as... as的用法总结 初中

　　使用该结构要注意比较对象的一致性，即比较的双方必须是可以比较的同类人或物，否则会出错。如：

　　你的房间与我的一样大。

　　正：Your room is as large as mine

　　误：Your room is as large as me.

　　涉及数量或程度

　　如果涉及数量或程度可用：as much+ (不可数名词+) as / as many+ (可数名词复数+) as。如：

　　You must speak English as much as possible. 你必须尽可能地多说英语。

　　You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。

　　注意下列结构的词序

　　她和她妈妈一样是位好厨师。

　　正：She is a cook as good as her mother.

　　正：She is as good a cook as her mother.

　　误：She is as a good cook as her mother.(www.yygrammar.com)

　　关于修饰语

　　修饰as…as结构的常见词语有nearly, almost, just, exactly, half, quite, twice, three times等，请注意这些修饰语都只能放在as…as 结构之前 (而不能置于其中或其后。如：

　　I earn half as much as you do. 我只赚你的一半钱。

　　This rope is twice as long as that one. 这根绳子比那根长一倍。

　　省略用法

　　as…as结构在一定的上下文中可以用其省略结构(即省去其中的一个 as)。如：

　　She’s clever, but her brother is just as clever. 她很聪明，但她兄弟也一样聪明。

　　The woman married a man poor as herself. 这个女人嫁给了一个与她一样穷的男人。
