空里填as还是that？为什么？区别是什么？求解答我的疑问，谢谢！

应该为：His behavior is such (that ) everybody dislikes.
翻译为：他的行为是如此的恶劣，以至于任何人都不喜欢。（属于结果状语。）

因为：such……as 和 such……that 的区别是：
such...as用于引导定语从句,such...that 用于引导结果状语从句.如：
I’ve never heard such stories as he tells.我从未听过他讲那样的故事.
It was such a cold day that there was nobody on the street.天气很冷,街上没有一个人.
试比较：
He is such a good teacher as we all respect.他是一位我们大家都尊敬的好老师.(as引导的是定语从句,as 在该定语从句中用作respect的宾语)
He
is such a good teacher that we all respect
him.他是那样一位好老师,以致于我们大家都尊敬他.(that
引导的是结果状语从句,that在该状语从句中不充当句子成分,另外注意句中的respect带有宾语him)
