    According to the passage, which of the following did NOT happen in the room where the college entrance exam was going on?
    A

    The teachers in the exam hall tried to stop the police from entering into the room.

    B

    Some examinees sent answers with mobile phones to people outside the room to make profits.

    C

    The mobile phones were confiscated by the police.

    D

    Some examinees forwarded answers to people who have paid a lot of money.


    正确答案: A
    解析:
    语义的理解和判断。该段录音与一次考试作弊案相关,开头便指出警察试图进入学生参加大学入学考试的大厅,但是“They were blocked by teachers but later confiscated mobile phones…”,由此可知,虽然教师们不让警察进入考试大厅,但后来警察们还是没收了被用于考试作弊的手机,因此选项A、C均与录音原文相符。接着录音中指出考场里最聪明的学生将答案做出后,发给younger students outside the hall(考场外年纪小一点的学生)手中,然后这些学生再将答案转发给已付过钱的人,由此可见,B项内容也与录音原文相符。但D项所描述的(一些考生将答案转发给已付过钱的人)与录音中提到的“发给考场外年纪小一点的学生”不符。
    【录音原文】
    Acting on a tip off—the police tried to raid a hall where students were taking the college entrance exam last month. They were blocked by teachers but later confiscated mobile phones that had been smuggled into the room—and uncovered what they said was an elaborate cheating system. The brightest students known as “players” finished their multiple choice papers quickly then sent off the answers by text message to younger students outside the hall. They forwarded the information to others who paid up to 1, 000 dollars to take part.
