Monkeys seem to have a way with numbers．
A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0﹣25 drops of water or juice as a reward． The researchers then tested how the monkeys combined﹣or added﹣the symbols to get the reward．
Here's how Harvard Medical School scientist Margaret Livingstone， who led the team， described the experiment： In their cages the monkeys were provided with touch screens． On one part of the screen， a symbol would appear， and on the other side two symbols inside a circle were shown． For example， the number 7 would flash on one side of the screen and the other end would have 9 and 8． If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice； if they went for the circle， they would be rewarded with the sum of the numbers﹣17 in this example．
After running hundreds of tests， the researchers noted that the monkeys would go for the higher values more than half the time， indicating that they were performing a calculation， not just memorizing the value of each combination．
When the team examined the results of the experiment more closely， they noticed that the monkeys tended to underestimate（低估）a sum compared with a single symbol when the two were close in value﹣sometimes choosing， for example， a 13 over the sum of 8 and 6． The underestimation was systematic： When adding two numbers， the monkeys always paid attention to the larger of the two， and then added only a fraction（小部分）of the smaller number to it．
"This indicates that there is a certain way quantity is represented in their brains， "Dr． Livingstone says． "But in this experiment what they're doing is paying more attention to the big number than the little one．"

Australian scientists say an organic compound(复合物) used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer.
Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma(黑瘤), a type of skin cancer. More than 1,200 Australians die every year from the disease.
Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment.
“We believe it works by getting into the tumor(肿块) cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It’s not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision(切除),”he said. “It’s useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred.”
About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal.
Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging.
Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg.
“I’ve had a lot of friends who just said ‘I thought it was just, you know, I’ll get a mole(痣) cut out and that’s it’, whereas I don’t think people realize how much danger they’re putting themselves into and how easy it is to stop something like this happening to you just from doing little things,”said Marock.
Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned(浅肤色的), are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.The information about Rose Bengal is wrong EXCEPT that.
| A．it is no longer used as a dye |
| B．it is used to cure skin cancer |
| C．it is a special kind of rose planted in Australia |
| D．it can be effective in treating skin cancer |
The main reason for Australia’s high rate in skin cancer is.
| A．the overuse of cosmetics |
| B．overexposure to the sun |
| C．the color of their skin |
| D．the lack of prevention |
From the passage we can learn that.
| A．skin cancer is incurable |
| B．some young people seem to know little about the danger of overexposure to the sun |
| C．about ninety percent of Australians are likely to develop melanoma |
| D．all moles should be cut out to prevent skin cancer |
According to Professor John Thompson, the best way to deal with primary cancer is .
| A．injecting tumors |
| B．taking some medicine |
| C．getting genetic treatment |
| D．having surgical excision |
The passage was intended for.
| A．general readers |
| B．people who like taking sun-bathing |

“Just take a deep breath.” “Don’t think about it.” “You’re more likely to die in a car wreck on the way to the airport than you are in a plane crash.” These are just some words given to people with a fear of flying. But as Tom Cruise, playing Lt. Daniel Kaffee in the movie A Few Good Men, said, “I get sick when I fly because I’m afraid of crashing into a large mountain. I don’t think Daniel will help.”
But there’s a new application that just may. Today, the VALK Foundation, a Dutch group that’s a partnership between KLM Royal Dutch Airlines and the University of Leiden, launches the app in the US. The VALK Foundation was one of the first centers for research and fear-of-flying treatment in the world and is the organizer of three world conferences on fear of flying.
The foundation said the app, called Flight App VALK, is the first scientifically-developed, web-based treatment for people who suffer from mild to moderate fear of flying.
“The fear of flying application we have created aims to transfer all of the knowledge we have developed through our program into a mobile application that will help ease travelers’ fears,” said Dr. Lucas van Gerwen, director of the VALK Foundation. Dr. van Gerwen is also a psychologist and professional pilot with more than 30 years experience.
