答案选C。动词不定式的一般式形式表示将要做的事,(医生竭尽全力)The doctor did what he could 就是为了去挽救那个在事故中严重受伤的女孩(to save the girl who was badly hurt in the accident)。 to save the girl who was badly hurt in the accident整体是动词不定式短语作状语,表示目的。 to save动词不定式;the girl是to save 的宾语;who was badly hurt in the accident是定语从句,修饰the girl。 如果能帮到你就请采纳。 祝你进步,新年快乐!
