广西玉林市博白县宁潭镇第二初级中学

--刘欣琪

1. 比较级的用法:

1) 表示两者(人或事物)之间的比较

2) 常用于“比较级+than”句型中

3) 比较级前可用much,a little ,a bit(一点), a little bit(一点点),a lot(非常),even(甚至),far(非常),等修饰,不能用very。

My ruler is a bit__than yours.(A.long B.√longer)

Sam is__of the two. (A.friend B. √ friender )

Which do you like_. Tea or coffee?

A. good B. √better C. best D. well

Miss Brown’s hair is much longer than_.

A. me B.√mine=my hair C.I D.I am

(注意:必须是同类事物的比较,即人和人比,物和物比。所以是布朗女士的头发和我的头发比较)

“as+形容词/副词(原级)as…” 意为“和······一样”,属于原级比较。反义词组是:not as/so...as 不如······;比不上……

He is as tall as Tom. 他跟汤姆一样高。

She isn’t as outgoing as her sister. 她不如她的姐姐外向。

Lucy sang as__(loud) as Nancy.(答案:loudly。解析:首先,“as…as…”中间要用“形容词或副词原级”;那到底这里是用形容词原级还是副词原级呢?我们要考虑到“sang”是动词,要用副词来修饰,所以综合起来这里应该用副词原级)

She isn’t _good at tennis _her sister.

as; as B. as;for C. So;as D.√A and C
