Federal regulators Wednesday approved a plan to create a nationwide emergency alert（警报）system using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years，particularly among young people.The wireless industry’s trade association, CTIA，estimates（估计）more than 48 billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act，a 2006 federal law that requires improvement to the nation's emergency alert system.The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies.
“The ability to deliver accurate and timely warnings.and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public.has the information they need to take action to protect themselves and their families before, and during,disasters and other emergencies. ”FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alert system by carriers—telecommunications companies is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alerts.
There would be three different types of messages，according to the rules.
The first would be a national alert from the president，likely involving a terrorist attack or natural disaster.The second would involve “approaching threats，”which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction（绑架）emergencies,or so-called Amber Alerts.
The service could be in place by 2010.
【小题1】 What is the purpose of the approved plan?

Cities alarmed by deaths and injuries of pedestrians are taking efforts to make crosswalks safer for people on foot, especially seniors and children who need more time to cross streets.
A pedestrian is killed in a traffic accident in the USA every 110 minutes; one is injured every nine minutes, according to official data. Crosswalks can be especially dangerous for the elderly. Among people 70 and older, 36% of pedestrian deaths in 2006 occurred in crosswalks, compared with 21% of those younger than 70, according to the Insurance Institute for Highway Safety.
The Federal Highway Administration(FHWA) advise that next year states increase by nearly 15% the amount of time traffic lights provide for pedestrians to cross the street after the flashing orange hand appears.
FHWA spokesman Doug Hecox says reasons for the change include an aging population that needs more time to cross, health-conscious Americans walking more, children encouraged to walk to prevent getting overweight and high gas prices pushing people to walk instead of drive.
Pedestrian deaths went down by 12% from 5,449 in 1996 to 4,784 in 2006, Bur among those in 2006, 471 were killed in crosswalks, down slightly from 488 ten years earlier, the National Highway Traffic Safety Administration(NHTSA) says.
【小题1】Which of the following is true according to the text?
| A．Among 100 pedestrian deaths there were 21 people younger than 70 |
| B．Old people are more likely to meet with accidents happened per hour. |
| C．Traffic accidents killed more old people than young people |
| D．About seven traffic accidents happened per hour. |
| A．Fixing more traffic lights |
| B．Providing more crosswalks |
| C．Giving pedestrians more time to cross streets. |
| D．Drivers don’t give way |
| A．There’re many cars and buses on the road. |
| B．Pedestrians are careless. |
| C．Crosswalks are crowded. |
| D．Drivers don’t give way. |
| A．fewer people were injured in crosswalks |
| B．crosswalk safety has been greatly improved |
| C．much has been done to reduce traffic accidents |
| D．pedestrian deaths in crosswalks remain a serious problem |

2010 was the year the Earth struck back.
Earthquakes, heat waves, floods, volcanoes, super typhoons, blizzards (暴风雪), landslides and droughts killed at least a quarter million people in 2010 – the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.
“It just seemed like it was back-to-back(接二连三) and it came in waves,” said Craig Fugate, who heads the US Federal Emergency Management Agency. It handled a record number of disasters in 2010.
“The term “100-year event’ really lost its meaning this year.”
And we have ourselves to blame most of the time, scientists and disaster experts say.
Even though many disasters have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and strange year for everything from wild weather to earthquakes.
Poor construction and development practices make earthquakes more deadly than they need be. More people live in poverty in vulnerable buildings（危房） in crowded cities. That means that when the ground shakes, the river floods, or the tropical cyclone hits, more people die.
Disasters from the Earth, such as earthquakes and volcanoes “are pretty much constant,” said Andreas Schraft, vice president of catastrophic perils for the Geneva-based insurance giant Swiss Re. “All the change that’s made is man-made.”
The January earthquake that killed well more than 220,000 people in Haiti is a perfect example. Port-au-Prince has nearly three times as many people – many of them living in poverty- and more poorly built shanties(棚户区) ,than it did 25 years ago. So had the same quake hit in 1985 instead of 2010; total deaths would have probably been in the 80,000 range, said Richard Olson, director of disaster risk reduction at Florida International University.
Climate scientists say Earth’s climate also is changing thanks to man-made global warming, bringing extreme weather, such as heat waves and flooding.
The excessive(过多的) amount of extreme weather that dominated 2010 is a classic sign of man-made global warming that climate scientists have long warned about. They calculate that the killer Russian heat wave – setting a national record of 111 degrees – would happen once every 100,000 years without global warming.
Data show that 18 countries broke their records for the hottest day ever.
“The Earth strikes back in response to bad human decision-making,” said Debarati Guha Sapir.” “It’s almost as if the policies, the government policies and development policies, are helping the Earth strike back instead of protecting from it. We’ve created conditions where the slightest thing the Earth does is really going to have a surprising impact.” White House science adviser John Holdren said we should get used to climate disasters or do something about global warming. “The science is clear that we can expect more and more of these kinds of damaging events unless and until society has sharply reduced the amount of heat-trapping gases and particles(颗粒).”
【小题1】From paragraph 1 to paragraph 3, we learn ___________________________.
| A．what natural disasters mean to the people all over the world |
| B．how terrorism attacks struck in the past four decades |
| C．how the Earth struck back in 2010 |

