C It’s illegal for the police to attach ...

C

It’s illegal for the police to attach a GPS unit to your car without your permission, as the U.S. Supreme Court settled in 2012. But if the police are in hot pursuit of a bank robber or other escaping criminals that threaten public safety, a GPS tracker is acceptable. But exactly how can the police GPS track a  car that is moving fast?

The answer to that question comes from StarChase, a new police technology being used by a small-but growing number of law enforcement agencies. It allows the police to fire 4.5-inch glue-covered GPS bullet-like projectiles (发射体) from an air gun fixed in their police cars. If the GPS tracker makes contact with the escaping robber’s car, it’ll stick no matter how fast the vehicle is going.  That way, the police will have a constant read on the car’s location and heading. Aside from simply apprehending (逮捕) criminals, it’s believed this new technology could help save lives. If the police successfully fire a GPS unit at a speeding criminal, they can pull back from a high-risk chase. Chases can be incredibly dangerous to all involved, including innocent bystanders and other drivers. Once the GPS bullet connects, there’s no need for the chase any longer.

Now, predictably, a GPS-loaded gun isn’t cheap. Police departments need to pay about $5,000 per vehicle for the technology, and individual GPS bullets cost as much as $250 each. That may sound expensive, but remember: The alternative is often thousands of dollars in property damage, and great human cost in injury and lost life. According to Star Chase, their GPS bullet system has an apprehension rate of 80% without any report of injury or property damage. If you’d like to learn more about the StarChase system, Popular Mechanics has just published a good article about it. There’s also plenty more information available at the company’s website.

1.When the GPS bullet sticks to the escaping robber’s car, the police can______ .

A. know the car’s condition

B. ensure the robber’s safety

C. play a fair game with the robber

D. know the car’s position and direction

2.The GPS bullets could help save lives mainly because

A. the bullets won’t hurt people

B. they can make the robber’s car stop

C. the police can stop the dangerous chasing

D. they have more advantages than normal bullets

3.From the text we can learn that GPS bullets

A. are useful for the police

B. are widely used in America

C. can control the rising crime rate

D. can replace the police in the future

4.In which part of a newspaper can we read the text

A.Life    B.Nature     C.Fashion    D.Technology

That way, the police will have a constant read on the car’s location and heading.可知用来知道抢劫犯的位置与方向,故选D项。 2.C 细节理解题。根据第二段提到If the police successfully fire a GPS unit at a speeding criminal, they can pull back from a high-risk chase. Chases can be incredibly dangerous to all involved, including innocent bystanders and other drivers.可知如果警察把这种装置安在犯罪的车上,他们可以撤出高风险的追逐,避免危及自身以及周围无辜的群众,故选C项。 3.A 推断题。根据最后一段提到According to Star Chase, their GPS bullet system has an apprehension rate of 80% without any report of injury or property damage.根据定位卫星,这个定位装置有个百分之八十的成功率,推断用于警方,故选A项。 4.D 推断题。本文讲述一种新型的GPS定位追踪子弹头,可用来追捕罪犯,来确定他的公位置与方向,也可用来避免高风险的追捕,所以这篇文章出现在科技版面,故选D项。

However urban life strikes you, cities worldwide have been growing every day。However urban life strikes you, cities worldwide have been growing ever more rapidly. Some of this growth has occurred in the developed world, but the most dramatic increase has been in the Third World. Almost all the world’s population growth over the next 30 years will take place in the cities of developing countries

By the year 2030, for the first time in history, 60 percent of the world’s people will be living in cities.

This is actually good news in some ways. “Cities are the fundamental building blocks of prosperity,” says Marc Weiss, chairman of the Prague Institute for Global Urban Development, both for the nation and for families.” Industrial and commercial activities in urban areas account for between 50 and 80 percent of the gross domestic product (GDP) in most countries of the world“ there’s the crazy notion that the way to deal with a city’s problems is to keep people out of them,”Weiss continued. “But the problems of the rural life are even more serious than those of the city.” For better or worse, urban-watchers are clear on one point: The quality of life for most people in the future will be determined by the quality of cities. Those cities will be bigger than ever. And yet, population numbers by themselves don’t determine a city’s prospects; after all, Addis Ababa, Ethiopia, and Hamburg, Germany, have the same population. Nor is explosive growth necessarily the determining factor. “City problems,” one authority points out, “mostly have to do with weak, ineffective, and usually unrepresentative city governments.”

1.In the author’s opinion, _________.

A.better city, better life

B.both urban and rural areas have a larger population

C.the larger population, the faster a city develops

D.both urban and rural areas have larger gross domestic products

2.Which statement is NOT true according to the passage?

A.The developing countries develop faster than the developed countries.

B.Cities contribute more to the GDP than the villagers.

C.Some problems are more easily solved in cities than in country.

D.It’s impossible to solve urban problems by getting people out of cities.

3.The last paragraph implies that ____________.

A.Public services are ineffective.

B.Cities are increasing too fast.

C.Population is not linked with development.

D.Government should be responsible for the problems in the cities.
