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 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 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(創(chuàng)新的)research.”

London’s newest skyscraper (摩天大樓) is called the Shard and it cost about 430 million pounds to build. At a height of almost 310 metres, it is the tallest building in Europe. The Shard has completely changed the appearance of London. However, not everyone thinks that it is a change for the better.
The Shard was designed by the famous Italian architect Renzo Piano. When he began designing the Shard for London, Piano wanted a very tall building that looked like a spire (尖頂). He wanted the glass surfaces to reflect the sky and the city. The sides of the building aren’t regular. So the building has an unusual shape. It looks like a very thin, sharp piece of broken glass. And that is how the building got the name: the Shard. Piano says that the spire shape of the Shard is part of a great London tradition. The shape reminds him of the spires of the churches of London or the tall masts (桅桿) of the ships that were once on the river Thames.
The Shard has 87 floors. At the top, there is an observatory. At the moment the building is empty, but eventually there will be a five-star hotel. There will also be top quality restaurants, apartments and offices.
Before building work began, a lot of people didn’t want the Shard though the plans were approved. Now they are still unhappy about the Shard. Some critics say that such a tall skyscraper might be good in a city like New York, but not in London. They say that the best thing about the Shard is its spire shape. But that is the only thing. There is no decoration, only flat surfaces. The Egyptians did that 4,500 years ago. They also think the Shard is too big for London. It destroys the beauty of the city.
Other critics don’t like what the Shard seems to represent. They say that the Shard shows how London is becoming more unequal. Only very rich people can afford to buy the expensive private apartments and stay in the hotel. But the people who live near the Shard are among the poorest in London. So the Shard seems a symbol of the division in society between the very rich and the poor.
The Shard now dominates the London skyline. It is not certain, however, that ordinary London citizens will ever accept it as a valuable addition to the city.
1. London’s newest skyscraper is called the Shard because of ______.
A. its cost B. its size
C. its shape D. its height
2.When he designed the Shard, Piano wanted it to ______.
A. change London’s skyline
B. inherit London’s tradition
C. imitate the Egyptian style
D. attract potential visitors
3.Some people criticize the Shard for the following reasons except that_______.
A. it has a spire shape
B. it is too tall a building for London
C. the design of its surfaces is somewhat outdated
D. it ruins the beauty of London
4.The critics who refer to social division think the Shard ______.
A. is only preferred by the rich
B. is intended for wealthy people
C. is far away from the poor area
D. is popular only with Londoners
5.Which would be the best title for the passage?
A. The Shard: Cheers and Claps
B. The Shard: Work of a Great Architect
C. The Shard: New Symbol of London?
D. The Shard: A Change for the Better?

The Elephant and the Fly
An elephant was standing and picking leaves from a tree. A small fly came,flying and buzzing (嗡嗡叫) near his ear. The elephant waved it away with his long ears. Then the fly came again, and the elephant waved it away once more.
This was repeated several times. Then the elephant asked the fly, “Why are you so restless and noisy? Why can’t you stay for a while in one place? ”
The fly answered, “I am attracted to whatever I see, hear or smell. My five senses pull me constantly in all directions and I cannot resist them.What is your secret? How can you stay so calm and still?”
The elephant stopped eating and said, “My five senses do not rule my attention. Whatever I do, I get involved in it. Now that I am eating, I am completely absorbed in eating. In this way I can enjoy my food and chew it better. I rule and control my attention, and not the other way around. So when you are in charge of your five senses and attention, your mind will become calm, too.”

Social Practice
Social practice has been more and more popular in schools. Senior school students are asked to enter society and get some ideas of it. Surely, social practice has many advantages. Firstly, social practice can offer students a chance to contact society and meet different kinds of people. In this way students can gain some precious social experience, which will be useful to their future career. Secondly, students can apply what they have learned in class to practical work, thus knowing themselves more clearly. Thirdly, social practice can bring them some financial reward and make them more independent of their family.
However, some problems may arise if no correct guidance is made. For example, some students get overly interested in social practice and want to work full-time and earn more money, thus neglecting their studies. And some students are likely to get in touch with the dark side of society, which will affect their future values.
In order to carry out social practice smoothly, students should first know their objective. They should put their studies in the first place and see social practice just as a useful supplement(補充), so they ought to try to strike a balance between social practice and their studies.
