I promise that I won't let ----you referred -----.

promise that I won't let all you referred to happen.
填进去后分析真个句子：
（我）承诺：我将不让所有你所指的事情发生.如果去掉外层的动宾结构:I won't let all you referred to happen..
我不会让事情发生,是什么事情呢?就是你所指的所有事情.
最基本的内层结构：I won`t let *** happen.
这里有个语法：let sb.(sth.) do.
refer to 是定语后置,介词必须保留.
分析完了句子,你就明白了其他答案是错误的了.
