因為make是使役動詞，後面接sb，再接動詞時，需要用動詞原形做賓語補足語。
make sb do：讓某人做某事。
分析：這是壹個動詞短語。
make （動詞）sb （賓語，用賓格）do（賓語補足語）。
例如：
In order to make him accept our suggestion, I decided to work on him immediately.
為了讓他接受我們的建議，我決定立刻對他做工作。
Make him do some eye exercises after studying, which would be really good for his sight.
讓他在學習完之後，做壹下眼保健操，這對他的視力很有好處。
Then put his hands on your sensitive part, which may give him confidence that you need him and make him carry on.
然後把他的手放在妳身體的敏感部位，這既可以給他信心，也表明妳想要他，鼓勵他做下去。
