例1:Western Nebraska generally receives less snow than ______ eastern Nebraska.
(A) does
(B) in
(C) it does in
(D) in it does
分析:than引導比較狀語從句,空格后面是個專有名詞,肯定是比較從句的主語,空格處明顯缺從句的謂語動詞,只有(A)符合條件,故選(A)。注意than eastern Nebraska does 是正確的語序,但是原文中使用了倒裝;在比較結(jié)構(gòu)的后面部分中,如果比較從句的主語長,謂語動詞短,動詞可放到主語前面進行到裝。
例2: Hot objects emit ______ do cold objects.
(A) rays more than infrared
(B) rays are more infrared than
(C) more than infrared rays
(D) more infrared rays than
分析:emit為及物動詞,空格處缺賓語和引導比較從句的than, 只有(D)符合條件。注意空格后為倒裝形式,do代替emit以避免重復。此題為?嫉木渥咏Y(jié)構(gòu)。
比較結(jié)構(gòu)中還需要注意相互比較的必須屬于同一種事物
例3:The activities of the international marketing researcher are frequently much broader than ______.
(A) the domestic marketer has
(B) the domestic marketer does
(C) those of the domestic marketer
(D) that which has the domestic marketer
分析:本題還是考查比較句,由于謂語動詞是系動詞are, 故先排除與其不對應的以has和does結(jié)尾的(A)和(B)。選項D則語義不清,也可排除。C中those代替前面提到的activities以避免重復,those一定要具備,因為只有這樣才能滿足比較的都是activities,謂語動詞are因與主句謂語動詞相同而被省略,因此C為正確答案。
例4:The annual worth of Utah's manufacturing is greater than ______.
(A) that of its mining and farming combined
(B) mining and farming combination
(C) that mining and farming combined
(D) of its combination mining and farming
分析:本題為比較句,一般來說,比較的雙方應屬于同一類事物。句中主語顯然是比較的一方,而空格處應是與之相對應的另一方。(B)、(C)、(D)均無法與the annual worth相對應,故可以排除。(A)中代詞that代替 the annual worth, 是英語中常見的避免重復的用法,故選(A)。
