act 和enact 有什么区别?

enact是及物动词 vt.(transitive verb)
用法比较书面，可以理解为制定(法律);颁布(法案)
比如：
Several bills were enacted at the end of this session of Parliament.
几项法案在这届国会的会议结束时被颁布。
或者还可以理解成上演;扮演(角色)，比如：
They enacted the roles of hero and heroine in the play.
他们在这出戏中担任男、女主角。

而act,作vt.时有如下意思：
1. 扮演
He acted Othello at the Royal Theater that evening.
那天晚上他在皇家剧院扮演奥赛罗。
2. 装出;举动像
He acted the wise man who knew everything and never made mistakes.
他假装成是无所不知,从不出错的聪明人。

在act作不及物动词时vi.有：
1. 行动[(+on/for)]
We should act immediately.
我们应该立即行动。
2. 起作用,见效[(+on/upon)]
3. 假装;演戏,表演
The actress acts very well.
这位女演员的表演非常出色。
4. 扮演,充当[(+as)]
John acted as chairman in his absence.
他不在时,约翰充当主席。
5. 举止,表现[L]
I don't think she acted right.
我认为她做得欠妥。

另外还可以作名词来用n.：
1. 行为;行动
get one's act together
【俚】冷静下来仔细筹划(吸食迷幻药,迷惘失向后重新振作)
My first act was to run into
