Many people believe that traveling abroad has a lot of benefits, among which are experiencing a countrys culture, traditions, foods and even, learning its language.
老师好！这句话中的among which为何加are experiencing，如此不就没主语了吗？
among which are experiencing a countrys culture, traditions, foods and even, learning its language
这个定语从句是倒装句。among which 是表语，are为复数谓语动词，主语为并列的动名词短语experiencing...and learning...。
提问之前自己先考虑！
