Scientists have examined the benefits of a concerted effort to study and practice music,as opposed to playing aMozart CD or a computer-based“brain fitness” game once in a while.
请不要翻译这个句子,只是想请问下三个语法问题:
1 as opposed to分开理解的话,as是作句子什么成分?opposed又是什么成分?to xxx呢?
2 to 后面为什么是ing形式动词?
3 可见这个逗号即使没有也没什么关系,请问这里的逗号是什么用法,起什么作用?
