Has been a dream for 30 years but now the world’s first flying car is set to hit the roads this year. 
Ever since the “Back to the Future” movies lit up our screens in the 1980s, designers have dreamt of cars that could take to the sky at the push of a button(按钮). And now pilots can order their own “roadable” plane for just￡127, 000.
The plane, which has fold-out wings that span 17. 5 feet, can be up to 115 mph. Back on the land, it can also travel at “highway speeds” in car mode(模式).
Fuelling(加燃料)the 19 feet long plane couldn’t be simpler—you just drive it into a petrol station and fill it up.
A spokeswoman said, “You can keep your ‘light-sport airplane’ in your garage. But because it needs a short runway to take to the air, you will have to drive to your local airport, fly up to 460 miles, land and drive directly to your destination(目的地). You will always be ready to drive or fly. ”
The spokeswoman added, “Never let bad weather change your trip. You can simply divert(使转向)and continue on the ground until the weather clears. ”
There’s no risk to you—this is only the chance for you to be the first at your home field to unfold(展开)your wings and fly into the future.

Below is a selection from a popular science book.
If blood is red, why are veins（静脉）blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-up?
Baby (or “milk”) teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they’re gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine(脊柱)becomes shorter and more curved due to disuse and the effects of gravity（重力）. Many (but not all) men and women do lose height as they get older. Men lose an average of 3—4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy(眩晕的)?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But, when you suddenly stop spinning the system goes out control, and your brain thinks you’re moving while you’re not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area—from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animals on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.
【小题1】What is the colour of blood in a vein near the surface of the skin?
| A．Blue | B．Dark reddish purple |
| C．Red | D．Light yellow |
| A．Because their spine become more bent. |
| B．Because they are more easily affected by gravity. |
| C．Because they keep growing backwards. |
| D．Because their spine is in active use. |
| A．The brains of the other mammals are as complex as those of humans. |
| B．When our brain senses the spinning, we will feel dizzy. |
| C．In the long run, our brain probably works harder than our heart. |
| D．Our feelings and emotions come from the most developed area in our brain. |
| A．it takes four to five times as much blood to feed our brain as to feed our heart. |
| B．when adult teeth are gone, they cannot grow back. |

The forces that make Japan one of the world’s most earthquakeprone (有地震倾向的) countries could become part of its longterm energy solution.
Water from deep below the ground at Japan’s tens of thousands of hot springs could be used to produce electricity.
Although Japanese hightech companies are leaders in geothermal (地热的) technology and export it，its use is limited in the nation.
“Japan should no doubt make use of its resources of geothermal energy，” said Yoshiyasu Takefuji，a leading researcher of thermalelectric power production.
The disastrous earthquake and tsunami on March 11,2011 caused a reaction against atomic power，which previously made up 30 percent of Japan’s energy needs，and increased interest in alternative energies，which accounted for only 8 percent.
Artist Yoko Ono has called on Japan to explore its natural energy，following the example of Iceland which uses renewable energy for more than 80 percent of its needs.
For now，geothermal energy makes up less than 1 percent of the energy needs in Japan，which has for decades relied heavily on fossil fuels and atomic power.
The biggest problem to geothermal energy is the high initial cost of the exploration and constructing the factories.Another problem is that Japan’s potentially best sites are already being developed for tourism or are located within national parks where construction is forbidden.
“We can’t even dig 10 cm inside national parks.” said Shigeto Yamada of Fuji Electric，adding that regulations protecting nature would need to be relaxed for geothermal energy to grow.
Researcher Hideaki Matsui said，“Producing electricity using hot springs is a decadeslong project.We also have to think about what to do for now as energy supplies will decline in the short term.”
The Earth Policy Institute in Washington，US，believed Japan could produce 80 000 megawatts (兆瓦) and meet more than half its electricity needs with geothermal technology.
Japanese giants such as Toshiba are already global leaders in geothermal technology，with a 70 percent market share.In 2010，Fuji Electric built the world’s largest geothermal factory in New Zealand.
【小题1】What would be the best title for the text?
| A．Alternative energies in Japan |
| B．World’s largest geothermal plant |
| C．Japan takes the lead in geothermal technology |
| D．Japan thinks of geothermal energy |
| A．About 8%. | B．Below 1%. |
| C．Around 30%. | D．Over 80%. |
| A．a change of rules | B．financial support |
| C．local people’s help | D．high technology |
| A．Yoshiyasu Takefuji | B．Hideaki Matsui |
| C．Shigeto Yamada | D．Yoko Ono |
| A．the world’s biggest geothermal plant was built by America |
| B．Japan will not export its geothermal technology |
| C．the potential of Japan’s geothermal energy is great |
| D．it is hard to find geothermal energy in Japan |

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or whether people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over-looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower? Probably not—it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
【小题1】The whole passage is mainly about .
| A．predictions that have come true |
| B．predictions that haven’t come true |
| C．why predictions don’t come true easily |
| D．what technology will bring about |
| A．predictions needn’t consider people’s practical use of technology |
| B．the future isn’t always easy to guess |
| C．not all past predictions have come true |
| D．many of the high-tech things our parents thought we’d be using by now simply never appeared |
| A．wonderful | B．stupid |
| C．practical | D．strange |
| A．It is too difficult to imagine. |
| B．It is too crazy an idea. |
| C．It is likely to be made. |
| D．It is often reported in the news. |

