单选题 Compared with nonsmokers' children, the children whose parents both smoke are likely to ______.

A、 grow up more slowly
B、 be sick under the age of five
C、 develop lung cancer more often
D、 become smokers more easily

【正确答案】 C

【答案解析】

概括题。该题考点是归纳文章中的细节。文章第二段的第5至第6句为：“The children of smokers are more than twice as likely to develop lung cancer when they are adults as children of nonsmokers”。吸烟者的孩子得肺癌的可能性是不吸烟者孩子的两倍多。“The risk is even higher for children who live in homes where both parents smoke”。如果父母都吸烟，孩子患病的危险性就更大。归纳这些论述，可以断定答案为C)。
