答案：

B. I hope we can go there together.
C. What a good idea!
(答案→)D. I’m afraid that’s not a good idea.
解析：
试题分析:根据语境可知此题考点是shall we+动词原形表示建议表示“我/我们……好吗？”。回答建议的表达方式：(1) 同意对方的建议时，一般用：Good idea. / That’s a good idea.
OK/ All right. Yes, please. / I’d love to. I agree with you. Sure. / Of course. / Certainly.
(2) 对对方的帮助或要求表示委婉谢绝时，一般用：I don’t think so. / Sorry, I can’t. / Sorry, but… I’d love / like to, but … / I’m afraid…因，下文的There must be too many people there.提示可知是谢绝，根据选择项的提示可知选择D。
