They did ____ save the wounded soldiers. A. what they could B. that they could do C. all that they could D. all that they could do 老师，我觉得AC都对，请详细解答
解题思路： 如下
解题过程：
此题无正确答案。
They did ____ save the wounded soldiers. 此空应该填all that they could to或what they could to 。
动词不定式短语 to save the wounded soldiers用作目的状语的，表示“为了...”。
to save the wounded soldiers = in order to to save the wounded soldiers
all that they could （do)是一个定语从句， what they could （do)是what引导的宾语从句 ，都省略了动词do ,后面的动词不定式做目的状语。
而选项A和C都缺少一个不定式符号to ,所以都不能选。
最终答案：略
