The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned building, where up to 30% of the air is recycled.

解析试题分析：本文讲新型的建筑Eastgate,它比传统的建筑省钱，因为不需要装空调，它是利用天井和风扇把外面新鲜空气吸到办公室里面，这样空气即新鲜又经济。
【小题1】B 细节理解题。根据第二段提到The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size这个建筑物，用了传统建筑物尺寸的10%，全国最大的商业购物中心，意思所有的建筑物在同一个地方，所以选B项。
【小题2】D 细节理解题。根据第三段提到Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.可知新鲜空气一个通过通风口，另外当它上升变暖，最后通过被烟囱从天花板吸走，所以得知有两个途径，一通风口二烟囱，所以选D项。
【小题3】D 细节理解题。根据倒数第二段提到This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,得知只有一定海拔高度，并且白天的气温30度而夜晚气温14度的条件才能实现，而纽约的天气是近季节变化而不是天，所以D不是主要因素。
【小题4】A 细节理解题。根据最后一段提到It is found that the temperature of the building has generally stayed between 23℃ and 25℃, 除了 the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night得知建筑物内的温度保持在23到25度，除10月与11月的雨季之外。所 以选A项。
【小题5】D 主旨大意。本文讲新型的建筑Eastgate,它比传统的建筑省钱，因为不需要装空调，它是利用天井和风扇把外面新鲜空气吸到办公室里面，尤其是最后三段讲其是如何工作的，所以D项符合题意。

Around the world coral reefs(珊瑚礁) are facing threats(威胁) brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive(破坏性的) in the long run.
Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record.
During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death.
The coral’s ability to adjust to cool temperatures surprised the researchers, who say the study’s results show the complexities(复杂性) of monitoring coral health in response to different environmental factors(因素).
“Global warming is associated with increases but also decreases of temperatures,” said Deheyn, one of the researchers. “Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change.”
【小题1】Which of the following is TRUE according to the passage?
| A．Corals are unable to adjust to temperature changes. |
| B．Cold temperature causes greater damage to corals. |
| C．Hot temperature helps coral reefs to grow quickly. |
| D．Heat and cold damage corals in their own ways. |
| A．scientists used to pay no attention to the effect of cold events on corals |
| B．2010 witnessed one of the greatest temperature differences on record |
| C．corals prefer warmer conditions to cold temperatures in the long run |
| D．global warming has nothing to do with the decrease of temperature |
| A．corals may continue to grow in cold events after a few days |
| B．cold events help corals grow more quickly in a short time |
| C．corals show no response to hot temperatures in the first days |
| D．corals are whitened mainly because of warm temperatures |
| A．news report | B．scientific study | C．great imagination | D．natural conditions |

(2013·高考新课标全国卷Ⅱ，C)Given that many people’s moods (情绪)are regulated by the chemical action of chocolate，it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine.Looking like a setting from the film Charlie&the Chocolate Factory，Singapore’s Chocolate Research Facility (CRF) has over 100 varieties of chocolates.Its founder is Chris Lee who grew up at his parents’ corner store with one hand almost always in the jar of sweets.
If the CRF seems to be a smart idea，that’s because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi’s and Sony.That idea surely results in the imagination at work when it comes to making different flavored (味道) chocolates.
The CRF’s produce is “green ”，made within the country and divided into 10 lines，with the Alcohol Series being the most popular.The Exotic Series－with Sichuan pepper，red bean (豆)，cheese and other flavors－also does well and is fun to taste.And for chocolate_snobs，who think that they have a better knowledge of chocolate than others，the Connoisseur Series uses cocoa beans from Togo，Cuba，Venezuela，and Ghana，among others.
【小题1】What is good about chocolate?
| A．It serves as a suitable gift. |

Did anyone find the names of “Great Britain”, “the United Kingdom”, “England” and “the British commonwealth” which have the same meaning? Strictly speaking, these names all refer to something different. None of them are exactly the same as any of the others.
The British isles refer to the main islands and several thousand small ones as well, which you can see on the map. Great Britain, or Britain, refers to the larger of the two main islands. But the word “Britain” is often used as a short form for the United Kingdom or you call it the UK.
Now as for England, it refers simply to the largest of the three countries on the island of Great Britain. The United Kingdom is the name of the state and the official name of the country, which many people popularly refer to England.
Finally, the Britain commonwealth is the usual name for what is left of the British Empire (帝国). This change shows the weakening of British Empire and the rising of the national liberation movements throughout the world today.
【小题1】According to the passage, we know that _____________.
| A．Great Britain has the same meaning as Britain |

In most situations, light helps us see. But when it comes to looking at the night sky, light is actually a kind of pollution. It prevents our view of some of life’s most striking sights: stars, planets, and even galaxies(银河系).
“When I was a little boy, I loved the night sky. I remember looking up and the sky was filled with stars. I became an astronomer because I was amazed by their beauty,” says Robert Gent, “Now in most big cities kids can’t see the stars like I did.”
Normally, about 2,500 individual (单个的) stars are visible to the human eyes without using any special equipment. But because of light pollution, you actually see just 200 to 300 and fewer than a dozen from some cities. Only one in three Americans can see our own galaxy with the naked eyes. Those people live far away from the lights of big cities, office buildings, and shopping malls.
Fortunately, there’s an inexpensive and useful way. If we shine lights down at the ground instead of up into the sky, and use lower brightness levels, we can save big amounts of energy and keep the beauty of the night sky. Many cities and towns have passed laws limiting lights at night, making sure enough shine for safety without creating much light pollution.
Light pollution affects more than our view of the heavens and can harm wildlife. Migrating birds(候鸟) sometimes fly over cities and become confused by the brightness, flying in circles until they drop from exhaustion. Sea turtles need dark beaches for nesting and won’t approach bright lights. Too much light at night may even affect human health. For all these reasons, researchers are working on ways to use lights only when and where they are truly needed. Everyone deserves to look up at the sky.
【小题1】According to the text, using our naked eyes, ________.
| A．people in remote areas can see more stars than those in big cities |
| B．over one third Americans can see our own galaxy |
| C．about one in three Americans in big cities can see our own galaxy |
| D．Americans can only see 200 to 300 stars |
| A．save the electricity |
| B．make sure of migrating birds’ safety |
| C．let you count the number of stars |
| D．avoid much light pollution |
| A．The cause of light pollution. |
| B．The way to reduce light pollution. |
| C．The effect of light pollution. |
| D．People’s attitude towards light pollution. |
| A．air pollution | B．tiredness | C．breath | D．brightness |
| A．Light Pollution | B．Seeking the Sky | C．Stars in the Sky | D．City Pollution |

