a有益于b英语

广州啊？应该有这样的地方的，森淼就是一个啊，专业不说，那些外国老师都特负责呢

A reach for B?不是很确定

the advantage of A compared with B and C.

a need b...

A is good for BA can make B betterIt's better for B to v. A

如果非要用这个句子结构的话,我觉得这样说比较妥当:Not only A,but also B is benefit from it.

It is of benefit to ？？？？ 国外人没有那么说话的 应该是 it is benefit for not only A, but also B但是这是中国式英语 地道的说法 both A and B can benefit from it
