之前我們從比較對象標(biāo)準(zhǔn)，比較詞判斷，和比較對象的判斷的三個方面分析了比較題。為了保證大家能夠徹底掌握，我們今天再看一個相應(yīng)的例題。
接下來的例題，我們依然按照統(tǒng)一的比較題解題步驟講解：
1：根據(jù)比較詞判斷比較考點
2：判斷比較詞對不對
3：判斷比較對象是否正確
例一：
Providing initial evidence that airports are a larger source of pollutionthan they were once believed to be, environmentalists in Chicago report thatthe total amount of pollutant emitted annually by vehicles at O’HareInternational 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 emittedannually compared to the
1 根據(jù)劃線部分as much as判斷此題考查比較考點。
2 判斷比較詞是否正確。
當(dāng)compare to一起出現(xiàn)時，它不表示比較的意思，所以我們知道CD選項的比較詞錯誤。
3 判斷比較對象是否正確
補充知識：
1 根據(jù)比較題目的第二講，我們知道A as…as B句型里面比較的是A和B，也就是兩個as前后的內(nèi)容。
2 AD 選項都出現(xiàn)that，我們先來補充一下它的用法。That通常作用引導(dǎo)定語從句的連接詞，但是在比較句里面，它是代詞，指代比較前面出現(xiàn)的相同的信息。
舉例：
The shoes of men and women
這個表達有一些歧義，因為這里有兩種可能的并列：鞋子和鞋子并列以及男人和女人并列。因為不同的并列就代表不同的意思，所以這里顯然是有歧義的。
改正：
1 鞋子和鞋子并列
The shoes of men and shoes of women 進化為The shoes of men and those of women
用that指代前面出現(xiàn)的單數(shù)名詞，用thoes指代前面出現(xiàn)的復(fù)數(shù)名詞
2 男人和女人并列
The shoes of both men and women
A 選項比較的是the total amount of pollutant emitted annually by vehicles at O’Hare
International Airport is…句子和that which
is being emitted annually by all…。That指代前面的the total amount，所以前面是句子和后面的一個名詞無法比較。排除
B 選項比較的是the total amount of
pollutantemitted annually by vehicles at O’HareInternational Airport is…和the total
amount is emitted by all 污染物總量有多少和污染物總量是由誰釋放的這兩件事情無法比較。排除
D 選項the total amount of pollutant emitted annually by vehicles at O’Hare
International Airport is…和the total amount of pollutant emitted annually by前后比較的分別是由O’Hare International Airport釋放的污染物總量和由所有汽車釋放的污染物的總量，顯然兩者可以比較
正確答案：D
S
