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 (C) twice those the 1977 survey reported (D) twice as much as those reported in the 1977 survey (E) twice the number reported in the 1977 survey OA:E。其中twice跳跃used cocaine修饰20 percent of young adults. 为什么A选项不对啊?在prep语法笔记上做了一道题是选择doubling的啊,这里又不选doubling了,真是混乱啊?!是因为young adults double。。。这样的主谓关系不搭吗?还是什么原因呢? |
