Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat. When a manager gets a new sports car, a big house and pleasure boats dance into view. The needs of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of needs, another level appears. The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of housing, appears. By the end of World War II, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses. By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared: the “life-enriching” level. While the other levels involve physical satisfaction, this level stresses mental needs for achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing. On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels.【缺少答案,请补充】
There are two factors which determine an individual’s intelligence. The first is the sort of brain he is born with. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is the sort of environment in which he is brought up. If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never reach the level of intelligence of which he is capable. The importance of environment in determining an individual’s intelligence can be shown by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate homes. Peter was brought up by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark’s I.Q. was125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.【缺少答案,请补充】
Last week I visited one of my old neighborhoods in Washington D.C.. I had not been there for twenty years and as I walked along the street, my mind was flooded by memories of the past. I saw the old apartment building where I had lived and the playground where I had played. As I viewed these once unfamiliar surroundings, images of myself as a child there came to mind. However, what I saw and what I remembered were not the same. I sadly realized that the best memories are those left untouched. My old apartment building, as I remember, was bright and alive. It was more that just a place to live. It was a movie house, a space station, or whatever my young mind could imagine. I would steal away with my friends and play in the basement. This was always exciting because it was so cool and dark, and there were so many things there to hide among. There was a small river in the back of the building. We would go there to lie in the shade of trees and enjoy ourselves. However, what I saw was completely different. The apartment building was now in disrepair. What was once more than a place to live looked hardly worth living in; the windows were all broken. The once clean walls were covered with dirty marks. The river was hardly recognizable. The water was polluted and the trees and flowers were all dead. The once sweet smelling river now smelled terrible. It was really heart breaking to see all this. I do not regret having seen my old neighborhood. However, I do not think my innocent childhood memories can ever be the same. I suppose it is true when they say, “You can never go home again.”【缺少答案,请补充】
