语法小结:
1、 a.形容词和副词的比较级,表示两者(人和事物)的比较
b.在“比较级+than”的句型中,当than前后所使用的动词相
同时,通常用助动词代替后面的动词,该动词和助动词可以省略。
eg. a. Tina is more outgoing than Sam.
Who runs faster ,Lucy or Han Mei?
b. He works much harder than I (do).
He works much harder than me.
2、 形容词和副词的比较级前有时可以用much a little a lot far even等来修饰,例如:好得多much better a lot better 短一点 a little shorter
3、 表示两者在某一方面相同时用“as +形容词或副词原级+as”的句型
eg. I think science is as important as math.
Tom runs as fast as Jack.
表示一方在某一方面不及另一方面时用“not as /so +形容词或副词的原级+as”的句型,例如:It is not as warm today as yesterday. He did not come as early as Wang Lin.
形容词、副词比较级的构成:(1) 一般在形容词或副词后面直接加–er 变为比较级。
如:old—older high—higher
(2) 以重读闭音节结尾,且末尾只有一个辅音字母的,则双写最后一个辅音字母,再加-er变为比较级。
如:big—bigger thin—thinner
(3) 以“辅音字母+y”结尾的单词,则将改y为 i 再加-er变为比较级。
如:busy—busier heavy—heavier
(4) 以字母 e 结尾的单词,直接加 –r 变为比较级。
如:large—larger free—freer
2. 多音节以及某些双音节形容词或副词变为比较级时,则通常在其前加more变为比较级。
如:important—more important difficult—more difficult useful—more useful
3.不规则形式或易错形式:
much / many→more→most bad / badly / ill→worse→worst
far→farther / further→farthest / furthest little→less→least
few→fewer→fewest old→older / elder→oldest / eldest
