【课堂导学】

  1. Are you as friendly as your sister? 你和你妹妹一样友好吗?

同级比较的句型:“as+形容词或副词的原级+as”

as....as意为“和...一样”,结构为“as+形容词或副词的原级+as”,是同级比较的句式。第一个as是副词,含有“如此”之意,后跟形容词或副词的原级。第二个as是连词,表示“如同”的意思,引导的多是省略形式的比较状语从句,其中与主句相同的部分常被省去。

·This book is as interesting as that one(is).这本书与那本书一样有趣。

·You are                  your friend.你和你的朋友一样好

拓展as...as...的否定形式为“not (so)as+形容词或副词的原级+as”,意为“....不如....”,表示双方在某个方面不一样。

·Tom isn’t as/so tall as me.=I’m taller than Tom. 汤姆不如我高。

  1. Who is smarter, your mother or your father?谁更聪明,你的妈妈还是你的爸爸?

比较级句式:“特殊疑问词(Who/What/Which...)+谓语+比较级,A or B ?”

“特殊疑问词(Who/What/Which...)+谓语+比较级,A or B ?”用于两者作比较,表“两个中哪一个更.....”

·       runs faster, Tom      Kay? 谁跑的更快,汤姆还是凯?

·        skirt is more beautiful, the big one or the small one? 哪件裙子更漂亮,这件大的还是这件小的?
