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.”

Cyberspace,data superhighway,multimedia,for those who have seen the future,and the linking of computers,televisions and telephones will change our lives for ever.Yet for all the talks of a forthcoming technological utopia,little attention has been given to the implications of these developments for the poor.As for all the new high technology,the West concerns itself with the “how”,while the question of “for whom” is put aside once again.
Economists are only now realizing the full extent to which the communication revolution has affected the world economy.Information technology allows the extension of trade across geographical and industrial boundaries,and transnational corporations take full advantage of it. Terms of trade and exchange, interest rates and money movements are more important than the production of goods.The electronic economy made by information technology allows the haves to increase their control on global markets — with a destructive impact on the have-nots.
For them the result is unstable. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine. As “futures” are traded on computer screens, developing countries simply have less and less control of their destinies.
So what are the options of regaining control？One alternative for developing countries is to buy in the latest computers and telecommunications. Yet this leads to long-term dependency and perhaps permanent constraints on developing countries’ economies.
Communication technology is generally exported from the US, Europe or Japan；the patents, skills and ability remain in the hands of a few industrialized countries. It is also expensive, therefore imported products and services must be bought on credit usually provided by the very countries whose companies stand to gain.
【小题1】 From the passage we know that the development of high technology is in the interests of________.
| A．the rich countries | B．scientific development |
| C．the local elites | D．the world economy |
| A．international trade should be expanded |
| B．the interests of the poor countries have not been given enough consideration |
| C．the exports of the poor countries should be increased |
| D．communication technology in developing countries should be modernized |
| A．Because it enables the developed countries to control the international market. |
| B．Because it destroys the economic balance of the poor countries. |
| C．Because it violates the national boundaries of the poor countries. |
| D．Because it inhibits the industrial growth of developing countries. |
| A．hinder their industrial production |
| B．cause them to lose control of their trade |
| C．force them to reduce their share of exports |
| D．cost them their economic independence |
| A．positive | B．critical |
| C．indifferent | D．tolerant |

The world's largest solar thermal plant(太阳热能发电站)is set to begin producing power in the United States by the end of the year. Wind and energy from the sun are generally considered clean, unlike energy from coal-burning power stations. However, environmentalists now worry that too much solar power development could harm the local environment.
A California company — BrightSource Energy is building a huge solar power plant in the Mojave desert, about 60 kilometers southwest of Las Vegas, Nevada. The plant is known as the Ivanpah Solar Electric Generating System. Joe Desmond works for the company. "This is actually one of the highest concentrations of sunlight in the world, out here in Ivanpah." explained Desmond. BrightSource Energy will deploy 170,000 specially designed mirrors to direct solar energy towards boilers on top of three power towers. The steam produced in the boilers will drive turbine (涡轮) to make electricity. Joe Desmond says the steam can reach temperatures of more than 260 degrees Celsius. "We can store the sun's thermal energy in the form of molten salt, so we can produce electricity even when the sun goes down. There is a lot of interest in concentrating solar power around the globe in environmnents where you have lots of sun, such as China, South Africa, the Middle East, North Africa, explained Desmond.
Environmentalists generally support the idea of solar power, however, many are concerned about the effect of power plants on sensitive environment. Lisa Belenky is a lawyer with the Center for Biological Diversity, a private group. She says environmentalists are specifically worried about the effect of the Ivanpah Solar Project on the sensitive plant and animal life in that part of Mojave desert. "Even though the desert seems big, when you start cutting it up, it can really affect how the species and the animals and the plants are able to survive in the long run,"said Lisa Belenky. BrightSource Energy has already spent more than $ 50 million to move endangered desert tortoises away from the power plant. but Lisa Belenky says this is not the answer. "We should be reusing areas that have a1ready been disturbed, like old mining sites, for example...either on homes, on businesses, parking lots." said Belenky.
There have also been reports of birds dying at the Ivanpah Plant and others like it.
Some birds die after colliding with solar equipment which the animals mistake for water. Other birds were killed or suffered burns after flying through the intense heat at the solar thermal plant. As solar projects increase, environmentalists and developers are considering what to do to reduce bird death.
【小题1】Why is the Ivanpah Solar Electric Generating System being built in the desert?
| A．Because the temperature is extremely high in the desert. |
| B．Because there is no life in the desert. |
| C．Because there is much salt in the desert. |
| D．Because sunlight is highly focused in the desert. |
| A．Because the sun's thermal energy can be stored in the form of steam. |
| B．Because the sun's thermal energy can be stored in the form of molten salt. |
| C．Because the sun'ss thermal energy can be stored through mirrors |
| D．Because the sun's thermal energy can be stored in the boilers. |
| A．supportive | B．critical | C．indifferent | D．cautious |

One might expect that the evergrowing demands of the tourist trade would bring nothing but good for the countries that receive the holidaymakers. Indeed, a rosy picture is painted for the longterm future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rockbound Pacific island is advertised as the ‘last paradise(天堂) on earth’．
However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of seaside holidays, overcrowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holidaymakers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The onetime farmer is now the servant of some multinational organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.
Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning worldwide tourism can preserve the market for these companies. If not, in a few years' time the very things that attract tourists now may well have been destroyed.
【小题1】What does the author indicate in the last sentence of Paragraph 1?
| A．The Pacific island is a paradise. |
| B．The Pacific island is worth visiting. |
| C．The advertisement is not convincing. |
| D．The advertisement is not impressive. |

