Have you ever ''Googled'' yourself? More Americans are Googling themselves-and many are checking out their friends,co-workers and romantic interests,too. In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S.adult Internet users have looked for information about themselves through Google or another search engine.That is more than twice the 22 percent of users who did in 2002,but Pew senior research specialist Mary Madden was surprised the growth wasn't higher. "Yes,it's doubled,but it's still the case that there's a large number of Internet users who have never done this simple act of plugging their names with search engines,"she said. Americans under 50 and those With more education and income were more likely to self-Google--in some cases because their jobs demand a certain online persona.Meanwhile.Pew found that 53 percent of adult Internet users admit looking up information about someone else. celebrities excluded. Often,it's to find someone they've lost touch with.But looking up information about friends, s,colleagues and neighbors was also common. Although men and women equally searched for online information about themselves.women were slightly more likely to look up information about someone they are dating. In many cases,the search is just done to find someone's contact information.But a third of those who have conducted searches on others have looked for public records,such as bankruptcies and divorce proceedings.A similar number have searched for someone else's photo. Few Internet users say they Google themselves regularly-about three quarters of self searchers say they have done so only once or twice.And most who have done so consider what they find accurate. Pew also found that teens were more likely than adults to restrict who can see their profiles at an online hangout like Facebook or news Corp's MySpace. Why have many Internet users never made a try to Google themselves? A) Because they don't consider what they find accurate. B) Because they think it unnecessary to do so. C) Because they worry about their security online. D) It is not mentioned in the report.

Although Thomas Edison created the technologies behind three major 21st century industries electrical power,recorded music and movies--his greatest invention may have been the modern method of inventing.He basically came up with the modern system of research and development.Edison was not the only scientist doing research in his garage but someone who gathered around him a team of creative scientific minds.Edison's 1aboratories were the forerunners of Apple,Google and Microsoft. Yet for a11 his scientific gifts,he was no Steve Jobs or Bill Gates.He once said,"Anything that won' t sell,I don' t want to invent." But Edison,unlike Jobs or Gates,had no real sense of what the public wanted or how to change his discoveries into products that might sell.It took him years to understand that the phonograph was not a business tool but an entertainment invention.He helped create movies but resisted the idea that people might want to go into a theater to watch one. We chose Edison this year because we need his example now more than ever.Though we live in a time of great reformation,the U.S.is in danger of losing its advantage in science and technology.American investment in research and development has not increased as a percentage of GDP since the mid1980s,while the government' s share has been dropping.And this is at a time when China is rapidly increasing its money on research and development.The U.S.was once among the 1eading nations.Now it ranks near the bottom of the 23 nations that collect such data.We hope that Edison' s story might not only encourage reformation but also inspire more young Americans to study science and engineering. The author' s main purpose is to _ . A) inform US of the danger the USA is in B) get young Americans to study science C) be in honor of Edison for his contributions D) tell US how important Edison' s inventions are

Ques: One thing the tour books don't tell you about London is that 2,000 of its residents are foxes , which fled the city about centuries ago after developers and pollution moved in . But now that the environment is cleaner , the foxes have come home , one of the many wild animals that have moved into urban areas around the world . Several changes have brought wild animals to the concrete jungles . First of all , air and water quality in many cities has improved as a result of the 1970s' pollution control efforts . meanwhile , rural areas have been built up , leaving many animals on the edges of suburban areas . In addition , conservationists have created urban wildlife shelters . " The number and variety of wild animals in urban areas is increasing , " says Gomez Jones . One of the country's largest populations of raccoons now lives in Washington , D.C. , and moose are regularly seen wandering into Maine towns . Peregrine falcons dive from the window edges of buildings in the largest U.S. cities to hunt for pigeons . For peregrine falcons , cities are actually safer than rural areas . By 1970 the birds had died out east of the Mississippi because the DDT , a widely used poison to kill insects , had made their eggs too thin to support life . That year , Tom Cade began raising the birds for release in cities , for cities afforded abundant food in the form of pigeons and contained none of the peregrines' natural enemies . " Before they died out , some migrated to cities on their own because they had run out of natural habitats , " Cade says . " To peregrines , buildings are just like natural habitats . " He has released about 30 birds since 1975 in New York , Baltimore , Philadelphia and Norfolk , and of the 20 pairs now living in the East , half are originally born in the city . " A few of the young ones have gotten into trouble by falling down chimneys and crashing into window glass , but overall their adjustment has been successful . " . The passage is mainly concerned with _ . A) wildlife of all kinds returning to large cities to live B) falcons in New York , Baltimore , Philadelphia , and Norfolk C) moose running into glass doors of stores D) foxes returning to London
Ans: A
Ques: The food on the moon has come a long way from the freeze - dried bread to half - dried food. They have changed a lot in the past few years. And now US scientists want to grow vegetables in mini - greenhouses on the moon. Scientists say they are looking forward to a time when people on the moon or even Mars will be able to eat green and fresh vegetables. Paragon Space Development Corporation has shown people what it called the first step toward growing flowers - and finally food - on the moon. Paragon, which is a partner of NASA in experiments at the International Space Station, calls it a "Lunar Oasis " This is a closed greenhouse placed in a metal box. It is designed to safely land a laboratory plant on the moon surface, and protect it while it grows. The small greenhouse is to be sent up into space by Odyssey Moon Ltd, which takes part in the Google Lunar X Prize. This competition offers $ 20 million to any company which can send up, land and operate a lunar rover on the moon surface. Leaders of Paragon say future testing of the "Lunar Oasis" will be driven by Odyssey's flight schedule, which will not happen until 2012 at the earliest. When it is sent up, the greenhouse will have the seeds of cabbage inside it. Because they go from seed to flower in just 14 days, they can complete their life cycle in a lunar night. "Growing plants on the Moon or Mars seems so far away, but it is important that we do this research now," Paragon president Jane Poynter said. "It takes a long time to do a lot of research." What do we know about "Lunar Oasis" from the passage? A) It is made of wood by scientists. B) It is open for people who are on the Mars. C) It can carry different kinds of plants to the moon. D) It will protect plats to grow on the moon.
