答案：
A. I don think so
(答案→)B. Have a good time
C. Thats very strange
D. You should try it
解析：句意：——我和我的父母明天将要去伦敦进行旅行。——真的？祝你玩得愉快。A. I don think so我不这样认为； B. Have a good time祝你玩得愉快； C. Thats very strange那是非常奇怪的； D. You should try it你应该试一试。根据go to London for a trip tomorrow.可知第一个人要去旅行，因此第二个人要祝他玩的愉快。故选B。
