解析：译文：他很受学生欢迎因为他总是努力使他们对他的演讲感兴趣。考点：过去分词做宾语补足语。Sth interests sb→Sb is interested in sth→Sth is interesting to sb→Sb makes sb interested in sth. Reading interests me.→ I am interested in reading.→Reading is interesting to me.→I used not to be interested in reading, but my teachers try to make me interested in reading.
