一题from manhattan

According to surveys by the National Institute on Drug Abuse, about 20 percent ofyoung 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.

From Ron:

if you're going to say COMMA + "twice as many as...", then that's incorrect unless there's actually a quantity in front of the comma.
e.g.
last year i read 40 books, twice as many as i read in the preceding year
--> correct
last year the number of books i read increased dramatically, twice as many as i read in the preceding year
--> incorrect

RON的意思是noun modifier必须就近修饰，和manhattan上讲的一致，这一题。。。凌乱了我，求指教

要注意后面的the number，稍微读下句子就自然的和前面的20 percent做对比，不会和其他的成分去对比的。

可是离这么远作noun modifier不会awkward么？

kiwifoodtown

比较对象清晰的情况下，间隔8个单词很远吗？
这里有一句比较结构的句子，我摘自《国富论》，你看看：
The corn of the rich country, therefore, will not always, in same degree of goodness, come cheaper to market than that of the poor.

这两个不是一回事吧，题目里的twice 是做修饰，摘自《国富论》是主句啊

没区别，比较结构，都为状语。

你说说看《国服论》那个哪儿做状语了

比较状语从句形式，比较连词后面部分（划线部分）为状语。

我全然晕倒。。。我不知道比较级than...属于状语，但确定的是它是固定用法和主语作比较，我不知道这两个例子是否属于一类，但是你老要传达的的：twice..可以距离主语很远来修饰 啊是啊？
