(2) n. 运动，（保持健康或培养技能的）一套动作，习题 〖注意〗当exercise解释为“运动”时，是不可数名词；当exercise解释为“（保持健康或培养技能的）一套动作，习题”时，是可数名词。 · Many old people often do exercise in the morning.“做运动”，此时exercise是不可数名词 · Students do eye exercises at about 2 p.m. “眼保健操”，此时exercise是可数名词 · Our teacher asked us to finish the exercises on the book.“习题，练习”，此时exercise是可数名词 2. help with housework 帮助做家务事 （housework是不可数名词） “help with sth.”意为“帮助做某事，在某方面提供帮助” · Lucy is lazy.