You never see them, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to（易遭受）impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft.
Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1, 2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
【小题1】What information could be found from the black box on the Yemeni airliner?
| A．Data for analyzing the cause of the crash. |
| B．The total number of passengers on board. |
| C．The scene of the crash and extent of the damage. |
| D．Homing signals sent by the pilot before the crash. |
| A．New materials became available by that time. |
| B．Too much space was needed for its installation. |
| C．The early models often got damaged in the crash. |
| D．The early models didn't provide the needed data. |
| A．To distinguish them from the colour of the plane. |
| B．To caution people to handle them with care. |
| C．To make them easily identifiable. |
| D．To obey international standards |
| A．There is still a good chance of their being recovered. |
| B．There is an urgent need for them to be reconstructed. |
| C．They have stopped sending homing signals. |
| D．They were destroyed somewhere near Brazil. |

In a country that defines itself by ideals, not by shared blood, who should be allowed to come to work and live here? In the wake of the Sept．11 attacks these questions have never seemed more pressing．
On Dec．11, 2001, as part of the effort to increase homeland security, federal and local authorities in 14 states staged “Operation Safe Travel”---raids on airports to arrest employees with false identification．In Salt Lake City there were 69 arrests．But those captures were anything but terrorists, most of them illegal immigrants from Central or South America．Authorities said the undocumented workers’ illegal status made them open to blackmail（讹诈）by terrorists．
Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods．Mayor Anderson said those feelings were justified to a certain extent．“We’re saying we want you to work in these places, we’re going to look the other way in terms of what our laws are, and then when it’s convenient for us, or when we can try to make a point in terms of national security, especially after Sept．11, then you’re disposable．They are whole families being uprooted for all of the wrong reasons,” Anderson said．
If Sept．11 had never happened, the airport workers would not have been arrested and could have gone on quietly living in America, probably indefinitely．Ana Castro, a manager at a Ben & Jerry’s ice cream shop at the airport had been working 10 years with the same false Social Security card when she was arrested in the December airport raid．Now she and her family are living under the threat of deportation（驱逐出境）．Castro’s case is currently waiting to be settled．While she awaits the outcome, the government has granted her permission to work here and she has returned to her job at Ben & Jerry’s．
【小题1】How did the immigrants in Salt Lake City feel about “Operation Safe Travel”?
| A．Guilty | B．Offended | C．Disappointed | D．Discouraged |
| A．evidence was found that they were potential terrorists |
| B．most of them worked at airports under threat of terrorists |
| C．terrorists might take advantage of their illegal status |
| D．they were reportedly helping hide terrorists around the airport |
| A．there are other ways of enforcing the law |
| B．we will examine the laws in a different way |
| C．we will turn a blind eye to your illegal status |
| D．the existing laws must not be ignored |
