I hope ---- A ．him to pass the exam B．he to pass the exam C.him can pass the exam D .he can pass

D
hope后可跟动词不定式to do,但不说hope sb.to do,所以A不对
B和C更不对
hope后面也可跟宾语从句,这里可以省略关系代词that,所以D正确（从句中主语、谓语、宾语都全而且用得也对）
再看几个例句加深印象：
He hopes to have the problem settled as soon as possible.
他希望能尽快使这个问题得到解决.
I hope to have seen the film next week.
我希望下星期能看到这部电影.
We hope that we will be better paid.
我们希望得到更好的报酬.