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection. [来源:学,科Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement（侵犯）. Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties（版税）. In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
【小题1】Barthelemy Thimonnier’s garment factory was burned down because _____________.
| A．people did not know how to put out the fire |
| B．Elias Howe thought Thimonnier had stolen his invention |
| C．the sewing machines was couldn’t work finally |

| C．The foot treadle helped to make the sewer’s hands free. |
| D．Singer made improvements to the design of sewing machines. |
| A．Because the judge was against Singer for his surly attitude. |
| B．Because Howe had already patented the lockstitch used by Singer. |
| C．Because Singer had borrowed money from Howe and never repaid it. |
| D．Because Singer and Howe had both invented the same machine. |
| A．A Stitch in Time Saves Nine |
| B．The Case between Howe and Singer |

Expensive and new gloves allow chatterboxes（话匣子）to take the term “handsfree” to a new level—by talking into them as they make a call. The gloves are known as “Talk to the Hand” and cost £1,000 a pair. They fixed a speaker unit into the thumb and a microphone into the little finger that can be connected to any mobile handset using Bluetooth.
Artist Sean Miles designed the new gloves that double as a phone in part of his project that shows the possibilities of gadget(小配件) recycling. He uses outdated gloves and combines them with parts from mobile handsets recycled through O2, which commissioned（承担）the project. Mobile phone users will be able to keep their hands warm while they chat without taking their phones out of their pockets or handbags.
Mr Miles designed two pairs of the new gloves—one in pink and the other in brown and yellow. They will appear in an exhibition this July and visitors will be able to win the gloves. If demand is high, they will then be produced on a larger scale. O2 Recycle, which backed the project, estimates that there are already 70 million unused mobile handsets in the UK. The service pays up to £260 to those who recycle gadgets including phones, handheld consoles, MP3 players and digital cameras.
Designer Sean Miles hopes his work will get people thinking about recycling. The 41-year-old said, “I hope that my ‘Talk to the Hand’ project will get people to think again about the waste created by not recycling gadgets. If a few more people recycle their gadgets rather than send them to trash, I think this project will have fulfilled its aim.”
Bill Eyres, head of O2 Recycle, urges people to recycle their phone responsibly. He said, “There’s a pressing need for all of us to look at outdated handsets, and all the gadgets that we move on from or upgrade each year. Whether they are consoles or cameras, we should think of them as a resource that we need to recycle responsibly rather than throw them away.”
【小题1】The underlined word “O2” in Paragraph 2 is probably the name of ______.
| A．an artist | B．a company | C．a mobile | D．an exhibition |
| A．in the exhibition | B．from Mr Miles |
| C．when they are mass produced | D．after they recycle the gadgets |
| A．promote the technology of IT |
| B．enable people to talk to their hands |
| C．raise people’s awareness of recycling |
| D．attract visitors’ attention in the exhibition |
| A．New mobiles that are fashionable. |
| B．Outdated handsets that are upgraded. |
| C．Outdated gadgets that can be used for recycling. |
| D．New gloves that can be used for making phone calls. |

It's hardly surprising that weather is a favorite topic for so many people around the world—it affects where we choose to live, what we wear, our moods, and perhaps even our national characteristics.Studies have shown that changeable weather can make it difficult to concentrate, cloudy skies slow down reaction, and hot，dry winds make many people badtempered.
If you live in a place like Britain, where the weather seems to change daily if not hourly，you could be forgiven for thinking that the weather is random.In fact the weather is controlled by systems which move around areas of the globe.In the UK the weather depends on depressions (低压气流), often called lows，and anticyclones(反气旋)，also known as highs.These systems start in the Atlantic Ocean, and make their way across the British Isles from the west to the east.Highs bring sunny weather, while lows bring rain and wind.In modern times, human activities seem to be altering weather patterns.Gases produced by heavy industry change the temperature of the earth's surface，and affect cloud formation.Some researchers say that factories in Europe and North America may have been one of the causes of the droughts in Africa in the 1980s.
The human race has always tried to guess the weather，especially in areas of the world where there are frequent changes.Traditional rhymes point to early attempts to identify weather patterns; popular poems include：
Red sky at night, shepherd's delight；red sky in the morning, shepherd's warning.
Flies will swarm before a storm.
Rain before 7，clear by 11.
While folk wisdom can provide a guide to help forecast weather, today's methods of prediction increasingly rely on technology.Satellites, balloons，ships, aircrafts and weather centers with sensitive monitoring equipment, send data to computers.The data is then processed, and the weather is predicted.However，even this system cannot predict weather for longer than about a week.
【小题1】When weather keeps changing，________.
| A．people become badtempered |
| B．people's reaction slows down |
| C．people find it hard to focus on their work |
| D．people find it easy to focus on their work |
| A．random | B．moist |
| C．depressing | D．satisfying |
| A．windy | B．rainy |
| C．fine | D．snowy |
| A．Anticyclones often bring rain and wind. |
| B．Weather forecasting has been done for a long time. |
| C．Weather could never be predicted. |
| D．Modern methods of weather prediction are developed from folk wisdom. |
| A．Changes in weather. |
| B．Weather in Britain. |
| C．African droughts. |

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.
【小题1】What’s the meaning of “complex” in the second paragraph?
| A．Something that is difficult to understand. |
| B．A group of buildings together in one place. |
| C．A group of things that are connected. |
| D．A mental state that is not normal. |
| A．By fans. | B．Via ceiling vents. |
| C．Through chimneys. | D．Via ceiling vents and through chimneys. |
| A．Skies without clouds. |
| B．Little dampness. |
| C．Daily rapid temperature changes |
| D．Seasonal rapid temperature changes. |
| A．It changes in a certain range with some exception. |
| B．It changes from one extreme to another. |
| C．It remains the same without any exception. |
| D．It is hard to endure. |
| A．The engineering firm of Ove Arup&Partners. |
| B．How air-conditioning works. |
| C．Fans make Eastgate Building’s temperature comfortable. |
| D．How Eastgate Building’s temperature control system works. |
