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（新兴的）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（创新的）research.”

举一反三
Teaching to the test is a curious phenomenon. Instead of deciding what skills students ought to learn, helping students learn them, and then using some reasonable methods of assessment to discover whether students have mastered the skills, teachers are encouraged to reverse the process. First, one looks at a commercially available test. Then, one distills (提取) the skills needed not to master reading, say, or math, but to do well on the test. Finally, the test skills are taught.
The ability to read or write or calculate might infer the ability to do reasonably well on standardized tests. However, neither reading nor writing develops simply through being taught to take tests. We must be careful to avoid mistaking preparation for a test of a skill with the acquisition of that skill. Too many discussions of the basics of skills make this fundamental confusion because people are test-centered rather than concerned with the nature and quality of what is taught.
Recently, many schools have faced what could be called the crisis of comprehension or, in simple terms, the phenomenon of students with phonic and grammar skills still being unable to understand what they read. These students are capable of taking tests and filling in workbooks. However, they have little or no experience reading or thinking, and talking about what they read. They know the details but can"t see or understand the whole. They are taught to be so concerned with grade that they have" no time or ease of mind to think about meaning, and reread things if necessary.
小题1:As is indicated in the second paragraph, the author finds it strange that __.
| A．tests are used to assess students" skills |
| B．skills are determined before tests are set |
| C．teaching is aimed to prepare students for tests |
| D．teachers use some reasonable methods of assessment |
| A．students" poor phonic and grammar skills |
| B．teaching that takes up much of students" free time |
| C．teaching that emphasizes details rather than the whole |
| D．students" lack of ability to think about what they read |
| A．the basics of skills have been discussed too much |
| B．the nature and quality of what is taught are fully concerned |
| C．skills in general are not only useless but often mislead students |
| D．doing well in a test does not necessarily mean acquiring the skill |
The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin(弹性树脂) that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris (石头碎片) or even on-purpose destruction. The automaker admits its results vary depending on the temperature and the depth of the damage, but adds this is the only paint like it in the world, and tests prove it works. Minor scratches, the most common type, are said to slowly fade over about a week. And once they"re gone, there is no trace that they were ever there. The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period.
Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents. But the complete auto-healing won"t come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 U.S. to the price of a car. It plans to use its new chemical mixture only on its X - Trail SUVs in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven"t been made yet, if it"s a hit there, you can be almost sure market forces will drive it to these shores, as well.
小题1:From the article, we can find that_______.
| A．the paint has already been used on cars by now |
| B．it beats other products of its kind in its lengthy effect |
| C．car damage is mainly caused by scratches and scrapes |
| D．marketing this paint in Europe is not under way |
| A．last 3 years before it is re-applied again |
| B．fade only in a few days |
| C．help to protect cars from minor paint damage |
| D．reduce car scrape incidents to 20 percent |
| A．The paint was developed by Nissan Motor Company. |
| B．The paint might work better in summer than in winter. |
| C．The mark on the car could disappear as soon as the paint is applied. |
| D．The paint is very popular in Japan. |
The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.
小题1:The first paragraph tells us that _____.
| A．all living things in nature depend on each other |
| B．everything in nature can’t exist without the help of man |
| C．man has known the importance of the balance of nature for a long time |
| D．no living thing can live naturally |
| A．all forms of life belong to a system in which all the parts can be changed for one another |
| B．it is only during the last few years that man has generally known the balance of nature |
| C．there are some living things which can exist by themselves without change |
| D．we can’t change one form of life without destroying the balance of nature |
| A．man is always anxious to control his activities within limits |
| B．man is always too eager in planning for distant future |
| C．man often fails to think about their future results of his action |
| D．man often feels that he will have to give up in despair |
| A．Cutting down woods does little harm to human beings. |
| B．Man has to pay much more attention to the future results of his present action. |
| C．Oxygen comes from forests. |
| D．The passage tells us to try our best to get as much as possible immediately. |
The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall are almost too short to be noticed. Summer is the best time, as food is usually plentiful. But it is also the time when Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store, for seldom can enough animals be killed in winter to feed a family.
The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21st and August 21st the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sunshine at all. Around Oct. 21st the Eskimos of Northern Greenland see the sun set directly south of them, and they don’t see it again until February 22nd. All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker.
Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and moon provide a little light. The northern lights also help the Eskimo to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo’s eyes.
小题1:Which of the following statements is NOT true?
| A．Eskimos do not usually eat wolves. |
| B．Eskimos like to chase one another. |
| C．Eskimos depend heavily on water. |
| D．Eskimos are meat-eaters. |
| A．Dark with a little light. |
| B．A little dark. |
| C．Not dark at all. |
| D．Extremely dark. |
| A．Eskimos are more likely to eat wolves in summer |
| B．Eskimo women are responsible for housework |
| C．meat is the main source of food for the Eskimo |
| D．hunting is an important part of Eskimo life |
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.”
小题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 |
| 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. |
小题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. |
| A．Sick | B．Challenging | C．Inspiring | D．Enjoyable |
