请问英语宾语从句中否定前移是怎么回事
根据语法的惯例,think,suppose,believe,imagine,guess 等后的宾语从句如果是否定句,要把否定转移到主句的think等动词上,这叫做“否定前移”或“否定前置”.
如:I think you can not go there by bus.(误)
I don’t think you can go there by bus.(正)
我认为你不能乘坐公共汽车去那儿.
在冀教版九年级课本第25课课文中,有这么一句话:“I thought you didn’t have any money.”该句是一个宾语从句,从句中的否定没有转移到主句中.这是为什么呢?是不是还有其他情况下否定不前移呢?笔者经过翻阅若干本英语参考书及工具书,总结出以下情况下think 等词后的宾语从句的否定不能转移到主句think动词上.
① think 是完成时态或完成进行时态时;
如:I have been thinking that we should not take his advice.
我一直认为我们不应该听他的话.
② think 是一般过去时或过去进行时态时;
如:We thought that this book was not worth reading.
我们认为这本书值得一读.
③ think 前有副词修饰的时候;
如:I almost think you are not my son’s teacher.
我差点认为你不是我儿子的老师.
④ think 前有do,did 等词强调时;
如:I do think that she is not pretty at all.
我确实认为她不漂亮.
⑤ think 用于一般疑问句或特殊疑问句中;
如:Do you think he will not join the Party?
你认为他不会入党吗?
Why do think we can’t beat you?
你们怎么认为我们打不赢你们呢?
⑥ 当think后的宾语从句中含有no,never,nothing,nobody等否定词时;
如:I think she may have nothing to do today.
我认为她今天没事干.
⑦ 当 think 用作插入语时;
如:Your sister ,I think,is not a friendly gay.
我认为你妹妹不太友好.
⑧ 当think后的宾语从句中含有not at all,not a little,not enough,can’t help doing 等固定词组时;如:I think you can’t help laughing when you hear the joke.
我认为你听到这个笑话时会忍不住笑的.
⑨ 当think和另一个动词构成并列谓语时;
如:I think and hope you won’t feel sad even if you lose the match.
我们认为也希望,即使您们输掉了比赛,你们也不会伤心的.
⑩ 当think用作虚拟语气的谓语had thought,表示“本来认为……”时;
如:I had thought that he hadn’t come here.
我本来认为他不来了呢.

1.not+think,believe,suppose,imagine…+that-clause(that 从句)   在这种句式中,not从宾语从句的谓语动词的前面,转移到了主句谓语动词think,believe,suppose等的前面。即(否定前移)例如:   e.g.:I'm sorry,but I don't think I know you.对不起,我想我并不认识你。   e.g.:I ...

1.not+think,believe,suppose,imagine…+that-clause(that 从句)   在这种句式中,not从宾语从句的谓语动词的前面,转移到了主句谓语动词think,believe,suppose等的前面。即(否定前移)例如:   e.g.:I'm sorry,but I don't think I know you.对不起,我想我并不认识你。   e.g.:I don't believe he'll come.我想他是不会来的。   这类句子后面的反意疑问句更能准确地说明not的否定范围。如:   I don't think you've met Xiao Xin,have you?我想你没遇见小新,对吗?   在初中范畴,做这类否定转移的反义疑问句的窍门:   例句:I don't think you've met Xiao Xin(改成反义疑问句)   步骤1:将否定转移掉,原句变为:I think you haven't met Xiao Xin.   步骤2:把I think 无视掉,原句变为:You haven't met Xiao Xin .   步骤3:按照一般方法,后面加上:have you ?   上述做题方法在初中范围内95%是能用的。   2.not…because(of)   这种结构中的 not否定的是后面 because引导的从句或 because of引起的介词短语。也就是说,not从because(of)的前面转移到了主句或整个句子的谓语动词的前面。例如:   He was not ready to believe something just because Aristotle said so.他并不只是因为亚里士多德说过某事如何如何,就轻易相信它。   I didn't take a raincoat because it was raining.我不是因为下着雨才带雨衣的。   3.not…+动词不定式或介词短语   在这类结构中,我们实际上是将否定后面不定式的not转移到了谓语动词上。如:   Jack does not seem to like you.(= Jack seems not to like you.)杰克看来不喜欢你。   He didn't take the boy from the tracks to safety to win his own fame.but to be nefit the boy's parents.   他把男孩从铁轨上抱到安全地带,不是为了获得个人的名誉,而是为了孩子的父母。   He didn't come here by train.他不是乘火车来的。   4.never know......   you never know how indebted i am for your kindest care and your warmest support.   我非常感激你对我无微不至的关心和最强大的支持。
