问题补充：

Little Tom admitted in the examination, that he wouldn’t do that in future.

A. to cheat; to promise

B. cheating; promise

C. having cheated; promising

D. to have cheated; promised

答案：

A. to cheat; to promise

B. cheating; promise

(答案→)C. having cheated; promising

D. to have cheated; promised

解析：考查考查固定搭配和分词用法。第一空考查了固定结构admit doing sth/having done承认做某事；第二空的动词promise与句子主语little Tom构成主动关系，故使用现在分词的形式。句意：小Tom承认在考试中作弊了，发誓以后再也不这样做了。故C正确。