The foundation said up to 30% of adults are fearful fliers. The Flight App is designed to help relax passengers before and during flights by educating users about flight safety and turbulence. It explains the sounds and sensations they can expect during departure, flight and landing. And, if a passenger’s flight stress reaches a panic level, they press a special panic button which provides audio and written information to help decrease stress levels. Most importantly, the Flight App can be used during the flight in the airplane mode. Once downloaded, the program does not require Internet connection in the air.By saying the words at the beginning of the passage, people are expected to ______.
| A．decrease their fear of flying |
| B．get rid of their doubt about plane |
| C．have a good time on their flight journey |
| D．use some medicine to cure their fear of flying |
Flight App VALK is aimed to ______.

According to the passage, the VALK Foundation ______.
| A．is a group focusing on psychology on the flight |
| B．was the first center to do research into fear of flying |
| C．organize the world conferences on fear of flying annually |

Folklore is the branch of the study of man which deals with local customs, tales and traditions. Everybody is a storehouse of folklore, though not everybody realizes it. Often, in deed, those who have never heard the word folklore have the greatest store of it, for the people with least book education commonly cherish most firmly old ideas and superstitions (迷信) which have been passed on by word of mouth for generations. Everyone has heard stories of ghosts, witches, fairies, and giants. We all know some proverbs and have come across such ideas as, for example, that it is lucky to see black cat and unlucky to see a single magpie (喜鹊). We keep certain seasons of the year as festivals, such as Christmas, and we are familiar with the special customs connected with weddings and funerals. All such things are of interest to those who study folklore.
People who study folklore won’t criticize the old beliefs and practices they come across as silly, childish, or old-fashioned. Instead, they will try to collect accurate records of them and then see how these are connected with other ideas and customs of other places or times. By comparing with what is known of olden times or the folklore of other countries, they try to discover how certain beliefs and practices came into being, and what purpose they serve now or used to serve in the past.
Often we find that the beliefs which seem most peculiar and unreasonable, and the customs which appear least practical, are of the greatest interest and importance because they are commonly the oldest. Sometimes they were part of an ancient ritual (惯例) or served a useful purpose when people’s way of life was different from what it is now. So we not only learn about what people thought and did in the past but are better able to understand present customs. People often keep up customs when they have forgotten the original reason for them, and in the course of time a fresh reason gets attached to the custom. Thus, when some joker ties an old shoe to the back of the taxi taking the bride and bridegroom to the station for their honeymoon, he would say it was “for luck”, but actually a shoe is an old fertility (繁殖力) symbol and has a place in the wedding customs of China and Palestine.The underlined word “they” (in Para.2) most probably refers to _________.
| A．practices and beliefs | B．customs and traditions |
| C．records and tales | D．places or times |
It is most unlikely for people who study folklore to _________.
| A．collect as many records of old beliefs and practices as possible |
| B．compare the present customs with those of the olden times |
| C．criticize the old beliefs and superstitions as silly or childish |
| D．find out the purpose the certain beliefs and practices serve or used to serve |
Which of the following statements is true about customs?
| A．The customs which do not appear practical mean nothing to most people. |
| B．The reasons for certain customs may change in the course of history. |
| C．People who practice customs are quite familiar with their origins. |
| D．The wedding customs in China and Palestine are of great similarity. |
What would be the best title for the passage?
| A．What Does Folklore Really Mean? |
| B．How Do People Keep Up Customs? |
| C．Who Studies Tales And Traditions? |
| D．When Did Some Old Beliefs Begin? |
Recently I spoke to some of my students about what they wanted to do after they graduated, and what kind of job prospects they thought they had.
Given that I teach students who are training to be doctors, I was surprised to find that most thought that they would not be able to get the jobs they wanted without “outside help”. “What kind of help is that?” I asked, expecting them to tell me that they would need a relative or family friend to help them out.
“Surgery(外科手术)”, one replied. I was pretty alarmed by that response. It seems that the graduates of today are increasingly willing to go under the knife to get ahead of others when it comes to getting a job. One girl told me that she was considering surgery to increase her height.“They break your legs, put in special extending screws, and slowly expand the gap between the two ends of the bone as it regrows, you can get at least 5cm taller!”
