是不是twice前面少了be动词啊,如果doubling的话前面就不需要加。。。
呵呵,我感觉是这样

动词>名词?

应该是twice as much as

为什么是as much as呢?

是否因为increase不可数????

n this case, you can't use "..., twice as many as...", because that's an appositive modifier. appositives must modify some noun that comes IMMEDIATELY before the comma, which in this case would have to be whatever figure is twice whatever other figure. since no such figure is given, you can't use this construction.

so, A, B or C

by contrast, the -ING FOLLOWED BY A COMMA modifies the entire action of the preceding clause. this is exactly what you want to happen, because the actual rising of the # of people flying first class is what "doubled the increase of...". there's no noun in there that pinpoints this concept, so you have to use a modifier that modifies the entire clause.

问了很久没人回答的易混语法题!版主!版主来看看呀!虽然题目长了点!万分感谢

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 大多数网友给出的解释是 those在这里指代的是人.double和twice后面都应该跟数字,这道题我的疑问是E选项中的句子在整个句子中做什么成分? 状语? 同位语? 独立主格?
再看第二道
The number of people flying first class on domestic flights rose sharply in 1990, doubling the increase of the the previous year.

A.
B. doubling that of the increase in
C. double as much as the increase of
D twice as many as the increase in
E. twice as many as the increase of
答案是A  我知道DE选项有一个错误就是many应该为much,increase是不可数的,但如果many 改成much ,E对不对?还有double 和twice 后面不是应该跟数字(number),跟increase也可以吗?
第二道题 在Manhattan Gmat forum 中 一位staff 给出这样的解释"in this case, you can't use "..., twice as many as...", because that's an appositive modifier. appositives must modify some noun that comes IMMEDIATELY before the comma, which in this case would have to be whatever figure is twice whatever other figure. since no such figure is given, you can't use this construction. "  后面他又给出解释"if you want, you can just memorize this an idiom, but "twice Y" / "X times Y" can definitely be used as an appositive."

他给出的解释我存在疑问, 他的意思是说twice as ... as , twice  y, must modify some noun that comes IMMEDIATELY before the comma,依据他的解释判断第一道题
,答案就不是E了? 因为逗号前没有具体名词!
请大家帮帮忙! 给说说 twice 和double 有没有区别?

是不是可以这样理解:
在第一题中, about 20 percent of young adults used cocaine in 1979, doubling those reported in the 1977 survey. 主语是 20 percent of young adults ,是一个明确的数字,而题目原意也正是这个数字 twice as much as those reported in the 1977 survey.

而在第二题里,是The number ... rose sharply 整个这件事 doubling the increase of the the previous year. 所以用的修饰方式不同。

prep语法里说2.    注意doubling the increase of 和 double as much as the increase of是两个完全不同的结构
我想知道double as much as the increase of是个什么结构?正确么?

(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

我觉得是因为 double应该是用来指young adults的数量增加了,只用一个doubling those有指代不详语义不清的嫌疑。而E用了number整个句子的意义就清楚了。

顶顶啊  表示不懂啊~!

这道题答案是E.  A is wrong because of "doubling those," which in this sentence refers to nothing. The author intends for it to refer to young adults, but it could only refer to percent as it stands.  B, to double 错误, C也和A一样,D不可以说 twice as much as the men….(要用many)          If the noun in question is already an explicitly numerical quantity, then you should use neither "much" nor "many". Instead, you should just use "twice" or "double" by itself.  e.g., twice the increase --> "increase" is an explicitly numerical quantity