编辑本段形式与用法
谓语的否定转移
  形式上否定主句的谓语,实际上是否定从句的谓语   当动词think, believe, suppose, imagine, expect, feel的主语是第一人称、谓语动词为没有任何副词修饰的一般现在时,它们的否定式实际上是对宾语从句的否定。表示说话者提出一种委婉的看法或主张。如:   I think that he will help us. —I don’t think that he will help us. 我认为它不会帮助我们。   I believe that he is right. —I don’t believe that he is right. 我认为他不对。   I suppose that he likes it. —I don’t suppose that he likes it. 我想他不喜欢它。   2. 形式上否定谓语动词,实际上否定复合宾语   当动词think, believe, suppose, imagine, expect, feel, find的主语是第一人称、谓语动词为没有任何副词修饰的一般现在时,它们前面的否定式实际上是对复合宾语的否定。表示说话者所提出的一种委婉的看法或主张。如:   I think math difficult. — I don’t think math difficult. 我认为数学不难。   I find the story interesting. — I don’t find the story interesting. 我认为这个故事没有趣。   I expect so. —I don’t expect so. 我认为不会。
状语的否定转移
  有些句子形式上否定谓语动词,实际上是对句子后面状语进行否定。如:   Let’s not talk about it here. 我们别在这里谈吧。   Don’t read in the sun. 不要在阳光下看书。   Don’t talk with your mouth full of food. 不要口里含着食物说话。
注意
  动词think, believe, suppose, imagine, expect, feel在下列情况下,否定不转移:   (1) 这些动词跟其他另一个动词一起做并列谓语时,否定不转移。如:   I believe and hope he won’t do that. 我相信并且也希望他将不会那样做。   I feel and admit that we are not foolish. 我觉得并且也承认我们并不愚蠢。   (2) 用于疑问句时,否定不转移。如:   Do you think it is not going to rain? 你认为天不会下雨吗?   Don’t you believe that he has done a good thing? 难道你不相信他做了一件好事?   (3) 用作插入语时,否定不转移。如:   Li Lei, I think, won’t be angry with you. 我想李蕾不会生你的气。   Tom, I suppose, won’t be against it. 我猜想汤姆不会反对。   Mike, I believe, hasn’t seen the film. 我认为迈克没有看这场电影。   (4) 动词前有其他副词修饰时,否定不转移。如:   I really don’t think it’s necessary for us to go there now. 我的确不认为我们有必要去那儿。   I feel strongly that he shouldn’t do such a thing. 我强烈地认为他不应该做那样的事。   (5) 动词为非一般现在时或主语不是第一人称时,否定不转移。   I thought that he wouldn’t come back soon. 我原以为他不会回来得这么快。   She didn’t believe that he became a good boy. 她不相信它变成了一个好孩子。   He thinks that he isn’t fit for the job. 他认为他不适合这件工作。   He doesn’t believe that what we told him is true. 他不相信我们告诉他的事是真的。   (6) 当宾语从句中含的否定为not…at all, not a little, not a few, not enough, can’t help等固定搭配时,否定不转移。如:   I think that he doesn’t know it at all. 我想他对那一点也不知道。   I suppose that it is not enough to remember the words if you want to learn the language well. 我认为如果你想把这门语言学好,那么只记单词是不够的。   I believe that you can’t help singing our national anthem when you win the first place in the Olympic Games. 我相信当你在奥运会上获得第一名时你会情不自禁地唱起国歌来。   (7) 当宾语从句中含no, nothing, nobody, nowhere, hardly, seldom, little, few等否定词或半否词时,否定不转移。如:   I believe that nothing can make me give it up. 我想任何事情也不能使我放弃。   I think that no one can escape if the ship sinks in the sea. 我认为如果这艘船沉入海底的话,那么谁也逃不掉。   I suppose that he is a man of few words. 我猜想他是一个言语不多的人。
经典例句
