521　do you think可以用作插入语

　在特殊疑问句中，常用do you think 作插入语，结构为：疑问词（+被修饰成分） +do you think +其他成分，表示询问对方的看法或意见。因为do you think 已经表示疑问，所以特殊疑问句只能用陈述语序。

Which of these books do you think is the best？这些书你认为哪一本最好？

How much money do you think I can lend to him？你认为我能借给他多少钱？

How many people do you think I should invite？你认为我应该邀请多少人？

Who do you think can answer this question？你认为谁能回答这个问题？

Whom/Who do you think we should invite to our party tonight? 你认为我们该邀请谁来参加我们今晚的聚会？

What do you think has happened to her? 你认为她发生了什么事？

A： Why do you think he didn't attend the meeting? 你认为他为什么没有参加会议 ？

B： He fell ill. 他病了 。

提示

上面第一句的which和第四句的who均作主语，即使去掉插入语do you think，词序仍不变。
