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 (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.

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 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(=smallest) 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 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, 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 stolen 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 the police informed of the vehicle's movements through the car's GPS unit.

57. The remote immobilizer is fitted to a car to ______.

A. allow the car to lock automatically when stolen

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

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

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

58. By saying “The pattern of vehicle crime has changed”, Martyn Randall suggests that ______.

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

59. Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?

A. To allow for possible errors in the GPS system.

B. To give the driver time to contact the operations centre.

C. To keep the police informed of the car's movements.

D. To leave time for the operations centre to give an alarm.

60. The operations centre will first ______ after receiving an alarm.

A. start the tracking system. B. contact the car owner.

C. block the car engine. D. locate the missing car.

     Much has been written about body language during a job interview. Experts from across many fields
are full of advice on just how to present your best performance in an interview using conscious (自觉的)

If you go into the woods with your friends, stay with them. If you don’t, you may get lost. If you do get lost, though, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you. You can help them to find you by staying in one place.

There is another way to help your friends or other people nearby to find you. Give them a signal by shouting or whistling three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help. You will be helped by others.

Keep up the shouting or whistling, always three times together. When people hear you, they will know that you are not making noise for fun. They will let you know they have heard your signal by giving two shouts, two whistles or two gunshots. When a signal is given twice, it is an answer to a call for help. If you don’t think that you will get help before night comes, try to make a little house with branches, lots of leaves and grass.

What would you do if you get hungry or need drinking water? You have to leave your little branch house to look for a brook. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back.

The most important thing to do when you are lost is--- stay in one place.
