Are you sure that...that引导什么从句?

问题描述:

Are you sure that...that引导什么从句?

Are you sure that...?that引导的是宾语从句。不过有的语法家把这样的结构叫做状语从句。类似这样的形容词有:afaid,pleased等。

宾语从句,换成陈述句语序是i am sure that....sure是动词,后面可以直接跟从句作宾语

同位语。。。

引导的是同位语从句

Are you sure that 引导的是宾语从句 连接词that无意义,在从句中不充当任何成分,可以省略
Are you sure that we'll have class tomorrow?
也可以说
Are you sure we'll have class tomorrow?
