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 immobiliser (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 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 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.

I was six when I joined my father and two brothers at sunrise in the hayfields of Eufaula,Oklahoma.By the time I was eight I was helping Dad fix up low-income rent properties.He gave me a penny for every nail I pulled out of old boards.
I got my first real job,at JM’s restaurant in town,when I was 12.My main responsibilities were cleaning tables and washing dishes,but sometimes I helped cook.
Every day after school I would head to JM’s and work until ten.On Saturdays I worked from two until eleven.At that age it was unlucky going to work and watching my friends run off to swim or play.I didn’t necessarily like work,but I love what working allowed me to have.Because of my job I was always the one buying when my friends and I went to the local bar Tastee Freez.This made me proud.
Word that I was honest and hard-working got around town.A local clothing store offered credit to me although I was only in the seventh grade.I immediately charged a $68 sports coat and a $22 pair of trousers.I was making only 65 cents an hour,and I was already $90 in debt!So I learned early the danger of easy credit.I paid it off as soon as I could.
My first job taught me discipline,responsibility and brought me a level of personal satisfaction few of my friends had experienced.As by father,who worked three jobs,once told me,“If you understand sacrifice and commitment,there are not many things in life you can’t have.”How right he was!When the author was a child,he was made to help his father work because_________.

Since long ago,greeting cards have been considered a time-saver.More than 150 years ago,a busy Englishman,Sir Henry,asked a friend to design a card so that he didn't have to labour to write holiday letters to his friends at the end of the year.Those paper cards are now the tradition.
But time,like sunlight,is still in short supply for December.That's why the Internet is ready to make a change in holiday greeting customs.Already,those,who are always busy,like sending video greetings by e-mail.So,don't be surprised to find a lively card in your electronic mail box at the end of the year or at any time you should have one.
A recent survey by the Shared Greetings Company found 50 percent of all the Internet users will send online cards especially during the holiday seasons.“That is a lot easier,and it is lively,”said Carol,a New Yorker,who had stopped at the Shared Greetings Company demonstration() online.With her children's help,she sent her first e-card before Thanksgiving Day.“It was the first time I had done something like this;it's quite enjoyable,”she said.
“I will send online Christmas cards to my friends,”said Marcos,a 22-year-old student.“It costs so little and you can even send numbers of greetings at a time.”But he added “the e-card also has its limits,and I don't think it is ready to replace the paper card for the more formal or traditional occasions.For some people,I would rather buy paper cards and mail them traditionally.I believe it is more personal and respectful in that way,”he said.
Well,for those who are very busy but still prefer to do a lot of greetings to different receivers in the holiday season,the Internet may have another way.“Now you can use the Net to decide and send as many as 50 beautiful cards,which allows the buyer to choose the inside saying,as well as the ink colour and typeface,only costing about 30 minutes,”said Julie,vice-president of marketing for an electronic card company-Hallmark Company.“And if you are in less of a hurry,you can spend another 30 minutes sitting in your home or office to create a photo card,showing off your kids,your pets or even your new house-anything as your favorite design for your relatives and friends.”How can we understand “But time,like sunlight,is still in short supply for December”in Paragraph 2?
| A．December cannot supply enough time for people because the sunlight in this month is short. |
| B．People are always busy at the end of the year,so time is precious like the sunlight in winter. |
| C．Time is short at the end of the year,like the sunlight in December. |
| D．Time passes quickly like the sunlight in winter as December comes. |
According to the 22-year-old student,he would probably mail e-cards to everyone except_________.
| A．the members of his family |
| B．his girlfriend |
| C．the teachers who have taught him |
| D．his schoolmates |
If you are quite busy,but having many greetings to send,which of the following is your best choice?
| A．Ordering a lot of cards you like online and sending them from the post office. |
| B．Getting as many cards from your electronic mail box and mailing them on the Net. |
| C．Sitting and writing lots of beautiful cards at home and sending them just in a traditional way. |
| D．Choosing personalized cards in numbers and mailing them directly on the Net. |
There are new findings that not enough sleep may cause people to gain weight.Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger.
In one study,researchers in the United States examined information on more than 1000 people.The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night.They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours.And they had 15 percent less of the hormone leptin.Experts say ghrelin helps make people feel hungry;leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies.They note the combination that limitation is common and is widely available.
The results were not affected by how much people exercised.People who are awake longer have more time to burn energy.But the researchers say loss of sleep may increase hunger especially for high-calorie foods,so people gain weight.It seems that,for survival,the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study.They found that the best amount of sleep for weight control is 7.7 hours a night.
The Public Library of Science published the findings in its journal Medicine.Internet users can read the full study,free of charge,at plos.org.Which of the following shows the right way in which lack of sleep causes weight gain?
| A．more ghrelin and less leptin→feeling hungry→eating more |
| B．feeling hungry→eating more→more ghrelin and less leptin |
| C．burning more energy→feeling hungry→eating more |
| D．more leptin and less ghrelin→feeling full→less exercise |
The two words missing in the 4th paragraph should be “_________”and “_________”.
| A．weight;sleep | B．sleep;food | C．hunger;food | D．weight;work |
When you sleep 7.7 hours a night,you will_________.
| A．have your ghrelin level rise and leptin level drop |
| B．have your leptin level rise and ghrelin level drop |
| C．have your ghrelin and leptin levels properly balanced |
| D．feel neither hungry nor full |
