act, action, deed, operation
1.act和action常可替换,但act多指短暂的、单一的、个人的、具体的行为,强调后果; 而action多指时间较长、过程较复杂的持续动作或行为,有时也指抽象的行动,强调过程。deed指比较复杂或业已完成的行为,多指伟大的、感人的行为; operation常指几个工作的组合。
2.act和deed是可数名词; action常用作可数名词,有时用作不可数名词; operation可用作可数名词或不可数名词。
3.act和operation是一般用词; action是较正式用词; deed是正式用词。
act, act out
1.act的宾语一般是戏剧或角色, act out的宾语则可以是故事、对话等。
act as, act on
这两个短语都可译作“起作用”,但含义并不相同, act as是“以…身份而起作用”; act on是“对…起作用”。也就是说act as的宾语是“起作用”的主体; 而act on的宾语则是“作用”客体。
act as, act for
1.act as后接表示职务的名词,而act for后多接人称代词,而少接职务名词。
2.act as强调的是职务,而act for强调的是所代替的人。
3.带有act for句中的职务是临时的; 而act as后接的职务既可是临时的,又可是长期的。
4.act as后接职务的是一个人,而担任act for句中的职务者有两个人,其中for后的人是正式的,长期的, act的逻辑的主体则是代理的,临时的。
5.act as后接的(职务)名词前往往省略冠词; 而act for后接的名词一般情况下有the。
act as, act like
它们并非同义短语,后者只是一种自由搭配。它们的区别很明显:前者的意思是“是”,后者的意思是“像(而不是)”。另外, as后常省略冠词,而like后则多用冠词。再有, as短语一般看作主语补语(表示主语身份),而like短语一般看作方式状语。
act as, serve as
serve as多指长期供职; 而act as所指时间则相对较短。试比较:
He serves as manager and interpreter.
She will act as my guide tomorrow.
act the fool, act like a fool
