用一個句子作賓語,這個句子就是賓語從句。賓語從句的三大考點是時態(tài)、語序和引導詞。
當主句謂語動詞是think,believe,suppose,expect,imagine等,后接一個表示否定意義的賓語從句時,其否定通常轉移到主語:如:
I don't suppose that it is true.我認為那不是真的。
I don't imagine that he will come.我想他不會來的。
I don't think we need waste much time on it.我想我們不必在這上面花太多時間
We didn't think we'd be this late.我們沒想到我們會到得這么晚。
I don't suppose I'll trouble you again.我想我不要再麻煩你了。
注意:
在反意疑問句中,這種否定轉移的復合句在進行反意疑問時,助動詞和相應代詞要與從句一致,而且用肯定式。如:
I don't think the boy is clever,is he?我認為那個男孩不聰明,是嗎?
I don't believe it will rain tomorrow,will it?我相信明天不會下雨,是嗎?
