Speeding off in a stolen car, the thief thinks he has got a great catch.But he is in for an unwelcome surprise.The car is fitted with a remote immobilizer, 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.

The idea goes like this.A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS (全球定位系统) satellite positioning receiver.If the car is stolen, a coded (编码的) cellphone signal will tell the control centre to block the vehicle’s 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.“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 management computer won’t allow them to start unless they receive a unique ID code sent 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, often by getting hold of the owner’s keys.And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.

If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen.The hundred metres 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 vehicle’s movements via the car’s GPS unit.

       A.prevent car theft by sending a radio signal to the car owner

       B.help the police make a surprise attack on the car thief

       C.prevent the car thief from restarting it once it stops

       A.it takes a longer time for the car thief to do the stealing

       B.self-prepared tools are no longer enough for car theft

       C.the thief has to make use of computer technology

       D.the thief has lost interest in stealing cars over 10 years old

________ is necessary in making a modern car tougher to steal.

       A.A coded ignition key          B.A unique ID card

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our possibility to give and receive support from one another under stressful (有压力的) conditions. Social support makes up of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.

Social support cushions stress in a number of ways. First, friends, relatives and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力) us from our worries and troubles. Finally, other people may give us instrumental support money aid, material resources, and needed services - that reduces stress by helping us resolve and deal with our problems.
