drama.play.opera的区别 应该都是戏剧吧,但具体区别不是很清楚

play： [C] work (written to be) performed by actors; drama 戏剧; 剧本:
* a radio play 电台广播剧
* a fine edition of Shakespeare's plays 莎士比亚戏剧集
*She has just written a new play. 她刚写完一部新剧.
* act/take part in a play 在一剧中[参加一剧的]演出
* We are going to see the new play at the Playhouse.
我们要到大剧院看新剧

我们说连续剧（比如说韩剧）的时候都用drama...很少用opera..
感觉opera是在舞台上的表演.比如 peking opera~
