When I was a little boy, my teacher let me admit _______ in the examination, _______ that I wouldn’t do that in future．

A.to cheat; to promise

B.cheating; promised

C.having cheated; promising

D.to have cheated; promised

答案及解析： C

解析：

本题考查非谓语动词。句意为“我小时候, 老师让我承认在考试中作了弊, 并保证今后不再这样做”。由于第二空前没有连词and, 因此admit与promise不应该是两个并列的谓语动词, 用promised就是错误的, 而要用现在分词promising作状语。正确答案为C项。
