倍数比较 twice是否可以直接加名词

坤kun

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．Correct；twice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！！

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？t ...

2022年了，找到了这个10年前讲倍数比较的帖子。简直救了命，respect

sorry 挖坟了~我的疑惑是，既然这里是numerical，应该直接用twice，那么twice as much as为何么没错呢？
举例的：twice as much as the increase...--> incorrect; redundant
谢谢！

楼主，我记得：
twice+n
twice+that
twice+what
twice as many/much as
都是对得
你背下来就好啦
