Researchers at the University of Bedforshire have developed a new technique for powering electronic device(装置). The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio 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---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 tones 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.”

It’s 8:30, time for John to start work. So he turns on his radio. Then he eats breakfast. As he eats, he reads his e-mail and reviews his to-do list. Then he sits on the sofa and thinks about an article he needs to write ... Wait a minute! Radio? Breakfast? Sofa? What kind of workplace is this? Well, actually it is John’s house, and he is a telecommuter — he works at home, communicating with the workplace through the Internet.
Like John, millions of people — and their employers — are finding that telecommuting is a great way to work. Telecommuters can follow their own timetables. They work in the comfort of homes, where they can also look after young children or elderly parents. They save time and money by not traveling to work. Their employers save, too, because they need less office space and furniture. Studies show that telecommuters change jobs less often. This saves employers even more money. Telecommuting helps society, too, by reducing pollution and traffic problems.
Jobs that are suited to telecommuting include writing, design work, computer programming and accounting. If a job is related to working with information, a telecommuter can probably do it.
【小题1】From the passage we can learn that John does his job .
A.by telephone | B.through the Internet |
C.in his office | D.away from home |
A.work for several employers | B.enjoy a lot of traveling |
C.get along well with other workers | D.work on your own schedule |

How did a ban on smoking in public places come into place?
In 1998 the Smoking Kills White Paper set out a national strategy (策略) to reduce smoking prevalence (流行) and passive smoking, including in public places. The measures were voluntary and poorly carried out. After a public conference in England in 2004, the Government decided to choose for lawmaking. Scotland went first, with a ban in 2006, followed by the other nations a year later.
What is the current law?
Any person who smokes in enclosed (封闭的) public places, including pubs, offices, on public transport and work vehicles, is breaking the law. It does not extend to private houses. It is also an offence for people in charge of premises (营业场所) to permit others to smoke in them.
How was it received?
It was welcomed by most organizations except for some pub owners and restaurateurs. Many workplaces in the UK had already introduced smoke-free policies consistent with the legislation (法律,法规) before it was carried out, while others have gone beyond its basic requirements.
All railway facilities, including platforms, footbridges and other areas--whether or not fitting the definition of an enclosed public space--are covered, as are all football grounds and some cricket and athletics stadiums. School grounds are not required to be smoke-free under the legislation, but the majority now are.
How has it been forced?
Compliance (服从) in public premises has been high, with inspections suggesting that 99 per cent of places were sticking to the rules. The number of people charged for smoking in cars has been very low, which was due to the problems defining and identifying "work" vehicles. They said that a total ban on smoking in vehicles would end this confusion.
Has it improved health?
Studies in early adopters of the law, including in Scotland, suggest a reduction in hospital admissions for heart disease, which has been shown to be linked to passive smoking. There is also strong evidence of improved rates of smoking end and a drop in the number of cigarettes consumed by those who continue to smoke.
【小题1】When did the first law come out to ban smoking in public places?
A.1987 | B.1998 | C.2004 | D.2006 |
A.Jack often smokes in the office when he is alone. |
B.A taxi driver is smoking with a lady in his car. |
C.Tom smokes while thinking of his future at home. |
D.Max smokes for relaxation during time-out in the stadium. |
A.A restaurant owner. | B.A company manager. |
C.A car owner. | D.A policy maker. |
A.Most heart diseases have been proved to be linked to passive smoking. |
B.A new law will soon come out with a total ban on smoking in vehicles |
C.Cigarette-making factories will disappear soon. |
D.Most of the school grounds are not smoke-free, as it is not banned in the law. |

