In the late 1970’s,many people in North America turned their attention to environmental problems ,and new steel — and — glass skyscrapers were widely criticized. Some ecologists (生態(tài)學(xué)家)pointed out that a number of tall buildings in a city often overburden public transportation.
Skyscrapers are also lavish consumers of electric power and water. In just one recent year, the addition of 17 million square feet of skyscraper office space in New York City itself has already raised the top daily demand for electricity by 120, 000 kw — enough to supply the entire city of Albany in New York area for a single day.
Glass—walled skyscrapers can also be especially wasteful. The heat loss ,or gain, through a wall of half 一 inch plate glass is more than ten times that through a typical ordinary wall filled with bricks or board. In order to decrease the pressure on heating and air — conditioning equipment, builders of skyscrapers have begun to use double—layered glass ,and reflective glasses coated with silver or gold mirror films that could reduce glare (強(qiáng)光)as well as heat gain. However, mirror — walled skyscrapers may raise the temperature of the surrounding air and affect neighboring buildings as well.
Skyscrapers put a severe pressure on a city's sanitation (衛(wèi)生)facilities, too. If fully occupied, the towers just within the central area of New York would alone produce 2. 25 million gallons of waste water each year^—as much as the city size of Stanford, Connecticut, which has a population of more than 109,000.
【小題1】The underlined phrase“ lavish consumers ”in the 2nd paragraph probably means ____
A.trash producers | B.great spenders | C.pressure makers | D.poor customers |
A.show how skyscrapers manage to lessen their pressure |
B.explain why skyscrapers can control its air conditions |
C.describe further how wasteful skyscrapers could be |
D.present the stability of skyscrapers in modern buildings |

B.the central area of New York is as large as the city of Stanford |
C.more than 109,000 people live in the skyscrapers in New York |
D.New York produces 2. 25 million gallons of waste water each year |
A.positive | B.doubtful | C.grateful | D.negative |

In general, people talk about two groups of colours warm colours and cool colours. Researchers in psychology think that there are also two groups of people people who prefer warm colours and people who prefer cool colours.
The warm colours are red, orange and yellow. Where there are warm colours and a lot of light, people usually want to be active. People think that red, for example, is exciting. Sociable people, those who like to be with others, like red. The cool colours are green, blue and violet. These colours, unlike warm colours , are relaxing. Where there are cool colours, people are usually quiet. People who like to spend time alone often prefer blue.
Red may be exciting, but one researcher says that time seems to pass more slowly in a room with warm colours than in a room with cool colours. He suggests that a warm colour, such as red or orange is a good colour for a living room or restaurant. People who are relaxing or eating do not want time to pass quickly. Cool colours are better for offices or factories if the people who are working there want time to pass quickly.
Researchers do not know why people think some colours are warm and other colours are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue and violet are cool. Perhaps warm colours remind people of warm days and the cool colours remind them of cool days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.
【小題1】Which of the following colours belong to cool colours?
A.Yellow, green. | B.Blue, violet. |
C.Black, blue. | D.Brown, white. |
A.Sociable people like warm colours. |
B.Warm colours can make people excited. |
C.People who like to be with others don’t like red. |
D.Where there are warm colours, people want to be active. |
A.Red or orange for offices. |
B.Orange for dining-rooms. |
C.Blue for bedrooms. |
D.Red for studies. |
A.It shows the reason why people think some colours are warm and others are cool. |
B.Warm colours remind people of warm days. |
C.Cool colours remind people of cool days. |
D.People have an agreeable opinion of warm colours and cool colours. |

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (頭皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.
【小題1】BCI is a technology that can ________.
A.help to update computer systems |
B.link the human brain with computers |
C.help the disabled to recover |
D.control a person's thoughts |
A.By controlling his muscles. |
B.By talking to the machine. |
C.By moving his hand. |
D.By using his mind. |
A.scalp→computer→cap→wheelchair |
B.computer→cap→scalp→wheelchair |
C.scalp→cap→computer→wheelchair |
D.cap→computer→scalp→wheelchair |
A.Switzerland, the BCI Research Center |
B.New Findings About How the Human Brain Works |
C.BCI Could Mean More Freedom for the Disabled |
D.Robotic Vehicles Could Help to Cure Brain Injuries |

