形容词的级别
英语中形容词通常有三种等级 — 原级、比较级和最高级，用来描述人或事物在某个方面的不同程度。其中比较级的构成分为规则变化（分为长词变化规则和短词变化规则两类）以及不规则变化。

形容词的比较级和最高级
1. 当我们将两个对象进行比较时，我们要用形容词的比较级，表示“较……”，“更……一些”，“比……更……”。如：
My cousin is taller than I am. 我的表哥比我高。
2. 当被比较的对象是三个或三个以上时，我们会用形容词的最高级，表示“最……”，最高级前通常要加定冠词the。如：
This is the most interesting story in the book.
这是这本书里最有趣的故事。
注意：被比较的对象可以是人，也可以是事物。

注意：构成形容词比较级和最高级的er和est，自成一个音节，读作[ ]和[ st]。如果原级词末为不发音的字母r，加er和est时，r要发[r]音，如clear、clearer、clearest。如果原级词末的发音为[ ]，加er和est时，[ ]音后得加上[ɡ]音，如long、longer、longest。
