特殊用法
意为“越来越……”
(4) 比较级+and+比较级(单音节)

原级（多音节词和部分双音节词）
(5) the+比较级, the+比较级
意为“越……，就越……”

This film is as interesting as that one.
这部电影和那部电影一样有趣。
Jim does his homework as carefully as my sister.

He cannot run as fast as you.
他没你跑得快。
特别提醒：
not so/as.…as.… 结构通常可与比较级句式进行同义转换。
e.g. The filmis not so/as funny as that one.
这部电影没有那部搞笑。
That film is funnier than this one. 那部电影比这部搞笑。
grammar
as...as...表示平级比较
即时练习：Jane doesn't run as fast as Mary.（保持句意不变）
Mary runs _________ ________ Jane.
faster than
He works as hard as his brother.
He is as hard-working as anyone in his class.
★ 肯定句：A + as + 原级 + as + B A和B一样...
He works not so/as hard as his brother.
He is not so/as hard-working as anyone in his class.
★ 否定句式：A + not as/so + 原级 + as + B A不如B...
判断正误
She is as taller as her sister.
She is as tall as her sister.


中间的形容词或副词必须用原级。
As...as 结构 (A + as + 原级 + as + B)
联想拓展
① “as... as...”可以用来表示倍数。把twice、three times、half或
a quarter等表示倍数的词(短语)置于第一个as之前, 意为
“……是……的几倍/几分之几”。
She works three times as hard as me.
她用功的程度是我的三倍。
② as well as 是并列连词,意为“以及”,用来连接并列成分。当该
短语连接并列主语时，强调前面的主语,故谓语动词在人称
和数上与前一个主语保持一致。
The teacher as well as the students has read the book.
老师和学生们都读过这本书了。
