以下是引用dreadpower在2003-12-3 21:40:00的发言: 51.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 答案是E,请教 1。A,C,D中的those是否指代young adults?? 这里应该指代number,但是很显然是错的, 因为从错误分析看,是错指代了young adults
2。C选项改为twice the number the 1977 survey reported 对不对??和E比哪个好?
和E没有什么分别
3。如果不用twice the number 就用double来表述原句意思,可以吗?应该怎么表达(其他地方不改动,就改划线) 可以直接把twice 改为double,如果改成A里的,doubling the bumber......就可以了.double在这里做V.
