理工類AB級輔導資料:完形填空Car Thieves Could
Speeding off in a stolen car， the thief thinks he has got a great catch.But he is in a nasty surprise.The car is fitted with a remote immobilizer（使車輛不能調動的裝置）， and a radio signal from a control center miles away will ensure that once the thief switches the engine _1_ ，he will not be able to start it again.
For now， such devices _2_ only available for fleets of trucks and specialist vehicles used on construction sites.But remote immobilization technology could soon start to trickle down to ordinary cars.and _3_ be available to ordinary cars in the UK _4_ two months.
The idea goes like this.A control box fitted to the car incorporates _5_ miniature cellphone，a microprocessor and memory， and a GPS satellite positioning receiver. _6_ the car is stolen， a coded cellphone signal will tell the unit to block the vehicle‘s engine management system and prevent the engine _7_ restarted.
There are even plans for immobilizers _8_ shut down vehicles on the move，though there are fears over the safety implications of such a system.
In the UK.an array of technical fixes is already making _9_ harder for car thieves.“The pattern of vehicles crime has changed，”says Martyn Randall of Thatcham.a security research organization based in Berkshire that is funded in part _10_ the motor insurance industry.
He says it would only take him a few minutes to _11_ a novice how to steal a car， using a bare minimum of tools.But only if the cal-is more than 10 years old.
Modern cars are a far tougher proposition，as their engine management computer will not _12_ them to start unless they receive a unique ID code beamed out by the ignition key.In the UK，technologies like this _13_ achieve a 31 per cent drop in vehicle-related crime since 1997.
But determined criminals ore still managing to find other ways to steal cars.Often by getting hold of the owner‘s keys in a burglary.In 2000，12 per cent of vehicles stolen in the UK were taken using the owner’s keys double the previous year‘s figure.
Remote-controlled immobilization system would _14_ a major new obstacle in the criminal‘s way by making such thefts pointless.A group that includes Thatcham，the police，insurance companies and security technology firms have developed standards for a system that could go on the market sooner than the _15_ expects.
