Researchers at the University of Bedforshire have developed a new technique for powering electronic device（裝置）. The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio（無(wú)線電） waves as power.
Believed to be a world first, the team claims it could eventually eliminate (or get rid of )the need for conventional batteries. The university has now filed a patent application to secure the only rights to the technique.
Professor Allen and his team have created a system to use medium wave frequencies to replace batteries in small everyday devices like clocks and remote controls.
The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”. Professor Allen said that as radio waves have energy―like light waves, sound waves or wind waves―then, in theory, these waves could be used to create power.
“The emerging（新興的）area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said. “It’s really exciting way of taking power from sources other than what we would normally think of.”
The team is now waiting for the results of the patent application to secure recognition of the technique. Professor Allen said that the team’s achievements had all been done in their “spare time”. “Our next stage is to try and raise some real funds so that we can take this work forward and make a working prototype（模型）and maybe partner up with the right people and take this to a full product in due course,” he said.
“Power harvesting has a really important part in our future, because, just in this country, we dispose of somewhere between 20,000 and 30,000 tonnes of batteries in landfill（垃圾填理）sites every single year－that is toxic chemicals going into the ground.”
He added that development of the product could also be “commercially beneficial”. “The market for this is several billion pounds. We’ve seen market predictions for 2020 which have these kinds of figures, so there’s a lot of commercial potential in this area,” he said.
Pro-Vice Chancellor at the University of Bedfordshire, Professor Carsten Maple, said, “This type of work is a reflection of the university’s growing reputation and experience in conducting innovative（創(chuàng)新的）research.”

There are some places in the world where great cities once stood. There were trees, gardens and grass. But now these cities have gone and the places are like deserts. Scientists began to study this land to find out what happened. Many of them believed the land died when the trees were cut down.
Trees help other plants grow and help hold the soil in place. They keep the soil from blowing away. The leaves of trees on the ground keep rainwater from running off. Trees near farms protect growing plants from strong winds.
Once there were hundreds of farms in the southwestern United States. Then the farms turned into fields of dry dust. Trees might have saved these farms. But few trees grow in the dry southwest now.
Now we try to save trees. In many places, when a tree is cut down , a new tree is planted in its place . We do not want the land to die.

What would life be like without rich, creamy, mouthwatering, melt-in-your-mouth chocolate?
Life would be bitter for most Americans. They spend about $13 billion a year buying all sorts of chocolate treats.
However, for the African children who toil under slavelike conditions on cacao plantations, life is not sweet. The cacao bean is the main ingredient in the chocolate. According to a 2002 survey by the International Institute of Tropical Agriculture and the US Agency for International Development, about 284,000 children work in dangerous conditions on cacao farms in western Africa.
More than half those children are younger than 14. Many were sold into forced labor to work 12 hours or more a day on the cacao plantations.
A number of international organizations, including several African governments, recently began a program to eliminate(消除) child labor on cacao plantations. Under the program, government officials will remove children from abusive working situations while teaching farmers about child labor issues.
The program will also make borrowing money easier for cacao farmers. Officials hope farmers will use the money to invest in their farms and hire paid laborers.
小題1:The cacao bean is the main ingredient in _______.
A．treats
B．coffee
C．chocolate
D．cigarettes
小題2:How many children under 14 work on cacao farms in western Africa?
A．About 284,000.
B．About 142,000.
C．About 467,000.
D．About 876,000.
小題3:From the passage, you can reasonably conclude that _______.
A．cacao farms in western Africa rely heavily on child labor
B．children in Africa know how to make the best chocolate

Are your children liked by their teachers? All parents want their children to impress(給...的印象) their teachers and succeed in school. You can get your children to impress their teachers by following these easy steps.
Make sure they’re prepared. Teachers are impressed by children coming to school prepared to learn. Make sure they have everything they need—pencils textbooks, erasers and so on.
Require them to be active in class. Teach them to ask teachers questions when they don’t understand something. Some children think teachers are bothered by questions, but most teachers are impressed when children take the initiative(采取主動(dòng)) in asking questions. They should take part in class discussions, giving their opinions politely.
Keep your children healthy. If your children are tired and hungry, they won’t be ready to learn. Children need at least 8 to 10 hours of sleep per night. Feed your children a solid breakfast and prepare a healthy lunch. Provide them with fruit and other healthy foods—apples or bananas are better for them than cookies.
Make sure that your children do their homework. If they really don’t understand it, discuss it with them patiently. Don’t help them do their homework. Teachers can always tell who it is that does the work.
Teach your children good manners and habits. Children need to arrive at the school punctually, and be polite to their teachers and classmates. Parents need to teach these skills at home.

