Question

我在《商务英语每日一段》这本书里的同一页里两个不同对话中看到这样的两个句子：
1.Our hope is to establish mutual beneficial trading relations between us.
2.Our hope is to establish mutually beneficial trading relations between us.
为什么同样的两句话既可以用mutual又可以用mutually,这两个有什么用法上的区别吗?

Answer 1

第一句mutual修饰名词relations,第2句是mutually修饰修饰benefical.
