正歌剧 meaning in English

opera seria

Albert threw himself on the divan , tore off the cover of two or three of the papers , looked at the theatre announcements , made a face seeing they gave an opera , and not a ballet ; hunted vainly amongst the advertisements for a new tooth - powder of which he had heard , and threw down , one after the other , the three leading papers of paris , muttering , " these papers become more and more stupid every day .
阿尔贝往长椅上一靠，翻了几张纸的前面几页，然后仔细读了一下戏目，当他看到上演的是一个正歌剧而不是歌舞剧的时候，就做了个鬼脸，他想在广告栏中找到一种新出的牙粉，这是他听别人谈到过的，但却没能找到，于是，他把巴黎的三大流行报纸一份接一份地甩开，自言自语地说道： “这些报纸真是一天比一天地乏味。 ”
