All around the world, shoppers flock to Wal-Mart to buy everything. In Texas, they come for another reason: to see the wind turbine（涡轮机）, 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 （保护）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.

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger ,but we also affect our water supply in less obvious ways .You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater . Groundwater does not come from lakes or rivers .It come from underground . The more roads and parking lots we pave ,the less water can flow into the ground to become groundwater .
Human activity is not responsible for all water shortages(短缺). Driver climates are of course more likely to have droughts(干旱) than areas with more rainfall ,but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference ,too In the United States ,a family of four can use 1.5tons of water a day ! This shows how much we depend on water to live ,but there’s a lot we can do to lower the number .
You can take steps to save water in your home .To start with ,use the same glass for your drinking water all day .Wash it only once a day .Run your dishwasher (洗碗机)only when it is full .Help your parents fix any leaks in your home . You can even help to keep our water supply clean by recycling batteries instead of throwing them away .

Watercress is positively packed with healthy vitamins and minerals. The writings of both the Romans and the Ancient Greeks record the consumption of watercress by all classes. Hippocrates, “the father of medicine”, was so convinced that watercress was a great healer that he built his first hospital next to a stream so that he could grow a plentiful supply of the shiny green leaves for his patients. The Romans chewed watercress in large quantities, believing that it would cure baldness. They, too, looked with favor on watercress as a salad.
Watercress sandwiches were traditionally a breakfast item in nineteenth-century Europe. The most basic type of watercress sandwich has two pieces of white bread with a mixture of butter and watercress greens . A nickname(绰号)for the vegetable, in fact, was “poor man’s bread”, because watercress was often eaten on its own for breakfast by families that could not afford the bread to go with it.
Watercress is a member of the mustard(芥菜) family. It contains vitamins C(66mg per 100g), K and A, and is also a valuable source of minerals such as iron, potassium, copper and calcium. The mustard oils in its silky leaves and stems(茎)contain an ingredient known as PEITC. Recent research has proved that PEITC can prevent the growth of cancer cells and, in some cases, actually destroy them.
The best watercress has silky green leaves without any marks and has undamaged stems, The older the plant, the darker are its leaves and the thicker its stems. This means a higher concentration of oils and vitamins. Young watercress, on the other hand, may be harvested after only twenty-eight days growth and has a milder taste. It is best to eat watercress fresh and raw , to keep more of its valuable nutrients, but it can be lightly cooked and used as an alternative to spinach—another dark green vegetable—in various recipes. From soups to salads, watercress is now considered around the world as a natural and healthy super food.
【小题1】From paragraph 1, we can learn that________.
| A．watercress is usually grown in wet areas |
| B．the ancient Greeks only used watercress for medicine |
| C．watercress is the most ancient vegetable known to man |
| D．the Romans rubbed watercress on their heads to cure baldness |
| A．butter | B．watercress | C．breakfast | D．bread |
| A．has lighter green leaves |
| B．contains more minerals |
| C．is better for medical use |
| D．is more suitable for eating raw |

Hospital emergency rooms treat injured fingers all the time. Without treatment, a bad cut can lead to permanent damage. But how should a person know when a bleeding cut is serious enough to require medical attention? We asked Dr Martin Brown, chairman of the department of emergency medicine at Inova Alexandria Hospital in Virginia.
First, the medical term for a cut or tear in the skin is a laceration(严重划破，撕裂伤). Dr Brown says the length is usually not as important as the depth. He says a long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep. “If you have a short but deep laceration where there’s been a structure underneath that’s been damaged － a tendon, a nerve, a blood vessel,” says Martin, “it may, in fact, need professional attention.”
Some injuries － like a fingertip that gets cut off － might even require surgery to repair. That requires a specialist to either file(锉平) down the bone or reattach the fingertip. More often, filing down the bone is what is done because reattaching a fingertip is often not successful.
How a wound bleeds can be a sign of how serious it is. Minor cuts usually produce what is known as venous (静脉) bleeding. This means the blood flows steadily from the injury. The bleeding will often stop when pressure is put on the wound. Dr Brown says in most cases holding direct pressure with clean gauze or a cloth for four to five minutes should stop the bleeding. With a cut finger, holding the hand above the heart can reduce the loss of blood. But if a cut appears to be pumping blood out with some force, this may be a sign of arterial(动脉) bleeding. This kind of injury should be treated by a medical professional as soon as possible.
Even a cut that does not require medical attention must be kept clean to prevent infection. Small cuts should be cleaned gently with clean water. Use a washcloth to clean the area if the wound is dirty. Dr Brown says cuts should be covered with a clean, dry bandage.
【小题1】What does the writer want to tell the readers in the first paragraph?
| A．Hospital emergency rooms always treat injured fingers. |
| B．A bleeding cut is serious enough to require medical attention |
| C．Dr Martin Brown is in charge of Inova Alexandria Hospital. |
| D．It is important for us to be able to tell how serious a finger cut is. |
| A．a finger cut without treatment can lead to permanent damage |
| B．the length of a cut on a finger is more important than the depth |
| C．a long but not very deep cut often doesn’t need professional attention |
| D．a short but deep laceration that has been damaged need professional attention. |
| A．repair | B．rebuild | C．reconstruct | D．reconnect |
| A．Hospital Emergency Treatments For Injured Fingers |
| B．When a Cut Finger Is More Serious Than It Might Seem |
| C．Serious Finger Cut That Requires Medical Attention |

