英语知识点：比较级与最高级的用法

(1) as 形容词或副词原级 (as…)
1. 在肯定句中用as…as…，在否定句或疑问句中可用not so…as…或not as…as…。如：he cannot run so/as fast as you.

he is (much) cleverer than his brother.（对）
2. 要避免将主语包含在比较对象中(当比较主体与所属群体中其他主体进行比较时，要用“any other 单数名词”或“all the other 复数名词”，以把自己排除在外)。如：
china is larger than any country in asia.（错）
china is larger than any other country in asia.（对）
(3) 可修饰比较级的词：much, even, far, still, a lot, lots, a great deal, a bit, a little, by far, any, yet, all the等。

(5) “比较级 and 比较级(-er and -er或more and more adj./adv.)”。如：the girl becomes more and more beautiful. / it is becoming warmer and warmer.
(6) “the 比较级”意为“两者中较为…的那一者”。如：i took the smaller one.
(7) 比较级表示最高级含义
1. “否定 比较级”。如：nothing is more valuable than time. / i have never seen a better one．
2. “比较级 than any other 可数名词单数”。如：the changjiang river is longer than any other river in china．
(8) “less 原级 than”表示“表示一方不及另一方”。如：this room is less beautiful than that one.
(9) 某些以–or结尾的形容词进行比较时，与to搭配使用，而不是than。这些词有inferior, superior, junior, senior, prior等。如：he is superior to mr wang in mathematics.
二、最高级的用法
(1) 三者或三者以上相比，表示最高程度时，用“the 最高级”的结构表示。这种句式常有表示比较范围的介词短语。如：zhang hua is the tallest of the three.
(2) 最高级可被序数词以及by far, nearly, almost, by no means, not quite, not really, nothing like等词语所修饰。如：this hat is nearly / almost / nothing like the biggest.
(3) 作状语的副词最高级前可以不加定冠词。如：of all the boys he came (the) earliest.
