大学英语四级考试阅读笔记(20)
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.

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.

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.

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
Every day, we grow and have new experiences. We constantly learn by reading, watching television, interacting with some people, and so forth. This learning affects our emotions. Why is it that we learn to like some people and dislike others? If a person is nice to us, cares about us, we learn to associate this person with positive feelings, such as joy, happiness, and friendliness. On the other hand, if a person is mean to us, does not care about us, and even deliberately does things to harm us, we learn to associate this person with negative feelings, such as unhappiness, discomfort, and anger.
注：1.interact 交往，相互影响
