The Vienna-based researchers showed that dogs will stop doing a simple task when not rewarded if another dog, which continues to be rewarded, is present．
The experiment consisted of taking pairs of dogs and getting them to present a paw for a reward．On giving this “handshake” the dogs received a piece of food．One of the dogs was then asked to shake hands, but received no food．The other dog continued to get the food when it was asked to perform the task．
The dog without the reward quickly stopped doing the task, and showed signs of anger or stress when its partner was rewarded．
To make sure that the experiment was really showing the interaction between the dogs rather than just the frustration of not being rewarded, a similar experiment was conducted where the dogs performed the task without the partner．Here they continued to present the paw for much longer．
Dr Frederike Range from the University of Vienna says this shows that it was the presence of the rewarded partner that was the greater influence on their behaviour．
“The only difference is one gets food and the other doesn’t, they are responding to being unequally rewarded．” she said．
The researchers say this kind of behaviour, where one animal gets frustrated with what is happening with another, has only been observed in primates(灵长类) before．
Studies with various types of monkeys and chimpanzees show they react not only to seeing their partners receiving rewards when they are not, but also to the type of reward．
The dog study also looked at whether the type of reward made a difference．Dogs were given either bread or sausage, but seemed to react equally to either．Dr Range says this may be because they have been trained．
57．The dogs refused to give the paw when they_______．
A．found another dog was given nothing
B．felt they were not treated equally
C．were aware they received less food
D．were given too much reward
58．What would the dogs do if they presented their paw alone?
A．They would go on with the performance much longer．
B．They would be too shy to present their paw．
C．They would miss their partners．
D．They would compare what they got with that of others．
59．According to the passage, compared with dogs, monkeys and chimpanzees ______．
A．pay no attention to the type of reward
B．only like to play interesting games
C．pay attention to the type of reward as well as whether they are rewarded
D．care more about how they are rewarded
60．Which of the following can best summerise the passage?
A．Animals’ various ways to show anger
B．Dogs are more envious than man
C．Most animals want to be be rewarded for their work
D．Animals also have a sense of fairplay
The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells.
As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla (香草), and unpleasant smells such as durians (榴莲). The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water.
Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change.
Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results.
One explanation is that women’s sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.Before the experiment, volunteers ______.
| A．are gathered and take a training |
| B．cannot eat or drink for several hours |
| C．must wash their hands carefully |
| D．will be interviewed by Dr Finkelstein |
If both men and women are asked to keep their hands in hot water while taking in some pleasant smells, ______.
| A．women may stand the pain of the hot water longer |
| B．men may keep their hands in the hot water longer |
| C．they will probably take their hands out at the same time |
| D．we are not quite sure who will take their hands out earlier |
From the passage we learn that _________.
| A．the reason why women are sensitive to smells is clear |
| B．the experiment for the sense of smell has come to an end |
| C．unpleasant smells affect men’s senses more than women’s |
| D．scientists have not totally explained the result of the study |
Now scientists believe that _______.
| A．mothers recognize their children only by sight |
| B．men’s sense of smell developed a long time ago |
| C．strong smells have a great influence on people’s senses |
| D．smells are helpful for mothers to spot their children |
The writer wrote the passage in order to ________.
| A．supply some entertainment to us |
| B．show women’s sharper senses than men’s |
| C．inform the readers of some knowledge |
| D．call for volunteers for the experiment |
A nine-year-old kid was sitting at his desk when suddenly there was a puddle (水坑) between his feet and the front of his trousers was wet. He thought his heart was going to stop because he couldn’t possibly imagine how this had happened. It had never happened before, and he knew that when the boys found out, especially Jack, he would never hear the end of it. When the girls found out, especially Martha and Jackie, they would never speak to him again as long as he lived.
He prayed this prayer, “Dear God, I need help now! Five minutes from now I’m dead meat!” He looked up from his prayer and here came the teacher with a look in her eyes that said he had been discovered. As the teacher was walking toward him, a classmate named Susie was carrying a goldfish bowl full of water. Susie lost her balance in front of the teacher and dumped (倒) the bowl of water in the boy’s lap. The boy pretended to be angry, but all the while was saying to himself, “Thank you, Lord!”
Now all of a sudden, instead of being the object of ridicule (嘲笑), the boy was the object of sympathy (同情). The teacher rushed him downstairs and gave him gym shorts to put on while his trousers dried out. All the other children were on their hands and knees cleaning up around his desk. Martha even gave him her own candy. The sympathy was wonderful. But as life would have it, the ridicule that should have been his had been turned to someone else—Susie. She tried to help, but they told her to get out.
When school was over, the boy walked over to Susie and whispered, “You did that on purpose, didn’t you?” Susie whispered back, “I wet my trousers once, too!”The underlined sentence in Paragraph 1 means _______.
| A．the boys would never play with him |
| B．the boys would treat him as usual |
| C．he would hardly hear any praise from the boys |
| D．he would be laughed at by the boys endlessly |
After Susie dumped water in his lap, the boy was in a state of _______.
| A．disappointment | B．relief | C．anxiety | D．anger |
What did the other kids do after the incident?
| A．They offered him dry clothes. |
| B．They laughed at the boy rudely. |
| C．They helped the boy do the cleaning. |
| D．They urged the boy to get out angrily. |
Why did Susie dump water in the boy’s lap?
| A．The boy asked her to do so. | B．She just did it by accident. |

Besides Susie, _______ also knows what had really happened to the boy.
| A．Martha | B．Jack | C．the teacher | D．the boys |
Photos that you might have found down the back of your sofa are now big business!
