标题: 求救,大全51,一个选项都排除不了!!!

1. According to surveys by the National Institute on Drug Abuse, about 20 percent of young adults used cocaine in 1979, doubling those reported in the 1977 survey.

(A) doubling those reported in the 1977 survey

(B) to double the number the 1977 survey reported

(D) twice as much as those reported in the 1977 survey

(E) twice the number reported in the 1977 survey

请问NN,这五个选项各错在哪儿,正确的应该是什么?

这里的those是不是错了?,但20 percent of young adults可不可以用those指代?

我觉得选E。

ACD的those指代不清，不能double young adults吧，又不是克隆。

B用不定式不对，这里double应该是修饰前面整个句子，只能用副词短语作状语（E选项）或者用分词短语表结果伴随。

大家继续讨论！
