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)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。

　　其否定式为not as/so +adj./ adv. +as。例如：

　　This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。

　　若有修饰成分，如twice, three times, 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。
