Though in the accident, the bus driver did all he could to help the passengers to safety.

网友回答

A. injuring
(答案→)B. injured
C. to injure
D. having injured
解析：考查形容词用法。Injured是动词injure的过去分词转换的形容词，对句子的主语the bus driver进行修饰限制；ACD三项中injure都是动词，后面要接宾语，而题中横线的后面没有宾语。句意：尽管在事故里受了伤，这个公交车司机做了他能做的一切来保证乘客的安全。故B正确。
