第二节 比较级
英语中形容词在开展较为时要变成比较级，关键有二种方式：
在词尾加-er (单音节形容词)，如：fast-faster, large-larger, busy-busier, big-bigger等；
或在词前加more (多音节形容词)，如：more useful, more complex等
极少数词比较级方式独特，如：good(well)-better, bad(ill)-worse, many(much)-more, little-less, far-farther(更长远的)/further(更进一步的)，
考试点一 含有标志词than
1．*普遍的比较级句型是由连词than正确引导较为的*，
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可视作比较级的标志词，在填空中，
空后含有than的， 一般空格处必须填比较级，
空格前含有比较级的，一般空格处必须填than正确引导的从句。
练习题：
(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
回答：A
表述：标志词than代表着运用比较级，A, B应先清除；D多the; 仅有A恰当
(2)
Pennsylvania has the most institutions of higher learning than any other state has.
应改成：more
表述：标志词than说明此句运用比较级，而不是*别
2．为防止反复，than以后的从句中一些成份能够省略，只把对比的一部分突显出去:
状况1: 用指示代词that, those来替代省略的一部分,
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)
状况2: 在省略的全过程中，若than以后从句的谓语一部分同样, 较为的是主语一部分, 那麼谓语一部分一般用助动词do来替代, 而且习惯性上把从句主语和助动词部分倒装 (do 主语)
如：The actors usually capture greater attention than do the playwrights who may
probably contribute more to the success of a play.
练习题：
Mammals have a larger, more well-developed brain ---- other animals.
(A) than do
(B) that are having
(C) which have
(D) that do
回答：A
表述：空格前出現了形容词比较级，空格后是较为*，应由than联接，选择项中仅有A满足条件，在其中由助动词do造成了一个小部分倒装
