1.原级(同级)比较:as…as…; not as(so)…as…

english is as interesting as chinese.英文和中文一样有趣。

you’re a boy as good as tom.=you’re as good a boy as tom. 你和汤姆是一样好的孩子。

比较级:(1)两个人或事物的比较。

主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。

否定用not+比较级+than或less than

2)表示两者之间比…… 更……可用状语 a little,a bit,a lot,a great deal , much,even,still,far,rather,any等修饰:

3)表示两者之间进行选择“哪一个更。时,用句型“which/who is +形容词的比较级,a or b? ”表示。

4) 如果在两者之间表示“最……”时要在比较级前加the,而且还用of the two, of the pair短语:

john is the clever of the two boys.

of the two boys, john is the clever.

5)表示“越来越。用比较级重叠结构,即“比较级+and+比较级”,当形容词为多音节词或部分双音节词时,用“more and more +形容词原级。”

it’s getting warmer and warmer in spring.

6)表示“越。越。时,用“the +比较级,the +比较级”。

重点词汇讲解。

1. both+名词复数形式,后面的谓语动词用复数形式:both my parents are doctors.

both of后接名和代,名词前要加the或形容词性物主代词:both of us like paragliding.

both…and… 既…又…,…和…都;连接两个并列成分,谓语动词动词用复数。

both mary and i sing well.

2. make make sb. do sth.=let sb. do sth.让某人做某事 don’t make me laugh.

make+宾语+adj.(形)使宾语怎么样:the story made us happy.
