A new planet-hunting technique has detected the most earth-like planet yet around a star other than our sun, raising hopes of finding a space rock that might support life, astronomers reported recently. "This is an important discovery to answer the question 'Are we alone?'" said Michael Turner of the National Science Foundation. "The team has discovered the most earth-like planet yet, and more importantly, has proved the power of a new technique that is sensitive to detecting planets that are fit for people to live on," Turner said in a statement. In the last decade, astronomers have detected more than 160 planets moving around stars outside our solar system. Most of these have been gas giant planets like Jupiter, which are unfit for life. But an international team has detected a cold planet about 5.5 times more massive than the earth -- still small enough to be considered earth-like -- moving around a star about 20,000 light years away, close to the center of the Milky Way. To find this new planet, the team used a technique called gravitational microlensing . When a planet is circling the closest star, the planet's gravity can add its own signature to the light. This kind of light signature was observed on July 11 by a group of telescopes in a project known as OGLE, short for Optical Gravitational Lensing Experiment. "The main advantage of microlensing is the signals for low-mass planets: They're not weak signals. They're just rare," Bennett of the University of Notre Dame in Indiana said by telephone. "If there happens to be a straight line between a foreground star with its planet and the background source star, then you're able to detect that planet." Which of the following statements is NOT true according to the passage? A) The signals coming from low-mass planets are too weak to be noticed. B) Most of the discovered planets are not fit for people to live on. C) If a star with its planet happens to be in line with the source star, then the planet can be found. D) The power of the new technique is proved by the discovery of the earth-like planet.

it tastes just chicken Away from home, eating is more than just a way to keep your stomach full.It is a language all its own, and no words can say, "Glad to meet you ...glad to be doing business with you ..." quite like sharing a meal offered by your host. Clearly, mealtime is not the time for you to say, "Thanks, but no thanks." Acceptance of the food on your plate means acceptance of host, country, and company.So, no matter how difficult it may be to swallow, swallow.Or, as one experienced traveler says, "Travel with a cast-iron stomach and eat everything everywhere." Often, the food offered represents proudly your host country's eating culture.What would Ataiericans think of a French person who refused to take a bite of homemade apple pie or sirloin? Our discomfort comes not so much from the thing itself; it comes from our umamiliarity with it.After all, an oyster has remarkably the same look as a sheep's eye; and a first look at a lobster would remind almost anybody of a creature from a science fiction movie, not something you dip in butter and eat.By the way, in Saudi Arabia sheep's eyes are a famous dish and in parts of China it's bear's paw soup. Can you refuse such food without being rude? Most experienced business travelers say no, at least not before taking at least a few bites.It helps, though, to slice any item very thin.This way, you minimize the taste and the reminder of where it came from.Or, " Swallow it quickly, " as one traveler recommends."I still can't tell you what sheep's eyeballs taste like." As for dealing with taste, the old line that "it tastes just like chicken" is often thankfully true.Even when the "it" is really rat or snake. Another useful piece of advice is not knowing what you are eating.What's for dinner? Don't ask. Avoid glancing into the kitchen or looking at English-language menus.Your host will be pleased that you are eating the food he offers, and who knows? Maybe it really is chicken in that soup. One may say "It tastes just like chicken." when _ . A) showing respect for chicken-loving nations B) greeting people with different dieting habits C) evaluating chefs at an international food festival D) getting someone to try a visually unpleasant meal

Ques:Parents all struggle to get children to understand that money doesn't grow on trees, wanting them to be responsible, work hard and learn to save a few bucks. But these lessons are among the most difficult to teach. Enter KidZania, an internationally praised and truly unique children's theme park, that makes life a little easier for parents. KidZania is not a traditional theme park in almost any sense of the word -- there are no roller coasters or merry-go-rounds in sight. There are, however, plenty of attractions and activities that will keep children busy, active, engaged and excited all day. What makes it so much fun is that it's a kid-sized city -- complete with restaurants, banks, grocery stores and hospitals -- where the kids get to be adults, doing the things most of us do on any normal day. They start by picking one of nearly 100 "careers" and learning about it. Then, they put on their uniform and are ready to work and earn KidZania dollars ("Kidzos"). Most activities are universal but some are localized to reflect the distinct flavors and personality of the country and region where the park is located and to keep it real for the kids. Kids get paid for every job they do, which helps them explore the mysteries of managing money. Kidzos in hand, they can spend it or save it. If they run short of money, they'll have to find a way to earn some. Each KidZania city is planned in amazing detail, even including real world brands that help sponsor the city and keep it running. I was a little wary of all the popular corporate logos, but the brands weren't pushed at all. They are there to reinforce the "real city" feeling by mixing it with things kids recognize. KidZania employs senior citizens who give the park a homey feel and help put children at ease. Management also employs the disabled, whether blind, deaf or wheelchair-bound. Besides making for a more realistic city, this teaches children about those with different abilities and gives them an opportunity to spend time with people they might otherwise have... Which of the following might be the best title of the passage? A) Children do part-time jobs at a theme park B) A theme park pushes kids to be grown-ups C) KidZania theme park makes adults' life easier D) Kids get to 'be' adults at KidZania theme park
