大全test1-18

18.   There are far fewer children available for adoption than there are people who want to adopt. Two million couples are currently waiting to adopt, but in 1982, the last year for which figures exist, there were only some 50,000 adoptions.

Which of the following statements, if true, most strengthens the author’s claim that there are far fewer children available for adoption than there are people who want to adopt?

(A) The number of couples waiting to adopt has increased significantly in the last decade.

(B) The number of adoptions in the current year is greater than the number of adoptions in any preceding year.

(C) The number of adoptions in a year is approximately equal to the number of children available for adoption in that period.

(D) People who seek to adopt children often go through a long process of interviews and investigation by adoption agencies.（C）

(E) People who seek to adopt children generally make very good parents.

把C的论述运用到８２年的数据，就是说成功收养数和需要收养的儿童基本持平在50,000，而那一年愿意收养的夫妇达到两百万，因此是加强。

儿童数量是关键。反之，如果有选项说每年需要收养的儿童都至少有两百万，那就会削弱结论。

首句说结论: There are far fewer children available for adoption than there are people who want to adopt

说这里available adoption少于想要adopt的夫妇的数量.

后面的论证是用了这样一句话:there were only some 50,000 adoptions

要注意available adoption和adoptions之间的区别.

选项C就是一个架桥:available adoption = adoption

所以起到了加强作用
