高三复习英语单选题,要详细解答
I do not think he could have surfed the internet last night , _____?Ahas he Bcould he Cdid he Ddo I
I do not think he could have surfed the internet last night , _____?Ahas he Bcould he Cdid he Ddo I
选C,首先这是个反义疑问句,当主语是第一人称时,反义疑问句中的主语与后面的从句一致,为he ,所以不选D.主句中don't否定转移,因此前半句就变成了I think he couldn't have surfed the internet last night,而且主句中有明显的过去时间状语标志last night,后面的反义疑问句应该用did 提问,所以答案是did he,选择C.
