用existed
一般情况下，
occur强调的“发生”这个动作，例如：itoccursthat......
exist强调的“存在”这个状态，例如sthexist。
efficientmarkets是一个名词，是物，对其只有存在于不存在之分
而“发生”（occur）是对一件事情而言，比如Itneveroccurredtomethathemightbeintrouble.
我怎么也没有想到他会遇上麻烦。
当然occur也有其他用法，但是其最常用的用法就是上面说到的发生，这是其与exist最大的区别。
建议自己可以翻看一下occur和exist各自在字典中的解释和例句，看懂了例句，就能明确区分这两个的用法了~
本文到此结束，希望能对大家有所帮助哦。
