Read the following article and select the best answer. Article: A villa designed to resist earthquakes with "self-healing" cracks in its walls, thanks to nanotechnology applications with self-healing polymers , is to be built on a Greek mountainside. The villa's walls will include special particles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material. The NanoManufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called "Intelligent Safe and Secure Buildings" (ISSB) is funded under the EU's Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, "What we're trying to achieve here is very exciting. We're looking to use polymers in much tougher situations than ever before on a larger scale." Monitors contained in the villa's walls will be able to collect vast amounts of data about the building over time. Wireless sensors will record any stresses and vibrations, as well as temperature, humidity and gas levels. The walls are to be built from new load-bearing steel frames and high-strength gypsum board. Prof Wilkins said, "If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape. If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. If the house falls down, we have got hand-held devices that can be used over the ruins to pick out where the embedded sensors are hidden to get some information about how the villa collapsed. Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue." Question: It can be inferred from the passage that tremor-resistant home _ . - is still being tried out - is already under construction - has been in wide use - will be put into wide use soon
is still being tried out

Read the following article and select the best answer. 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 _ . - a cell phone Can be powered only on a desk - gadgets can be charged in a loom with wireless power - a right charger is needed - each room should have wireless power
(Answer)
gadgets can be charged in a loom with wireless power

Question: Read the following article and select the best answer. Article: Before my first summer vacation at college, my roommate Ted asked to me to work with him on his father's farm in Argentina. The idea of spending two months in Argentine was exciting. Then I began having second thoughts. I had never been far from New England, and I had been homesick my first few weeks at college. What would it be like in a strange country? What about the language? The more I thought about it, the more the idea worried me. In the end I turned down the invitation. As soon as Ted asked somebody else to go, I began kicking myself. I had turned down something I wanted to do because I was scared, and had ended up feeling depressed. That unhappy summer taught me a valuable lesson out of which I developed a rule for myself: do what makes you anxious; don't do what makes you depressed. At the end of my senior year, I began to think about becoming a writer. But my professor was urging me to aim at teaching. I hesitated. The idea of trying to live by writing was a lot scarier than spending a summer in Argentina. Back and forth I went, making my decision, unmaking it. Suddenly I realized that every time I gave up the idea of writing, that downhearted feeling went through me. Giving up on what I really wanted to do depressed me. Right then I learned another lesson. To avoid that kind of depression meant having to bear a certain amount of worry and concern. When I first began writing articles, I was frequently required to interview big names. Before each interview I would get butterflies in the stomach and my hands would shake. One person I particularly admired was the great composer Duke Ellington. On the stage and on television, he seemed the very model of confidence. Then I learned Ellington still got stage fright. If the highly honored Ellington, who had appeared on the bandstand some 10,000 times over 30years, had anxiety attacks, who was I to think I could avoid them? I went on doing those frightening interviews. Then I realized to my astonishment that I was even looking forward to the interviews....
