2. 在have no idea 之后常用wh-引导同位语从句.

I have no idea where he has gone. I have no idea when he did it. I have no idea what he did.

注: 1. that 引导同位语从句与that 引导定语从句的区别: 引导同位语从句的that 无实际意义, 不作从句的任何成分, 而引导定语从句的that 从句的某个成分.

He told me the news that our team won the match. He told me the news that was very exciting. We are interested in the news that some foreigners would visit our school. We are interested in the news that he told us.
