Manhattan Cat题库中的一题，关于double的用法，没有见人讨论过

Macklemost

[size=12.0012px]According to the National Science Foundation, in 2003 there were 198,113 female science and engineering graduate students, almost 42% of the graduate students in those fields, twice as much as 1981.

[size=12.0012px]

		twice as much as 1981
		twice as many as 1981
		double the figure for 1981
		double what it was in 1981
		a number double that of 1981’s

In the original sentence, “much” incorrectly references the quantity of female graduate students. Students are countable, so “many” is the correct term. Additionally, “as 1981” incorrectly completes the comparison, illogically comparing the number of people (the “198,113 female science and engineering graduate students”) to a year (“1981”).

(A) This choice is incorrect as it repeats the original sentence.

(B) “As 1981” incorrectly completes the comparison, illogically comparing the number of people (the “198,113 female science and engineering graduate students”) to a year (“1981”).

(C) CORRECT. “Double the figure” places the emphasis on the number of female graduate students, and correctly completes the comparison between the number of people in one year (198,133 in 2003) and the number of people in another year (the figure for 1981).

(D) “What it was” is wordy, awkward, and unclear.  The singular pronoun "it" has no clear antecedent.

(E) “Double that of 1981’s” is wordy, awkward, and unclear. The singular pronoun "that" has no clear antecedent. The possessive "1981's" is not followed by a noun to possess.

我想问，这里的double是不是不作动词，而做名词，就跟twice the+Noun一个性质呢？

double可以作名词吗？

double 是可以做名词，但是在这里做的却不是名词，个人的想法是这里的用法和 twice the figure for 1981 是一样。楼主如果有买manhattan 的SC 可以去论坛向RON直接提问的。得到答案后，要来和大家分享哦。

这里考的是一个比较平级的问题：数字是不能和年比较的所以AB肯定已经是不对的了。 修饰是要遵循就近原则的，这里在划线部分前表述的是percentage 肯定是不能用many 这种修饰可数名词的来修饰所以B 又多一条不对的地方。

最后做这题有个捷径，前面出现过数字又出现过百分比的时候，一般选项里都会有the figure 这种广泛性的表达存在。这种捷径当然只能在是在是吃不准选项的情况下使用，基础还是重要的。

楼主可以将 PREP 和 OG中 double / twice 的题目总结归纳一下。

我是一眼就看出来数字和年不能平行，但又觉得其他都不对

中间almost的那个是插入语不看，然后整个句子变成：according to..., there were 198113 students double the figure ...吗？ 感觉不太通呀

插入语是用来补充说明前面的意思的 其实意思是相同的，所以才会在一般的情况下读句意时可以略去不看。

当插入语后面有修饰的时候，就像我上面说的，修饰手法就就近原则的 所以这里double the figure 这里修饰的时42% of  the graduate students in those fields.

楼主要明白，论坛里说的插入语略去不看不是真的不用看 而是在理解句意的时候可以略去不看。

那这样double就应该改成ing形式的participial modifier才能修饰名词呀。我纠结的是动词double怎么能做修饰语呢。

在manhattan prep上问了，可是还没有专家回复，我自己想了一下

我觉得double应该作名词用，做同位语修饰。比如cat里面这句话，double也是做名词：

This past season, the number of flagrant fouls was double the number from the season

求CAT里的原文解释。

我理解无能 不能理解为什么这里double 是做名词的。 如果是 double number 那我还能理解这里double 是名词

请赐教

好巧，我做到了，也错了，寻求SC比较的整理文档

多谢层主贴出解释，楼主已经贴出了解释了。我和楼主在讨论double 的词性。楼主举例子说CAT有另外一个例子（层主网上看）说是做名词。我理解无能怎么会做名词，所以希望楼主将另外一个例子的解释贴出来，而不是这一题。

关于原题其实是不难的就是比较的对象不平级。female graduate students 不能和1981 比 所以AB是不对的
