Why is 跟 in 陈叶可以直接拿跟胡灵阳的钥匙? I wrote this:


  ...陈叶可以直接借她的钥匙。


I intend for it to mean "Chen Ye can directly borrow her [Hu Lingyang's] keys", as in, he doesn't need to ask---the keys were on the table, and he just took them and walked off (they're good friends and trust each other).  My teacher changed it to the following (I think):


  ...陈叶可以直接拿跟胡灵阳的钥匙。


I don't understand why 跟 is in here, and I feel it should be deleted.  This may be my misunderstanding, as I'm looking at corrections I made from a WeChat conversation from a while ago.  Although maybe I'm missing something.

陈叶可以直接拿跟胡灵阳的钥匙


The 跟 doesn't look quite right in the sentence.  It implies that 陈叶 and 胡灵阳 share the keys. That's not what you intended to mean according to your English sentence.  On the other hand, it's not a good sentence.  

So, it should be removed: 


  陈叶可以直接拿胡灵阳的钥匙
