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(jiàn)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?zhuān)簶?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?zhuān)簶?biāo)志詞than表明此句應(yīng)用比較級(jí),而不是最高級(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(guò)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?zhuān)嚎崭袂俺霈F(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
