Speeding off in a stolen car, the thief thinks he has got a great catch. But he is 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 microprocessor and memory, and a GPS satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control center 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 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 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.
(Note: Answer the questions or complete the statements in No More Than 12 Words)
1.The remote immobilizer is fitted to a car to ____________________________________.
2.By saying “But only if the car is more than 10 years old”, Martyn Randall means that _____________________________________________________________.

Being bored can encourage people's creativity-partly to escape the horrible, frustrated. And meaningless feeling of boredom-recent studies find. It could even be true at work.
Psychologists at the University of Central Lancashire had participants copy numbers out of the telephone book for 15 minutes,while others went straight into a standard creativity task.
Both groups were asked to come up with as many different uses as they could for a plastic cup. The group that felt more bored came up with more uses.
Dr. Sandi Mann, one of the study's authors said. " Boredom at work has always been seen as
something to he removed. hut perhaps we should be welcoming it in order to encourage our creativity. What we want LO do next is to see what the practical implications of this finding are. Do people who are bored at work become more creative in other areas of their work-or do they go homeand write novels?"
In a later study, Dr. Sandi Mann found that creativity was reduced when people were still bored but didn't have the chance to daydream.
While we tend to think of boredom as something; that certainly leads to trouble-drinking, gambling. and antisocial behavior, this research suggests differer possibilities.
More than anything, the feeling of boredom is a 8trong signal that we are stuck in some kind of rut and we need to seek out new goals. In the study above, this research led participants to new ideas.
Usually people will do anything to avoid being bored. as it's such an aversive experience. But creative people, like writers, sometimes talk ahout seeking out boredom.
Here is the comedy writer Graham Linehan talking about boredom Lo The Cuardian. "I have to use all these programs that cut off the Internet,force me to be bored, because being bored is an essential part of writing, and the Internet has made it very hard to be bored. The creative process requires a period of boredom ,of being stuck. That's actually a very uncomfortable period that a lot of people mistake for writer's block, but it's actually just part of a long process. "
So, when you start to feel bored , instead of g7ancing at your smartphone.,try being bored for a bit. Who knows what creative thought might come of it?

Last July, my 12-year-old car died on California’s Santa Ana Freeway. It was hour before sunset, and I was 25 miles from home. I couldn't reach anyone to pick me up, so I decided to take a bus. Not knowing the routes, I figured I’d just head east. A bus pulled up, and I asked the driver how far she was going. “Four more lights,” she said. There was another bus I could take from there. This clearly was going to be a long night. She dropped me off at the end of her route and told me which bus to look for. After waiting 30 minutes, I began to think about a very expensive taxi ride home. Then a bus pulled up. There was no lighted number above its windshield. It was out of service. But the door opened, and I was surprised to find that it was the same driver. “I just can’t leave you here,” she said. “This isn’t the nicest place. I will give you a ride home.” “You will drive me home in the bus?” I asked, perplexed. “No, I’ll take you in my car,” she said. “It’s a long way,” I protested. “Come on,” she said. “I have nothing else to do.” As we drove from the station in her car,, she began telling me a story. A few days earlier, her brother had run out of gas. A good Samaritan（乐善好施者）picked him up, took him to a service station and then back to his car. “I’m just passing the favor along,” she said. When I offered her money as a thank you, she wouldn’t hear of it. “That wouldn’t make it a favor,” she said. “Just do something nice to somebody. Pass it along.”

At a primary school in a small town in the east of South Carolina, second-grade teachers Garneau and Lynne are convinced that separating elementary-age boys and girls produces immediate academic improvement in both genders（性别）．
David Chadwell, South Carolina’s expert of single gender education says, “Boys and girls learn, hear and respond to their surroundings differently．We can teach boys and girls based on what we now know．”
Male and female eyes are not organized in the same way, he explains．The organization of the male eye makes it sensitive to motion and direction．“Boys understand the world as objects moving through space,” he says．
The male eye is also drawn to cooler colors like silver and black．It’s no accident that boys tend to create pictures of moving objects instead of drawing the happy colorful family, like girls do in their class．
The female eye, on the other hand, is drawn to warmer colors like red, yellow and orange．To attract girls, Chadwell says, the teacher doesn’t need to move as much as in boy’s class．Using descriptive phrases and lots of colors in presentations or on the blackboard gets their attention．
Boys and girls also hear differently．“When someone speaks in a loud tone, girls understand it as yelling,” Chadwell says．“They think you’re mad and can shut down．” Girls are more sensitive to sounds．He advises girls’ teachers to watch the tone of their voices．Boys’ teachers should sound more forceful, even excited．
A boy’s nervous system causes him to be more cautious when he is standing, moving, and the room temperature is around 69 degrees Fahrenheit．Stress in boys, he says, tends to increase blood flow to their brains, a process that helps them stay focused．Girls are more focused when seated in a warmer room around 75 degrees Fahrenheit．Girls also respond to stress differently．When exposed to threat and conflict, blood goes to their guts（肠道）, leaving them feeling nervous or anxious．
These differences can be applied in the classroom, Chadwell adds．“Single gender programs are about making the best use of the learning．”
1.What is David Chadwell’s attitude toward separating elementary-age boys and girls while learning?
A．Supportive B．Worried
C．Concerned D．Uninterested
2.To engage boy in a class, the teacher ______．
A．must have a moving object in this hand
B．needs to wear clothes in warm color
C．has to speak politely
D．had better move constantly while teaching
3.Which of the following shows the organization of the passage?
（ ?= Paragraph 1 ?= Paragraph 2 ?= Paragraph 3 …．．． ?= Paragraph 8 ）
4.Which of the following students is most likely to be focused?
A．A boy sitting in a warm room
B．A standing boy who is faced with stress
C．A girl standing in a cold room
D．A girl who is facing a lot of pressure
