Singing Alarms Could Save the Blind
If you cannot see, you may not be able to1 find your way out of a burning building—and that could be fatal. A company in Leeds could change all that2_____1____ directional sound alarms capable of guiding you to the exit.
Sound Alert, a company_____2_____ the University of Leeds, is installing the alarms in a residential home for _____3_____ people in Sommerset and a resource center for the blind in Cumbria._____4______ produce a wide range of frequencies that enable the brain to determine where the ______5____ is coming from.
Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be_______6_______ by humans. “It is a burst of white noise白噪音：音響或電力嗓音 ____7____ people say sounds like static靜電噪聲 on the radio,” she says. “Its life-saving potential is great.”
She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of3 a large ____8___ room. It ____9____them nearly four minutes to find the door ____10____ a sound alarm, but only 15 seconds with one.
Withington studies how the brain _____11____ sounds at the university. She says that the _____12____ of a wide band 波段of frequencies can be pinpointed 極微小的more easily than the source of a narrow band. Alarms _____13_____ the same concept have already been installed on emergency vehicles.
The alarms will also include rising or falling frequencies to indicate whether people should go up _____14___ down stairs. They were ____15____ with the aid of a large grant from British Nuclear Fuels.

Car Thieves Could Be Stopped Remotely遙遠地 Speeding off超速行駛 in a stolen car, the thief thinks he has got a great catch2. But he is in a nasty3 surprise. The car is fitted with a remote immobilizer, 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 trucks4 and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle慢慢地移動 down to ordinary cars,5 and ______3____ be available to ordinary cars in the UK____4____two month The idea goes like this. A control box fitted to the car incorporates6 ____5_______ miniature cellphone, a microprocessor and memory, and a GPS7 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 move8, though there are fears over the safety implications of such a system. In the UK, an array of9 technical fixes10 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 Berkshire11 that is funded in part _____10______ the motor insurance industry. He says it would only take him a few minutes to _____11______ a novice新手, 初學者 how to steal a car using a bare minimum of tools12. But only if the car is more than 10 years old. Modern cars are a far tougher艱苦的 proposition任務：13, as their engine management computer will not _____12____ them to start unless they receive a unique ID code beamed out 14 by the ignition key. In the UK, technologies like this _______13______ achieve a 31 per cent drop in vehicle-related crime15 since 1997. But determined criminals are 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.
