Question

【题目】He is too heavy. He has decided_____ some exercise to keep healthy.

A. to take B. not to take

C. take D. taking

Answer 1

【答案】A

【解析】句意：他太重了，他决定做一些锻炼来保持健康。to take 动词不定式；not to take动词不定式的否定形式；take动词原形；taking动名词形式。take exercises做锻炼，是固定短语。句中谓语动词是decide，常用于句型decide to do sth.决定去做某事，因此这里用动词不定式形式，选A。
