转移否定

转移否定,即句中的否定虽然出现在谓语部分,否定范围却不在主句谓语动词本身,而转移到了句子中的宾语、状语或其他成分上。这种形式在初中比较常见的有以下两种情况:

1.转移否定多用于表思维活动

如:believe(相信), expect(期望), hope(希望), imagine(想象), think(认为)等。

例如:I don't think he will pass the exam.

我认为他考试会不及格的。

2.主句的谓语动词是表感觉的系动词,通常也用于转移否定句

这类动词有:seem(好像), feel(感觉), appear(出现), look like(看起来像)等。例如:

It doesn't look like it's going to rain.=It looks like it isn't going to rain. 好象不会下雨。

No matter how hard he studies, he never seems to be able to pass the exam. 不管他多么努力的学习,他似乎永远也考不及格。

 

运用某些结构表达否定意义

1.too...to 太……而不能

He is too tired to walk. 他太累了,走不动了。

2.more A than B(与其B不如A)或more than +含有can的从句

The young man is more brave than wise.

这年轻人有勇无谋。

The gratitude for your help is more than I can express.

对于你给我的感激之情我无法言表。

3.prefer to do sth rather than do sth 宁愿(喜欢)……而不愿……,例如:

He prefers to write his letters rather than dictate them.

他喜欢自己写信而不愿口授自己的信。


运用含否定意义的词或词组表否定意义

1.动词短语表否定意义,如:

differ from 与……不同

prefer...to... 喜欢……而不喜欢……

keep/prevent/stop/protect ... from 阻止,使……不

keep off 不接近, 不让……接近

lose sight of 看不见

例如:

The Great Green Wall stops the sand from moving to the rich land in the south. 绿色长城阻止了风沙吹向南方肥沃的田地。

He lost sight of his wife and went away alone.

他没看见他的妻子,独自走了。

Sally prefers singing to dancing.

莎丽喜欢唱歌而不喜欢跳舞。

2.动词表否定意义

如,absent(缺席), fail(不及格), refuse(拒绝), miss(未赶上,错过), escape(被……忘掉)等。例如:

Why did you absent yourself from school yesterday?

昨天你为什么不来上学?

He missed the 9:30 train and therefore missed the accident.

他没赶上9:30的那班火车,也因此而逃过那次车祸.

3.介词表否定意义

without(无,没有), against(反对), beyond(超出,无法), except/but(除……外), past(超过), off(离开), above(超出……之外)等。例如:

I can't finish the work without your help.

没有你的帮助,我完不成这工作。

His conduct has always been above suspicion.

他的行为一直无可置疑。

His stupidity is past all belief.

他的愚蠢简直不可思义。

 

运用连词before unless等引导的状语表否定意义

例如:

王伟没完成作业就睡觉了。

Unless you put on your overcoat, you'll catch a cold.

如果你不穿大衣,你就会感冒
