Question

【题目】I advised Joe to keep ______ regularly in order to lose weight.

A.to exerciseB.exercisedC.exercisesD.exercising

Answer 1

【答案】D

【解析】

句意：我建议乔保持经常锻炼以减轻体重。

考查非谓语性动词。to exercise锻炼，动词不定式；exercised锻炼，过去式；exercises锻炼，动词三单；exercising锻炼，现在分词或者动名词形式；根据句意理解可知，这里表达的是“保持锻炼”，英语是keep doing sth，所以这里应该用ing形式，故选D。
