.首先, interest可当动词来用,请看有道解释：
V-TIf something interests you, it attracts your attention so that you want to learn or hear more about it or continue doing it. 使感兴趣例： Your financial problems do not interest me. 我对你的财务问题不感兴趣.V-TIf you are trying to persuade someone to buy or do something, you can say that you are trying to interest them in it. 引起 (购买或做某事) 的意愿 例： Can I interest you in a new car? 我给你介绍一下新车,你感兴趣吗?
这里动词用法,本身就是让.使.的意思
其次,make作宾语补足语的用法：这是我直接粘过来的
1、动词原形,即不带to的动词不定式,如： He made me stay with him.他让我和他在一起. How did Ling Feng make the baby stop crying?凌风是怎样使婴儿停止啼哭的?
2、形容词（词组）如： This made all the street as light as day. 这使整条街道亮如白昼. He tried to make them happy. 他设法使他们高兴. It'll made me so happy. 这件事可使我如此高兴.
3、名词（词组）如： I would make you king over the earth.我会让你做国王统治世界. He made her his wife.他娶她为妻. All work and no play makes Jack a dull boy.只有工作没有娱乐使杰克脑子极为迟纯.（只工作不学习,聪明的孩子也变傻）.
4、有时可用介词短语.如： He asked us to make ourselves at home. 他要我们不要拘束.
5、过去分词如： What make him so frightened?是什么原因令他如此害怕?
这个肯定是第2 种用法
所以答案是 make sb interested in sth
