It is not unusual for people to speak two or three languages; they’re known as bilinguals or trilinguals. Speakers of more than three languages are known as polyglots. And when we refer to people who speak many languages, perhaps a dozen or more, we use the term hyper-polyglot.
The most famous hyper-polyglot was Giuseppe Mezzofanti, a 19th century Italian cardinal, who was said to speak 72 languages. This claim sounds absurd. If you assume each language had 20,000 words, Mezzofanti would have to learn a word a minute, six hours a day, for eleven years—an impossible task. But Mezzofanti was tested by critics, and they were all impressed.
Did Mezzofanti have an extraordinary brain? Or are hyper-polyglots just ordinary people with ordinary brains who manage to do something extraordinary through hard work?
U.S. linguist Stephen Drashen believes that outstanding language learners just work harder at it and then they acquire unusually strong language ability. As an example, he mentions a Hungarian woman who worked as an interpreter during the 20th century. When she was 86, she could speak 16 languages and was still working on learning new languages. She said she learned them mostly on her own, reading fiction or working through dictionaries or textbooks.
Some researchers argue to the contrary. They believe that there is such a thing as a talent for learning languages. In the 1930s, a German scientist examined parts of the preserved brain of a hyper-polyglot named Emil Krebs, who could speak 60 languages fluently. The scientist found that the area of Krebs’s brain called Broca’s area, which is associated with language, looked different from the Broca’s area in the brains of men who speak only one language. However, we still don’t know if Krebs was born with a brain ready to learn dozens of languages or if his brain adapted to the demands he put on it.
Although it is still not clear whether the ability to learn many languages is in born, there’s no doubt that just about all of us can acquire skills in a second, third, or even fourth language by putting our mind to it.

Life on Mars could become a reality and it could happen in your lifetime.
A welcoming planet
Scientists say Earth’s neighbor Mars, a bright red planet about half Earth’s size, is the most likely to support human life. Mars even has frozen water on its surface.
Since the late 1990s, NASA has been exploring Mars using remote-controlled vehicles(裝置). Most recently Curiosity, a car-size vehicle, traveled through space on an unpiloted spacecraft(航天器) and landed on Mars in August 2012. Directed by NASA scientists , the vehicles move on the surface, taking pictures , collecting and analyzing soil, and looking for signs of life.
But what about human explorers? Plans are already in the works to send astronauts to Mars as soon as the mid-2030s.
_____________________________________
But before you start packing your bags, let’s consider the challenges. For starters, Mars is far away. Just getting there could take up to 10 months.
Scientists already know that time away from Earth’s gravity harms the human body. Bones and muscles get weaker. The body produces less blood. What damage would months and months of living in space do?
And then there is the matter of water, oxygen, food and fuel. Scientists will have to find solutions to these problems, or the first humans on Mars won’t survive very long in their new home.
Tiny Dangers
There’s another tinier risk. It’s so tiny that you can’t even see it: germs.
Some scientists believe that our germs could pollute the whole planet of Mars. Potentially killing Martian life before we have the chance to discover it. Worse, there is a small but terrifying chance that any microscopic life already there might be harmful to us .
Worse still, if any of those Martian germs(火星細(xì)菌) were brought back to Earth, the result could be disastrous. Animals, plants, and people could be wiped out.
Worth the $$$?
A more practical concern is the cost. The price could approach $ 1 trillion(萬億). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?
【小題1】Which of the following is TRUE according to the “A welcoming planet” part?
A.Mars is a little bigger than Earth. |
B.There are flowing rivers on Mars. |
C.People haven’t been to Mars so far. |
D.Scientists have discovered signs of life on Mars. |
A.Living in space. | B.Limited resources. |
C.Extreme conditions. | D.Interesting challenges. |
A.there is no serious danger |
B.people won’t be in any danger |
C.it’s difficult for people to realize the danger |
D.the danger may be caused by very small things |
A.Martian germs may be different from those on Earth. |
B.Martian germs may be brought back to Earth. |
C.People may carry germs to Mars. |
D.There may be germs on Mars. |
A.People | B.History | C.Science | D.Business |

Dogs wag(搖擺) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli(刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Ban University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive experience—their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.
【小題1】.The video cameras were used to catch the dogs’ responses because ___________ .
A.it was easier to catch the dogs’response changes in the tail wagging |
B.the dogs were put in the wooden boxes and tested one at a time. |
C.they enabled the dogs’owners to know about their dogs’habit |
D.the dogs wagged their tails in different directions when they were in different moods |
A.surprise | B.worry | C.excitement | D.interest |
A.wag to the left | B.wag to the right |
C.not wag at all | D.wag to the left and then to the right |
A.the dogs | B.the trainers | C.the systems | D.the rescarchers |
A.to train dogs for their owners | B.to help people judge the mood of dogs |
C.to help dogs find company | D.to help people choose their pet dogs |

