Question

Opera originated in Italy but was not confined to Italy any more than the Italians were.
这里的 any more than 用法是啥?
（Opera originated in Italy but was not confined to Italy any more ）- 戏剧不再局限于意大利,这不就完事了么 怎还加了个 than the Italians were.

Answer 1

这句话后面被省略了,全句是
Opera originated in Italy but was not confined to Italy any more than the Italians were confined to Italy.
翻译：
“歌剧”不比意大利人更局限于意大利得多.
意思：
意大利人不会因为国籍的限制而不可以到别的地方去,所以歌剧虽然源发地在意大利,但也不只是在意大利才有.
