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
答案为E
E中twice为adj.时,后面the number ...作何成分?
倍数+名词 是表达倍数的一个常用法。
可是突然发现twice 是副词,twice the number....副词能修饰名词???思想短路了。求教。
谢谢stoneren GG,又是你回答我的问题。
在that number is twice the number这个句子中,twice修饰谁呢? the number? 或者是修饰 is? twice是副词,好象不能修饰the number吧? 这就是我的困惑......因为twice +名词实在用得很多。
twice作为副词只能修饰动词或形容词,如果你注意的话会发现,在我们看到的绝大多数twice + n. 的结构中,这个短语本身都不是一个完整的句子,其实,这个短语绝大多数都是句子的简略;而twice作为标准句子的表达通常如下:Interest rates of our company are twice as high as those of our competitiors. 我们可以把这个句子改为:Interest rate of our company is 5%, twice as high as that of our competitors. 当然句子改的很不爽,但是可以区别出彼此的关系。
严重感谢stonere GG先.
我还是有问题:
从语法上讲,twice不能修饰名词,而从逻辑上讲,我觉得twice只能修饰名词the number呢.例如:Twice two is four.这里,twice修饰谁呢?修饰is吗?
再如GWD:
In
答案选B. but后是个完整句子, in 1929 almost twice that number of trucks alone came off the assembly lines. 这里twice又修饰谁呢? that number不是吗? 可是twice是副词,怎么能修饰that number 呢? 可是要理解成twice理解后面的came off好象很难呀......
还有就是这题大全51, twice the number reported in the 1977 survey.这里twice不是修饰the number吗?
心里很清楚 表倍数时 twice +名词 很常用.可对这个修饰就是无法理解.....stoneren GG再帮忙呀..... 无比感谢
看来只能这么理解了。反正就是记住:twice as many as/ twice +名词 两种固定表达。
非常感谢stoneren GG。每次都很细心认真地回答我的问题。谢谢你。
虽然答案选的是E 可是不明白C为什么错 不可以用those指代young adults吗
OG-4中的double也是这个用法, double的词性和twice一样吗? 都是adv 吗?
4. A survey by the National Council of Churches showed that in 1986 there were 20,736 female ministers, almost 9 percent of the nation's clergy, twice as much | ||
D 选: double the figure for 1977 |