The ozone layer(臭氧層) is a thin layer of gas around the earth. It forms a special “blanket” around the planet. This “blanket” protects the earth from dangerous rays produced by the sun. Without the ozone layer, the earth’s climate could warm to dangerous levels. This increase in temperature would threaten our survival. Scientists recently have discovered a hole in the ozone layer above the Antarctica. Now there is great concern that this warning has started, endangering all life on the earth.
What has destroyed part of the ozone layer? Scientists do not know for sure. They suspect that our popular spray cans (噴漆罐) have played a part in the damage. Many spray cans contain dangerous gases. These gases might have destroyed the ozone layer fifteen miles above the earth’s surface, The chemicals used in refrigerators (冰箱) and air conditioners may contribute to the problem, too.
Many scientists believe that the destruction of the ozone layer is a serious problem for people everywhere. Global warming could change weather patterns around the world. Farmers and ranchers(牧場(chǎng)主) could find it more and more difficult to produce enough food for the earth’s people. If more of the sun’s dangerous rays reached the earth, there also could be an increase in skin cancers. Some skin cancers might cause people to die. Although some scientists do not believe there is a serious danger, obviously no one wants to take any chance on such a possibility.
Can scientists repair the hole in the ozone layer? They really don’t know the answer to that question. Can people do anything to save the ozone layer that the earth still has? Scientists stress the need to limit the use of spray cans and other items that contain the dangerous gases. This will not be an easy task. People all over the world use these items. Solving the problem certainly will require commitment and cooperation from everyone.
【小題1】The ozone layer exists to _____.
A.warm the earth to a proper level for life |
B.protect the earth from dangerous sun rays |
C.make all life on the earth in a dangerous situation |
D.prevent human beings from being harmed from the earth |
A.Scientists aren’t sure what has destroyed part of the ozone layer. |
B.Scientists recently have discovered a hole in the Antarctica. |
C.Scientists prove that spray cans have destroyed part of the ozone layer. |
D.Global warming doesn’t affect weather patterns around the world. |
A.spray cans | B.refrigerators | C.ranchers | D.a(chǎn)ir conditioners |
A.scientists are badly in need of others’ help |
B.items containing dangerous gases should be forbidden |
C.scientists can’t afford so much money to take measures |
D.people all over the world use items containing dangerous gases |

All around the world, shoppers flock to Wal-Mart to buy everything. In Texas, they come for another reason: to see the wind turbine(渦輪機(jī)), which supplies 5% of the store’s electricity. It along with other facilities, such as exterior walls coated with heat-reflective paint, makes this Wal-Mart a green giant.
The laws of economics suggest that Wal-Mart, with 5, 200 stores worldwide, influences everything including the price of all kinds of goods. It throws its weight behind environmental responsibility, and the impact could be amazing. “One little change in product packaging could save 1, 500 trees,” says Wal-Mart CEO Lee Scott.“If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day you have made a huge difference.”
Scott wants Wal-Mart to do its part too. He has promised to cut the existing greenhouse-gas emissions(排放)over the next few years and promised to construct new stores that are more efficient. He wants Wal-Mart’s fleet of more than 7, 000 trucks to get twice as many miles per gallon by 2015. Factories that show Wal-Mart they’re cutting air pollution will get preferential treatment in the supply chain. Wal-Mart says it’s working with consumer-product manufacturers to reduce their packaging and will reward them if they do so.
Some people may doubt it is a bid to attract attention from Wal-Mart’s controversial labor and health-insurance practices. But it’s not just window dressing, because Wal-Mart sees profits in going green. Scott says, “This is a business philosophy, not a social philosophy. We don’t go where we don’t think there’s a great interest in change.”
Like Bill Gates, who started his charitable foundation, Scott happens to be promoting Wal-Mart’s image at a time when his company’s reputation is declining. He acknowledges that he launched the plan partly to shield (保護(hù))Wal-Mart from bad press about its contribution to global warming. “By doing what we’re doing today, we avoid the headline risks that are going to come for people who did not do anything,” he says. “At some point businesses will be held responsible for the action they take.” Meanwhile, should Wal-Mart succeed at shrinking its environmental footprint and lowering prices for green products, both the planet and the company will profit.
【小題1】 We can infer from the passage that ______.
A.Lee Scott is Wal-Mart’s CEO |
B.there are 5, 200 stores in the world |
C.Wal-Mart has a great influence on the world market |

