本段对话有关参加音乐会及问询感受的话题。
第一空：根据上句“Did you go to the concert last night?”，答语又已经给出“Yes”可知逗号后面肯定回答问句的内容，答案选D。
第二空：根据答语“Wonderful.”可知上句应是询问“你觉得这个音乐会怎么样”，B项符合文意。
第三空：根据整个对话情景，和前句“Many famous singers sang at the concert.”可知下句应是继续谈论有关音乐会的内容，F选项最符合题意。
第四空：根据问句“What does it mean?”可知答句应是回答“音乐会是为贫困地区的儿童筹集资金而举办的”，答案选G。
第五空：根据上句“You know many children in the world don’t have enough food.”，所以下句应表肯定“这倒是真的”。故答案选A。
