Question

I don’t think he has completed the task , ____________?

A．does he

B．do I

C．hasn’t he

D．has he

Answer 1

D

试题分析：考查反义疑问句。本句是一个否定前移句，本来的语序为I think he has not completed the task.句中的I think作为插入语可以省略，句子就变成了he has not completed the task,其反义疑问句为has he.故D正确。
点评：反义疑问句要注意否定前移和插入语的用法，本题的I don’t think既是否定前移也是插入语。
