问题
选择题
His father doesn’t allow him _______ games, he always keeps him _______
his homework.
A. to play, to do B. playing, doing C. to play, doing
答案
答案：C
题目分析：allow sb. to do sth.允许某人做某事 allow doing sth., 不可说allow sb. doing sth.
Keep（sb.） doing sth.坚持做某事，一直做某事，故选C
点评：allow to do sth也是错的。在考试中还会考allow的被动语态：sb. be allowed to do sth. Keep sb. from doing sth. 意思与Keep（sb.）doing sth 意思不一样，它的意思是阻止某人做某事。
