exercised

基本解释

exercise用作名词的基本意思是“运动,锻炼”。指适用于正常人的一般性的以健身为目的的“体质锻炼”,也可指脑力方面的锻炼,还可指适用于运动员的“专业训练”。
exercise作“练习,习题”解有时可用作定语; 作“使用,应用”解时,其结果常常是有效的; 作“演习,操练”解时常用复数。

exercise的基本含义是反复地进行某一动作或一系列动作,以发展和加强某种能力,尤指为了身体健康或精力充沛而进行的活动。引申可表示“运用”“行使”或“实行”“执行”等。
exercise可用作及物动词,也可用作不及物动词。用作及物动词时,接名词或代词作宾语。
exercise作“练习”解时,其后常接“反身代词+in+ n./v -ing”,其主语既是动作的执行者,又是动作的承受者。
exercise作名词统指“运动”时，前面加冠词特指“某项运动”。We take exercise every morning. Walking is a good exercise.
exercise作名词指“习题”时，后面跟in和科目名称，或on/in和科目的部分的名称，如an exercise in English grammar（英语语法习题），an exercise on/in the construction of conditional sentences（条件句结构的习题）；
graduation/graduating exercises指“毕业典礼”，是美式英语，相当于英式英语中的ceremony；
