（你去和她见面时会发现）“你应该认识她”（因为你和她合作过），请把引里的句子翻译成英文。

你去和她见面时会发现when you meet her and you will find...

你应该认识她 you should know her!

因为你和她合作过because you used to work together with her.

You may know her.

should强调的是某人应当做某事，类似一种责任。中英文的感觉不一样，中文虽然说的是你应该认识她，但是其中的意思是有可能会认识她，而不是说你不认识她就不对。因此，个人感觉用may比较好。

你去和她见面时会发现:when you go to meet her,you will find..(sth)
你应该认识她You should know(about her)
因为你和她合作过:Because you and she have cooperated

you may recognize her once you have a glance of her.
once you meet her ,you will find that you have cooperated with her in surprise
To your surprise ,you will find that you have cooperated with her before.

You should have known her. ——should have done sth.是原本应该…但是事实上却没…的意思！

you should've known her
