The heart bypass (心脏搭桥术)has become part
of our cultural life. It has come to seem like a ceremony of passage for the

operations are performed a year in the United States. After a bypass, most heart
patients experience significant relief from the peculiar discomfort in the chest
caused by insufficient blood to the heart muscle. In some cases the surgery can
dramatically extend life. American heart patients, who now number about 12
million, are enthusiastic about the surgery. Bypass is one of the most common
major operations in America. In private, however, many of my fellow workers in medicine suspect that bypass has become too popular. A recent Harvard study showed that as many as two-thirds of patients referred for bypass don’t need it or could A. In a sense we may call the United States a "bypass nation". B. In Canada and the U.K. bypass operations are less performed because their medical levels are relatively lower. C. Bypass operations can solve the heart patients’ problems once and for all. D. Recent study shows that nearly all of the bypass operations in the United States are proved useless and needless. [单选题]高速铁路线路路堤坡脚、路堑坡顶或者铁路桥梁外侧起向外各()范围内禁止抽取地下水。

Choose the best example or explanation from the list A-F for each numbered subheading (41-45). There is one extra example which you do not need to use. Mark your answers on ANSWER SHEET 1. Although no longer slavers after the Civil War, American
blacks took no significant part in the life of white America except as servants
or laborers. Many thousands of them emigrated from the war-ravaged South to the
North from 1865 to 1915 in the hope of finding work in the big industrial
cities. Whole communities of blacks crowded together into ghettos in New York
City, Chicago and Detroit, where once the poor white immigrants had lived. These
ghettos, neglected by the city authorities, became slums. The schools to which
black children went were hopelessly inadequate. Unemployment in black ghettos
remained consistent
