1、do you think 作插入语的用法用于混合疑问句中。混合疑问句指特殊疑问句一般疑问句 do you think 相当于一个一般疑问句 混合疑问句的句式： 特殊疑问词do you think（或其他表示心里活动的词）陈述语序“陈述语序”非常重要。 What can I do？是一个特殊疑问句，如果中间插入 do you think 则后面必须改为陈述语序What do you think I can do ？ 因此 do you think 并不是是插入语。因为它影响句子的语序，上面的例子只不过是凑巧 what 是句子的主语，所以语序没变而已When_declare our marriag
2、e to our friends?A.do you think we shouldB.do you think should weC.you think we shouldD.you think should weWhat do you think( )A.he will say B.will he say 如：which movie is successful? 可以改成：which movie do you think is successful?选项 get such a book? A.Where do you think can I B.Where do you think I can 我的理解是 do you think 是插入语，不去看它，剩下来的是 Where can I such a book?是个一般疑问句，所以选 A，但是答案是 B答：选 B 项是正确的。 do you think 在句中是插入语。使用这种含插入语的句式时要注意两点：(1)应将特殊疑问词置于句首；(2) 插入语后面用陈述句语序。常用于这种句式的插入语还有 do you suppose/believe/guess/imagine 等。
