try your best to encourange her so that she may succeed in her jios interview

这是一个条件句,整句应是If you try your best to encourage her so that she may succeed in her job's interview.这实际上是can（could）和may的区别,一、can的用法：①表示有能力做某事,意为“能、会”.如：The girl can sing in English.②表示许可,意为“可以”,如：You can drive my car to the post office.③表示推测,意为“也许,可能”.如：He can’t be your brother,you don’t look the same.二、may的用法：①表示请求,语气比can弱.如：–May I use your eraser?– Certainly.But you must give it back to me soon.②表示推测,意为“也许,可能”.如：She may be at home.Let’s go to see him.实际上它们只有一点小区别,等你上了大学就会知道这些并不重要.