Ten years ago, with only about 1, 000 pandas left in the world, China was desperately trying to clone(克隆)the animal and save the endangered species(物种). That was a move similar to what Texas A & M University researchers had been undertaking for the past five years in a project called “Noah’s Ark”(诺亚方舟).
Noah’s Ark was aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, said there would be enough of the basic building blocks to reintroduce the species in the future. 
It was estimated that as many as 2, 000 species of mammals, birds reptiles would become extinct in over 100 years. The panda, native only to China, was in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They were then trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nucleus transfer(核子移植)of one species to another is not easy, and the lack of available(capable of being used)panda eggs could be a major problem,”Kraemer believed. “They will probably have to do several hundred transfers to result in one pregnancy(having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, ”added Kraemer, who was one of the leaders of the project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed. ”
At present, the project has worked. The number of the pandas has increased to more than 1, 500.
【小题1】The aim of “Noah’s Ark” project was to .
| A．make efforts to clone the endangered pandas |

Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life.
Blue/Purple
Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants (抗氧化剂) that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight.
A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer.
Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc.
Green
We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer.
Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene （胡萝卜素）. Diets high in those above are associated with lowered blood pressure."
Foods that contain the green color are: broccoli, cabbage, cucumbers, etc.
Red
Lycopene (番茄红素) in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks.
Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce."
Foods that contain red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc.
Orange
The orange foods are also rich in carotene, which are particularly good antioxidants. These foods are commonly considered eyesight foods because they contain vitamin A.
"Orange fruits and vegetables also play a part in preventing cancer, particularly of the lungs and stomach. Foods that contain the color orange are: Carrots, mangoes, sweet potatoes, pumpkins, etc.
【小题1】The passage tries to tell us that ______.
| A．colors mean a lot to people and their health |
| B．foods of different colors will have different benefits |
| C．eating foods with a color must prevent diseases |
| D．what people should eat in their daily lives |
| A．lowering blood pressure | B．improving eyesight |

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmosphere CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. “We’ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we’ve been able to record this increasing quantity of atmosphere CO2 into the ocean.”
Scientists expected that as atmosphere CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves in the water or seawater in this case, it forms a weak acid, carbonic acid,” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic.”
The seawater samples Dore and his colleagues have analyzed confirm what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It’s important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic.”
【小题1】What can be the best title of the passage?
| A．Scientist Researching Seawater |
| B．Sea Life Facing Danger |
| C．Oceans Becoming More Acidic |
| D．Climate Change Affecting Seawater |
| A．more corals will appear in the sea |
| B．the chemical balance of the seawater is affected |
| C．the surface water is becoming warmer |
| D．the pH of the ocean out here has been increasing |
| A．a→b→c→d→e | B．e→b→c→d→a |
| C．a→e→b→c→d | D．e→d→c→b→a |
| A．the expectation of other scientists |
| B．some former theory |
| C．his research and analysis |
| D．a major cause of climate change |

Taking a picture of your tongue with a mobile phone could soon instantly tell you how healthy you are. Researchers believe the images can reveal important information about a patient’s health and even give them early warning of serious illness.
A team at the University of Missouri is developing a system that can analyze pictures using a 5,000-year-old Chinese principle, which is based on the flow and balance of positive and negative energies in the body, and uses the tongue as a key to learning about a person’s physical health, or “zheng” according to Chinese medicine.
“Within a year, our goal is to create an application for smart phones that will allow anyone to take a photo of their tongue and learn the status of their zheng,” said Dong Xu, chair of MU’s Computer Science Department in the College of Engineering and the co-author of the latest study.
The software analyzes images based on the tongue’s color and coating to distinguish between tongues showing signs of “hot” or “cold” zheng. Shades of red and yellow are associated with hot zheng, whereas a white coating on the tongue is a sign of cold zheng.
“Hot and cold zheng doesn’t refer directly to body temperature,” said Xu, “Rather, it refers to a series of symptoms associated with the state of the body as a whole.”
For the study, 263 gastritis(胃炎) patients and 48 healthy volunteers had their tongues analyzed. The gastritis patients were classified by whether they showed infection by a certain bacteria as well as the intensity of their gastritis symptoms. In addition, most of the gastritis patients had been previously classified with either hot or cold zheng. This allowed the researchers to test the accuracy of the software’s analysis.
“Our software is able to classify people based on their zheng status. And as we continue to work on the software we hope to improve its ability,” said another co-author Ye Duan, “Eventually everyone will be able to use this tool at home using webcams or smart phone applications, which will allow them to monitor their zheng and get an early warning about possible ailments.”
【小题1】 The software mentioned in the passage is based on ________.
| A．the latest development of smart phones |
| B．a traditional Chinese medical principle |
| C．the changes in one’s flow and energy |
| D．symptoms related with the state of the body |
| A．one’s body temperature | B．the physical health of a person |
| C．the possible disease of a person | D．the color and coating of one’s tongue |
| A．the effect of the software |
| B．the software’s great prospect |
| C．the advancement of smart phones |
| D．the greatness of Chinese medicine |
| A．analysis | B．effects | C．illnesses | D．applications |
| A．the software still needs improvement |
| B．the subjects in the study are all gastritis |
| C．the software has been in market for a year |
