2.形容词最高级
1) 当我们需要对三个或三个以上的人或事物进行比较，来表达最高、最远、最快等意义的时候，我们可以用形容词和副词的最高级形式来表达。
构成方法：
(1) 一般在词尾加-est.
(2) 以字母e结尾的形容词/副词，直接加-st.
(3) 以重读闭音节结尾的形容词/副词，应先双写该字母，再加-est. （注：常用的有五个big fat hot thin red,可以这样记：大胖子热瘦子是红色的）
(4) 多音节词和部分双音节词 在词前加most
注意：形容词的最高级前一般要加定冠词the, 而副词的最高级前则可加也可不加the。
5) 形容词（adj.）或副词（adv.) 的不规则变化：
many/much---- more----most
good/ well----better----best
little ---- less----least
bad/badly---- worse----worst
far---- farther----farthest（距离）
far---- further----furthest（抽象意义）
