action用作可數(shù)名詞時,多用於複數(shù)形式。action的複數(shù)形式在泛指人的“行爲”時,常與words相對應。
action在表示戯劇或書中所發(fā)生的主要事件時,常用其單數(shù)形式,其前加定冠詞the。
action在有脩飾語時可加不定冠詞,但在take action中,即使有形容詞脩飾,也不加不定冠詞。

action偶爾可用作動詞,指“採取行動”或“採取措施”,含所採取的行動或措施是“適儅的”意味。
action與act區(qū)別:action常指持續(xù)，複襍的動作，而act則是短暫，簡單的動作。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等後麪都是接of和抽象名詞，衹可用act,不可用action；
