight of the lights which pleased them. It was the success they were achieving in solving the problem, in mastering the skill, and then there is a basic human nature to make sense of the world and bring it under control.

In the 1940s, Pinehaven Park was one of Crafton City's loveliest recreation(娱乐)areas. Over 40 acres of woods and fields were open to the public. In the 1950s, part of the park was taken over by Crafton City's garbage. Fifteen acres were to be used for landfill disposal(理置). As time went on, more and more of the park was used for garage disposal and less for recreation. Two years ago, the park was closed to the public for good. Along with household garbage, industrial chemicals had for years been dumped (倾倒)in the Pinehaven landfill. These poisonous chemicals had begun to seep(渗)back up through the soil. All of Pinehaven Park had become dangerously polluted.
Last year, the fish in the Crafton River began to die. After a series of investigations(研究), it became clear that the people of Crafton City were not to blame. 100~150 miles upstream, big paper mills were dumping industrial wastes into the river. Little by little, the level of poison in the river began to rise. Finally, it became so polluted that the fish themselves could no longer survive.
Downtown Crafton used to be a quiet area. Ten years of remarkable growth changed that in a big hurry. But with Crafton City's new prosperity(繁荣)came a new problem: air pollution. And it is a serious problem. Air pollution levels in Crafton are regularly reaching those of the nation's large industrial cities.

[ ]
A.Chemical dumping is a serious threat to Crafton City's soil.
B.The rapid growth of industry has brought air pollution to Crafton City.

D.Industrial growth and progress have resulted in the pollution of Crafton City's water, air, and soil.
(2)According to the passage, what portion of the park had originally been marked for use as a garbage dump?
[ ]
A.Less than half B.Exactly half
C.About one third D.Most of it
(3)As it is used in the passage, the phrase“for good”means ________.
[ ]
A.practically B.for ever
C.thoroughly D.advantageously
(4)According to the passage, one result of dumping industrial chemicals into the landfill was that ________.
[ ]
A.the land became unsafe for humans