In 2005, the American artist Richard Prince’s photograph of a photograph, Untitled (Cowboy）, was sold for $ 1, 248, 000.
Prince is certainly not the only contemporary artist to have worked with so-called “found photographs”—a loose term given to everything from discarded(丢弃的） prints discovered in a junk shop to old advertisements or amateur photographs from a stranger’s family album. The German artist Joachim Schmid, who believes “basically everything is worth looking at”, has gathered discarded photographs, postcards and newspaper images since 1982. In his on-going project, Archiv, he groups photographs of family life according to themes: people with dogs; teams; new cars; dinner with the family; and so on.
Like Schmid, the editors of several self-published art magazines also champion (捍卫) found photographs. One of them, called simply Found, was born one snowy night in Chicago, when Davy Rothbard returned to his car to find under his wiper(雨刷） an angry note intended for some else: “Why’s your car HERE at HER place?” The note became the starting point for Rothbard’s addictive publication, which features found photographs sent in by readers, such a poster discovered in our drawer.
The whole found-photograph phenomenon has raised some questions. Perhaps one of the most difficult is: can these images really be considered as art? And if so, whose art? Yet found photographs produced by artists, such Richard Prince, may riding his horse hurriedly to meet someone? Or how did Prince create this photograph? It's anyone's guess. In addition, as we imagine the back-story to the people in the found photographs artists, like Schmid, have collated (整理）, we also turn toward our own photographic albums. Why is memory so important to us? Why do we all seek to freeze in time the faces of our children, our parents, our lovers, and ourselves? Will they mean anything to anyone after we've gone?
In the absence of established facts, the vast collections of found photographs give our minds an opportunity to wander freely. That, above all, is why they are so fascinating.The first paragraph of the passage is used to _________.
| A．remind readers of found photographs |
| B．advise reader to start a new kind of business |
| C．ask readers to find photographs behind sofa |
| D．show readers the value of found photographs |
According to the passage, Joachim Schmid _________.
| A．is fond of collecting family life photographs |
| B．found a complaining not under his car wiper |
| C．is working for several self-published magazines |
| D．wondered at the artistic nature of found photographs |
The underlined word "them" in Para 4 refers to __________.
| A．the readers | B．the editors |
| C．the found photographs | D．the self-published magazines |
By asking a series of questions in Para 5, the author mainly intends to indicate that ________.
| A．memory of the past is very important to people |
| B．found photographs allow people to think freely |
| C．the back-story of found photographs is puzzling |
| D．the real value of found photographs is questionable |
The author’s attitude towards found photographs can be described as _________.
| A．critical | B．doubtful | C．optimistic | D．satisfied |
In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity. Others say that competition is bad; that it sets one person against another; that it leads to unfriendly relationship between people.
I have taught many children who held the belief that their self-worth relied（依赖）on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit（追求）of success, the development of many other human qualities is sadly forgotten.
However, while some seem to be lost in the desire to succeed, others take an opposite attitude. In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: “ I may have lost, but it doesn’t matter because I really didn’t try.” What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of true competitors who try to prove themselves. Both are based on the mistaken belief that one’s self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve(缓解） can we discover a new meaning in competition.What does this passage mainly talk about?
| A．Competition helps to set up self-respect. |
| B．Opinions about competition are different among people. |
| C．Competition is harmful to personal quality development. |
| D．Failures are necessary experience in competition. |
Why do some people favor competition according to the passage?
| A．It pushes society forward. |
| B．It builds up a sense of duty. |
| C．It improves personal abilities. |
| D．It encourages individual efforts. |
The underlined phrase "the most vocal" in Paragraph 3 means __________.
| A．those who try their best to win |
| B．those who value competition most highly |
| C．those who are against competition most strongly |
| D．those who rely on others most for success |
What is the similar belief of the true competitors and those with a "desire to fail"?
| A．One's worth lies in his performance compared with others. |
| B．One's success in competition needs great efforts. |
| C．One's achievement is determined by his particular skills. |
| D．One's success is based on how hard he has tried. |
Which point of view may the author agree to?
| A．Every effort should be paid back. |
| B．Competition should be encouraged. |
| C．Winning should be a life-and-death matter. |
| D．Fear of failure should be removed in competition. |
Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.According to the passage, people are advised to take more Vitamin D, because__.
| A．it is nutritious | B．it can‘t harm people’s health |
| C．it can lower cancer risk | D．it is not taken enough every day |
Which of the following can not help people get more Vitamin D?
| A．Have some sunshine | B．Have more meat |
| C．Have more fortified cheese | D．Have a vitamin supplement |
Which of the following food can lower people‘s chance of getting cancer?
| A．Milk | B．Fortified orange juice | C．Fortified yogurt | D．All of the above |
