字面直译是“做一件好事”,更贴合语境的翻译是“行善”“做善事”(强调具体的、有善意的行为)。
该短语是动词短语,核心结构为:
主语 + do (时态/人称变化) + a good deed (+ 修饰成分)
时态变化:根据语境调整“do”的形式(过去式did,第三人称单数does,现在分词doing等)。
例:
I did a good deed yesterday— I returned a lost wallet to its owner.(我昨天做了件好事——把捡到的钱包还给了主人。)
She always does a good deed for her neighbors, like watering their plants when they’re away.(她总帮邻居做善事,比如邻居不在时帮他们浇花。)
常与for sb.(为某人)或by doing sth.(通过做某事)搭配,补充细节:
例:
He did a good deed for the homeless man by buying him a hot meal.(他为那个无家可归的人做了件好事——给他买了份热饭。)
Doing a good deed anonymously (匿名地) is even more meaningful sometimes.(有时匿名行善更有意义。)
当表示“习惯性或多次行善”时,用复数good deeds:
例:
Volunteering at the shelter is a way to do good deeds regularly.(在收容所做志愿者是定期行善的一种方式。)
鼓励他人行善:Why not do a good deed today? It could brighten someone’s day!(今天为什么不做件好事呢?它能让别人开心一整天!)
评价他人行为:It’s nice of you to do a good deed for the elderly lady.(你帮那位老太太做善事,真贴心。)
总结:"do a good deed"是强调具体善意行为的常用短语,适用于描述“单次或多次行善”,通过添加修饰成分可更精准表达行为细节。
