(答案→)1. chatting
解析：
【小题1】考查固定短语。be interested in sth/doing sth“对（做）某事感兴趣”。故填chatting。
【小题2】考查词形转换。music“音乐”；musician“音乐人”。根据定语从句的引导词who可知，先行词指人，且从句谓语是原形，先行词是复数。故填musicians。
【小题3】考查固定短语。medical research“医学研究”。故填medical。
【小题4】考查时态。根据句意可知，这里用一般过去时。drop要双写p。故填dropped。
【小题5】考查副词。修饰动词应该用副词。clearly“清楚地”。故填clearly。
