否定句的常见形式和用法 中学英语表达否定含义的句式形式多样，用法灵活.准确地掌握与否定相关的语句形式和用法，有助于提高英语阅读理解的准确性.本文就中学英语中否定句的常见形式和用法总结如下： 一、常见否定句：否定副词not, seldom, never, hardly, rarely, nowhere等与谓语动词连用.例如： I'm afraid that I can not attend your party this weekend. 恐怕这个周末我不能参加你们的聚会.I can hardly understand what he said just now. 我不能理解他刚才所说的话. 注意：这些否定副词用于句首时，主句要使用倒装语序.例如： Seldom does he go to work late. 他很少上班迟到. Nowhere else can you find such a beautiful sunset. 你在别的地方不能见到如此美丽的日落. Never in my life have I heard such nonsense！ 我这辈子从来没有听过这种废话！ 二、否定祈使句：由“Don't 或Never+ 动词原形”所构成.例如： Don't give up trying even though it is difficult to learn English！ 英语虽然难学，但千万别放弃尝试！ Do not cut down the tree that gives you shade. 切勿忘恩负义. Never judge people by their appearance. 不可以貌取人. 三、全部否定：由“否定主语（否定代词或no+名词）+ 肯定谓语”所构成.例如： Nothing is difficult if you put your heart into it. 世上无难事，只怕有心人. None of us can speak French. 我们都不会讲法语. No man is born wise. 人非生而知之. 注意：常用“neither/nor + 助动词/情态动词 + 主语”来表达“某人也不……”.例如： Jim didn't know her secret, neither/nor did Jack. 吉姆不知道她的秘密，杰克也不知道. If you don't accept his invitation, neither shall I. 如果你不接受他的邀请，我也不接受. 四、否定转移：常见的否定转移有两种情况.1. 含有原因状语从句的主从复合句，形式上虽然否定主句的谓语，然而意义上则是否定该原因状语，译为“并不因为……而……”. 例如：Galileo was not ready to accept it just because Aristotle had said so.伽利略并不只是因为亚里斯多德说过某事如何如何，就轻易相信它.The mountain is not valuable because it is high. 山不在高.2. 当think, believe, suppose, expect, imagine等动词引导否定意义的宾语从句时，通常把从句中的not提前，把主句变成否定句，从句用肯定形式.例如：We don't believe that the news is true. 我们相信这个消息不是真的.I don't think that he is honest. 我认为他不诚实.注意：（1）把这些发生否定转移的句子变为反意疑问句时，疑问部分应与宾语从句主谓部分构成反意疑问句.例如：I don't think that he is honest, is he？ 我认为他不诚实.（2）not 常用在I think, I believe, I expect, I suppose, I guess, I'm afraid之后，构成省略句.例如：---Do you think it will be a fine day tomorrow? ---I'm afraid not. ---你认为明天天气会好吗？---恐怕不是.---Do you believe that Rocket will win the game? ---I believe not. (=I don't believe so.)---你相信火箭队会赢吗？---我看不会.五、否定疑问句：常用来表示反问、惊讶、建议、赞叹等语气.例如：Don't you know these traffic rules？ 难道你不知道这些交通规则吗？Aren't you supposed to be working？ 你不是应该正在干活吗？You look pale. Why don't you have a rest？ 你看起来脸色苍白，为什么不休息一会儿？Isn't it a lovely day？ 天气多好啊！注意：在回答否定疑问句时，要根据具体事实作答.例如：---Didn't you see the film Titanic yesterday? --- . I would like to have seen it. A. Yes, I did B. No, I didn't C. Yes, I didn't D. No, I did由于yes与肯定句连用，no与否定句连用，首先可排除C, D 两项.A, B 形式都正确，但从题目语境中最后一句话“我倒希望自己看了那部电影.”可知事实上我昨天没有看电影，故答案选B.如果把题干最后一句话改为“It's very moving.”，则说明我昨天看过电影，正确答案就应该选A.这种“根据事实作答”在运用中很不容易掌握，大家应该仔细体会其用法；同时，这种应答方法也适合于对“前否后肯型”反意疑问句和否定祈使句的回答.例如：---You haven't been to Beijing, have you?--- . And I visited the Summer Palace. A. Yes, I have B. Yes, I haven't C. No, I have D. No, I haven't 从答语提示可知事实上我去过北京，故答案选A.全句译为：“——你没有去过北京，是吗？——不，我去过.我还去参观过颐和园.”六、非谓语动词的否定式：通常把not或never放在非谓语动词to do, doing, p.p的前面.例如：I advised him not to smoke but he wouldn't listen. 我劝他别抽烟，可他不愿意听.Not having received a reply, she wrote him another letter. 由于没有收到他的回信，她又给他写了一封信.Not allowed to take part in the game, they felt very disappointed. 因为不让他们参加比赛，他们感到非常失望.七、双重否定句：由两个否定词搭配构成，表示一个较强的肯定语气.例如：Without air or water, man can not live on the earth. 没有空气和水，人类是无法在地球上生存的.Don't try to operate this machine unless you know the rules for safety. 如果不懂安全规则，千万别动这台机器。
