compels, compelled, is compelled, to do, doing, is doing A man can not be happy if he ________ by society to do what he does not enjoy ______.
【正确答案】：is completed; doing
【题目解析】：本句的意思是一个人如果为社会所迫去做他不喜欢做的事，他不可能开心。根据句中的cannot 和does not和句子意思应该用一般现在时，而表示“被迫”应用被动式，所以用is compelled, 注意compel的过去分词形式为compelled。Enjoy后面要用名词或动名词作宾语，所以用doing。
