在新prep语法比较的15页有这样一段话:
1.关于twice as many/much as结构:

(http://www.manhattangmat.com/forums/the-number-of-people-flying-first-t5600.html)

(3)If the noun in question is already anexplicitly numerical quantity, then you should useneither"much" nor "many". Instead, you should just use "twice" or "double" by itself.
e.g.,twice the increase--> "increase" is an explicitly numerical quantity

(4)These rules are followed pretty closely.
so, for instance:
twice as much water--> correct, since "water" is an uncountable noun (but is not an explicitly numerical quantity)
twice the water...--> incorrect, since water is not a numerical quantity
twice as much as the increase...--> incorrect; redundant
twice the increase...--> correct
我理解的意思是,twice如果直接加名词就只能加那些本身已经表示数值的词,

但是,prep08 sc1 202题
Providing initial evidence that airports are a larger source of pollution than they were once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O’Hare International Airport is twice as much as that which is being emitted annually by all motor vehicles in the Chicago
metropolitan area.

A.as much as that which is being emitted annually by all

B.as much annually as is emitted by the

C.as much compared to what is annually emitted by all

D.that emitted annually by all
E.that emitted annually compared to the



答案选D,解释中有一句话:

D.Correcttwice后面可以直接接名词,twice as much as也是对的
所以我就confused了,到底twice后面能不能直接加名词啊??!
求问各位大牛,拜谢!!

俺不是大牛,但是我记得看过大牛的帖子,twice 可以作为前置词predeter,可以直接加名词。
例如:twice the amounts
(具体的还是等等大N吧)

嗯,我觉得这个问题是这样的:
twice可以做形容词,也可以做副词
我们先看例句吧
例句中的所比较的是什么呢?
the amount of pollutant ... is twice that ....
这里twice是做形容词使用

首先,我们知道,在对数字进行倍数的直接比较的时候,twice是做形容词使用的:
[e.g.1]The cost of a ticket is $12, 6 times the cost ten years ago. (比较对象是具体的数字)
[e.g.2]The concert was attended by 300 people, twice the previous attendance.

在明白上面的例子后,就产生一个问题,为什么lz给的例句里,twice可以做形容词使用呢?

我们先看下面一组句子:
[e.g.3]The length of a rectangle is [twice] its width. 形容词
[e.g.4]The rectangle is [twice] as much in length as in width. 副词

首先,我们知道rectangle有多种属性,比如长,宽,面积,形状之类的
那当用The length of a rectangle这个短语后,那比较的对象的属性就确定了,那衡量这个属性的“量”也就确定了,所以在对“the length of a rectangle”进行比较的时候,就相当于是对“量”进行比较;并且“the length of a rectangle”在句子中做主语,所以可以用twice做形容词。这时[e.g.3]中twice的使用方法,就跟[e.g.1]和[e.g.2]的相同。

其次,为什么[e.g.4]中不存在twice做形容词的使用方法呢?
因为[e.g.4]中的主语不是一个具体的“量”,而是一个“物体”,这个物体可以有各种各样的量,比如长,宽,高,面积,等等;而此时,twice就不能做形容词,因为根据主语,我们无法判断比较前后的“量”到底是什么。所以必须用twice as much + in length as

这样,我们回过头来看lz的例句,就能明白,为什么这里可以使用twice做形容词了。因为句子的主语是the amount of pollutant,pollutant可能有很多属性颜色啊,气味啊之类的,但是在这句话里,已经可以等价成一个具体的“量”了,所以可以用twice做形容词。

just my 2 cents, 欢迎大家讨论

NN, 那请问D给的解释中说用twice as much as也可以,不是说要是比较量化的数字,如number,就不能用twice as much as, 要用as great as  么
