同学好~

borrows一般出现在一般现在时主语是单数第三人称的情况下，是单三的一种标志，比如：
He borrows money from his friends every month.
borrowed有两种可能，一种是borrow的过去式，一种是过去分词：
过去式：在一般过去时中，borrow做谓语，比如：
He borrowed some money from his friends yesterday.
过去分词可能出现在完成时态中，和have/has/had搭配使用，也可能是过去分词做非谓语动词，比如：
He has borrowed some money from his friends so that he could survive.
This is a large amount of money borrowed from his friends.

希望帮到同学~
