     A million motorists leave their cars filled up with petrol and with the keys in the ignition (点燃) every day.

The cars are sitting in petrol stations while drivers pay for their fuel. The Automobile Association(A.A) has

discovered that cars are left unattended for an average three minutes and sometimes longer as drivers buy

drinks, sweets, cigarettes and other consumer items.With payment of credit cards becoming more and more

common, it is not unusual for a driver to be out of his car for as long as six minutes, providing the car theft

with a golden opportunity.

     For more than ten years there has been a big rise in car crime than in most other types of crime. An average

of more than two cars a minute are broken into or stolen in the UK. Car crime accounts for almost a third of

all reported offenses with no signs that the trend is slowing down.

     Although there are highly professional criminal involved in car theft, almost 90 percent of car theft is

committed by the opportunists. Amateur thieves are aided by our own carelessness. The A.A. recommends

locking up whenever you leave the car and for however short a period. A partially open sunroof or window is

a further come-on (诱惑) to thieves.

     There are many other traps to avoid. The A.A. has fond little awareness among drivers about safe parking.

Most motorists questioned made no efforts to avoid parking in quiet spots-just the places thieves love. The A.A.

advises drives to park in places with people around because thieves don't like audiences.