A.Wal-Mart predicts huge profits in its green activity. |
B.Wal-Mart’s green activity is just window dressing. |
C.Wal-Mart aims to solve its health-insurance practices. |
D.Wal-Mart doesn’t have any social responsibility at all. |
A.Reduce air pollution in its present stores. |
B.Give favorable treatment to its consumers. |
C.Ask the factories to reduce their packaging. |
D.Demand the fleet of trucks to use more fuel than before. |
A.Provide the background of the green plan. |
B.Stress the purpose of Wal-Mart’s green plan. |
C.Present the risk that Wal-Mart is facing nowadays. |
D.Analyze the similarity between Bill Gates and Scott. |

Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels (松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
【小題1】The study done by Rob Swihart and Jake Goheen is to ________.
A.find out the living conditions for squirrels |
B.learn squirrels’ influence on black walnut trees |
C.do something to get rid of squirrels |
D.save the forests in the American state of Indiana |
A.the way they gather the walnut |
B.the time they have winter sleep |
C.the place they have winter sleep |
D.the place they store the walnuts |
A.red squirrels eat more nuts than gray squirrels |
B.gray squirrels and red squirrels will have severe fights |
C.nuts above the ground will not develop into plants |
D.seeds can be traps for other animals in the forest |
A.The black walnut is equally attractive to both gray and red squirrels. |
B.Gray squirrels do more harm to the forest than red squirrels. |
C.Red squirrels and gray squirrels have helped the spread of walnut trees. |
D.The cleaning of forest land benefits red squirrels directly. |

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men”, said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.
“The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
【小題1】The underlined word “l(fā)ongevity” in the second paragraph probably refers to ________.
A.health | B.long life | C.a(chǎn)geing | D.effect |
A.men’s heart cells | B.women’s ageing process |
C.the gender difference | D.hearts and long life |
A.women have more cells than men when they are born |
B.women can replace the cells that enable the heart to beat |
C.the female heart loses few of the cells with age |
D.women never lose their pumping power with age |
A.enable your heart to beat much faster | B.find out the reason for ageing |
C.exercise regularly to keep your heart healthy | D.prevent your cells from being lost |
A.the reason why ageing takes a greater loss on the male heart has been found out |
B.scientists are on the way to finding out why the male heart loses more of the cells |
C.the team has done something to prevent the male from suffering the greater loss |
D.women over 70 could lose more heart cells than those at the age of 20 |

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. Jet lag interferes with a person's normal times for sleeping and waking. People with jet lag may feel extremely tired for several days. They also may have problems thinking clearly and remembering.
Kwangwook Cho is a researcher at the University of Bristol in Britain. He reported the findings of his jet lag study in the publication Nature Neuroscience.
The study involved twenty young women who worked for international airlines. The women had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.
Mister Cho took some fluid from the women's mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains using magnetic resonance imaging. This is a way to measure the size of the brain's temporal lobes.
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
Mister Cho says he believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently affect memory.
【小題1】According to the text, jet lag _____.
A.can cause difficulties in speaking |
B.can make people feel tired for a few weeks |
C.is the illness only found in people who work on the airplanes |
D.can be caused by flying over several time zones in an airplane |
A.the conclusion was questioned by many scientists |
B.scientists fear that his research is not done properly |
C.every scientific conclusion needs the support from many tests |
D.the woman who were studied in the research were not healthy |
A.The cause of jet lag. |
B.A story of a group of flight attendance. |
C.A research about the effects of jet lag on the brain. |
D.The importance of having enough rest after long flights. |

