both 的用法文档.doc

一、both用作代词，意为“两者”、“双方”。1.在句子中作主语或宾语，可单独使用或用于“both of.”结构中，但当of后面是名词时，名词前面必须有the、ones等限定词。另外，当其作主语时，谓语动词必须用复数。如：Both are good. 两个都挺好。Why not use both？ 为什么不两者都用？Both of them have gone out. 他们俩都外出了。Both of the men are asleep. 那两个男人都睡着了。Of course, I wish both of your children well. 当然，我祝福你的两个孩子都健康。2.用作主语的同位语。其位置主要有三种情况：放在实义（行为）动词之前；放在情态动词、助动词之后；放在连系动词be之后。如：We are both students. 我们俩都是学生。Dont thank me. You must both thank him! 别谢我。你们俩必须感谢他！ We have both passed the mid-examination. 我们俩都通过了期中考试。在简略回答及感叹句中，both不能位于句尾，要放在连系动词be、助动词或情态动词之前。如：Are you ready？你们准备好了吗？Yes, we both are. 是的，我们俩都准备好了（不能说Yes, we are both）。How clever they both are!他们俩多聪明啊！3.用作宾语同位语。这时，both要紧跟在宾语之后。如：You may take them both. 你可以把两个都拿去。He likes Tom and Wang Hai both. 汤姆和王海两个他都喜欢。二、both用作形容词，意为“两者的”、“双方的”。both作形容词用时，是一个首位限定词，它必须放在其他限定词或修饰词之前。如：There are lots of trees on both sides of the road. 公路两旁都有很多树。Please hold both my hands in yours. 请握住我的双手。Both children are my sons. 两个孩子都是我的儿子。both作形容词修饰复数名词时，意义上与either修饰单数名词是一样的。如：Both films are interesting. 两部电影都很有趣。Either film is interesting. 两部（中的任何一部）电影都很有趣。三、用作代词或形容词的both与not连用时，表示部分否定，意为“两者不都”。如：Both her sisters are not in Shanghai（=Not both her sisters are in Shanghai).她的两个妹妹并不都在上海。I wont take both, please. 两个我不全都要。Not both books are helpful. 两本书并不都是有益处的。四、“both.and”只用于肯定句，否定句要用“neither.nor”。如：Both you and I know this. 你和我都知道这事。Neither you nor I know this. 你和我都不知道这事。He can speak both English and French. 他既能讲英语，又能讲法语。He can speak neither English nor French.他既不会讲英语，也不会讲法语。1.
