Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water,you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the groun.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes itunderground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水層) into which heat several heat exchangers (交換器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.

解析試題分析:最簡單方法往往很有效。城市里既然有了巨大的“深色”表面,為什么不用來收集太陽能呢?荷蘭工程師 Arian de Bondt 就發(fā)明了這樣一個系統(tǒng),用于在城市道路上收集太陽熱量,以便儲存加熱地底的水,還可以在冬季使用。
【小題1】細(xì)節(jié)理解題。根據(jù)“ But why go to all that trouble when cities are full of black surfaces already,
in the form of asphalt (柏油) roads?”可知柏油路也可以用來收集熱量。故選D。
【小題2】細(xì)節(jié)理解題。由“The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. ”可知潛水管的作用是把熱量傳導(dǎo)到下面的儲水層里。故選D。
【小題3】細(xì)節(jié)理解題。由“After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.”可知這個系統(tǒng)不僅僅是可以給建筑物供暖,還可以防止道路結(jié)冰積雪。故選B。
【小題4】推理判斷題。文章最后一段講了冬天如何供暖,所以后面要講這個系統(tǒng)在夏天如何為建筑物冷卻的工作方法。故選C。

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. “Today we’re looking at science fiction becoming tomorrow’s reality—the driverless car.” The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the US government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
“Cars have become much more fuel-efficient, and new electronic features are making Hondas safer,” said Angie Nucci of Honda America. “A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes.” Other safety features include warning systems on the front and the sides of the cars. These systems help drivers, but don’t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
“By taking out drivers, you also remove most risks of an accident,” Kendall said. He said consumers, however, may be unwilling to lose control. “It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first.”
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
【小題1】What can we learn from Paragraph l?
A. Volvo will be the first to sell driverless cars.
B. Driverless cars are pointing us a faraway future.
C. Driverless vehicles are now legal in the whole USA.
D. Google’s self-driving cars have covered a long distance.
【小題2】We learn that Governor of California Jerry Brown_________.
A.helped design self-driving cars |
B.supports self-driving cars on roads |
C.considers self-driving cars science fiction |
D.improved the self-driving car systems |
A.They are not allowed to run on the road. |
B.Their technical problems remain to be solved. |
C.They are now too expensive for consumers. |
D.They are more dangerous for people on the street. |
A.The Benefits of the Self-driving Cars |

Europe is now the biggest market for organic food in the world, having grown by 25 percent a year over the past 10 years. Denmark’s agriculture minister is herself an organic farmer. The UK market for organic food grew by 55 percent in 2000, while the food market as a whole grew by only one percent. Yet only seven percent of British shoppers account for nearly 60 percent of organic sales. However popular the idea of organic farming may be, it is still an interest for only a few people.
So what makes the idea of organic farming popular? Organic farming means farming with natural materials, rather than with man-made fertilizers or pesticides(殺蟲劑). Organic farmers rely on many methods — such as crop rotation (農(nóng)作物的輪作) and the use of resistant(有抵抗力的)varieties, because they are necessary for organic farmers to compensate for the shortage of man-made chemicals.
Organic farming is often supposed to be safer than traditional farming for the environment. Yet after a long research on organic farming worldwide for a number of years, science continues to be against this opinion. The House of Commons committee on agriculture stated that, even with complete research work, it would fail to find any scientific evidence to prove “that any of claims made for organic farming is always true”.
However, the talk about the benefits of organic farming is going on. This is partly because many people depend on their individual farm, the soil, the weather, and so on.
【小題1】The first paragraph mainly tells us _________.
A.organic farming has been performed only in Europe over the past 10 years. |
B.governments of European countries have cared less about organic farming. |
C.organic farming isn’t so popular as expected. |
D.European countries need organic food more than the other countries in the world. |
A.a(chǎn)rgue for | B.care for |
C.make up for | D.pay for |
A.It refers to farming with natural materials, instead of chemical fertilizers. |
B.It refers to farming with chemical fertilizers rather than natural fertilizers. |
C.It refers to farming with soil rather than any other thing. |
D.It refers to growing crops with man-made fertilizers and pesticides. |
A.organic farming is safer than traditional farming for the environment. |
B.the idea that organic farming is safer has not been proven by science. |
C.organic farming is accepted by the UK’s House of Commons committee. |
D.organic farming is preferred to traditional farming. |
A.The UK’s agriculture minister is an organic farmer. |
B.Organic farming is popular with young people. |
C.Farmers try every means to improve the organic sales system. |
D.Ninety-three percent of British shoppers don’t buy organic products. |

