Question: Article: Reseachers at the University of Kansas say that people can accurately juage 90 percent of a stranger's personality simply by looking at the person's shoes."Shoes convey useful information about their wearers,''the authors wrote in the new study published in the Journal of Research in Personality. Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone's shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study's participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire. Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,"practical and functional'' shoes were generally worn by more "pleasant" people,while ankle boots were more linked with ''aggressive'' personalities.The strangest of all may be that those who wore' 'uncomfortable looking" shoes tend to have "calm" personalities.And if you have several pairs of new shoes or take extreme care of them,you may suffer from "attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal types wearing "shabbier and less expensive" shoes. The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities.
Answer: People know little about their personalities.

Question: Article: A window is more than just an opening that you can see through. It can affect the way a building looks,how much energy a building USES and even how you feel. Scientists are now working on ncw technologies to create"smart windows". Unlike normal windows,high-tech smart windows can change from clear to dark and back again with the touch of a button --or even automatically as the outside light changes. Smart windows have the power to make the world a cleaner and more comfortable place. Instead of turning on air conditioners ,people could simply _ the windows in a building's empty rooms. With the rooms less bright,they would stay cool,and people would save energy and money at the same time. That's why smart windows are so exciting. Says Claes Granqvist. He's a professor of physics at Uppsala University in Sweden. If you think that you don't care much about windows,you should think again,Granqvist says. Most people who live in developed countries spend about 90% of their time inside buildings and cars. You might spend even more time than that indoors during the winter if you live in a cold climate. Imagine then what it would be like if there were no windows. You'd have no idea what's going on outside. So,the light of the nature is important for improving the way people feel when they stay indoors. The development of smart windows could mean that a lot of air-conditioning systems may no longer be needed. "In the future," Granqvist says "our buildings may look different."
Answer: They can change automatically or by pressing a button.

Answer: About the smart windows.which of the following is NOT true?

Question: Article: A WOMAN walks into a small stall and eats a cheap bowl of instant noodles, paying 1,500 won. Then she moves into a Starbucks coffee shop, where she drinks a cup of mocha, paying 4,300 won. Surprised? This is the typical behaviour of South Korean young women. They are called "denjang girls". The term "denjang girls" referred to female shoppers who would eat cheaply and then _ to be seen drinking a cup of expensive coffee. Now it has grown to a new army of women in their 20s who look smart, rich but are actually buying luxuries they probably can't afford. Internet users created the term when debating the popularity of Starbucks coffee among South Korean women. In prefix = st1 /South Korea, the coffee costs, on average, over a dollar more than inJapanand theUS. Despite the higher price, Starbucks sales inSouth Koreaincreased from 72.1 billion won in 2004 to 91.2 billion won in 2005. Ahn Ji-Yoon, a student at Yonsei University in Seoul, says she can spend two hours surfing the web for discounts on skin cream and dinner. Yet she would think nothing of spending US$550 on a Gucci bag. Girls like Ahn live by extremes - hunting for bargain items while spending heavily on "necessary luxuries".
