英語四級語法知識：否定轉(zhuǎn)移

1) 將think, believe, suppose, expect, fancy, imagine等動詞后面賓語從句的否定詞轉(zhuǎn)移到主句中，即主句的謂語動詞用否定式，而從句的謂語動詞用肯定式。

I don't think I know you.　我想我并不認識你。

I don' t believe he will come.　我相信他不回來。

注意：若謂語動詞為hope,賓語從句中的否定詞不能轉(zhuǎn)移。

I hope you weren't ill. 我想你沒有生病吧。

2) 將seem, appear 等后的從句的否定轉(zhuǎn)移到前面。

It doesn't seem that they know where to go.

看來他們不知道往哪去。

It doesn't appear that we'll have a sunny day tomorrow.

看來我們明天不會碰上好天氣。

3) 有時將動名詞，介詞短語或整個從句的否定轉(zhuǎn)變?yōu)閷χ^語動詞的否定。

I don't remember having ever seen such a man.

我記得從未見過這樣一個人。 (not否定動名詞短語 having…)

在這里，人們不會想到在街上會碰上陌生的人。

(anyone 作主語，從句中的謂語動詞不能用否定形式。)
