问题补充：
The baby is crying. Please do something to make him .
A. stop to cry
B. to stop to cry
C. stop crying
D. to stop crying
答案：
A. stop to cry
B. to stop to cry
(答案→)C. stop crying
D. to stop crying
解析：使役动词make后面的宾补要用动词原形，即“make sb. do sth让某人做某事”故排除答案B和D；stop doing sth停下手头正在做的事情，stop to do sth停下手头的事去做...这里句子应该要表达：宝宝在哭，想办法让宝宝别哭了（停止哭泣）。
