问题描述:

don't worry too much about ______mistakes.they are ______ natural part of learning something.
A.the; / B./; a
为什么不可以是a?be part of 也有的啊

后面那个也可以不填的,确实有这种用法,这里起关键作用的是前面那个,因为mistakes 是复数,泛指的,不可以用定冠词the来修饰,除非表达一个种类的时候,比如说我喜欢骑自行车,可以说I love riding bikes/a bike/the bike
都可以的,语法上没有任何错误,关键是看你习惯哪一种用法了
