【正确答案】 D

【答案解析】[解题指要] 本题测试交际英语。I'm glad to hear that可以用来表示“很高兴听到对方所说的事情”。
如：Sally：We have a nice car, finally.
Mary: I'm glad to hear that.
Tom: Is your sister feeling better?
Bill: Oh, yes, thanks.
Tom: Glad to hear that.
选项A = Oh, thank you very much.
选项C应是I had a really good weekend at my uncle's的延续，而非答语。选项B表示祝贺，与情景不符。
