Successful innovations have driven many older technologies to extinction and have resulted in higher productivity, greater consumption of energy, increased demand for raw materials, accelerated flow of materials through the economy and increased quantities of metals and other substances in use per person. The history of industrial development is full of examples. In 1870, horses and mules were the prime source of power on U.S. farms. One horse or mule was required to support four human beings—a ratio that remained almost constant for many decades. At that time, had a national commission been asked to forecast the horse and mule population for 1970, its answer probably would have depended on whether its consultants were of an economic turn of mind. Had they been “economists“, they would have recognized that the power of steam had already been harnessed to industry and to land and ocean transport. They would have recognized further that would be only a matter of time before steam would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.Which of the following is NOT mentioned by the author as a consequence of new technological developments? Older technologies die away. The quality of life is improved. Overall productivity increases. More raw materials become necessary.

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 continuously 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(动作的) 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.The main purpose of this passage is to ______. teach children how to learn to produce and experience certain emotions give the common reader a general description of two basic kinds of learning give parents some advice on how to modify their children’s emotions through learning discuss with psychologists how positive and negative feelings are produced
