Each

24、passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice. Passage One Questions 31 to 35 are based on the following passage. Speeding off in a stolen car, the thief thinks he has got a great

25、 catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobilizer (锁止器), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again. For now, such devices are only available for fleets o

26、f trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars, and should be available in the UK in two months. The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro-processor

27、and memory, and a GPS satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicles engine management system and prevent the engine being restarted. In the UK, a set of technical fixes is already making life harder for car thieves.

28、“The pattern of vehicle crime has changed,” says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old. Modern cars are far tougher to steal, as their engine m

29、anagement computer wont allow them to start unless they receive a unique ID code beamed out by the ignition (点火) key. In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, of

30、ten by getting bold of the owners keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 meters without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred meter

31、s minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicles movements via the cars GPS unit. 31. Whats the function of the remote immobilizer fitted to a car? A) To help the police make a surprise attack on the car
