问题     Opinion polls repeatedly tell us that the only thing Americans worry about more than the environment is their health. This is【C1】______understandable, for health is obviously【C2】______to illness. What makes today’s concern【C3】______health slightly surprising is that Americans are【C4】______healthier now than they have ever been. Many diseases that once【C5】______terror into hearts have either been completely【C6】______or brought under control. Although AIDS is a notable【C7】______， few new mass killers have come out to【C8】______the ones that have been eliminated.【C9】______. health — and the various threats to it — remains everyone’s【C10】______concern. After all, more than half of us (57 percent) will die from either heart disease or cancer, if current【C11】______continues.
    One major problem with any【C12】______of health risks — especially life-threatening ones — is that they【C13】______enormously in their immediacy. For instance, AIDS — if you get it — will probably be【C14】______after a number of years. Cancer induced by smoking or【C15】______to radiation, on the other hand, may take 20 to 30 years【C16】______its fatal effects show【C17】______. In making choices about health risks,【C18】______. it is important to bear in 【C19】______the likely time lag between taking a risk and【C20】______its consequences. [br] 【C17】
选项 A、off
B、out
C、up
D、over
答案 C
解析 语义衔接题。四个选项均可以与show搭配使用，但含义不同。show off“炫耀’：show out“送客”：show up“表露，显现”：show over“指引”。结合语境，这里应该是说癌症致命症状的显现，故答案为[C]up。
