action的基本意思是“行動(dòng),活動(dòng)”,指某一次行動(dòng)的方式或過程,尤指為制止壞的局面發(fā)展或繼續(xù)的行動(dòng)、對(duì)他人來說是錯(cuò)誤或不尋常的舉止行為、激動(dòng)人心的或重要的活動(dòng),往往占較長(zhǎng)的時(shí)間,包括不同步驟或許多動(dòng)作,其主語常為物,而不是人。action也可指進(jìn)行中的“行為”,還可指故事、戲劇或電影的“情節(jié)”,藥物或化學(xué)品等的“作用; 效果”,“戰(zhàn)斗; 作戰(zhàn)”等。
action用作可數(shù)名詞時(shí),多用于復(fù)數(shù)形式。action的復(fù)數(shù)形式在泛指人的“行為”時(shí),常與words相對(duì)應(yīng)。
action在表示戲劇或書中所發(fā)生的主要事件時(shí),常用其單數(shù)形式,其前加定冠詞the。
action在有修飾語時(shí)可加不定冠詞,但在take action中,即使有形容詞修飾,也不加不定冠詞。

action偶爾可用作動(dòng)詞,指“采取行動(dòng)”或“采取措施”,含所采取的行動(dòng)或措施是“適當(dāng)?shù)摹币馕丁?
action與act區(qū)別:action常指持續(xù)，復(fù)雜的動(dòng)作，而act則是短暫，簡(jiǎn)單的動(dòng)作。如有人倒在地上，扶他起來，是act，若不但扶他起來，還幫他叫車，送他到家，那是action；
act of cruelty，act of folly，act of kindness等后面都是接of和抽象名詞，只可用act,不可用action；
cruel act(ion)，foolish act(ion)，kind act(ion)等前面用形容詞修飾時(shí)，同act相比較，更習(xí)慣于用action；
