根据下面资料，回答题 Two-Layer System
Personality is to a large extent inherent. A-type parents usually bring about A-type 31 . Butthe environment must also have a 32 effect, since if competition is important to the parents, it islikely to become a major factor in the lives of their children.
One place where children soak up A-characteristics is school, which is, by its very nature, ahighly competitive institution. Too many schools 33 the" win at all costs" moral standard andmeasure their success by sporting 34. The current passion for making children compete againsttheir classmates or against the clock produces a two-layer system, in which competitive A-types seem
in some way better than their B-type fellows. Being too 35 to win can have dangerous consequences : remember that Pheidippides, the first marathon runner, dropped dead seconds after saying :"Rejoice, we conquer !"
By far the worst form of 36 in schools is the disproportionate emphasis on examinations. Themerits of competition by examination are somewhat questionable, but competition in the certainknowledge of 37 is positively harmful.
Obviously, it is neither practical nor 38 that all A youngsters change into B' s. The worldneeds types, and schools have an important duty to try to fit a child' s personality to his possible future employment. It is top management.
If the preoccupation of schools with 39 work was lessened, more time might be spent teaching children surer values. Perhaps selection for the caring professions, especially medicine, could bemade less by good grades in chemistry and more by such considerations as sensitivity and sympathy.It is surely a mistake to choose our doctors 40 from A-type stock. B's are important and shouldbe encouraged.
