I don't think Li Lei is a good student.
问题描述：
I don't think Li Lei is a good student.
这是一个否定前置的句子．我想问如果主语不是第一人称用否定前置吗?
我的意思是如果think 后的宾语从句如果是否定句，主句不论主语是第几人称都要否定前置吗？如：she thinks Li Lei is not a good student.这个句子对吗？
答
不是的.
请看以下资料：
要将think,believe,suppose,expect,fancy,imagine等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式.
I don't think I know you.我想我并不认识你.
I don' t believe he will come.我相信他不回来.
注意：若谓语动词为hope,宾语从句中的否定词不能转移.
I hope you weren't ill.我想你没有生病吧.
