All_____B____she could do was to go back home. A.what B.that C.which D.this 什么时候用A？谢谢！
解题思路： all that =what .what引导名词性从句,意为\"所……的事\",相当于\"the thing that...; all that...; everything that....\"等。
解题过程：
选B正确。此句是一个定语从句，先行词是all,she could do 是定语从句部分，该定语从句中句中做主语。如果先行词是all，则关系代词要用that .而what引导的名词性从句,意为"所……的事",相当于"the thing that...; all that...; everything that...."等。如：
1. What I need now is time.
2. All that I need now is time.
最终答案：略