A Swedish man was dug out alive after being snowed in his car on a forest track for two months with no food, police and local media reported on Saturday.
The 45-year-old from southern Sweden was found on Friday, February17, too weak to say more than a few words.
He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a ruined car until they dug their way to a window and saw movement inside.
The man, who was lying in the back seat in a sleeping bag, said he had been in the car since December 19.
“Just incredible that he’s alive considering that he had no food, but also since it’s been really cold for some time after Christmas.” a rescue team member told regional daily Vasterbottens- Kuriren, which broke the news.
Ebbe Nyberg, duty officer at the Umea police, said police saw no reason to doubt that the man had been stuck in the car for a very long time.
“We would not make up something like this. The rescue services were on site too and saw the same as us.” he told Vasterbottens-Kuriren.
Umea University Hospital, where the man is recovering after being rescued by police and a rescue team, said in a statement he was doing well considering the circumstances.
Doctors at the hospital said humans would normally be able to survive for about four weeks without food. Besides eating snow, the man probably survived by going into a dormant-like(休眠似的) state, physician Stefan Branth told Vasterbottens-Kuriren.
“A bit like a bear that hibernates. Humans can do that.” he said. “He probably had a body temperature of around 31 degrees which the body adjusted to. Due to the low temperature, not much energy was used up.”
“Why the man ended up under the snow in the forest remains unknown,” police said.
【小题1】“Police saw no reason to doubt that the man had been stuck in the car for a very long time.”implies that .
A.police didn’t think it true |
B.police were sure of the fact |
C.police had some doubt on the fact |
D.police had reasons to doubt the fact |
A.he was only forty-five year old |
B.he did not use any energy |

SANTA MONICA, Calif. (KABC)一A Santa Monica High School teacher who was put on
leave after using physical force to control a student who was selling marijuana(大麻)in his classroom has received surprising support on Facebook. The incident was captured on video and has caused a sudden reaction from parents, teachers, students and even graduates. They are showing their support for Black. A Facebook page supporting "Coach Black" has over 4,700 likes. And many want him back in the classroom.
Student witnesses say Mark Black, who is also the wrestling coach, tried to confiscate(没收)a bag of marijuana and was then injured by the student with a pencil. The cellphone video shows Black locking the student's legs and pinning the student to the ground. "He just wanted him to stop and he was trying to be a teacher and help, and I don't think it was his fault." said student Kylan Townsend.
School Board member Oscar De La Tone says Mr. Black is one of his teachers at Santa Monica High School. "I know him very well. I know him to be a fair person, a good person, someone who cares deeply about his students," said De La Torre. He says that the video does not tell the whole story and that the incident brings to light the issue of drug use, something the district needs to address.
But in an email to parents, Santa Monica-Malibu Unified School District Superintendent Sandra Lyon says the teacher's behavior is "absolutely alarming." She put Black on leave during an independent investigation.
Lyon has come under fire from parents for initially saying the kind of physical action used by the teacher was unacceptable. On Saturday, Lyon released the following statement to Eyewitness News: "I want to stress that teachers are at times confronted with difficult, even threatening situations, and they must make judgment calls to protect safety. I want to emphasize that putting the teacher who was involved in this incident on leave until completion of an independent investigation is a matter of standard policy and practice; it in no way prejudices the outcome of the investigation."
Students hope the situation will have a quick and just resolution. An online petition(请原书) pas also peen createu by one of Black's former students. The petition has already gained thousands of signatures.Black did not respond to a request for comment.

Tiangong -- 1(or.Heavenly Palace)space module(舱)is the first step toward China’s plan to build a space station around 2020.Its launch(发射)by China has upset some countries,which are asking why China did not add on to the International Space Station that has been in place since 1998. After all, the Americans,Russians,Europeans and Japanese are using one platform to experiment in space.
Questions have also been asked about China’s final purpose in space and suggestions made that there is something as unpleasant as the theme in a James Bond movie,in which Chinese-looking enemies were at the root of some evil(邪恶的)plot to control the world.
Chinese don’t see themselves that way, and never in history have they been flag-planting settlers.Most Westerners are educated in the adventures of the great European explorers,headed by Christopher Columbus and James Cook,and followed closely by the groups of culture egotists(自大者)with a mix of guns,gold and the Bible in their hands.
In comparison,Zheng He,the great Chinese sailing master,took groups of ships to Africa and the Middle East to promote goodwill, with gifts of chinaware and art.No flags claiming(宣称) possession of distant areas.But this is strange to Western society.
In this century,it is clear that space cannot be claimed by one nation.Yet advantage of technology in space does seem to be on some minds.Former US president Ronald Reagan caused shocks and worries with his Star Wars program.So when China shot down its own satellite as a test in January 2010 there were anxieties in the West about Star Wars 1ike scenario(剧本)becoming reality in the near future.
【小题1】The launch of Tiangong -- 1 __________.
A.is appreciated by countries like the USA and Japan |
B.will bring trouble to the western countries in space |
C.is part of China’s plan to set up a station in space |
D.will help China be a member of the Space Station |
A.are competing against one another in space wars |
B.feel anxious about China’s setting up a space station |
C.are cooperating to compete against China in space |
D.have warned the world of China’s final purpose |
A.to tell people China’s will never be enemies of world peace |
B.to compare him to the great European explorers like Columbus |
C.to indicate that he is the pride of the Chinese people |
D.to show that the Chinese people are as great as other peoples |
A.China’s shooting down its satellite made the scenario become reality |
B.some countries are trying to be ahead of the others in space exploration |
C.China will be in control of the world if she starts space exploration |
D.if a nation has a better technology in space,it will start a star war |