The economic growth that many nations in Asia and increasingly Africa have experienced over the past couple of decades has transformed hundreds of millions of lives – almost entirely for the better. But there’s a byproduct to that growth, one that’s evident – or sometimes less than evident – in the smoggy, smelly skies above cities like Beijing, New Delhi and Jakarta. Thanks to new cars and power plants, air pollution is bad and getting worse in much of the world, and it’s taking a major toll (傷亡人數(shù),代價(jià)) on global health.
How big? According to a new analysis published in the Lancet, more than 3.2 million people suffered deaths from air pollution in 2010, the largest number on record. That’s up from 800,000 in 2000. And it’s a regional problem: 65% of those deaths occurred in Asia, where the air is choked by diesel soot (內(nèi)燃發(fā)動(dòng)機(jī)煙霧) from cars and trucks, as well as the song from power plants and the dust from endless urban construction. In East Asia and China, 1.2 million people died, as well as another 712,000 in South Asia, including India. For the first time ever, air pollution is on the world’s top – 10 list of killers, and it’s moving up the ranks faster than any other factor.
So how can air pollution be so damaging? It is the very finest soot – so small that it roots deep within the lungs and then enters the bloodstream – that contributes to most of the public – health toll of air pollution including death. Diesel soot, which can also cause cancer, is a major problem because it is concentrated in cities along transportation zones affecting overpopulated areas. It is thought to contribute to half the deaths from air pollution in urban centers. Fro example, 1 in 6 people in the U.S. live near a diesel – pollution hot spot like a rail yard, port terminal or freeway.
We also know that air pollution may be linked to other non – deadly diseases. Fortunately in the U.S. and other developed nations, urban air is for the most part cleaner than it was 30 or 40 years ago, thanks to regulations and new technologies like the catalytic converters (催化式排氣凈化器) that reduce automobile emissions. Govemments are also pushing to make air cleaner – see the White House’s move last week to further tighten soot standards. It’s not perfect, but we’ve had much more success dealing with air pollution than climate change.
Will developing nations like India eventually catch up? Hopefully – though the problem may get worse before it gets better. The good news is that it doesn’t take a major technological advance to improve urban air. Switching from diesel fuel to unleaded (無鉛燃油) helps, as do newer and cleaner cars which are less likely to send out pollutants. Power plants – even ones that burn mineral fuels like coal – can be fitted with pollution – control equipment that, at a price, will greatly reduce smog and other pollutants.
But the best solutions may involve urban design. In the Guardian, John Vidal notes that Delhi now has 200 cars per 1,000 people, far more than much richer Asian cities like Hong Kong and Singapore. Developing cities will almost certainly see an increase in car ownership as residents become wealthier – and that doesn’t have to mean deadly air pollution. Higher incomes should also lead to tougher environmental regulations, which is exactly what happened in the West. We can only hope it happens before the death toll from bad air gets even higher.
【小題1】What tends to give rise to the highest death toll according to the passage?
A.The lack of tight environmental protection standards. |
B.The increasing numbers of the diesel cars and trucks. |
C.The frighteningly high death rate from deadly cancer. |
D.The world’s serious air pollution such as soot and dust. |
A.consequence | B.solution | C.reform | D.design |
A.the diesel soot is too small to be seen |
B.the diesel soot is much too poisonous to breathe |
C.the diesel soot roots in lungs and gets into blood |
D.the diesel soot can also contribute to deadly cancer |
A.the global economic growth is mainly to blame for air pollution and climate change |
B.the developing countries are repeating the same mistakes as the developed ones made |
C.the ecological situation and air pollution in India are becoming worse and worse |
D.the unbeatable air is increasingly becoming a major killer throughout the world |
A.the making of tougher environmental regulations alone is of little use |
B.more sever regulations should be made to handle air pollution |
C.the urban construction in western developed countries is the best choice |
D.the pace of development has to be slowed down to reduce air pollution |
