Passage Three
London taxi drivers know the capital like the back of their hands. No matter how small and indistinct the street is, the driver will be able to get you there without any trouble. The reason London taxi drivers are so efficient is that [32]they have all gone through a very tough training period to get a special taxi driving license. [33]During this period, which can take from two to four years, the would-be taxi driver has to learn the most direct route to every single road and to every important building in London.
To achieve this, most learners go around the city on small motorbikes, practicing how to move to and from different points of the city. [34]Learner taxi drivers are tested several times during their training period by government officers. Their exams are a terrible experience. The officers ask you, "How do you get from Buckingham Palace to the Tower of London?" And you have to take them there in a direct line. When you get to the tower, they won't say "Well done"; they will quickly move on to the next question. After five or six questions they will just say "see you in two months' time" and then you know the exam is over. [35]Learner drivers are not allowed to work and earn money as drivers. Therefore, many of them keep their previous jobs until they have obtained their license. The training can cost quite a lot because learners have to pay for their own expenses on the tests and a medical exam.

Questions 32 to 35 are based on the passage you have just heard.
32. Why are London taxi drivers very efficient?
正确答案：B
解析：题目询问为什么伦敦的出租车司机效率非常高。关键是要听到“伦敦的出租车司机效率非常高是因为在获得专门的出租车驾驶执照之前，他们都经历过一段十分艰苦的训练时期。”也就是说接受过特殊训练，即B。因为有驾照所以工作效率就高，A本身就不符合常理，故不正确；选项C、D的内容文中均未提及。
33. How long does the training period last?
正确答案：D
解析：题目询问训练期有多长。关键是要听到“这段训练时期，时间从两年到四年不等，……”故答案为D。符合“同义替换”的原则。选项A具有一定的干扰性，若未注意到months这个时间单位的错误，则可能误选A。
34. Why does the speaker think the driving test is a terrible experience?
正确答案：B
解析：题目询问为什么作者认为驾驶考试是一场可怕的经历。关键是要听到“驾驶考试是一场可怕的经历”之前的那句话：实习出租车司机在训练期内要参加好几次由政府官员主持的考试。选项B与其同义，故正确。选项A、C、D的内容文中均未提及。
35. Why do learner drivers have to keep their present jobs?
正确答案：C
解析：题目询问为什么实习出租车司机必须保有他们目前的工作。关键是要听到“不允许实习出租车司机以司机身份工作赚钱。”即C。A、D两项文中未提及；文中说实习出租车司机不能以司机身份赚钱，所以他们不可能从两份工作中同时赚钱，故B错误。
