Article: No more batteries,no more chargers and no more wires.This is the future promised by "wireless power".a means of broadcasting electricity through the air to laptops,iPods and other gadgets without the need for cables and sockets . 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 Consumer Electronics Show,the world's biggest gadgets tradeshow. Experts believe this is just the beginning and that eventually wireless electricity could do for battery life what WiFi did for,the Internet.In a world without wires,laptop users in cafes and airport terminals would be inside an "electricity hotspot" and no longer have to delve an awkwardly 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 Eleetricpig.co.uk."If each room had wireless power,you'd know that once you walked through the front door your nmbile 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 ambitions technology at CES is Power Beam.Its system turns electricity into an invisible laser, then beams it as heat,across the room to a solar cell that conveys it back into dectricity. 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 of power to _ a solar.cell 10 meters away.This, sould be enough to power an electronic speaker or small LED 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 . Power Beam insists its laser does not lead to a risk to users' health because it is simply moving heat from one place... Question: What does the writer want to tell us in the passage? - A wireless instrument used for charging. - The only company to show the ambitious technology. - A means of broadcasting electricity to gadgets. - A new efficient energy.

Q: Read the following article and select the best answer. Article: Ogilvie the detective arrived. Both the Duke and Duchess were extremely nervous. The Duchess went to the door herself. The detective's piggy eyes surveyed her. His gaze moved on to sweep the spacious, well-decorated room, and the Duke. "Pretty neat set-up you've got."Ogilvie said slowly.

Her tone would have frightened anyone who knew her well. "You unspeakable blackguard! How dare you!" Ogilvie said nothing. But the Duke cut in, "It's no go, old girl, I'm afraid. It was a good try." Facing Ogilvie, he said, "What you accuse us of is true. I was driving the car and killed the little girl." "That's more like it," Ogilvie said, "now we're getting somewhere." The Duchess sank back into her chair. She asked, "What is it you know?" "I'll tell you, I got a curious nature. You and your wife drove home, you were driving, after a drink. Last night I saw you come in--through the basement, looking shaken, the pair of you. I got wondering why. Like I...
