No more batteries, no more characters and no more wires．This is the future promised by “wireless power”, a means of broadcasting electricity through the air to laptops, Pods and other gadgets（小器具）without the need for cables and sockets（插座）．

  Wireless lighting, audio speakers and digital picture frames are expected to be among the first commercial products exhibited in Las Vegas this week at the International Constumer Electronics Show, the world’s biggest tradeshow．

Experts believe this is just the beginning and eventually wireless electricity could do for battery life what WiFi （局域网）did for the Internet．In a world without wires, laptop users in cafes and airport terminals（终点站）would be inside an “electricity hotspot” and no longer have to_delve an awkward located socket．

“You’d be able to buy a desk that charged any gadget placed on it, or power any PC you put on top,” said James Holland , editor of gadgets website Electric pig．co．uk “If each room had wireless power, you’d know that once you walked through the front door your mobile would start charging up---- even while still in your bag or pocket．You’d never need to hunt for the right charger again．”

Among the companies showcasing the ambitious technology at CES is Power Beam．Its system turns electricity an invisible laser, then beams （传播）it, as heat, across the room to a solar cell that converts it back into electricity．

David Graham ,the co-founder of  Power Beam, said: “We’re going to delete the word ‘recharge’ from the English dictionary．If your cell phone is recharging on your desk all day, you won’t be thinking about it．” The Silicon Valley company can currently use a laser to generate about 1．5 watts power to a solar cell 10 meters away． This would be enough to power an electronic speaker or small LED（二极管） lights, but not enough to operate a laptop, which requires about 30 to 50 watts．However, Graham said that the technology could comfortably be scaled up （提高）.

Power Beam insists its laser does not lead to a risk to users’ health because it is simply moving heat from one place to another．Graham said that, if someone walked throe the beam, it would shut down within a thousandth of second, then restart once the path is clear．The technology also promises because it would only power products when needed．

　　One hundred new bookstalls that will sell newspapers as well as books have been making their debut on city streets since Saturday morning.

　　The newsstands are part of the city's efforts to improve the appearance of streets and neighborhoods. The newsstands' design, featuring large glass window, will help the customers to see what is on sale at a glance.

　　An electrical screen on the newsstands will announce immediately the arrival of the latest papers. The newsstands will also help collect utility fees. There will be 1000 newsstands by the end of the year. The newly formed Oriental Books and Papers Service Co. Ltd will manage the stalls. According to sources from the company, over 80 percent of the people hired to operate the stands will be recruited from laid-off workers. This means the project will help ease the city's unemployment pressure, sources said.

　　All recruited will undergo a training programme and be glad in green uniform. Municipal Vice-part Secretary Gong Xueping said the installation of the 100 stands was just the first step towards the objective of setting up 1000 stands in the city by the end of the year.

Honesty may well be the policy, but it often deserts us when no one is watching, psychologists report today. Experiments with an honesty box to collect payments for hot drinks show that people are better at paying up when under the gaze of a pair of eyes. The surprise was that the eyes were not real, but photographed.

Researchers at Newcastle University set up the experiment in secret. They attached a poster to a cupboard of mugs above an honesty box alongside a kettle, with tea, coffee and milk. Over 10 weeks, they alternated each week between images of eyes and pictures of flowers.

Dr. Bateson, a behavioral biologist and leader of the study, said that even though the eyes were not real they still seemed to make people behave more honestly. The effect may arise from behavioral characteristics that developed as early humans formed social groups that increased their chances of survival. Individuals had to co-operate for the good of the group, rather than act selfishly.

“If nobody is watching us it is in our interests to behave selfishly. But when we think we’re being watched we should behave better, so people see us as co-operative and behave the same way towards us,” Dr. Bateson said.

“We thought we’d get a slight effect with eyes, by it was quite striking how much difference they made. Even at a subconscious level, it seems people respond to eyes, and that might be because eyes send a strong biological signal we have evolved(进化) to respond to.”

The finding, which researchers believe sheds light on our evolutionary past, could be turned to practical use. The psychologists say images of eyes could promote ticket sales on public transport and improve monitor systems to prevent antisocial behavior.

We find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming（把…按能力分班）pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade!

　　Besides, it is rather unreal to grade people just according to their intellectual (智力的) abilities. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning.

　　In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with personal problems as well as how to think, to make decisions, to analyze and evaluate, and to communicate effectively. The pupils learn from each other as well as from the teacher.

　　Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments, and they can do this at their own speed. They also have some library, and we teach them the skills they need in order to do this effectively. And expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.

1. Group work provides pupils with the opportunity_________.

　　A. to develop academic abilities                 　　 B. to learn to teach.

　　C. to do some experiments                        　　 D. to learn to be capable organizers.

2. By "held back" in the first paragraph the author means _________.

　　A. drawn to their studies                           　　     B. prevented from advancing

　　C. made to remain in the same classes         　　 D. forced to study in the lower classes

3. In the passage the author's attitude towards " mixed-ability teaching" is ________.

　　A.questioning               B. approving  　　     C. objective 　　 D. critical

4. The author's purpose of writing this passage is to _________.

　　A. offer advice on the proper use of the library

　　B. emphasize the importance of appropriate formal classroom teaching

　　C. argue for teaching bright and not -so-bright pupils in the same class

　　D. recommend pair work and group-work for classroom activities

5. The author argues that a teacher's chief concern should be the development of the student's _____.

　　A. total personality              　　                   B. intellectual ability

　　C. learning ability and communicative skills        D. personal qualities and social skills
