Ques: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: According to James Holland,we know that _ . Yes or no, is the answer "gadgets can be charged in a loom with wireless power"?

Ans:No

Ques:Article: "The world has never been a better place to live in," says science writer Matt Ridley, "and it will keep on getting better." Ridley's critics have accused him of his views on climate change and the free market. Yet Ridley, 54, sticks to his guns. "It is not mad to believe in a happy future for people and the planet," he says. Ridley, who's been a foreign correspondent, a zoologist, an economist, and a financier, brings a broad view to his sunny outlook. "People say I'm crazy to claim the world will go on getting better, yet I can't stop myself," he says. Read on to see how Ridley makes his case. Compared with 50 years ago, when I was just four years old, the average human now earns nearly three times as much money, eats one third more calories, and can expect to live one third longer. In fact, it's hard to find any region of the world that's worse off now than it was then, even though the global population has more than doubled over that period. City citizens take up less space, use less energy, and have less impact on natural ecosystems than country livers. The world's cities now contain over half its people, but they occupy less than 3 percent of its land area. Urban growth may worry environmentalists, but living in the country is not the best way to care for the earth. The best thing we can do for the planet is build more skyscrapers. The rich get richer, but the poor do even better. Between 1980 and 2000, the poor doubled their consumption. Nigerians are twice as rich and live nine more years. The percentage of the world's people living in poverty has dropped by over half. The United Nations estimates that poverty was reduced more in the past 50 years than in the previous 500. Question: Ridley's attitude toweards the human future is _ . Yes or no, is the answer "optimistic"?

Ans:Yes

Ques:Article: Handshaking, though a European practise is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other's hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other. "Let's shake (hands) on it" sometimes means agreement reached. Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or-her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly- There is generally a misunderstanding among the Chinese that westerners are usually open and straighforward, while the Chinese are rather reserved in manner. But in fact some people in western countries more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you. Question: In the old days in Europe, people put out their unarmed hands to each other _ . Yes or no, is the answer "to show friendliness"?

Ans:Yes

Ques:Article: Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China. This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund. The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950s, there were over 4,000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species. Sixty-six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves. "Breeding has damaged the quality of the species," said Pei Enle, deputy director of the Shanghai Zoo. To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts and can hunt wild animals by themselves at the African base. "South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in," said Lu Jun, office director of the National Wildlife Research and Development Centre. "We tried in Fujian Province, but it was not successful as there was not a complete eco-chain and there was a lack of space." The tigers should return to China in 2009 when the reservations in Fujian are ready. Question: How is the programme of sending several tigers to South Africa getting on? Yes or no, is the answer "Some of the tigers are already on the road to recovering their natural skills."?

Ans:
No
