举一反三的答案和解析：

[单选题]Passage FourOne evening Mr. Green was driving home along a lonely country road. He had ￡ 100.00 in his pock et. At the loneliest part of the road, a man asked for a lift (搭车). Mr. Green told him to get into the car and continued his driving. When he talked to the man and learned that the man had been in prison for robbery and had broken out of prison two days before, Mr. Green was very worried.

a prisoner who had escaped from prison

解析：本题是对有关人物细节信息的考查。其中关键词是man．．．lift．．．was。首先，考生从选项中得知需判断搭车人的身份。通过第1段倒数第2句中的．．．the man．．．in prison for robbery．．．broken out of prison two days before了解到此人曾因抢劫而入狱，但又于两天前越狱逃走。 A、B、D项都与文中内容不符，应被排除。唯有C项(越狱的犯人)合乎文中情节，是正确答案。
