4、+ 名词 + as ”构成。as.as 意为“和一样“，表示同级的比较。使用时要注意第一个 as 为副词，第二个 as 为连词。其基本结构为： as+ adj./ adv. +as。例如： (1)This film is as interesting as that one.这部电影和那部电影一样有趣。 (2) This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。Luckily the weather was not so wet as it is today.若有修饰成分，如 twice, three times,
5、half, a quarter 等，则须置于第一个 as 之前。例如：Your bag is twice as expensive as mine.你的袋子比我的贵一倍。（二）. “否定 + 比较级” 相当于最高级。 Wait until we get a satisfactory reply, will you? I couldnt agree more.
