Pete Richards was the loneliest man in town on the day that little Jean Grace opened the door of his shop.
Pete's grandfather had owned the shop until his death. Then the shop became Pete's. The front window was full of beautiful old things: jewelry of a hundred years ago, gold and silver boxes, carved figures from China and Japan and other nations.
On this winter afternoon, a child stood there, her face close to the window. With large and serious eyes, she studied each piece in the window. Then, looking pleased, she stepped back from the window and went into the shop. Pete himself stood behind the counter. His eyes were cold as he looked at the small girl. “Please,” she began, “would you let me look at the pretty string of blue beads in the window?” Pete took the string of blue beads from the window. The beads were beautiful against his hand as he held the necklace up for her to see.
“They are just right,” said the child as though she were alone with the beads. “Will you wrap them up in pretty paper for me, please? I've been looking for a really wonderful Christmas present for my sister.”
“How much money do you have?” asked Pete.
She put a handful of pennies on the counter. “This is all I have,” she explained simply. “I've been saving the money for my sister's present.”
Pete looked at her, his eyes thoughtful. Then he carefully closed his hand over the price mark on the necklace so that she could not see it. How could he tell her the price? The happy look in her big blue eyes struck him like the pain of an old wound.
“Just a minute,” he said and went to the back of the shop. “What's your name?” he called out. He was very busy about something.
“Jean Grace,” answered the child.
When Pete returned to the front of the shop, he held a package in his hand. It was wrapped in pretty Christmas paper.
“There you are,” he said. “Don't lose it on the way home.”
She smiled happily at him as she ran out of the door. Through the window he watched her go. He felt more alone than ever.
Something about Jean Grace and her string of beads had made him feel once more the pain of his old grief. The child's hair was as yellow as the sunlight; her eyes were as blue as the sea. Once upon a time, Pete had loved a girl with hair of that same yellow and with eyes just as blue. And the necklace of blue stones had been meant for her.
But one rainy night, a car had gone off the road and struck the girl. After she died, Pete felt that he had nothing left in the world except his grief. The blue eyes of Jean Grace brought him out of that world of self-pity and made him remember again all that he had lost. The pain of remembering was so great that Pete wanted to run away from the happy Christmas shoppers who came to look at his beautiful old things during the next ten days.
When the last shopper had gone, late on Christmas Eve, the door opened and a young woman came in. Pete could not understand it, but he felt that he had seen her before. Her hair was sunlight yellow and her eyes were sea-blue. Without speaking, she put on the counter a package wrapped in pretty Christmas paper. When Pete opened the package, the string of blue beads lay again before him.
“Did this come from your shop?” she asked.
Pete looked at her with eyes no longer cold. “Yes, it did,” he said.
“Are the stones real?”
“Yes. They aren't the best turquoise(绿松石), but they are real.”
“Can you remember to whom you sold them?”
“She was a small girl. Her name was Jean. She wanted them for her sister's Christmas present.”
“How much were they?”
“I can't tell you that,” he said. “The seller never tells anyone else what a buyer pays.”
“But Jean has never had more than a few pennies. How could she pay for them?”
“She paid the biggest price one can ever pay,” he said.
For a moment there was no sound in the little shop. Then somewhere in the city, church bells began to ring. It was midnight and the beginning of another Christmas Day.
“But why did you do it?” the girl asked.
Pete put the package into her hands.
“There is no one else to whom I can give a Christmas present,” he said. “It is already Christmas morning. Will you let me take you to your home? I would like to wish you a Merry Christmas at your door.”
And so, to the sound of many bells, Pete Richards and a girl whose name he had not yet learned walked out into the hope and happiness of a new Christmas Day.When Pete saw Jean Grace, he was ______.