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.
Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”
【小题1】What can we learn about Dr. Marcy from the passage?
| A．He is fond of watching Jupiter. |
| B．He is from a scientist family. |
| C．He dislikes working with Paul Butler. |
| D．He is interested in finding life in outer space. |
| A．The planet is not as protective as Jupiter. |
| B．The planet is close to star 55Cancri. |
| C．The planet proves to be a gas planet. |
| D．The planet is as large as Jupiter. |
| A．1995 | B．1985 | C．2002 | D．1981 |
| A．he has found the system similar to the solar system. |
| B．he has discovered an Earth-like planet there. |
| C．he has discovered a rocky planet there. |
| D．he has found signs of life in the system |
| A．they felt discouraged | B．they carried on with it |
| C．they failed in their attempt | D．they made some progress |

If the eyes are the romantic’s window into the soul, then the teeth are an anthropologist’s ( 人类学家 ) door to the stomach.
In a study published last month in the journal Science, Peter Ungar of the University of Arkansas and his partner, Matt Sponheimer of the University of Colorado, US, examined the teeth of our early human ancestors to find out what they were really eating.
They already knew that different foods cause different marks on teeth. Some cause scratches, while others cause pits (坑).The carbon left on teeth by different foods is also different. Tropical grasses, for example, leave one kind of carbon, but trees leave another kind because they photosynthesized ( 光合作用 ) differently.
Traditionally, scientists had looked at the size and shape of teeth and skulls ( 头骨 ) to figure out what early humans ate. Big flat teeth were taken to be signs that they ate nuts and seeds, while hard and sharp teeth seemed good for cutting meat and leaves. But this was proven wrong.
The best example was the Paranthropus (傍人), one of our close cousins, some of which lived in eastern Africa. Scientists used to believe Paranthropus ate nuts and seeds because they had big crests(突起)on their skulls, suggesting they had large chewing muscles and big teeth. If this had been true, their teeth should have been covered with pits like the surface of the moon. They would also have had a particular type of carbon on their teeth that typically comes from tree products, such as nuts and seeds.
However, when the two scientists studied the Paranthroupus, it turned out to have none of these characteristics. The teeth had a different kind of carbon, and were covered with scratches, not pits. This suggests they probably ate grass, not nuts and fruit stones. It was the exact opposite of what people had expected to find.
Carbon “foodprints” give us a completely new and different insight into what different species ate and the different environments they lived in. If a certain species had the kind of carbon on its teeth that came from grasses, it probably lived in a tropical grassland, for example.
【小题1】The underlined sentence in Paragraph 1 probably means that _____.
| A．anthropologists can study the structure of human stomachs by studying their teeth. |
| B．anthropologists can study the diet of early humans by studying their teeth |
| C．anthropologists can learn whether humans were healthy by looking at their teeth |
| D．anthropologists can get the most useful information about humans from their teeth |
| A．Scratches on teeth are caused by eating nuts or seeds. |
| B．Pits on teeth are caused by eating grass or leaves. |
| C．Early humans with hard and sharp teeth ate meat and leaves. |
| D．Different foods leave different marks and carbon on teeth. |
| A．tell readers that they are one of our close cousins living in eastern Africa |
| B．tell readers they had different eating habits from modern humans |
| C．prove that size and shape of skulls does not show accurately what early humans ate |
| D．tell readers that living environment makes a difference to skull structure |

There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250，000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
【小题1】What problem should be settled now in London?
| A．How to protect the city’s property |
| B．Where to build its flood defences |
| C．How to use the Thames Barrier to protect the city |
| D．How to improve the function of the old flood defences |
| A．Putting up new types of buildings with a covering of bamboo |
| B．Having air-conditioners installed in elderly care homes |
| C．Forbidding the city to build“Flower Tower” |
| D．Encouraging architects to design new types of buildings |
| A．increasing population and coal-fired power stations |
| B．rising sea levels and typhoons |
| C．extremely high temperature and rising sea levels |
| D．extra demands on energy consumption and typhoons |
| A．to tell us how to protect the big cities |
| B．to give advice on how to defend natural disasters |
| C．to explain what causes flood and heat waves |
| D．to warn us of the increasing natural disasters in big cities |
| A．Big Cities Facing Big Disasters |
| B．Big Disasters in the Future |
| C．The Increase of Natural Disasters |
| D．Solutions to Natural Disasters |

What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?
We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work.
What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.
He is a good observer, accurate, patient and objective（客观的） and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum（光谱）.
He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.
Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.
Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.
These seem to be some of the ways in which a successful scientist or technologist thinks and acts.
【小题1】Many people believe that science helps society to progress through ________.
| A．knowledge | B．more than one aspect |
| C．technology | D．the use of machines |
| A．He doesn’t find confidence and pleasure in work. |
| B．He makes efforts to investigate potential connections. |
| C．He is interested in problems that are explained. |
| D．He looks for new ways of acting. |
| A．easily believe in unchecked statements |
| B．easily criticize others’ research work |
| C．always use his imagination in work |
| D．always use evidence from observation |
| A．complete | B．accurate | C．objective | D．complicated |
| A．Application of technology |
| B．Progress in modem society. |
| C．Scientists’ ways of thinking and acting |
| D．How to become a successful scientist. |
