G：It’s so great seeing you guysagain.
C：Yeah.
B：I agree.
C：I can’t believe it’s been twentyyears since we were all in college together.
G：Yeah, you know, that’s my bestmemory. That peace demonstration. You know, somehow getting arrested forsomething you believe in isn’t … isn’t scary at all.
C：No, it isn’t at all.
B：You’re right.
C：But it did help that there werefive hundred other students getting arrested along with us.
B：That was a great day, though.
G：Hey, hey, you all remember ourlast day of college?
B：What, you mean graduation?
C：Graduation, what’s to remember?None of you went to graduation. I didn’t go.
what’s to remember? 查阅了一些资料，有表示“计划”、“安排”、“义务”、“应该”、“可能”、命”等，还有一种表示，不定式做表语，表示主语和表语在定义上是等同的。那样，怎么样理解的beto do结构使用方法。
我在网上查了一下，这是新编大学英语4视听说课程原文Unit 7的对话内容。我的语法常识告诉我这个问句是个语法错误，应该修改如下：
Graduation, what’s to remember? 错误
Graduation, what’s for you to remember? 正确
Graduation, what's to be remembered? 正确
Graduation, what's there to remember? 正确
Graduation, what's there to be remembered? 正确
