Car Thieves Could Be Stopped Remotely
Speeding off in a stolen car,the thief thinks he has got a great catch.But he is in a nasty surprise .The car is fitted with a remote immobilizer,and a radio signal from a control center miles away will ensure that once the thief switches the engine______(51),he will not be able to start it again.
For now,such devices______(52)only available for fleets of trucks and specialist vehi- dles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars,and ______(53)be available to ordinary cars in the UK______(54)two months.
The idea goes like this.A control box fitted to the car incorporates______(55)miniature cellphone, a microprocessor and memory, and a GPS satellite positioning receiver.______(56)the car is stolen,a coded cellphone signal will tell the unit to block the vehicle's engine management system and prevent the engine______(57)restarted.
There are even plans for immobilizers______(58)shut down vehicles on the move, though there are fears over the safety implications of such a system.
In the UK,an array of technical fixes is already making______(59)harder for car thieves."The pattern of vehicles crime has changed,"says Martyn Randall of Thatcham,a secur- ity research organization based in Berkshire that is funded in part______(60)the motor insur-ance industry.
He says it would only take him a few minutes to______(61)a novice 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 a far tougher proposition,as their engine management computer will not______(62)them to start unless they receive a unique ID code beamed out by the ignition key .In the UK,technologies like this______(63)achieve a 3 1 percent 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 in a burglary. In 2000,12 percent of vehicles stolen in the UK were taken by using the owner's keys,which doubles the previous year's figure.
Remote-controlled immobilization system would______(64)a major new obstacle in the criminal's way by making such thefts pointless.A group that includes Thatcham,the police,insur-ance companies and security technology firms have developed standards for a system that could go on the market sooner than the______(65)expects.

Eastern Quakes Can Trigger Big Shakes
In the first week of November 2011,people in central Oklahoma experienced more than two dozen earthquakes. The largest,a magnitude 5 .6 quake,shook thousands of fans in a college football stadium,caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV,you see reports about all sorts of natural disasters一 hurricanes,tornadoes,flooding and wildfires,to name a few. But the most dangerous type of natural disaster,and also the most unpredictable,is the earthquake.
Researchers at the U. S. Geological Survey estimate that several million earthquakes rattie the globe each year. That may sound scary,but people don't feel many of the tremors because they happen in remote and unpopulated regions.Many quakes happen under the ocean, and others have a very small magnitude,or shaking intensity.
A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23, 2011,was felt from central Georgia to southeastern Canada. In many urban areas,including Washington,D.C.,and New York City(Wall Street shown),people crowded the streets while engineers inspected buildings.
Scientists know about small,remote quakes only because of very sensitive electronic devices called seismometers.These devices detect and measure the size of ground vibrations
produced by earthquakes.Altogether,USGS researchers use seismometers to identify and locate about 20,000 earthquakes each year.
Although earthquakes can happen anywhere in the world,really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen,on average,only once each year. Such big ones typically occur along the edges of Earth's tectonic plates.
Tectonic plates are huge pieces of Earth's crust,sometimes many kilometers thick. These plates cover our planet's surface like a jigsaw puzzle. Often,jagged edges of these plates temporarily lock together. When plates jostle and scrape past each other,earthquakes occur. On average,tectonic plates move very slowly一about the same speed as your fingernails grow.
But sometimes earthquakes rumble through portions of the landscape far from a plate's edges. Although less expected,these”mid-plate” tremors can do substantial damage. Some of the biggest known examples rattled the eastern half of the United States two centuries ago. Today,scientists are still puzzling over why the quakes occurred and when similar ones might occur.
Seismometers can identify and locate most of the earthquakes in China.

Will We Take Vacation in Spaces?
When Mike Kelly first set out to build his own private space-ferry service,he figured his bread-and-butter business would be lofting satellites into high-Earth orbit. Now he thinks he may have figured wrong.“People were always asking me when they could go,”says Kelly,who runs
Kelly Space TechnologT out of San Bernardino,Californi a.“I realized that real market is in space tourism.”
According to preliminary market surveys,there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington,Virginia,has taken more than 1 30 deposits for a two-hour,$98,000 space tour tentatively(and somewhat dubiously)set to occur by 2005 .Gene Meyers of the Space Island Group says:“Space is the next exotic vacation spot.”
This may all sound great,but there are a few hurdles.Putting a simple satellite into orbit with no oxygen,life support or return trip necessary already costs an astronomical $22,000/kg.
And that doesn't include the cost of insuring rich and possibly litigious passenger. John Pike of the
Federation of American Scientists acerbically suggests that the entire group of entrepreneurs trying to corner the space tourism market have between them“just enough money to blow up one rocket.”The U .S.space agency has plenty of money but zero interest in making space less expensive for the little guys.So the little guys are racing to do what the government has failed to do:design a reusable launch system that's inexpensive,safe and reliable.Kelly Space's prototype looks like a plane that has sprouted rocket engines.Rotary Rocket in Redwood City,California,hasa booster with rotors make a helicopter-style return to Earth;Kistler Aerospace in Kirkland,Wash- ington,is piecing together its versions from old Soviet engines,shuttle-style thermal protection tiles and an elaborate parachute system.The first passenger countdowns are still years away,but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations.After all,you can't be too prepared for a trip to that galaxy far,far away.
For those who are intent on joining the 100-mile high club,Hilton and Budget are plotting to build space hotels.Before the Russian space Mir came down,some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space,and if you're thinking of staying in it,you may want to check the Michelin ratings before booking yourself a suite.

Every Dog Has His Say
Kimiko Fukuda always wondered what her dog was trying to say.Whenever she put on make-up,it would pull at her sleeve.______(46)When the dog barks,she glances at a small elec-tronic gadget（装置）.The following" human" translation appears on its screen; "Please take me with you.""I realized that's how he was feeling."says Fukuda.
The gadget is called Bowlingual,and it translates dog barks into feelings.People laughed when the Japanese toymaker Takara Company made the world's first dog-human translation ma-chine in 2002 .But 300,000 Japanese dog owners bought it.______(47)
"Nobody else had thought about it."said Masahiko Kajita,who works for Takara."We spend so much time training dogs to understand our orders;what would it be like if we could understand dogs?"
Bowlingual has two parts.______(48)The translation is done in the gadget using a data-base containing every kind of bark.
Based on animal behavior research,these noises are divided into six categories:happiness, sadness,frustration,anger,declaration and desire.______(49)In this way,the database scien-tifically matches a bark to an emotion,which is then translated into one of 200 phrases.
When a visitor went to Fukuda's house recently,the dog barked a loud"wow wow".______(50)It was followed by"I'm stronger than you"as the dog growled and sniffed（嗅）at the visitor. The product will be available in US pet stores this summer for about US$120.It can store up to 100 barks,even recording the dog's emotions when the owner is away.
______(46)
A: A wireless microphone is attached to the dog's collar,which sends information to the gadget held by the owner.
B: Nobody really knows how a dog feels.
C: This translated as"Don't come this way".
D: More customers are expected when the English version is launched this summer.
E: Now,the Japanese girl thinks she knows.
F: Each one of these emotions is then linked to a phrase like"Let's play","Look at me",or "Spend more time with me".
