According to surveysby the National Institute on Drug Abuse, about 20 percent of young adults usedcocaine in 1979, doubling those reported in the 1977 survey. (A) doubling thosereported in the 1977 survey (B) to double thenumber the 1977 survey reported (C) twice those the 1977 survey reported (D) twice as much asthose reported in the 1977 survey (E)twice the number reported in the 1977 survey
我觉得这里的twice是做前置定语的,可是它修饰的20 percent中间还隔了个谓语,于是乎。。。。就觉得不正确,因为我在查看以前错题的时候有明确写着 前置定语,double as much as同位语修饰词,要紧接其修饰的内容,twice应该也是一样的吧,那这里怎么解释呢
其实这么来讲,你要是用词性来判断做题得累死,还有很多出其不意的惯用法,不清楚亲亲已经复习打什么程度了,但是对于twice的基本用法应该是有所掌握:a.twice as much/manyas sth.。 b.twice + n. 本体其实就是twice的第二种用法,twice+number可以直接使用
