Question

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

Answer 1

C

試題分析：allow sb. to do sth.允許某人做某事 allow doing sth., 不可說allow sb. doing sth.
Keep（sb.） doing sth.堅持做某事，一直做某事，故選C
點評：allow to do sth也是錯的。在考試中還會考allow的被動語態：sb. be allowed to do sth.      Keep sb. from doing sth. 意思與Keep（sb.）doing sth 意思不一樣，它的意思是阻止某人做某事。
