单选题More American mothers than ever are working, and more workers are mothers. Yet their march into the world of paid work continues to cause suspicion. One recent survey found that 48 percent of Americans believe that preschoolers suffer if their mothers work, while another found that 42 percent of employed parents think that working mothers care more about succeeding at work than meeting their children's needs. All mothers deserve our support--those who care for children at home and those who have joined the work force. But many working mothers continue to believe that they are shortchanging (少找钱)their children. They shouldn't. Research tells us that kids do just fine when mothers work. Suzanne Bianchi a scientist of the University of Maryland, has found that mothers today spend as much if not more time with their children than they did in 1965, even though the percentage of mothers who work rose from 35 percent to 71 percent. Then there are the obvious financial benefits. For many children, these earnings are the difference between living in poverty—or out of it. The kids are all right. Studies conducted by the University of Michigan have consistently demonstrated that a child's social or academic competence does not depend on whether a mother is employed. In my research four out of five children (nine out of ten in single parent families) told me that having a working mother was their preferred arrangement. My study found that children with working mothers are no more likely to drop out, take drugs, break the law, or experiment with sex prematurely than children with non-employed mothers. Children have taken their mothers' example to heart. Ninety percent of the young women I interviewed said they hoped to combine work with motherhood, while two-thirds of the men said they wanted to share parenting and work. Sadly, children support working mothers more than we do as a society. Parental leave and child-care benefits in the United States remain inadequate, particularly when compared to what's offered in other countries. Children thrive when their mothers have satisfying, well-paid jobs when they can count on other caretakers to share the load. The challenge facing us is thus not whether good workers can also be good mothers, but whether we can create the conditions that enable working mothers and fathers to be good parents.

单选题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 successful male, a red symbol of courage in midlife. Six hundred thousand bypass 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 have it postponed. In Canada and Britain, where physicians perform bypass surgery much less frequently than they do in America,heart patients fare just as well. In addition, bypassing a blocked section of an artery does nothing to ;prevent the artery (动脉) from getting clogged somewhere else. In fact, bypass surgery can accelerate the development of new blockage. But bypass did not have to prove itself. It has become hugely popular. Voices of caution were drowned out as more and more hospitals raced to offer bypass. By 1979,100 000: bypasses a year were taking place, and 10 years later the figure has risen to 260 000. Medical students were keen to train in cardiac (心脏的) surgery; for all the hard training, it was a advancing ,challenging field. In fact, the rewards are handsome. There is more money to be made performing this surgery than there is in practicing in almost any other field of medicine. The idea of bold surgeons reaching into our bodies to save a wounded heart cannot but exert a powerful grip on our imaginations, as if we are witnessing a cultural ceremony where two overachieving individuals—surgeon and patient—come together, Bypass may indeed be both a life-extending and pain-relieving procedure for many patients. But perhaps it has transfixed us for too long.
