It’s humorous you to tell funny jokes to those teenagers.
A. of；lonely
B. of；alone
C. for；alone
D. for；lonely

(答案→)A. of；lonelyB. of；aloneC. for；aloneD. for；lonely解析：考查固定句型和形容词辨析。句意“给这些孤独的青少年讲有趣的故事，你真是太幽默了。”在句型“it is +形容词 for/of sb. to do sth.”中，形容词指人时，用of；指物时，用for。Humorous指人，排除C、D；lonely“孤独的”；alone“单独的，独自一人的”。故选A。
