托??荚囕o導(dǎo):語(yǔ)法講解(12)

字號(hào):

第二節(jié) 比較級(jí)
    英文中形容詞在進(jìn)行比較時(shí)需變?yōu)楸容^級(jí),主要有兩種形式:
    在詞尾加-er (單音節(jié)形容詞),如:fast-faster, large-larger, busy-busier, big-bigger等;
    或在詞前加more (多音節(jié)形容詞),如:more useful, more complex等
    少數(shù)詞比較級(jí)形式特殊,如:good(well)-better, bad(ill)-worse, many(much)-more, little-less, far-farther(更遠(yuǎn)的)/further(更進(jìn)一步的),
    考點(diǎn)一 含有標(biāo)志詞than
    1.最常見的比較級(jí)句式是由連詞than引導(dǎo)比較的對(duì)象,
    如:It takes less time to go there by air than by train.
    She possesses more books than I do.
    He is more intelligent than I expected.
    than可視為比較級(jí)的標(biāo)志詞,在填空題中,
    空后含有than的, 通??崭裉幮枰畋容^級(jí),
    空格前含有比較級(jí)的,通常空格處需要填than引導(dǎo)的從句。
    例題:
    (1)
    Maine has ---- weather than most of the other states in the continental United States.
    (A) coolest
    (B) the coolest
    (C) cooler
    (D) the cooler
    答案:A
    解釋:標(biāo)志詞than意味著應(yīng)用比較級(jí),A, B可先排除;D多the; 只有A正確
    (2)
    Pennsylvania has the most institutions of higher learning than any other state has.
    應(yīng)改為:more
    解釋:標(biāo)志詞than表明此句應(yīng)用比較級(jí),而不是級(jí)
    2.為避免重復(fù),than之后的從句中有些成分可以省略,只把相比的部分突出出來(lái):
    情況1: 用指示代詞that, those來(lái)代替省略的部分,
    如:The population of China is much larger than that of Great Britain.
    (that 指代the population)
    His designs won more acclaim than those of his fellow colleagues.
    (those 指代 designs)
    情況2: 在省略的過程中,若than之后從句的謂語(yǔ)部分相同, 比較的是主語(yǔ)部分, 那么謂語(yǔ)部分通常用助動(dòng)詞do來(lái)代替, 并且習(xí)慣上將從句主語(yǔ)和助動(dòng)詞倒裝 (do + 主語(yǔ))
    如:The actors usually capture greater attention than do the playwrights who may
    probably contribute more to the success of a play.
    例題:
    Mammals have a larger, more well-developed brain ---- other animals.
    (A) than do
    (B) that are having
    (C) which have
    (D) that do
    答案:A
    解釋:空格前出現(xiàn)了形容詞比較級(jí),空格后是比較對(duì)象,應(yīng)由than連接,選項(xiàng)中只有A符合條件,其中由助動(dòng)詞do引起了一個(gè)小倒裝
