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.
【C10】
选项 A、lasting
B、continual
C、continuous
D、durable
答案A
解析 语义衔接题。这里是说健康一直是人们所关注的，强调时间上从以往到现在的持续性，[A]lasting“持久的”强调时间上的持续时间很长，符合语义，故答案为[A]。[B]continual“不间断的”强调重复或持续发生，但连续之间允许有间断；[C]continuous“连续不断的”强调在时间和空间上没有间断；[D]durable“耐用的，持久的”强调物品的良好状态能保持很长时间。
