问题：高一英语“Ifoundthehomeworkwasnotashe 
“I found the homework was not as heavy as what I us to get in my old school.”其中，为什么用"what"?,用“that”可以吗？
回答：不可以用that
这里的what引导的是宾语从句,而你要用that的话就是在用定语从句,两者都是重要考点,在高中英语中出现频繁且易混淆.
用that引导的定语从句前面一定要有先行词,即此句用that的正确说法应该是I found the homework was not as heavy as the homework (that )I used to get in my old school.而且that此处是充当的是宾语,因此还可以省略,the homework就是此句中的先行词
你自己比较一下两者的区别,我可能讲的不是很好.
