根据句意和汉语注释，写出单词的正确形式。
【小题1】The famous person often makes some speeches (演讲)on protecting wild animals.
【小题2】He feels happy by volunteering (志愿) to work for the charity.
【小题3】They have no money to affordmedical (医学) treatment
【小题4】They are very interested in these inventions (发明).
【小题5】He performed (表演) so wonderfully yesterday.

解析：【小题1】考查名词的复数。根据some“一些”可知，用speech的复数形式。故填speeches。【小题2】考查固定搭配。by是介词“通过”的意思，后加动词的ing形式。故填volunteering。【小题3】考查固定短语。medical treatment“医学治疗”。故填medical。【小题4】考查名词的复数。these“这些”，后加名词的复数。故填inventions。【小题5】考查时态。根据yesterday可知，用一般过去时。故填performed。
