However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, "How much do I owe you？" "You don't owe me anything," she replied. "Mother has taught me never to accept pay for a kindness. "He said," Then I thank you from the bottom of my heart. "As Howard Kelly left that house, he not only felt stronger physically, but it also increased his faith in the human race. He was about to give up and quit before this point. Years later the young woman became critically ill. The local doctors were baffled. They finally sent her to the big city, where specialists can be called in to study her rare disease. Dr. Howard Kelly, now famous was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went down through the hospital hall into her room. Dressed in his doctor's gown he went in to see her. He recognized her at once. He went back to the consultation room and determined to do his best to save her life. From that day on, he gave special attention to her case. After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the final bill to him for approval. He looked at it and then wrote something on the side. The bill was sent to her room. She was afraid to open it because she was positive that it would take the rest of her life to pay it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words... "Paid in full with a glass of milk." (Signed) Dr. Howard Kelly Tears of joy flooded her eyes.

The technique, described in the journal, Nature, uses a thermal camera to detect sudden, involuntary shifts of blood flow in the face. The system performed as accurately as a traditional polygraph, the scientists report. Yet the camera can provide answers instantly, and does not require a highly trained specialist to operate it or interpret its results. This makes it far better suited than the polygraph for a new, high-tech approach to security that is already raising the hackles of civil libertarians: the screening of large numbers of citizens, at airports and other sensitive areas, who have done nothing wrong. "The next decade is going to see the development of truly accurate lie detectors," said Stephen M. Kosslyn, an expert on detecting lies and a professor of psychology at Harvard University. The prototype, built by researchers at the Mayo Clinic and Honeywell Laboratories in Minnesota, is at least 2 years from being ready for general use. But other scientists said the discovery of previously unknown physiological changes in the face was itself an important step forward. "This is potentially very important work, which may open a new window on the mind," said Kosslyn. Pushed by technological advances, and with fresh interest, since Sept. 11, the discovery is part of a boom in the scientific study of deceit and its detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new approaches that might replace the polygraph, from brain scans, to subtle changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding, though, is remarkable for its simplicity. When a person tells a lie, the team found, there is a sudden rush of blood to the area around the eyes, according to the Mayo Clinic's Dr. James A. Levine. Although the change is not: ordinarily visible, the blood warms the skin, causing hands of color to appear through a camera sensitive to heat. The team devised a computer program that can identify the telltale changes based on the camera images. In testing at the US Department of Defense Polygraph Institute, which trains federal polygraph examiners, the device performed better than polygraphs, with 85 percent accuracy compared with 70 percent for the polygraph. Compared with a traditional polygraph a thermal camera ______. A．can show accurate results B．can easily be handled by anybody C．is a high-tech approach to security D．is used to fight against terrorism 此题为多项选择题。

Magellan sailed from Seville in August 1519 with five ships and about 280 men. Fourteen months later, after spending the severe winter on the coast of Patagonia, he discovered the channel which is now called Magellan's Straits. In November 1520, after many months of dangers from rocks and storms, the three remaining ships entered the ocean on the other side of South America. They then continued, hoping to reach Asia. Before they arrived at these islands, later known as the Philippines, Magellan was killed in battle. The remaining officers then had to get back to Spain. They decided to sail around Africa. After many difficulties, one ship with eighteen men sailed into Seville three years after leaving. They were all that remained of Magellan's expedition. However, their achievement was great. They were the first men to sail round the world. The purpose of Magellan's expedition was ______. A．to become famous at that time B．to find navigation line from the Atlantic to the Pacific C．to make a voyage to Asia D．to carry men to the Seville

A.not to be polluted B.against polluting C.from polluting D.from being polluted

In America, nearly 10 million children and teenagers visit virtual worlds regularly, estimates eMarketer, a market researcher-a number the firm expects to increase to 15 million by 2013．As in January, there were 112 virtual worlds designed for under-18s with another 81 in development, according to Engage Digital Media, a market research firm. All cater to different age groups and tastes. In Club Penguin, the market leader, which was bought by Disney in 2007 for a whopping $ 700 million, primary-school children can take on a penguin persona, fit out their own igloo and play games. Habbo Hotel, a service run from Finland, is a global hangout for teenagers who want to customise their own rooms and meet in public places to attend events. Gala Online, based in Silicon Valley, offers similar activities, but is visited mostly by older teens who are into Manga comics. Not a hit with advertisers, these online worlds earn most of their money from the sale of virtual goods, such as items to spruce up an avatar or a private room. They are paid for in a private currency, which members earn by participating in various activities, trading items or buying them with real dollars. This sort of stealth tax seems to work. At Gala Online, users spend more than $1 million per month on virtual items, says Craig Sherman, the firm's chief executive. Running such a virtual economy is not easy, which is why Gaia has hired a full-time economist to grapple with problems that are well known in the real world, such as inflation and an unequal distribution of wealth. There are other barriers that could limit the growth of virtual worlds for the young, but the main one is parents. Many do not want their offspring roaming virtual worlds, either because they are too commercial or are thought to be too dangerous. Keeping them safe is one of the biggest running costs, because their sponsors have to employ real people to police their realms. Youngsters are also a fickle bunch, says Simon Levene of Accel Partners, a venture- capital firm. Just as children move from one toy to another, they readily switch worlds or social networks, often without saying goodbye. Even so, Debra Aho Williamson, an analyst at eMarketer, believes "these worlds are a training ground for the three-dimensional web". If virtual worlds for adults, which so far have been able to retain only hardcore users, manage to hang on for a few years, they may yet have a second life. In the first paragraph it says that "Several have even found a way to make money" Which of the following could possibly be the "way" ？ A．Sales of the copies of the game. B．Sales of virtual goods in the game. C．Sales of game peripheral goods, such as dolls and OST CDs. D．Development of different games towards gamers of different ages.

A、takes out B、runs out C、makes out D、works out