When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are interested in what they leave behind: their poop(排泄物). At a recent meeting in Denver, Professor Brown at the university presented her research showing how panda poop could inspire a new way to obtain energy from plants, which are a renewable energy source. Usually, plants can be called biomass(有機(jī)燃料) when they are used as an energy source.
Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists something about breaking down biomass. Pandas—or at least the bacteria in their stomachs—are very good at getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda has only one stomach. Bamboo comes in, and poop goes out.
Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two pandas, YaYa and LeLe living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break down biomass, including one that had never been found in pandas. Brown says that because the poop contains bacteria that break down biomass, it could also be used to break down other types of biomass.
Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn biomass—like grass or other plants—into fuel.
Brown says she doesn’t mind handling panda poop. “It’s probably the most pleasant material to work with,” she says, “My colleagues and I have been working with other poop for a long time, and we can assure you it has a fairly pleasant smell associated with it.”
小題1:The importance of studying panda poop is _______.
A．to create a renewable energy from plants
B．to explore a new way to get energy from plants
C．to learn a lesson of energy from panda poop
D．to figure out how the bacteria work for us mankind
小題2:The process of the panda poop project can be described as ______.
a. Identify the chemicals helpful to break down biomass.
b. Find the bacteria in panda poop which break down bamboo.
c. Reproduce the chemicals in the lab to turn biomass into energy.
d. Analyze how the bacteria in panda poop work in panda’s stomach.
A. a, b, d, c          B. a, d, c, b          C. b, a, d, c          D. b, d, a, c
小題3:What does the author mainly want to express in the 2nd paragraph?
A．Pandas don’t digest bamboo the same way as cows.
B．Pandas are capable of getting energy using stomachs.
C．Pandas can get energy from bamboo more efficiently.
D．Scientists have learnt something new from panda poop.
小題4:What does Professor Brown think of working with panda poop?

Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and then, after a full day of work, going back home to Beijing and having dinner there.
Sounds unusual, doesn't it? But it's not that unrealistic, with the development of China’s high—speed railway system. And that’s not all. China has an even greater high-speed railway plan—to connect the country with Southeast Asia, and eventually Eastern Europe.
China is negotiating to extend its own high·-speed railway network to up to 17 countries in 10 to 15 years, eventually reaching London and Singapore.
China has proposed three such projects. The first would possibly connect Kunming with  Singapore via Vietnam and Malaysia. Another could start in Urumqi and go through Kazakhstan and Uzbekistan, and possibly to Germany. The third would start in the northeast and go north through Russia and then into Western Europe.
If China’s plan for the high-speed railway goes forward, people could zip over from London to Berlin in under two days.
The new system would still follow China’s high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes.
China’s bullet train(高速客車(chē)),the one connecting Wuhan to Guangzhou, already has the   World’s fastest average speed. It covers 1,069 kilometers in about three hours.
Of course, there are some technical challenges to overcome. There are so many issues that need to be settled, such as safety, rail gauge(軌距),maintenance of railway tracks. So, it’s important to pay attention to every detail.
But the key issue is really money. China is already spending hundreds of billions of yuan on domestic railway expansion.
China prefers that the other countries pay in natural resources rather than with capital  investment. Resources from those countries could stream into China to sustain development.
It’ll be a win-win project. For other countries, the railway network will definitely create more opportunities for business, tourism and so on, not to mention the better communication among those countries.
For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China’s far west. We foresee that in the coming decades, millions of people will migrate to the western regions, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west once and for all. And they’11 trade with Central Asian and Eastern European countries.
小題1:China’s new high-speed railway plan will be a win-win project because     .
A．China will get much-needed resources and develop its western regions
B．China and the countries involved will benefit from the project in various ways
C．China will develop its railway system and communication with other countries
D．the foreign countries involved will develop their railway transportation, business and tourism
小題2:According to the passage, the greatest challenge to the new high-speed railway plan is     .
A．technical issues
B．safety of the system
C．financial problems
D．maintenance of railway tracks
小題3:Which of the following words best describes the author’s attitude towards China’s high-speed railway plan?
A．Critical.B．Reserved.C．DoubtfulD．Positive.
小題4:Which of the following might be the best title for the passage?
A．New Railway Standards
B．Big Railway Dreams
C．High-speed Bullet Trains
D．International Railway Network

