比如說：
他比Jim高。
這條河流比那條河流長。
這本書比那本重。
He is taller than Jim.（比較級的時候，就不能用原形了。）
（tall-taller；long-longer；heavy-heavier）

比如說：

這個房子是所有的房子中最大的一個。
（tall-tallest；big-biggest）
你知道比較級和最高級是如何構(gòu)成的嗎？
必須要知道！
第一種情況：如圖所示：
?
第二種情況：部分雙音節(jié)與多音節(jié)的詞比較級在原級之前加more, 最高級在原級之前加most
beautiful---more beautiful---most beautiful
interesting---
difficult---
第三種情況：不規(guī)則變化的形容詞:
little （原形） - less （比較級）- least（最高級）
good/well（原形） - better（比較級） - best（最高級）
bad/ill （原形） - worse（比較級） - worst（最高級）
far （原形）-- further—furthest
many/much——more——most
few——fewer——fewest

A as+形容詞或者副詞原形+as B 這是原級比較，
Bob is taller than John.
