The world's largest solar thermal plant(太陽熱能發(fā)電站)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 (渦輪) 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.

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(白蟻堆).
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(通風(fēng)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 buildings, where up to 30% of the air is recycled.
【小題1】Why was Eastgate cheaper to be built than a conventional building?
A.It was designed in a smaller size. |
B.No air conditioners were fixed in. |
C.Its heating system was less advanced. |
D.It used rather different building materials. |
A.Fresh air from outside. | B.Heat in the building. |
C.Hollow space. | D.Baseboard vent. |
A.New York has less clear skies as Harare. |
B.Its dampness affects the circulation of air. |
C.New York covers a larger area than Harare. |
D.Its temperature changes seasonally rather than daily. |
A.a(chǎn)llows a wide range of temperatures |
B.functions well for most of the year |
C.can recycle up to 30% of the air |
D.works better in hot seasons |

Scientists in Israel have discovered a new way to test for water pollution by “l(fā)istening” to what the plants growing in water have to say.
By shining a laser beam (激光束) on the tiny pieces of algae floating in the water,the researchers said they hear sound waves that tell them the type and amount of contamination (致污物) in the water.
“It is a red light,telling us that something is beginning to go wrong with the quality of water,” said Zvy Dubinsky,an aquatic biologist at Israel’s Bar Ilan University.“Algae is the first thing to be affected by a change in water quality.”“The secret,” he said,“is to measure the rate of photosynthesis (光合作用) in the algae,meaning the plant’s ability to transform light into energy.” During photosynthesis,plants also release oxygen into the air.
Dubinsky’s technique is easy to perform because of the overabundance of algae in the planet’s water.Most of the oxygen in the atmosphere comes from algae.A prototype tester that occupies about one square meter of a laboratory desktop,shoots a laser beam at water samples to stimulate photosynthesis in the algae.But not all of the laser’s heat is used.Depending on the condition of the algae and the rate of photosynthesis,some of the heat is shot back into the water,creating sound waves,Dubinsky said.With a special underwater microphone,researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water.
“Algae suffering from lead poisoning,like waste discharged from battery and paint manufacturing plants,will produce a different sound than those suffering from lack of iron or exposure to other toxins,” said researcher Yulia Pinchasov.She said that testing algae photosynthesis can determine water quality more accurately and easily than laborintensive methods now used like chemical and radioactive carbon testing.
【小題1】The underlined word “algae” in Paragraph 2 probably refers to a kind of________.
A.instrument | B.plant |
C.wood | D.pollutant |
A.Because it floats on the water. |
B.Because it can have photosynthesis. |
C.Because it is the first to be polluted. |
D.Because it can produce different sounds. |
A.a(chǎn)lgae can produce a loud sound when polluted |
B.a(chǎn)lgae can die easily from pollution |
C.photosynthesis of the algae can only be caused by sunlight |
D.photosynthesis of the algae is related to water quality |
A.Scientists Listen to Plants to Find Water Pollution |
B.A Prototype Tester Is Used to Determine Water Pollution |
C.The Importance of Photosynthesis of the Algae |
D.The Problem of Chemical and Radioactive Carbon Testing |

After record increase in over 40 countries, Universal Robots’ lightweight robotic arms are now making their US debut (首次露面) at this year’s International Manufacturing Trade Show (IMTS) in Chicago.
The UR5 robotic arm made by Universal Robots has been announced officially “The world’s most innovative (創(chuàng)新的) robot” by The International Federation of Robotics and IEEE (Institute of Electrical and Electronics Engineers) Robotics and Automation Society. The US audience will now see the award-winning robot — along with its big brother UR10 — for the first time.
The UR5 and UR10 robotic arms are aimed at small-sized companies that thought robots were too expensive and hard to operate in existing production. The robotic arms are easily moved around the production area and present a simple user interface (界面) which lets workers quickly operate them.
Esben Ostergaard, founder and CTO (Chief Technical Officer) at Universal Robots, explains how the robots were designed to be as user?friendly as possible:
“We decided to make programming easy by developing a user interface worked together with a “teaching function” allowing the user to simply took hold of the robot arm and show it how a movement should be done. The robot can work in any production process very quickly. Our experience shows this is generally done in a few hours.”
The robots weigh as little as 40 pounds, making it possible for them to be moved around the production area to do different tasks. The UR5 can handle a load of up to 5 kilos (11 pounds), the UR10, 10 kilos (22 pounds). As soon as a worker touches the robot arm and uses a force of at least 150 Newton, the robot arm will automatically stop operating.
【小題1】According to the text, the UR5 robotic arm _____.
A.was designed by IEEE |
B.is aimed at small companies |
C.has won a number of awards |
D.made its appearance in 40 countries |
A.the programme | B.the user interface |
C.the robot arm | D.the “teaching function” |

Fish species are expected to shrink in size by up to 24% because of global warming, say scientists.
The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected.
The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish's body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size.
The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth's poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future."
Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans.
When compared with actual observations of fish sizes, the model seems to underestimate what's actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted.
Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously affect the ability of fish to reproduce. "Smaller fish produce fewer and smaller eggs which could affect the reproductive potential of fish stocks," he said.
【小題1】What's the main idea of the passage?
A.Global warming makes fish smaller. |
B.Global warming makes fish decrease in numbers. |
C.Global warming affects the fish distribution. |
D.Global warming affects the ability of fish to reproduce. |

Way back in 1662,John Evelyn,a brilliant Englishman known for his detailed diaries,wrote about disastrous effects of coal-burning on the city of London .In it,he described an infernal scene of smog.a(chǎn)ir filled with “Columns and Clouds of Smoke’’given out by small industries and residences that burned coal for fuel.
I found the description in the 2003 book When Smoke Ran like Water,by epidemiologist(流行病學(xué)家)and environmental advocator(倡導(dǎo)者)Devra Davis.In it,Davis looks back at several historic pollution events and their disastrous effect on human human health-and at how these phenomena were often Ignored or even actively covered up by then people in charge at that time.
As Davis points out,John Evelyn was ahead of his time when writing about how London’s polluted air affected the well-being of its residents.It wasn’t until nearly 300 years later,after what became well-known as the Great Smog of 1952,that the government began to address the problem in a systematic way.
For four days.Between December 5th“and 9th“,due to all accident of the weather pattern,the city was buried in a heavy fog .People were still burning coal for fuel,and low-grade coal at that time, because 0f wartime condition.A temperature inversion(轉(zhuǎn)向)trapped the smoke from the city’s fires, creating a black cloud in which people could barely find their way down the most familiar streets
Some tried to protect themselves,but most people simply went about their business. But l952’s fog was far worse than any other in memory.In the same week of the previous year, 1852 people had died in London;inl952,that number was 4703 And the deaths didn’t stop when the weather changed and the fog lifted.Davis and her colleagues analyzed data from the next several months and found that about 13000 more people died between December and March than one would have predicted from historical averages Many of them died of pneumonia(肺炎).The government,she writes.Tried to blame a bad flu season.Her detailed analysis found that explanation simply did
not pan out.
Davis writes that even today in this country ,we still have not completely absorbed the lessons of similar events.Sixty years the killer fog lifted in London,people are dying preventable deaths and suffering life.changing illnesses,simply because they must breathe the air of the cities where they live

Around the world coral reefs(珊瑚礁) are facing threats(威脅) 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(破壞性的) 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(復(fù)雜性) 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.”
【小題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·高考新課標(biāo)全國卷Ⅱ,C)Given that many people’s moods (情緒)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.
