Questions 16 to 20 are based on the following passage:
In these days of technological triumphs, it is well to remind ourselves from time to time that living mechanisms are often incomparably more efficient than their artificial imitations. There is no better illustration of this idea than the sonar (声纳) system of bats. It is billions of times more efficient and more sensitive than the radars and sonars designed by man.

3.incomparably 不可比地
4.第一句主题句：天然胜于人工 artificial 人工的5.illustration 例证，本段末句强烈结论
Of course, the bats have had some 50 million years of evolution to refine their sonar. Their physiological mechanisms for echo location, based on all this accumulated experience, therefore deserve our thorough study and analysis.

17. The author suggests that the sonar system of bats ____
A) was at the height of its perfection 50 million years ago
B) is better than man-made sonar because it has had 50 million years to be be refined
C) should have been discovered by man many years ago
D) is the same as it was 50 million years ago
注：B 选项体现一段结尾和二段开头，应该优选，含有关系词 because,although,not only...but also, as well as 的应该优选
To appreciate the precision of the bats' echo location, we must first consider the degree of their reliance upon it. Thanks to sonar, an insect-eating bat can get along perfectly well without eyesight. This was brilliantly demonstrated by the Italian naturalist Lazzaro Spallanzani. He caught some bats in a bell tower, blinded them and released them outdoors. Four of these blind bats were recaptured after they had found their ways back to the bell tower, and on examining their stomachs' contents, Spallanxani found that they had been able to capture and eat flying insects. We know from experiments that bats easily find insects in the dark of night, even when the insects make no sound that can be heard by human ears. A bat will catch hundreds of softbodied silent flying insects in a single hour. It will even detect and chase pebbles (卵石) tossed (向上扔）into the air.

Question 11 to 15 are based on the following passage:
In the same way that a child must be able to move his arms and legs before he can learn to walk, the child must physiologically be capable of producing and experiencing particular emotions before these emotions can be modified through learning. Psychologists have found that there are two basic processes by which learning takes place. One kind of learning is called "classical conditioning". This occurs when one event or stimulus is consistently paired with, or followed by, a reward or punishment, It is through classical conditioning that a child learns to associate his mother's face and voice with happiness and love, for he learns that this person provides food and comfort. Negative emotions are learned in a similar fashion.

2.modify 修改、改变；pair with 伴随
3.it is ...that 强调介词状语结构
●分类型文章：1.分为几类就是文章主题
2.抓住各类主体词/基本特征词（通常为动词）
3.多余段落通常例证某一类
The second kind of learning is called "operant conditioning." This occurs when an individual learns to do things that produce rewards in his environment and learns not to do things that produce punishments. For example, if a mother always attends to her baby when he cries and cuddles him until he is quiet, she may teach him that if he cries he will get attention from mother. Thus, the baby will learn to increase his crying in order to have his mother more.
注：1.operant 操作型的，词源 operate
2.cuddle 拥抱
3.第一种 classical conditioning：联系而去做；第二种 operant conditioning：有奖惩而去做
