A device that stops drivers from falling asleep at the wheel is about to undergo(接受) testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called driver Alert, aims to reduce deadly road accidents by 20%--40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to tiredness.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a sound about every four minutes during a car journey. After each sound the driver must respond by pressing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

Most summer camps for teens center around sports, or music and arts, or just for having fun. But some girls in the Washington suburb of Arlington County, Virginia, went to camp to get a taste of what its like to be a firefighter.
This is not a typical summer camp. But Michelle Pawlaw is glad she signed up for it."Getting to experience the fires hands-on is really cool and something that most people don't get to do," she said.
Michelle and eight other teenage girls are participating in the three-day camp offered by the Arlington County Fire Department located just outside of Washington.
“The purpose is to try to get young women interested in considering the fire service as a career” said firefighter Clare Burley, who is in charge of the program.
The free of charge, overnight camp is designed to let the girls experience what firefighters do in the line of duty to protect the community.
They take classes and learn how to climb the ladder on a fire truck, operate emergency tools and rescue on injured person. They also do their share of cleaning the firehouse and the equipment Firefighting is still a male-dominated (男性主导) service. Clare joined the department seven years ago, saying "We do everything that the guys do to the same standarD.We are tested to the same standarD.We are expected to operate at the same standard."
Most of the girls say they had never thought about becoming a firefighter, but the camp was a great learning experience.
"I think it is definitely not a job that only men can do. Women can do it just as well as men can," said Michelle Pawlaw.
'I think I can help other people if they need help and know what to do in case I am at a fire myself," said Kayla Ehrlich.
"I think it's fantastic; I could consider taking it as a career some day." said Monica Bartorsh.
And, the girls say, by spending three days together, they also made new friends and had a lot of fun.____might become a firefighter in the future.

A victim of climate change
A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the animal’s death.The starved polar bear in Norway was said to be in good health in April when the Norwegian Polar Institute examined and labeled it. However, the animal was reduced to skin and bones by the time a group of explorers came across its body in July.
The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals.
"From his lying position in death the bear appears to simply have starved and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone."
Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals. That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April.
Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change.
The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species.How did Stirling know the reason for the death of the polar bear?
A.By the food he ate |
B.By doing further experiments |
C.By observing other polar bears |
D.By his lying position in death |
The underlined word "vulnerable" probably means _____
A.easily hurt | B.difficult to hunt |
C.dangerous | D.amazing |
What is the author's attitude to the incident?
A.Favorable. | B.Uncaring |

Global Positioning Systems are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But they can also cause a lot of problems, sending you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two.
Barry Brown is with the Mobile Life Centre in Stockholm, Sweden. The center studies human-computer interaction, or HCI, especially communications involving wireless devices. We spoke to Mr. Brown by Skype. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay.
Barry Brown: “And they just plugged in an address and then set off to their destination. And, then it wasn’t until they were driving for thirty minutes that they realized they had put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of “garbage in garbage out”. Mr. Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment.
Barry Brown: “One problem with many GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”
Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people’s cars. They wrote a paper based on their research. It is called “The Normal, Natural Troubles of Driving with GPS.”
Barry Brown: “One of the things that struck us, perhaps the most important thing was that you have to know what you’re doing when you use a GPS. There are these new skills that people have developed. There are these new competencies that you need to have to be able to use a GPS because they sometimes go wrong.” Barry Brown says this goes against a common belief that GPS systems are for passive drivers who lack navigational (导航) skills.
“The Normal, Natural Troubles of Driving with GPS” lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues related to when GPS commands are given.
Barry Brown says to make GPS systems better we need a better understanding of how drivers, passengers and GPS systems work together.What is the best title for this passage?
A.Is GPS system reliable to use? | B.What is the use of GPS? |
C.How to make the most of GPS? | D.Blame! GPS or Passengers? |
What is the implication of the underlined part?
A.GPS is just a garbage device. |
B.GPS will not correct human errors. |
C.GPS adjusts your wrong destination. |
D.GPS is just as smart as human beings. |
Which is NOT mentioned as a GPS shortcoming in the passage?

C.Outdated maps. | D.Dear cameras GPS uses. |
According to the passage, people commonly believe that ___________.
A.you have to know where to go when using GPS |
B.you need to have new competencies to use GPS well |

“Image is everything.” An entire industry has been built upon the assumption that image is everything, but when it comes down to it, an appealing image is not enough. If there is no substance(事实)behind the image, the product, service or person will fail eventually.
First of all, one should consider how important image is in the selling of products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. Public concept of that product or service is certainly managed by the images created by the advertising agencies.But if the product or service does not live up to the image that was created, the customer will be very dissatisfied and possibly ask for their money back. For example, the Arthur Andersen accounting firm had spent decades building up an image of trustworthiness. But the recent scandal (丑闻) showed that behind that image, it cheated in business practices. Despite the previous positive image, the firm is being accused of criminal actions and it will probably not survive as a business unit. Although the image had been nearly perfect, the reality behind the image has led to the downfall of the world famous accounting firm.
Similarly, personal advisers can build up a public image for politicians and movie stars. Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons. But once again, history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close.
To summarize, it is clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation. What lies behind that image is every bit as important as the image itself —— the person or product must deliver on that image or there is little chance for long-term success.The downfall of the Arthour Andersen accounting firm is due to ___________.
A.its dishonesty in business | B.its previous images |
C.its bad management | D.its poor service |
Why did some famous people fall from grace?
A.Their images were not well built up. |
B.They failed to live up to their images. |
C.They felt much pressure from the public. |
D.They paid little attention to fame and fortune. |
The structure of the passage is ___________.
A: Argument P: Point C: ConclusionThe author tries to argue that ___________.
A.image creates everything |
B.image is the key to success. |
C.truth is unlikely ever to be equaled |
D.truth and image are equally important |
