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 (車(chē)隊(duì)) 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)，庇護(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 actions 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
D．Wal-Mart has more than 7, 000 trucks all over the world

How would you like to sleep with one half your brain asleep and the other half awake? Dolphins sleep this way. Recently, scientists at Indiana State University have discovered that ducks sleep this way too. They found that ducks sleep half awake so they can rest and watch for danger at the same time.
After putting their ducks in a row and videotaping them, some researchers found ducks on the end of each row spent more time asleep with one eye open, apparently looking for predators.
“The more the ducks felt threatened, the more they slept with one eye open,” said lead author Niels C. Rattenborg, a graduate student at Indiana State University, Terre Haute. “The unique aspect is not that they do it, but that they control it. When they sleep at the edge of a group, they tend to realize greater danger, so they spend more time sleeping with one half of their brain.” Ducks with one eye open were still awake enough to detect predators, said the authors of the study, which appears today in the journal Nature.
The researchers studied four groups of four ducks held in plastic boxes, which were arranged in a row. Ducks on the end were found to sleep with one eye open 31.8 per cent of the time, compared to 12.4 percent of the time for ducks in the central position.
Also, ducks in the central position did not open one eye more than the others, while ducks on each end kept the eye facing away from the group open 86.2 per cent of the time. Brain wave readings of the ducks showed that the half of the brain receiving signals from the closed eye indicated that half of the brain was sleeping. Signals from the half of the brain receiving signals from the open eye showed a state between fully awake and asleep.
【小題1】The under lined word “predator” is most likely to mean      .

A．a(chǎn)n animal that is likely to be friends with ducks
B．a(chǎn) human being who looks after and feeds ducks
C．a(chǎn) scientist who does research work on animals
D．a(chǎn)n animal that hunts, kills and eats other animals
【小題2】Ducks at the end of each row sleep with one eye open because      .
A．they are looking for food
B．they are watching out for danger
C．they want to enjoy the scenery
D．they are unique in their sleeping habit
【小題3】Which of the following is true according to the passage?
A．Ducks with one eye open at the edge can still enjoy a certain degree of sleep.
B．Ducks with less sense of duty usually choose to stay in the center of a row.
C．Ducks on the northern end of a row would keep their eye facing the south open.
D．A video tape recorder was the only electronic device used in the experiment.

Do you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since researches have shown that the bigger the brain, the cleverer the animal, men must be more intelligent than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” and “white matter”. While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial(空間的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries—why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎兒) are about nine weeks old, which can be seen in the action of children as young as one. A boy would try to climb a barrier (障礙物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research. www. .com
If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.
【小題1】Which of the following is true according to the first paragraph?

A．Women’s brain is 10% less than men’s

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead. 
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical is stronger than the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

The United States is full of cars. There are still many families without cars, but some families have two or more. However, cars are used for more than pleasure. They are a necessary part of life.
Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies.
Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile away from the school. When the children are too young to walk too far, their mothers take turns driving them to school. One mother drives on Mondays taking her own children and the neighbors' as well. Another mother drives on Tuesdays, another on Wednesday, and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work.
More car pools should be formed in order to put fewer cars on the road and use less gas. Too many cars are being driven. Something will have to be done about the use of cars.
【小題1】The United States is filled with cars, but      .

A．not every family has a car
B．few families have two cars or even more
C．every American has a car
D．every family has a car

Below is a selection from a popular science book.
If blood is red, why are veins (靜脈) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
Which works harder depends on whether you are busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don't they grow back in grown-ups?
Baby (or "milk") teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you're done. When they're gone, they’re gone. This is because nature figures you're set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity. Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don't really shrink! It is not that they are growing backwards — their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little or, more often, become more bent and curved.
Why does spinning（旋轉(zhuǎn)） make you dizzy (眩暈的)?
Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you're moving while you're not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s "use it, or lose it”! It's not that exercise makes you healthy; it's more that a lack of exercise leaves your body weak and easily affected by disease.
【小題1】What is the color of blood in a vein near the surface of the skin?