Below is a selection from a popular science book.
If blood is red, why are veins(靜脈)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(眩暈的)?
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.
【小題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. |
C.the reason why spinning make us dizzy. |
D.how we can grow taller. |

All of us eat every day, but most of us don’t understand nutrition(營養(yǎng)). How much do you know about good nutrition? Are the following statements true or false?
1. People who don’t eat meat can stay healthy.
True. As long as people eat enough milk, eggs and meat alternates(替代物), they can get enough protein.
2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.
False. The difference depends more on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water can lose a large quantity of vitamins.
3. Food eaten between meals can be just as good for health as food eaten at regular meals.
True. Nutritional value depends on what types of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.
4. Taking extra vitamins beyond the recommended daily allowances won’t give you more energy.
True. It’s widely believed that extra vitamins provide more energy. But taking more than the baby needs doesn’t make it function better, just as overfilling your gas tank doesn’t make your car run better.
5. Natural vitamins are better supplements(補充)for the diet than synthetic vitamins.
False. There is no difference. A vitamin has the same properties(性質(zhì))and specific chemical structure whether made in a laboratory or taken from plant or animal parts.
6. Older people need the same amount of vitamins as younger people.
True. Older people need the same quantity of vitamins as younger people although they need fewer calories. Certain illnesses raise the requirements for some vitamins, but that is true for the young as well as the old.
7. Food grown in poor soil is lower in vitamins than food grown in rich sold.
False. The vitamins in our foods are made by the plants themselves. They don’t come from the soil.
However, the minerals in a plant depend on the minerals in the soil.
If you have answered these questions correctly, you can say you know much about food and nutrition by today’s standards. But remember that nutrition is a growing science and that may be aged as new information is obtained.
【小題1】The main purpose of the passage is to .
A.list today’s standards of some food and nutrition |

Passenger pigeons(旅鴿)once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群)so large that they darkened the sky for hours.
It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered(驅(qū)散)the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.
【小題1】In the 18th and early 19th centuries, passenger pigeons _______.
A.were the biggest bird in the world |
B.lived mainly in the south of America |
C.did great harm to the natural environment |
D.Were the largest population in the US |
A.escape | B.ruin | C.liberation | D.evolution |
A.To seek pleasure. | B.To save other birds. |

How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.
【小題1】Which is one of the feature of the Kolibree toothbrush?
A.It can sense how users brush their teeth. |
B.It can track users’ school performance. |
C.It can detect users’ fear of seeing a dentist. |
D.It can help users find their phones. |
A.You will find it enjoyable to see a dentist. |
B.You should see your dentist on a day-to –day basis. |
C.You can brush with the Kolibree as if guided by a dentist. |
D.You’d like a dentist to watch you brush your teeth every day. |
A.It can be used to update mobile phones. |
B.It can be used to play mobile phone games |
C.It can send messages to other users |
D.It can talk to its developers. |
A.How Serval found out his kids lied to him. |
B.Why Serval thought brushing teeth was necessary. |
C.How Serval taught his kids to brush their teeth. |
D.What inspired Serval to invent the toothbrush |
A.They were unwilling to brush their teeth |
B.They often failed to clean their toothbrushes. |
C.They preferred to use a toothbrush with a dry head. |
D.They liked brushing their teeth after Serval came home. |
A.The brush handle will be removed. |
B.A mobile phone will be built into it. |
C.It will be used to fill holes in teeth |
D.It will be able to check users’ teeth |

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(物種). 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”(諾亞方舟).
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.
【小題1】The aim of “Noah’s Ark” project was to .

C.qualified researchers | D.enough money |
A.China’s Success in Pandas Cloning |
B.The First Cloned Panda in the World |
C.Exploring the Possibility to Clone Pandas |
D.China—the Native Place of Pandas Forever |
A.Kraemer and his team had succeeded in cloning a dog |