A regular drop in the sun’s radiation(輻射) can cause unusually cold winters in parts of North America and Europe, scientists say, a finding that could improve long-range forecasts and help countries prepare for snowstorms.
Scientists have known for a long time that the sun has an 11-year cycle during which radiation measured by sunspots on the surface reaches a peak then falls. But explaining a clear connection to weather is harder.
“Our research confirms the observed connection between solar change and regional winter climate,” lead author Sarah Ineson of the UK Met Office told the reporters in an email. The study was published in the magazine Nature Geoscience on Monday.
The researchers found that the reducing of ultraviolet(UV,紫外線) radiation from the sun can affect high-altitude wind patterns in the Northern Hemisphere(半球), causing cold winters.
“While UV levels won’t tell us what the day-to-day weather will do, they show us the bright future of improved forecasts for winter conditions for months and even years ahead. These forecasts play an important role in long-term possibility planning,” Ineson, a climate scientist, said.
Ineson and colleagues from Imperial College London and the University of Oxford used satellite data that more accurately(精確的) measures UV radiation from the sun and found a much greater change than previously thought.
They found that in years of low activity, unusually cold air forms high in the atmosphere over the tropics. This causes a redistribution(重新分配) of heat in the atmosphere, making easterly winds that bring freezing weather and snowstorms to northern Europe and the United States and milder weather to Canada and the Mediterranean.
When solar UV radiation is stronger, the opposite occurs.
More study was needed, though. A key uncertainty in the experiment lay in the satellite data used, because it covers only a few years. “So questions remain concerning both accuracy(精確) and also applicability to other solar cycles,” she said.
【小題1】The new finding claims cold winters in the North Hemisphere can be caused by ______.
A.a(chǎn) sharp rise in the amount of sunspots |
B.a(chǎn) drop in the sun’s UV radiation |
C.a(chǎn) complex computer model simulation |
D.a(chǎn) clear link between the sun and the earth |
A.UV radiation can affect high-altitude wind patterns |
B.there’s a clear connection between the sun’s activity and weather |
C.the sun’s radiation reaches a peak every eleven years |
D.they can predict day-to-day weather conditions from UV levels |
A.Canada and the Mediterranean will have milder weather. |
B.The whole Northern Hemisphere will suffer from extreme winter days. |
C.Freezing cold weather will appear in northern Europe. |
D.Burning hot weather will appear in the United States. |
A.researchers have analyzed the data collected in eleven years |
B.long-term weather conditions can be accurately predicted depending on UV levels |
C.the research doesn’t seem correct and true enough due to limited satellite data used |
D.climate scientists have just begun their research in severe weather forecast |

Everyone may all have the experience of feeling anxious and stressed when having a rough day or having some troubles. Different people may choose different ways to deal with it, and for most people a break for a 10-minute walk may be quite useful.www.zxxk.com
Anyway, here is another way around: to get a piece of chewing gum, and chew it. According to a Swinburne University of Technology study, gum-chewing has been found to “relieve anxiety, improve alertness(機(jī)敏性) and reduce stress among individuals in a laboratory setting.”
Some may argue that a laboratory is not the same as an office. But check out the conditions of the study: individuals were monitored while performing “a group of ‘multi-tasking’ activities.” Doesn’t it sound like the situation in the office?www.zxxk.com
Here’s a summary of some of the study’s findings:
Gum chewers showed a reduction in anxiety as compared to non-gum chewers by nearly 17 percent during mild stress and nearly 10 percent in appropriate stress.
Gum chewers showed improvement in alertness over non-gum chewers by nearly 19 percent during mild stress and 8 percent in moderate stress.
Improved Performance: Chewing gum resulted in a big improvement in overall performance on multi-tasking activities.
Although these aren’t major improvements, every little bit works and chewing a piece of gum is a lot quicker and easier than slipping outside for a 10-minute walk. So, how does gum work this magic? In part it does so by lowering the level of cortisol(皮質(zhì)醇)—a steroid(類固醇) hormone that is released in response to stress in your system.
A few words of advice before you reach for the gum: don’t crack your gum, and be sure to chew it with your mouth closed. In fact, I’d say keep the gum out of meetings, because it really looks impolite to others around you.
【小題1】From the study in the text we know that_________________.
A.gum chewers may lack alertness |
B.gum chewers tend to be less stressed |
C.gum chewers can finish many jobs perfectly |
D.gum chewers can reduce their anxiety and anger easily |
A.It works by improving alertness. |
B.It works by allowing a 10-minute walk. |
C.It works by reducing one’s level of cortisol. |
D.It works by being chewed in a laboratory setting. |
A.People should chew gum with their mouths closed in a meeting. |
B.It is impolite to chew gum in a meeting with people around you. |
C.People can crack gum freely when meeting friends. |
D.People should be careful when chewing gum at home. |
A.How to chew gum. | B.How to relieve stress. |
C.Why people love chewing gum. | D.Chewing gum can relieve stress. |

