Question

过去分词的完成式
____in the traffic accident ,the driver was taken to the hospital at once
C Having badly injured
D Badly injured
我选C答案D
be badly injured 不是发生在be taken to the hospital谓语动作之前的吗,应该用完成式?

Answer 1

1.答案D正确.
2.首先要能判断句子主语the driver和非谓语动词injure的关系,它们之间肯定是被动关系.所以必须用过去分词形式injured.
3.答案A中的having badly injured其实是现在分词injuring的完成形式而已,所以它表明the driver和injure之间为主动关系,所以不对.
4.如果既要表示被动,还要表示完成,需要用having been done而不是having done,所以要选A,则必须改成having been badly injured.
5.另：如果非谓语动词所表示的动作和句子谓语动作在发生时间上非常紧密,可以不必用完成形式来表达.
题中的at once刚好提示了这一点.
