解析：
【小题1】根据答语I’m visiting my grandmother for vacation.可知，本句应该是问“你假期干什么？”故填What are you doing for vacation?
【小题2】根据She lives in Tianjin“他住在天津”可知，本句应该是问“她住在哪里？”故本句应该是Where does she live?
【小题3】根据答语It takes about six hours to get there by train可知，本句是问“乘火车到那里要花多长时间？”故本句应该是How long does it take to get there by train?
【小题4】根据I’m leaving on Friday“我星期五离开”可知，上句应该是问“你什么时间离开？”所以本句应该是when are you leaving？
【小题5】英语中别人祝福我们时，我们应该表示感谢，根据Have a good time可知，我们此时应该说Thank you.
