think的否定前移用法及理解
來源:魅力女性吧 1.87W
無論第幾人稱。think都要否定轉移。
人稱和否定轉移唯一有特殊變化的是體現在 反義疑問句上。
一、否定轉移
當think, believe, suppose, imagine, expect等動詞後接的賓語從句為含有not的否定句時,該否定應移至主句,即否定主句的謂語動詞。例如:
I don't think it will rain tomorrow.
We don't expect our football team will win the World Cup.
二、反意疑問句的構成視情況不同有兩種
think, believe, suppose, imagine, expect等動詞後接賓語從句在構成反意疑問句時,視情況不同有兩種不同的構成方式。
1、當主句的主語為第一人稱時,其後的簡短問句應與從句相一致。例如:
I expect our English teacher will be back this weekend, won't she
值得注意的是,當這些動詞後接的賓語從句的否定轉移到主句時,其仍屬否定從句,故其後的簡短問句應用肯定式,而非否定式。
2、當主句的主語為第二、三人稱時,其後的簡短問句則應與主句相一致。例如:
Your sister supposes she needs no help, doesn't she?
You thought they could have completed the project, didn't you?
三、簡略回答用so或not
口語中,可以用so或not替代這些動詞之後的肯定或否定的賓語從句,以避免重複。例如:
1、 - Are you able to come to our party tomorrow?
-I think so.
