英語專四??颊Z法知識點(diǎn)(9)

字號:


    九、比較結(jié)構(gòu)
    比較結(jié)構(gòu)中要注意兩點(diǎn):1、倒裝性;2、對稱性
    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(dǎo)比較狀語從句,空格后面是個(gè)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(dòng)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(dòng)詞短,動(dòng)詞可放到主語前面進(jìn)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(dòng)詞,空格處缺賓語和引導(dǎo)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(fù)。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
    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(dòng)詞是系動(dòng)詞are, 故先排除與其不對應(yīng)的以has和does結(jié)尾的(A)和(B)。選項(xiàng)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(fù),those一定要具備,因?yàn)橹挥羞@樣才能滿足比較的都是activities,謂語動(dòng)詞are因與主句謂語動(dòng)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(yīng)屬于同一類事物。句中主語顯然是比較的一方,而空格處應(yīng)是與之相對應(yīng)的另一方。(B)、(C)、(D)均無法與the annual worth相對應(yīng),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(fù)的用法,故選(A)。
