Charles did what he could ---the servant ,although he himsel

同学,很高兴回答你的问题才看到你发来的求助题,所以回答晚了些正确答案：选【B】即：Charles did what he could to rescue the servant,although he himself was in danger。翻译：查理斯尽他所能来救这个仆人,尽管他自己的处境也很危险。解析：是的,我们都知道情态动词后面加动词原形,但是本句中what引导的宾语从句中的could后面省略了动词do,而to rescue 是动词不定式作目的状语,即Charles did what he could do to rescue the servant,although he himself was in danger。只不过是这个do省略了,为了避免重复。^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^不明白请继续追问,^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