At that point, I was shocked. I am short, I can’t deny that, but I don’t think I would put myself through months of agony(痛苦) just to be a few centimeters taller. I don’t even bother to wear shoes with thick soles, as I’m not trying to hide the fact that I am just not tall! It seems to me that there is a trend toward wanting “perfection”, and that is an ideal that just does not exist in reality.
No one is born perfect, yet magazines, TV shows and movies present images of thin, tall, beautiful people as being the norm. Advertisements for slimming aids, beauty treatments and cosmetic surgery clinics fill the pages of newspapers, further creating an idea that “perfection” is a requirement, and that it must be purchased, no matter what the cost. In my opinion, skills, rather than appearance, should determine how successful a person is in his chosen career.We can know from the passage that the author works as ______.
| A．a doctor | B．a model | C．a teacher | D．a reporter |
.Many graduates today turn to cosmetic(美容） surgery to______.
| A．marry a better man\woman |
| B．become a model |
| C．get an advantage over others in job-hunt |
| D．attract more admirers |
According to the passage, the author believes that ______.
| A．everyone should purchase perfection, whatever the cost |
| B．it’s right for graduates to ask for others to help them out in hunting for jobs |
| C．media are to blame for misleading young people in their seeking for surgery |
| D．it is one’s appearance instead of skills that really matters in one’s career |
What does the author think of his height?
| A．He hates to be called a short man. |
| B．He tries to increase his height through surgery. |
| C．He always wears shoes with thick soles to hide the fact. |
| D．He just accepts it as it is |
We use both words and body language to express our thoughts and opinions and to communicate with other people. We can learn about what a person is thinking by watching his or her body language. Words are important, but the way a person stands, folds his or her arms, or moves his or her hands can also give us information about his or her feelings.
Just like spoken language, body language varies from culture to culture. Making eye contact —looking directly into someone’s eyes — is in some countries a way to show interest. In other countries, however, eye contact is rude or disrespectful. The gesture for Ok, making a circle with one’s thumb and index finger, has different meanings in different cultures. In Japan, someone who sees another person making the gesture will think it means money. In France, a person seeing the same gesture will think it means zero. In Brazil and Germany, however, the gesture is rude. The thumbs-up gesture, meaning “great” or “good job” in the US is rude in Nigeria, but in Germany and Japan it means the number one. The “crazy” gesture, moving the index finger in a circle in front of the ear, means “you have a phone call” in Brazil.
Even the gesture we use for “yes” and “no” are different around the world. In many countries, shaking one’s head means “no”, and nodding means “yes”. In Bulgaria, parts of Greece, and Iran, however, the gestures have the opposite meaning. There are also differences as to how often we touch each other, how close we stand to someone we are talking to, and how we act when we meet or part. In some countries, for example, France and Russia, a visiting friend is greeted with a kiss on the check, in other countries people greet each other with a firm handshake, a loving hug, a bow or a simply a nod of the head.
While there are many different interpretations of our body language, some gestures seem to be universal. Pressing one’s palms together and resting one’s head on the back of one’s hand while closing the eyes as if sleeping means “I am tired.” A good way of saying “I am full” is moving the hand in circles over the stomach after a meal. If a person pats his or her stomach before a meal, it usually means “ I’m hungry.”
Perhaps the best example of universally understood body language is the smile. A smile can help us get through difficult situation and find friends in a world of strangers. A smile can open doors and tear down walls. It can be used to express almost any emotion. We can use a smile to apologise, to greet someone, to ask for help or to start a conversation. We can smile at ourselves in the mirror to make ourselves feel happier and stronger. And if we are feeling down or lonely, there is nothing better than to see the smiling face of a good friend.In our daily life, which of the following do we use to communicate with each other?
| A．gestures | B．words | C．smiles | D．all above |
As a Chinese , if you are lost in Germany, without knowing German, you’d better---- to ask for help?
| A．use eye-contact | B．thumb-up |
| C．smile | D．say “excuse me” |
What does this passage mainly about?
| A．all the gestures in the world |
| B．the same body language in the world |