Rene Descartes’ explanation of pain has long been acknowledged in medicine. He proposed that pain is a purely physical phenomenon – that tissue injury makes specific nerves send a signal to the brain, causing the mind to notice pain. The phenomenon, he said, is like pulling on a rope to ring a bell in the brain. It is hard to overstate how deeply fixed this account has become. In medicine, doctors see pain in Descartes’ terms— as a physical process, a sign of tissue injury.
The limitations of this explanation, however, have been apparent for some time, since people with obvious injuries sometimes report feeling no pain at all. Later, researchers proposed that Descartes’ model be replaced with what they called the gate control theory of pain. They argued that before pain signals reach the brain, they must first go through a gating mechanism in the spinal cord(脊髓). In some cases, this imaginary gate could simply stop pain signals from getting to the brain.
Their most amazing suggestion was that what controlled the gate was not just signals from sensory nerves but also emotions and other “output” from the brain. They were saying that pulling on the rope need not make the bell ring. The bell itself—the mind— could stop it. This theory led to a great deal of research into how such factors as mood, gender, and beliefs influence the experience of pain. In a British study, for example, researchers measured pain threshold and tolerance levels in 53 ballet dancers and 53 university students by using a common measurement: after immersing your hand in body-temperature water for two minutes to establish a baseline condition, you put your hand in a bowl of ice water and start a clock running. You mark the time when it begins to hurt: that is your pain threshold. Then you mark the time when it hurts too much to keep your hand in the water: that is your pain tolerance. The test is always stopped at 120 seconds, to prevent injury.
The results were striking. On average female students reported pain at 16 seconds and pulled their hands out of the ice water at 37 seconds. Female dancers were almost three times as long on both counts. Men in both groups had a higher threshold and tolerance for pain, but the difference between male dancers and male nondancers was nearly as large. What explains that difference? Probably it has something to do with the psychology of ballet dancers—a group known for self-discipline, physical fitness, and competitiveness, as well as by a high rate of chronic(慢性) injury. Their driven personalities and competitive culture evidently accustom them to pain. Other studies along these lines have shown that outgoing people have greater pain tolerance and that, with training, one can reduce one’s sensitivity to pain.
There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain. In one study of 500 patients undergoing dental procedures, those who were given a placebo(安慰剂) injection and promised that it would relieve their pain had the least discomfort— not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work.
Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bell on a string. Today every medical textbook teaches the gate control theory as fact. There’s a problem with it, though. It explains people who have injuries but feel no pain, but it doesn’t explain the reverse, which is far more common— the millions of people who experience chronic pain, such as back pain, with no signs of injury whatsoever. So where does the pain come from? The rope and clapper are gone, but the bell is still ringing.The primary purpose of the passage is to .
| A．describe how modern research has updated an old explanation |
| B．support a traditional view with new data |
| C．promote a particular attitude towards physical experience |
| D．suggest a creative treatment for a medical condition |

| A．The brain can shut pain off at will. |
| B．The brain plays no part in the body’s experience of pain. |

| D．Pain is an automatic response to bodily injury. |
The author implies that the reason why the gate control was “amazing” was that it .
| A．offered an extremely new and original explanation |
| B．was just opposite to people’s everyday experiences |
| C．was grounded in an ridiculous logic |
| D．was so sensible it should have been proposed centuries before |
The author refers to “chronic back pain” as an example of something that is .
| A．costly, because it troubles millions of people |
| B．puzzling, because it sometimes has no obvious cause |

Tayka Hotel De Sal
Where: Tahua, Bolivia
How much: About $95 a night
Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt—including the beds (though you’ll sleep on regular mattresses(床垫) and blankets). The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.
Green Magic Nature Resort
Where: Vythiri, India
How much: About $240 a night
Why it’s cool: Ridding a pulley(滑轮)-operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window—there is no glass!—you watch monkeys and birds in the rain forest canopy. Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don’t even have to come down for breakfast—the hotel will send it up on the pulley-drawn “elevator”.
Dog Bark Park Inn B&B
Where: Cottonwood, Idaho
How much: $92 a night
Why it’s cool: This doghouse isn’t just for the family pet．Sweet Willyis a 30-foot-tall dog with guest rooms in his belly. Climb the wooden stairs beside his hind leg to enter the door in his side.

Tensions have erupted over some barren rocks in the Pacific that you may never have heard of, but stay tuned—this is a boundary dispute(争端) that could get ugly and some day have far-reaching consequences for China, Japan, Taiwan and the United States.
The islands in dispute are called the Senkaku chain by Japan, the Diaoyu islands by China, and the Diaoyutai by Taiwan. All three claim the islands, which are really just five small islands and three barren rocks northeast of Taiwan, 200 miles off the Chinese coast.
The latest conflict occurred when a Chinese fishing boat collided(碰撞) with two Japanese naval ships trying to stop it near the islands. The Japanese prevented the Chinese captain from leaving the place for questioning and the two countries have been exchanging angry protests.
The reason to worry is that nationalists in both China and Taiwan see the islands as unquestionably theirs and think that their government has been weak in claiming this authority.
So far, wiser heads have generally won the argument on each side, but at some point a weakened Chinese leader might try to gain the legal right with the public by pushing the issue and recovering the islands. It would be a dangerous game and would have a disastrous impact on China-Japan relations, but if successful it would raise the popularity of the Chinese government.
In reality, of course, there is zero chance that the U.S. will honor its treaty(条约) with Japan over a few barren rocks. We're not going to risk a nuclear conflict with China over some islands that may well be China's. But if we don't help, our security relationship with Japan will be at the breaking point.
So which country has a better claim to the islands? My feeling is that it's China, although the answer isn't clear-cut. Chinese navigational records show the islands as Chinese for many centuries, and a 1783 Japanese map shows them as Chinese as well. Japan purported to “discover” the islands only in 1884 and took control of them by force only in 1895 when it also grabbed Taiwan.
The best approach would be for China and Japan to agree to refer the dispute to the International Court of Justice, but realistically that won't happen. And since some believe that the area is rich with oil and gas reserves, the claims from each side have become more insistent.
As Chinese nationalism grows, as China's navy and ability to project power in the ocean gains, we could see some military conflicts over the islands.
Taken from NewYork TimesThe underlined word “purported” (in Para.7) is closest in meaning to “_____”.
| A．happened | B．claimed | C．pretended | D．intended |
