1. I don't know what to do. 这里的宾语可以用不定式代替,这样不定式不是宾语,此句只有一个主语,谓语,宾语,就是简单句了
2. I'm sure that I can pass the exam
这里把to pass the exam这一不定式改为宾语从句,
就是一个复合句了
I don't know how to do.后面没有宾语了
I'm sure that I will pass the exam表语从句
1.I don’t know what to do.
2.l'm sure that I'll pass the exam.
I don’t know what to do.
l'm sure i'll/ i can pass the exam.