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affect sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels(分貝)measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
【小題1】According to the passage, which of the following is increasingly dangerous to sea creatures?
A.The man-made noises. |
B.The noises made by themselves. |
C.The sound of earthquakes. |
D.The sound of the ice-breaking. |
A.They are deaf to noises. |
B.Noises at a certain level may hurt them. |
C.They are easily confused by noises. |
D.Noises will limit their ability to reproduce. |
A.prevent them from doing their research work |
B.benefit them a lot in their research work |
C.do good to their health |
D.increase the industrial output |
A.They will try their best to decrease noise. |
B.They will work hard to cut down noise pollution. |
C.They will study the effect of different noises. |
D.They will protect animals from harmful noises. |

Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland(瑞士)and China, built by the government(政府)to help some of the people live during a great war.
But will people change if they live under the ground for a long time?For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals(化學(xué)制劑)in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone?
【小題1】People will live under the ground because _________.
A.it’s neither hot nor cold there |
B.they’ll be afraid of the war |
C.there’ll be less space on the ground |
D.they’ll make their life comfortable |
A.when summer comes |
B.when a war breaks out |
C.because they think it’ll be safer for them |
D.when they’re fed up with the life on the land |
A.There’ll be enough light under the ground |
B.It’ll be easy to go upstairs |
C.Glasses will be sold under the ground |
D.Medicine will be supplied for free |
A.the world are polluted |
B.it’s dark there |
C.the air is dirty and there are a lot of chemicals in their food |
D.they can’t grow their own food in the sun |

China needs to set absolute restrictions on greenhouse gas emissions(釋放) if it is to fulfill its aim to set up a carbon market over the next five years, a cabinet office think tank said in a paper.
“It is only under an absolute emissions cap that carbon emission permits will become a scarce resource and possess the qualities of a commodity,” the State Council?s Development and Research Center said in a paper in Seeking Truth, a magazine published by the ruling party.
China has traditionally baulked(猶豫) at the idea of emissions caps either on a regional basis or for industrial sectors, invoking a key Kyoto protocol principle that puts most of the burden of cutting green-house gases on developed countries.
China, the world ‘s biggest emitter of greenhouse gases, has also been under external pressure to make stronger commitments in the battle against global warming .The country has been the biggest beneficiary(受益人) of the Clean Development Mechanism, a UN-backed scheme that allows industrialized countries to meet their CO2 reduction targets by purchasing certified emission reductions or CERs from low-carbon projects launched in developing nations.
However, the European Union, the biggest buyer of CERs, has said it will not accept CERs generated by Chinese projects once the first phase of its Emissions Trading Scheme ends in 2012, though projects already registered will remain valid.
【小題1】 What does China hope to do in the next five years?
A.to cut its emissions by 45% |
B.to set up a carbon market |
C.to have lower emissions than other countries |
D.to increase both emissions and production |
A.they care about the environment |
B.emissions harm people’s health |
C.of pressure from other countries |
D.they want more profit for their factories |
A.Countries can buy the right to produce as much carbon emissions as they like. |
B.All countries are required to set a carbon emissions cap and can then get certificates on how developed their environmental programme is. |
C.Developed countries are allowed to produce more emissions than industrial countries. |
D.Developed countries can buy the right to produce more carbon emissions from developing countries that produce less. |
A.Air pollution is still increasing the problem of climate change all over the world. |
B.China is still resisting cutting emissions as it is necessary for the manufacturing industry. |
C.China believes that it is free from meeting international standards on emissions. |
D.China will need to cut its emissions in the near future in order to keep up with the international community |

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
【小題1】We can infer from the text that humans and animals ____.
A.depend on one sense in choosing food |
B.a(chǎn)re not satisfied with their food |
C.choose food in similar ways |
D.eat entirely different food |
A.A white butterfly. | B.A small bird. |
C.The bear. | D.The fox. |
A.the season changes |
B.the food color changes |
C.they move to different places |
D.they are attracted by different smells |
A.food is chosen for a good reason |
B.French and British food is good |
C.some people have few choices of food |
D.some people care little about healthy diet |
A.Why choosing the right food is important. |
B.How to choose the right food. |
C.The right amount of food for a person. |
D.Vegetables matter more than meat and sugar. |
