I have ___ that he will surely come,but I have ___when he will come

题目

I have ___ that he will surely come,but I have ___when he will come
A an idea of /no idea of
B a mind / no thought
C a thought / not known
D an idea / no idea

答案

D
我认为他一定会来,但是我不知道他什么时候会来.
前后都是idea的同位语从句
前面为that引导的从句,idea后面不接of
后面为when引导的从句,idea后面接of,不过of可以省略
mind更侧重于意志方面的心理内容
thought是想法,不合适.
