Q: Article: We like people who look like us, because they tend to have personalities similar to our own. And, a new study suggests, the longer we are with someone, the more similarities in appearance grow. Researchers set out to study why couples often tend to look like one another. They asked 11 male and 11 female participants to judge the age, attractiveness and personality of 160 real-life married couples. Photographs of husbands and wives were viewed separately, so the participants didn't know who was married to whom. The test participants rated men and women who were actual couples as looking alike and having similar personalities. Also, the longer the couples had been together, the greater the similarities. The researchers guess that the sharing of experiences might affect how couples look. The idea that there is a connection between appearance and personality might seem strange at first, but there could be biological reasons for a link, said study member Tony Little from the University of Liverpool in England. "The face displays our emotions and over time, emotional expressions may become written in the face," Little told Live Science. For example, someone who smiles a lot may develop lines and muscles that are suggestive of someone who is happy. Other studies have shown that partners who are genetically similar to each other tend to have happier marriages. The new study indicates that people have different features when using facial appearance to make decisions about someone's personality, and that the particular cues  focused on change from face to face. Vital to the decision, however, are eyes and smiles. "Smiles are important social cues that may tell us whether or not someone is friendly, and eyes are also a traditional focus of attention," Little said. Overall face shape can be important too. For example, the combination of large chins and strong brow ridges can create an impression of disagreeableness and being unwilling to cooperate, Little said.

Q: Article: Mary Jean Price Walls graduated second in her class in 1950.She had high hopes when she applied to a local college,Southwest Missouri State College.But after sending off her application,she spent months waiting for a reply.It never came. Worse than simply being denied admission ,the school didn't reply to her at all.It wasn't a matter of her school records,but of her skin color:Wallsis African American,and in those days,that fact alone closed a lot of doors. "I was sad and I was hurt,"Walls toldABCNews."I did not expect the skin color would affect my application.I thought I could go to university like other students." Four years later,the government declared that all schools should not discriminate against African Americans-- but it was too late for Walls.She'd moved on with her life, becoming a wife and a mother,and working as an elevator operator.She retired last year,at the age of 77. She stayed quiet about the unfairness she'd faced in Missouri State.Her son,Terry,went through school records and found that she'd been the first black student to ever apply to the college.Today,four percent of the Southwest Missouri State College body is African American--including Terry. Although it's too late for Missouri State to change the past,the school is awarding Walls with an honorary degree from the school.While she knows it's too late for herto change the course of her own life with the degree,it's a chance for her to show her family that Missouri State has changed in the last 60 years,and there's not a single door closed to them anymore.

Q: Article: Researchers and many scientists are concerned that the earth's climate and atmosphere are becoming warmer than they should be. What scientists do agree on is that the temperature will continue to increase if measures are not taken to reduce pollution and emission   from cars and factories. It is widely agreed that oil and coal create greenhouse gases when they are burned to produce heat or power. These emissions include carbon dioxide, which is the cause of most of the global warming problem. The loss of the trees in many areas is making the problem worse, because trees and plants absorb carbon dioxide and release oxygen. The fewer trees that are left standing, the less carbon dioxide can be absorbed. Scientists predict that the sea level will rise, ice caps   will melt, and some animals and plants will fail to survive because their habitat will disappear. There may be more deserts and less available farmland because of the dry ground, and there may be more storms and floods in many countries. Some countries, including the UK and the US, are taking steps to prevent the situation from becoming worse. There are programmes to educate citizens and students about the situation and recycling waste is becoming more common. New guidelines are being introduced to try to limit greenhouse gases from being produced by factories and businesses. Using more alternative energy sources is also a good way to prevent global warming. One thing that everyone can do is limit their use of energy every day, and you can do this no matter how old or young you are. Try to limit the unnecessary use of electricity and work to conserve energy every day.
