标题: 疑惑了。。请帮帮忙下，新prep1-202

Providing initial evidence that airport 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.

as much as that which is being emitted annually by all
as much annually as is emitted by the
as much compared to what is annually emitted by all
that emitted annually by all
that emitted annually compared to the

选的时候只想到twice+the+n，就选了D

可是发现这里that是作代词吗？不是this和that一般不能单独指代的吗？

请指教下啊！

顶下。。。有没有人帮忙解释下啊。。。

作者: sunny8843 时间: 2009-8-3 19:21
我觉得that指代the total amount of pollutant

THAT可以指同类的东西，就是楼上说的。IT就是具体指代了

哦。。。。是这样啊，我以前听xdf老师说that，this是不可以用来单独指代的，后面必须加名词。。。

以下是引用ccccccccccab在2009/8/9 19:58:00的发言：

哦。。。。是这样啊，我以前听xdf老师说that，this是不可以用来单独指代的，后面必须加名词。。。

那个应该是说that，this之类的词不能指代前面的整个句子，而不是单独的词。

这里that指代the amount。我选D。正确答案是啥？

作者: ccccccccccab 时间: 2009-8-11 08:56

哦。。是这样的啊。。。正确答案就是D

作者: snake37 时间: 2009-8-11 12:08
当然是D啦
A: which 前没有逗号，必错
B: 比较对象是amount，所以因该是twice as much as that emitted
C: as as
E: 语感完全错误，虽然我说不出具体的原因，但是这样的句子你一念就知道肯定错误，OG中把这种句子叫做wordy

觉得B项的错误是annually的位置错误，应该在emitted之后，这种主语的比较，that不必出来指代吧。
A也不是逗号的原因，而是整个句子都非常的不符合习惯，that和which都是指同一个东西，而being emitted这个时态也不好。

as much as that which is being emitted annually by all

as much annually as is emitted by the

as much compared to what is annually emitted by all

that emitted annually by all

that emitted annually compared to the

that在做比较的时候是优选的指代。这道题根据逻辑意思首先就排除了没有all的选项BD，接着看到C中的as后面没有as对应而是compare to，排除。A：that which is being 不简洁且表达的不是很清楚。因而优选C

作者: gmgmwll 时间: 2010-6-2 20:06
D项的emitted 的逻辑主语不应该是pollutant的吗？
这样的话，不就成了the amount vs pollutant了吗？
大家指教啊！！
还有这个比较的题总是做错，各位大侠要是有什么经验，能不能share 一下

B的正确表达应该是
the total amount of pollutant emitted annually by....is twice as much as that (is) emitted annually byu...

作者: sjtu_min 时间: 2010-8-13 01:17
我的看法：

D项的that指代的是the total amount of pollutant，补充完整后应该是这样的

... is twice (the total amount of pollutant) emitted annually by ...

这个句子是lz说得twice + the none结构。