  1.在带宾语从句的复合句中,如果主句的谓语动词是think, believe, suppose, expect, guess, fancy, feel, imagine等表示“观点、信念、推测”等心理活动的动词时,否定谓语从句的not往往转移到主句,成为“形式否定主句,意义否定从句”,这种语法现象就叫做否定转移。如:   I don’t think he will come this afternoon.   我认为他今天下午不会来。   I don’t believe I have the pleasure of knowing you.   很遗憾,我并不认识你。   I don’t guess that they have got married.   我猜他们还没有结婚。   I don’t expect they have finished the work..   我料想他们还没有完成工作。   I don’t suppose he will return to his hometown after a few years of study abroad.   我看他在国外学习几年后不会回家乡了。   I don’t feel you should go.   我觉得你不应该去。   I didn’t imagine that Tom would help her.   我猜想汤姆不会帮助她。   2.主句中的谓语动词若与情态动词或状语连用时,不转移否定。   I can’t believe that they are married.   我真不敢相信他们结婚了。   We can’t believe that he turns an honest penny.   我们不能相信他是用正当手段挣钱。   You mustn’t think he’s an honest person.   你不可以认为他是一个诚实的人。   I didn’t ever suppose that they were happy.   我并不认为他们是幸福的。   但是,在带有can’t和couldn’t的句子中,有时can’t和couldn’t带有否定转移的含义。如:   She can’t seem to do it. (=She seems not to be able to do it.)   她似乎不能做这件事。   3.当think用在疑问句中时,不转移否定。   Why do you think I can’t change your note?   你为什么认为我换不开你的钞票呢?   4.由knew, fear, mean, I am afraid等动词形式构成的宾语从句中,其否定词not,通常不进行否定转移。当然,这并不是说否定词not不能否定以上动词形式,而是说否定宾语从句和否定主句谓语动词的意思不同。试比较:   He knew you wouldn’t tell on him.   他知道你不会出卖他。   He didn’t know you should tell on him.   他没想到你竟会出卖他。   I mean you didn’t do it right.   我是说你做得不对。   I don’t mean you did it right.   我并不是说你做的对。   I am afraid that he won’t threaten me with death.   恐怕他不会以死来威胁我。   I am not afraid that he will threaten me with death.   我不怕他以死来威胁我。   5.动词hope不可进行否定转移。   I hope it won’t snow.   我希望天不下雨。   I hope she doesn’t dislike the flowers.   我希望他不会讨厌(会喜欢)这些花。   6.在下列几种情况下,think的宾语从句中的否定词通常不可前移到主句中:   1) 宾语从句中有固定短语,如can’t help, not at all, not only… but also… 等。   I think everybody can’t help laughing if they see it.   我认为,人们看到时会禁不住大笑。   I think she is not only beautiful but also kind.   我认为,她不仅漂亮,而且善良。   2) 宾语从句中not与just, enough, quite, much等副词连用。如:   I think you are not quite sure about it.   我认为,你们对这一点并不能完全肯定。   I think she’s not much like her mother.   我觉得,她不怎么像她的母亲。   3) 宾语从句中含有no, nothing, never, nobody等。如:   I think she has never been there.   我认为,她从未去过那里。   4) think本身有其他词修饰或与其他动词构成并列谓语。如:   I sometimes think he is not an honest man.   我有时认为她并不诚实。   I do think you shouldn’t hurt her.   我的确认为你不该伤害她。   I think and hope that I’m not disturbing you so much.   我认为,也希望,我不太打扰你。   5)think以过去时、完成时等出现,则不一定要求否定前移。如:   I was thinking that he wouldn’t succeed.   我在想他不会成功。   I thought you didn’t marry her.   我原以为你不会与她结婚。   I had thought he wouldn’t come.   我愿意为他不会来呢。   但是,在现代英语中,为了使语气柔和,过去时态的句子中偶尔也可见到这种否定转移。如:   I don’t think this man would want to hurt me.   我想,这个人不会伤害我。   6)think的主语不是I或we,而是其它人称。如:   They think she will not come.   他们认为她不会来。   7.在现代英语中,下面两句都可以说:   I don’t think he will succeed.   I think he won’t succeed.   我认为他不会成功。

是指宾语从句是否定的话,可以将否定词前移至主句使得主句变为否定语句。