A．Blue. B．Light yellow. C．Red. D．Dark reddish purple.
【小題2】Why do some old people look a little shrunken as they age?
A．Because their spine is in active use.
B．Because they are more easily affected by gravity.
C．Because they keep growing backwards.
D．Because their spine becomes more bent.
【小題3】Which of the following statements about our brain is true?
A．In the long run, our brain probably works harder than our heart.
B．When our brain senses the spinning, we will fell dizzy.
C．The brains of the other mammals are as complex as those of humans.
D．Our feelings and emotions come from the most developed area in our brain.
【小題4】What is the main purpose of the selection?
A．To give advice on how to stay healthy.
B．To provide information about our body.
C．To challenge new findings in medical research.
D．To report the latest discoveries in medical science.

Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis（綠洲）, from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.
When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.
Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.
Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________.
【小題1】Ken Levin asked Argutel to walk to the north in order to ________.

A．prove that people could walk out of the desert see
B．how far away Bissel was to the edge of the desert
C．tell people not to walk in circles
D．show Argutel was a great person
【小題2】According to the passage, Ken Levin ________.
A．knew Argutel before he came to the village
B．came to Bissel to do experiments on behalf of his college
C．became the first man to walk out of the desert from Bissel Village
D．taught Bissel villagers knowledge of the North Star when he first arrived
【小題3】It can be inferred from the passage that ________.
A．Ken Levin didn’t walk south because it would take more days
B．the use of a compass was necessary to walk out of the desert
C．tourism in Bissel has been greatly developed and improved
D．Argutel became the leader of Bissel after his return
【小題4】Which of the following can most probably be found at the base of Argutel’s statue?
A．A new life starts from the fixed direction.
B．Where there is a will , there is a way .
C．A long journey starts with the first step .

Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
【小題1】What function isn’t understood by most people on Facebook?

A．Surfing the Internet. 
B．Setting safety protection. 
C．Sharing personal information. 
D．Making foreign friends. 
【小題2】What can we learn about Facebook according to the text?
A．Its process of privacy-setting is too complex. 
B．It displays everything people post. 
C．It lacks privacy controls and security features. 
D．Its post is designed for technical people. 
【小題3】What advantage can we get from making friend lists?
A．We can avoid our bosses adding us as friends. 
B．We can share applications with friends. 
C．We can separate acquaintances from family. 
D．We can hide different information from different friends.

Sports shoes that work out whether their owner has done enough exercise to warrant time in front of the television have been devised in the UK.
The shoes — named Square Eyes — contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.
The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”
Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.
Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.
Existing pedometers （計(jì)步器） normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”
【小題1】According to Swan, the purpose of her design project is to ________.

A．keep a record of the steps of the wearer
B．deal with overweight among teenagers
C．enable children to resist the temptation of TV
D．prevent children from being tricked by TV programs
【小題2】Which of the following is true of Square Eyes shoes?
A．They regulate a child’s evening TV viewing time.
B．They determine a child’s daily pocket money.
C．They have raised the hot issue of overweight.
D．They contain information of the receiver.
【小題3】What is stressed by health experts in their suggestion?
A．The exact number of steps to be taken.
B．The precise number of hours spent on TV.
C．The proper amount of daily exercise and TV time.
D．The way of changing steps into TV watching time.
【小題4】Compared with other similar products, the new design ________.
A．makes it difficult for lazy teenagers to cheat
B．counts the wearer’s steps through shaking
C．records the sudden movement of the wearer
D．sends teenagers’ health data to the receiver
【小題5】Which of the following would be the best title for the text?
A．Smart Shoes Decide on Television Time
B．Smart Shoes Guarantee More Exercise
C．Smart Shoes Measure Time of Exercise
D．Smart Shoes Stop Childhood Overweight