Every electronic gadget (小玩意) needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts.
Now, scientists in California say they have come up with a way to turn a living cell into a memory device.
It can store only one tiny bit of information, but it’s a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease.
Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can’t be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream.
If normal machines won’t do the trick, perhaps biology will. Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information.
This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive.
In the new experiment, the researchers turned DNA from bacteria(细菌) into a switch. They “flip (翻转)” a small section of DNA. Then, using the same procedure (过程) , the scientists flip the section again—returning it into its normal structure.
Using these DNA switches, “We can write and erase DNA in a living cell,” bioengineer, Jerome Bonnet, explained to Science News.
It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory—less than what a computer uses to remember a single letter.
“This was an important proof that it was doable,” Bonnet told Science News. “Now we want to build a more complex system, something that other people can use.”
【小题1】What is the aim of listing the electronic things in the first paragraph?
| A．To make the passage more fashionable. |
| B．To show how electronic things have memory. |
| C．To discuss things in detail. |
| D．To make the subject of the text more understandable. |
| A．To detect disease at the earliest point. |
| B．To help improve the memory. |
| C．To help people build a body. |
| D．To replace many electronic gadgets. |
| A．It has a very small memory. |
| B．It can function as a computer. |
| C．It has one letter in it. |
| D．It takes a day to complete it. |

Today, the biggest killers stem as much from our lifestyles as from bacteria and viruses. One of the worst of these is heart disease, and specifically high blood pressure. It’s a slow, but efficient killer that robs many people of what should be the last 10, 20 or 30 years of their lives.
Scientists are claiming that they have now separated unusual ingredients in a rare seaweed discovered by fishermen off the coast of Korea that offer incredible health benefits—including the ability to restore blood pressure to normal levels.
Dr. Haengwoo Lee, a famous biochemist conducted a clinical study on these two ingredients. The first is Seanol, an extremely rare seaweed extract(浓缩物) from Ecklonia Cava that's proven to be 100 times more powerful than any land-based antioxidant(抗氧化剂). That's because it stays working in your body for 12 hours, compared to land-based antioxidants that work for 30 minutes. "Its secret is its make-up of special chemicals that are a huge 40% fat soluble( 可溶的)," Dr. Lee explains. "Unlike nearly all land-based antioxidants that are water soluble, Seanol's protective compounds can get into things like the fatty tissues of your brain and penetrate（渗透） all three layers of your cells, including the outside, the oil-based cell membranes（细胞膜）, and your DNA." Indeed, Seanol is so powerful, it's the only FDA-approved Ecklonia Cava marine-algae (海藻) extract in existence.
The second ingredient is Calamarine, a deep-sea omega-3 discovery that delivers 85% more DHA omega-3s to your heart, brain, joints, and eyes. It's known to reduce the problems from tiredness and poor memory, joint pain, mood swings and depression.
With that research in mind, Dr. Lee combined Seanol and Calamarine with a high dose of vitamin D to form Marine-D3, the newest supplement in the fight against age-related illnesses and high blood pressure.
Dr. Lee found that Calamarine delivers some of the greatest concentration of omega-3s known to science. Combined with Seanol's ability to reduce body inflammation(炎症), as well as help cells get the nutrients they need to thrive, stay healthy and protected, Marine-D3 is able to boost a body's entire well being.
The makers of Marine-D3 are so confident that you'll see fast dramatic results from this product, that if you aren't happy after two full months, simply return the unused portion and they'll buy it back. They'll even give you ten dollars extra just for giving it an honest try! That kind of faith, combined with Dr. Lee's exhaustive research, shows that Marine-D3 really is a one-of-a-kind product.
【小题1】From the first paragraph we can infer that ________.
| A．Our lifestyles result from the biggest killers |
| B．our lifestyles do less harm to our bodies than bacteria and viruses do. |
| C．High blood pressure left untreated may cause shorter life. |
| D．Heart disease is incurable. |
| A．Fishermen off the coast of Korea have isolated unusual ingredients. |
| B．Scientists have purified ingredients that can lower blood pressure to normal standard. |
| C．Scientists discovered a rare seaweed. |
| D．Scientists have imagined a medicine that treat blood pressure. |
| A．According to FDA , Seanol reaches the agreed standard. |
| B．Seanol can be fat soluble entirely. |
| C．Seanol is a common seaweed extract fromEcklonia Cava. |
| D．Seanol's protective compounds can get into all things like the fatty tissues of your brain. |

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（装置）. 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(火星细菌) 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(万亿). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?
【小题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. |

Dogs wag(摇摆) 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.
【小题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 |