Recently Dr. Cleiman has proved that everyone has a daily energy cycle. During the hours when you labor (work) through your work, you may say that you are “hot”. That is true, the time of day when you feel most energetic is when your cycle of body temperature is at its peak (頂峰). For some people the peak comes during the forenoon (上午前). For others it comes in the afternoon or evening. No one has discovered why this is so.
Much family quarrelling ends when husbands and wives realize what this energy cycle means and which cycle each member of the family has.
You cannot change your cycle, but you can learn to make your life fit it better. “Habits can help,” Dr. Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day, rise before your usual hour, and then you will work better at your low point.
Get off to a slow start which saves your energy. Get up with a lazy yawn(哈欠) and stretch(伸展). Sit on the edge of bed before putting your feet on the floor. Avoid the troublesome searching for clean clothes by laying them out the night before.
小題1:Dr. Cleiman did not explain in the passage ___________.
A．how people can make their life fit their cycle
B．whether everyone has a daily cycle or not
C．why people have their energy cycle at different times
D．what will happen in the family if the couple fail to realize which cycle each member has
小題2:For what reason may husbands and wives quarrel with each other?
A．Either of them gets up late in the morning.
B．Husbands and wives have different cycles of energy.
C．Either of them wants to change the cycle of the other’s.
D．They do not know which cycle they themselves have.
小題3:According to the passage, ____________.
A．one works better at one’s peak energy point
B．if you know your cycle you can change it to fit your life.
C．whenever you feel hot, your energy cycle reaches the highest
D．your energy cycle must be in the morning if you can get up early
小題4:Which of the following can save your energy in the morning?
A．Getting up late.
B．Jumping out of bed as quickly as possible.
C．Looking for clean clothes.
D．Sitting for a while before getting out of bed.

Birds that are half-asleep — with one brain hemisphere (半球) alert(警覺(jué)) and the other sleeping — control which side of the brain remains awake, according to a new study of sleeping ducks.
Earlier studies have recorded half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.
Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze(注視) direction.
Also, birds napping (打盹) at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in inner spots, outer birds half-asleep during some 32 percent of napping time.
“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain,” the researchers say.
The results provide the best evidence for a long-standing assumption that single-hemisphere sleep developed over time as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He’s seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open.
Useful as half-sleeping might be, it’s only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.
Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds’ half-brain sleep “is just the tip of the iceberg.” He supposes that more examples may turn up when we take a closer look at other species.
小題1:According to the passage, birds often half sleep because ______.
A．they have to watch out for possible attacks
B．their brain hemispheres take turns to rest
C．the two halves of their brain are differently organized
D．they have to constantly keep an eye on their companions
小題2:What is implied about the example of a bird’s sleeping in front of a mirror?
A．An imagined companion gives the bird a sense of security.
B．Birds prefer to sleep in pairs for the sake of their security.
C．The phenomenon of birds napping in pairs is widespread.
D．A single pet bird enjoys seeing its own reflection in the mirror.
小題3:It can be inferred that _______.
A．Birds never sleep with both hemispheres resting at once.
B．Inner ducks depend on single-hemisphere sleep, rather than total relaxation, as often as birds napping at the end of the line do
C．It is not the first time for scientists to research on birds’ half-brain sleep
D．Birds hardly sleep without a companion
小題4:By saying “just the tip of the iceberg”, Siegel suggests that _______.
A．half-brain sleep has something to do with icy weather
B．the mystery of half-brain sleep is close to being solved
C．most birds living in cold regions tend to be half sleepers
D．half-brain sleep may exist among other species

The flying fox is not a fox at all. It is an extra large bat that has got a fox’s head, and that feeds on fruit. Like all bats, flying foxes hang themselves by their toes (趾) when at rest, and travel in great crowds when out flying. A group will live in one place for years. Sometimes several hundreds of them occupy a single tree. As they return to the tree towards sunrise, they quarrel among themselves and fight for the best places until long after daylight.
Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her chest wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls to the ground. Then the older ones fly down and try to pick it up. If they fail to do so, it will die. Often hundreds of baby bats can be found lying on the ground at the foot of the tree.
小題1:The passage tells us that there is no difference between the flying fox and the ordinary bat in ______.
A．their size B．their appearance
C．the kind of food they eat D．the way they rest
小題2:Flying foxes ______.
A．double their number every year
B．fight and kill a lot of themselves
C．move from place to place very often
D．lose a lot of their young
小題3:At daybreak every day flying foxes begin to ______.
A．fly out toward the sun
B．look for a new resting place
C．come back to their home
D．go out and look for food
小題4:Flying foxes have fights ______.
A．to occupy the best resting places
B．only when it is dark
C．to protect their homes from outsiders
D．when there is not enough food
小題5:How do flying foxes care for their young?
A．They only care for their own babies.
B．They share the feeding of their young.
C．They help when a baby bat is in danger.
