Questions 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 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.

　　注：1.past 和 widely accepted：老觀點(diǎn)和大眾觀點(diǎn)，一般應(yīng)該是否定的

　　2.used also to be widely：另一個(gè)老觀點(diǎn)

　　3.In other words 概括老觀點(diǎn)

　　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.

　　注：1.behave 行為，舉止 2.outcome 結(jié)果

　　3.with no reward except 雙重否定，所以是肯定結(jié)構(gòu)

　　4.本段闡述新觀點(diǎn)

　　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 childrens 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.
