记忆方法:  1）首字母记忆DTMH排序成MHDT梦回大唐<==逢场做戏      做戏的意思是演戏，比喻做出某种姿态给人看，如他只是在人前做戏。  逢场做戏原指旧时走江湖的艺人遇到适合的场合就表演；后指遇到机会，偶尔凑凑热闹，如他从来不打扑克，这次不过是逢场做戏，应酬一下客人而已。  

          2）除dramatic是中性，表示令人激动引人遐想外，其余3个都是贬义，histrionic表示像表演做戏一样虚假虚伪，theatrical强调（像剧院里一样）夸张做作，melodramatic贬义更重，严重的theatrical夸张做作，贬义最强

          3）做戏的意思是像在演戏mean having a character or effects typical of acted plays.
