2.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 International Airport is twice as much as that which is being emitted annually by all motor vehicles in the Chicago meltropolitan 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    Y

E.that emitted annually compared to the

我选的是B,我觉得为什么是D类...

A…

B.to set dividends more conservatively than they have been.

C.to be more conservative than they have been in setting dividends   Y

我觉得A也没错啊...

A,as much as that which is being emitted annually by all（which is being 感觉多余）

B.as much annually as is emitted by the（annually位置不对，与之前的annually重复了）

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

D.that emitted annually by all   （twice+n that ——the total amount of pollutant 。

twice用法：twice as many/much as ,twice +the+n.,twice what 从句。我觉得这道题的选择印证了一句话：排除明显错误选项，选择尽量正确的，不一定是完美的）

E.that emitted annually compared to the（逻辑明显不对）

恩...有很多题目是选择best,所以会在两个选项里纠结....

谢谢你拉~
