Think后的句子一定要否定转移吗

动词think后的从句一定要否定前移吗？

云南省昭通市威信县第二中学杨天喜（657900）

在人教版高中英语必修三（p18）有这么一个句子：I don’t think it’s very funny.

大家都知道，这是一个典型的否定前移的句子。在宾语从句中，若主句谓语动词是think, believe, suppose, expect, guess, fancy, feel, imagine等表示心理活动的动词时，宾语从句不能用否定形式，若宾语从句是否定句式，则常将否定词not前移到主句谓语动词前面，从而形成“形式上否定主句，实际上否定宾语从句”的现象，这种语法现象叫做否定前移。但是必须注意的是：这种特殊句型的主语一定是第一人称I或者we，若是第二三人称代词（不论单复数）做句子主语，便不能形成否定前移。如：

I don’t think he will come this afternoon.我认为他今天下午不会来。

What a pity! I don’t believe I know 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。

任何语法规则都有例外，如果属于下列情况，则不进行否定前移：

1．主句中的谓语动词若与情态动词或者副词连用时，不否定前移。如：

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。

I mustn’t think he’s an honest person.我一定不会认为他是一个诚实的人。

I didn’t eve r suppose that they were happy. 我并不认为他们是幸福的。

We really think he is not fit for his office. 我们真的认为他不适合这项工作。

I sometimes think she doesn’t work hard. 我有事认为他学习不努力。

I can’t believe that they are married. 我不会相信他们结婚了。

I think you ought not to walk at night alone, Mrs. Moore.摩尔夫人，我认为你晚上不应该独自一人出来。

I sometimes think he is not an honest man.我有时认为她并不诚实。

2．当think用在疑问句中构成双重疑问句时，不用否定迁移。如：

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？Do you think he can’t come here tomorrow? 你认为他明天不能来这儿吗？

Why do you think I can’t do it? 你为什么认为我不会做它呢?

Do you think my father won’t agree? 你认为我父亲不会同意吗?

3．当think前有强调词do/does/did表强调时，不用否定前移。如：

I do think he is not married. 我一定认为他还没有结婚。

We do think you should not stay up late. 我们的确认为你不应该熬夜那么晚的。

I do think you shouldn’t hurt her.我的确认为你不该伤害她。

4．当I think, I believe等被看作插入语成分、和其他部分无关时不用否定前移。如：

She, I think, was not telling the truth. 她，我认为，并没有说出事情的真相。Mary, I believe, is not a good student. 玛丽，我想，并不是一个好学生。

I wish you were here, then, I think, I should not feel like this. 但愿你那时在这儿就好了，（可）我想，我不应该有这样想法。

5. 宾语从句中若有固定短语，如can’t help doing sth, not…at all, not only…but also…, not just (only)... but （also），just not... enough，cannot …to…, cannot but, not at all, not…but…等时，不进行否定前移。如：

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。

I think you cannot praise her too highly. 我热内你无论如何表扬她都不过分。

I think he is not at all tired. 我想他一点也不累。

I guess there isn’t enough food for our lunch. 我想我们午饭没有足够的吃的了。

6. 宾语从句中若有just not enough, not quite, not much等以not中心的表达法连用时，不进行否定前移。如：

I think she’s not much like her mother.我觉得，她不怎么像她的母亲。

I think you don’t quite know me. 我想你不大认识我。

I think I have not enough money to buy a house of my own. 我想我们没有足够的钱来买属于我们自己的房子。

I think I’m just not smart enough to make any sense of you.

But I think that Elizabeth was not quite so certain of it as I.

7. 动词think本身有其他词修饰或与其他动词一道构成并列谓语时，不进行否定前移。如：

I think and hope that I’m not disturbing you so much.我认为，也希望，我不太打扰你。

I think and hope that you should not take the side of him. 我认为，也希望你不应该支持他。

8. 动词think以过去时、完成时等时态出现时，不进行否定前移。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。

I have often thought one shouldn’t only think of himself.

9. 当宾语从句中有no，never, hardly, seldom, little, few, nothing ,nobody, no one等否定词时, 不进行否定前移。如：

I believe John never tells a lie.我相信约翰从不撒谎。

I think Jim can hardly ride a bike.我认为吉姆几乎不会骑自行车。

I thought it explained nothing.
