Article: New security camera can "see" through clothes New technology that can " see " through clothing and detect what ' s underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places. The Thru Vision T5000 camera picks up Terahertz rays, or T-rays, which are naturally sent out by all objects and can pass through clothes or even walls. The camera can then detect metallic and nonmetallic objects hidden under clothing on still or moving objects without showing any body detail. While similar technology is seen at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding bottle-necks at border crossing or security checkpoints. It also means people can be screened without knowing it. The technology develops from British astronomers' work in studying dying stars. Astronomers use T-ray cameras to see through dust and clouds in space. The company sees uses for its camera at other sites where political or business activities take place. For privacy concerns,Thru Vision Chief Executive Clive Beattie said the image produced by the camera did not show detailed parts of the body. " It's almost a shining light bulb ." Beattie said. "You don' t see the detail that people might be concerned about. " In London' s busy Piccadilly Circus--which is already filled with closed -circuit surveillance cameras-- reaction to the new technology was mixed. Some said the camera was going too far and violating privacy,but others said they are willing to put safety before privacy concerns. " There ' s surveillance everywhere anyway." said one commuter. "I don' t think it' s much of a difference. I don' t care that they can see through me because they can see me anyway." Some experts said the privacy violation of the camera was not worth the benefit. " What we should consider is how much we want to lose our privacy in order to obtain a sort of national security," said David... Question: What can we learn about T5000? Options: A: It can detect metallic and nonmetallic objects underneath. B: It can see through clothing or walls by sending out T-rays. C: It was first used to observe stars by astronomers. D: It is widely used at airports around the world.

Read the article and select the best answer. Article: The Labrador has won the honor of the most popular breed for the past eighteen years. It has been described as gentle, clever and friendly. Yet not all Labs are the same. John Grogan discovered _ after he and his wife adopted a Labrador that they named Marley. The dog caused Mr. Grogan a lot of trouble, but it also provided many stories for his newspaper articles. Later, he wrote a best-selling book, "Marley and Me: Life and Love with the World's Worst Dog." Marley was happy and fun-loving. But he was also extremely large and difficult to control. He bit anything that he could find around the house, including plastic, clothing and jewelry. And he had a great fear of loud noises, especially thunderstorms. Unfortunately, the Grogans lived in Florida where many thunderstorms develop. Marley would attack the furniture, walls and doors until his feet bled if he was left alone in the house during a thunderstorm. Marley almost damaged their home several times. John Grogan said that at first he considered that probably his dog could be trained to be a show champion. But he soon realized that was impossible. Marley didn't like to learn skills that didn't belong to dogs, and he was driven out of the dog training school for causing troubles for other dogs. He didn't want to hide his emotions. He would show his anger and tiredness if he felt them. Even if that, Marley still had earned a place in the Grogans'. He didn't know how to dance, and he didn't know how to walk on its two legs, but he was what he was. He would never be a Lassie or a Benji or an old Yeller for he would never like to take part in a dog show, but the Grogans accepted him and loved him very much. Question: What made Marley attack the furniture when he was left alone in the house during a thunderstorm? Options: A: The fear of hearing loud noises. B: The anger of being left alone. C: The unhappiness of having no toys. D: The disappointment of getting nothing to eat.

Q: Read the article and select the best answer. Article: To whom it may concern, This letter describes the worst travel experience I have ever had.The problems we had were the result of poor management and thoughtless employees.Your airline should be ashamed of treating its customers so poorly. On January 5, we arrived in Denver from Houston and checked in for our next flight.It wasn't long before the agent announced that our flight would be delayed because of a mechanical problem. The equipment was in Aspen, and they expected it to be repaired soon. Soon shortly turned to much later, and during the delay, weather temporarily closed the Aspen airport.The weather cleared in Aspen and the plane took off very late for Denver.While it was in the air, the agent announced that the plane would be used for the next flight and that our flight was being cancelled. This cancellation struck me as being unfair.There was a mad scramble as the 50 or so passengers scheduled for our flight fought for seats on later flights.When the dust settled, we were wait-listed on the 9'-00 flight the next morning.We had to spend the night in the airport. Coming home was no better.Because of a mechanical problem, it looked like we would miss our connection in Denver.The agent assured us they would hold the Newark flight for us.Needless to say, the flight to Houston taxied out as we pulled into the gate.Arrangements were made for us to take the next flight, so we sat in the airport for 5 hours.When we finally arrived in Houston, our skis were missing.As of this writing, the skis have not been found. Nothing you can do will make us feel better about our flights.If you are a responsible business, however, you will do what you can to see that passengers in the future are treated better.