An 11-year-old boy who has been compared to Spanish Impressionist (
印象派画家), the great Pablo Picasso, is holding his first exhibition at Llangollen’s Gardening Show this weekend.
Hamad al-Humaidhan, who was born in Kuwait but now lives in Bath, Britain, had no previous knowledge of art history when he first picked up a brush.
But he began to paint his favourite football player, Cristiano Ronaldo, using Picasso’s trademarks (
标志) —bright colours and impressionistic forms.
His father said, "I’ve got lots of books about Picasso and I showed them to Hamad but he didn’t know anything about Picasso —it’s just naturally the way he sees it and he just loves to paint."
His first painting of Ronaldo, done when he was just nine, was sold at auction (
拍卖) in Bath for £650, which drew the attention of local art businessman Steve Turner. "A colleague sent me some pictures of Hamad’s work and I just couldn’t believe the size of it and how the colours blended (融合) together," he said. "He had talent and I thought Picasso had been reborn.""I’ve shown his work to private art collectors. They liked them very much and everyone was eager to buy, so the first six paintings have been snapped up. I bought two of them myself. The next set of his works will go on show for the first time at Llangollen, which will be the first opportunity for the public to see his amazing talent."
Hamad enjoys maths at school but ranks painting higher. "I think I prefer painting! It makes me relaxed and when I feel tired I just pick up a paint brush," he said. "I just close my eyes and see how it’s going to look and then I just paint it —I paint every day. I just love the colours and I want people to enjoy my paintings."
Now Hamad is nervously waiting for the opening of his exhibition.
【小题1】What is the text mainly about?
【小题2】A.Hamad’s painting exhibition.
B.Hamad and his talent for painting.
C.The popularity of Hamad’s works.

In Canada and the United States, there is a new group of children called “satellite kids”, who live in one place but whose parents live in another place.
Asians are immigrating to Canada and the United States in larger numbers than ever before.Most Asians immigrate because they believe that they can give their children a better education in the West.In Asia, especially in China, Japan, and Korea, it is difficult to go to university.Students must first pass the strict national examination.However, in Canada and the United States, it is easy to go to university, and anyone who wants to go can go.As a result, Asian parents decide to leave their countries so that their children can go to university.
The problem is that when Asians arrive, they discover that finding a job and making money are more difficult in the West than in the East.Also, they find that they are very lonely, and that they miss their homes.Because of these two reasons, most Asian parents decide to go back to work while their children study in the West.Therefore, these children become “satellite kids”, and most of their parents do not know how sad it is to be a “satellite kid”.
Only until now are Canadians and Americans discovering the “satellite kid” problem.Because these children do not speak English and because their parents are not there to take care of them, they are often absent from school.To be a “satellite kid” means to grow up in a country where you know you are different and where you cannot make friends because you do not speak English well.Also, it means to grow up lonely, because your parents are elsewhere.What these “satellite kids” will probably say to their parents is that it’s better to have parents around than to have a university education.
【小题1】Some Asian parents send their kids abroad because ________.
A.they hope their children may easily find a job there |
B.the kids may not be accepted by universities in their own countries |
C.all foreign universities are better than the ones in their own countries |
D.the kids want to improve their English and make foreign friends |
A.without patents |
B.living abroad alone |
C.with university education |
D.speaking no English |
A.want to leave their own country |
B.want them to go to university |
C.return to their countries to work |
D.want them to be independent |
A.Parents want better education for their kids. |
B.Parents feel lonely and miss their families. |
C.Canadians and Americans begin to notice the “satellite kids” problem. |
D.Kids in foreign countries alone are badly in need of care from family. |
