A dog’s tail can tell you a lot more than you might think. Is it wagging (摇) to the left or is it wagging to the right?
“The direction of tail wagging does in fact matter，”said Giorgio Vallortigara，a professor at the University of Trento in Italy. Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog’s state of mind—whether you’re a human or another dog.
What’s the difference between a left wag and a right wag？Professor Vallortigara and his colleagues have studied 43 dogs of various breeds — German Shepherds，Beagles，Boxers，Border Collies and some mutts. They find that if a dog wags its tail to the left. it’s feeling anxious or nervous. The reason could be an unfamiliar or dangerous situation，an unfamiliar person，or an unfamiliar and possibly threatening dog. But if the tail is wagging to the right，it means the dog is feeling relaxed and approachable.
“The tail is a very important signal，”said Thomas Reimchen，a biologist at the University of Victoria in British Columbia, Canada. ”There is a lot of visual information that dogs use when communicating with each other. ”
How did the scientists figure all this information out? They had the dogs in their study watch videotapes of other dogs. When the dog on the tape wagged its tail to the right，they say the other dogs remained calm and cool. But when the dog on the tape wagged its tail to the left，the other dogs got anxious.
The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously. They suspect that it might be something the dog does without even thinking about it — kind of like when you get goose bumps if something scares or startles you. They plan to do more research to get more information about what dogs are thinking and feeling while they’re wagging. As Reimchen said，“I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before. ”Professor Vallortigara’s study focused on the relationship between_________.

Early one morning the subinspector at a station at the other end of the town rang me. An elephant was damaging the town. Would I please come and do something about it?
I did not know what I could do, but I got onto a horse and started out. I took my gun, maybe too small to kill an elephant, but I thought the noise might scare him. Various local people stopped me on the way and told me about the elephant's doings.
It was not, of course, a wild elephant, but a tame one. It had been chained up but last night it had broken its chain and escaped. Its owner, had set out to run after it, but had taken the wrong direction. He was now twelve hours' journey away, and in the morning the elephant had suddenly appeared in the town. It had already destroyed somebody's bamboo hut (棚屋), killed a cow and turned over fruitstalls.
I came round the hut and saw a man's dead body sprawling in the mud. He was an Indian, and he could not have been dead many minutes. The people said that the elephant caught him with its trunk, put its foot on his back and grounded him into the earth. This was the rainy season and he was lying on his stomach in the soft mud, the__peacebreaker standing beside, looking innocent.
As I lifted my gun, I hesitated a few seconds. Then I fired. That was a shot that did for him.
You could see the pain of it knock the last strength from his legs. But in falling he seemed for a moment to rise, his trunk reaching skyward like a tree. He trumpeted, for the first and only time. And then down he came, with a crash that shook the ground.Which of the following statements about the author is TRUE?

Nowadays more and more people are trapped in too busy work to relax themselves. We have no time to tell a bed-time story to our children, or enjoy a nice dinner with our family, or take a break to think about how we live the precious life, or even meet friends. All we notice is that the distinctions that used to guide and steady us ------ between Sunday and Monday, public and private, here and there ------ are gone. We have more ways to communicate, but less and less to say. Partly because we’re so busy communicating.
Maybe that’s why more and more people I know, even if they have no religious commitment, seem to be turning to yoga, or meditation, or tai chi. Some friends of mine try to go on long walks every Sunday, or to “forget” their cellphones at home. A series of tests in recent years has shown that after spending time in quiet rural settings, subjects “exhibit greater attentiveness, stronger memory and generally improved cognition. Their brains become both calmer and sharper.” More than that, empathy, as well as deep thought, depends on neural processes that are “inherently slow. ” The very ones our high-speed lives have little time for.
In my own case, I turn to eccentric and often extreme measures to try to keep my sanity and ensure that I have time to do nothing at all. I’ve not yet used a cellphone and I’ve never Tweeted or entered Facebook. I try not to go online till my day’s writing is finished, and I moved from Manhattan to rural Japan.
None of this is a matter of principle or asceticism (苦行主义): it’s just pure selfishness. Nothing makes me feel better-----calmer, clearer and happier----than being in one place, absorbed in a book, a conversation, a piece of music. It’s actually something deeper than mere happiness: it’s joy, which the monk David Steindl-Rast describes as “that kind of happiness that doesn’t depend on what happens.” That is the highest of the highest we have been longing for----The Joy of Quiet.The writer sometimes doesn’t do anything because ________.
| A．he is out of work . |

| A．Somebody really forgets his cellphone at home. |
| B．Somebody thinks cellphone is not a suitable means of communication. |

| D．Somebody leaves his cellphone at home on purpose. |

Susan Sontag (1933----2004) was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything---to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s, publishing essays in such important magazines as Partisan Review, she appeared as the symbol of American culture life, trying hard to follow every new development in literature, film and art. With great effort and serious judgment, Sontag walked at the latest edges of world culture.
Seriousness was one of Sontag’s lifelong watchwords(格言),but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In Notes on Camp, the 1964 essay that first made her name, she explained what was then a little-known set of difficult understandings, through which she could not have been more famous. “Notes on Camp”, she wrote, represents “ a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’”.
By conviction（信念）she was a sensualist, but by nature she was a moralist, and in the works she published in the 1970s and 1980s , it was the latter side of her that came forward. In Illness as Metaphor —published in 1978, after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities, a concept that effectively blamed the victim for the disease. In fact, re-examining old positions was her lifelong habit.
In America, her story of a19thcentury Polish actress who set up a perfect society in California, won the National Book Award in 2000.But it was as a all-purpose cultural view that she made her lasting fame. “Sometimes,” she once said, “I feel that, in the end, all I am really defending …is the idea of seriousness, of true seriousness.” And in the end, she made us take it seriously too.The underlined sentence in paragraph 1 means Sontag_________.

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.
The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.Not enough sleep can cause obesity by ______.
| A．burning more of your energy |
| B．making you want to eat more food |
