（3）以\"辅音字母＋y\"结尾的词, 先把y变为i,再加-er或-est。如：heavy—heavier——heaviest

shy — shyer —shyest （shy除外）

（4）重读闭音节词词尾只有一个辅音字母时，先双写这个辅音字母,再加-er或-est。如：big—bigger—biggest

（5）多音节词和部分双音节词,在原级前加more构成比较级,加 most构成最高级。如：beautiful

一more beautiful—most beautiful；famous—more famous-most famous 【拓展延伸】表示否定意义时,可在形容词或副词前加less / least。

tall — less tall — least tall important — less important——least important 二、不规则变化

三、比较级的用法。 1. 比较级 + than

用于两者之间的比较，表示“比……更……”。 如：Kevin is taller than me. George runs faster than I do.

【特别提醒】当than前后使用的动词相同时，通常用助动词代替than后的动词或省略后面的动词。

2. 比较级+ and + 比较级

该结构表示\"越来越……\当形容词或副词为部分双音节词或多首节词时,用\"more and more+形容词/副词原级\"表示。
