Emily and her boyfriend had just had a fight. She felt alone and hopeless. Then she went into the kitchen and grabbed what she needed before going back up to her room quietly. She switched on the TV and started eating...and eating...for hours, until it was all gone. What Emily didn't know at the time was that she was suffering from an illness called binge-eating disorder(BED) . For years, Emily didn't tell anyone what she was doing. She felt ashamed, alone, and out of control. Why don't famous people confess to BED, as they do to _ ? It's simple: There's a stigma involved. "Overeating is seen as very bad, but dieting to be skinny is seen as positive and even associated with determination," says Charles Sophy, a doctor in Beverly Hills , California. "Some parents or friends may look at a teen with BED and think, 'Oh, a good diet and some will-power will do the trick.' But that's not true," says Dr.Ovidio Bermudez , a baby doctor at the Eating Recovery Center in Denver. "Eating disorders are real physical and mental health issues; it's not about willpower." The focus in treating BED shouldn't be on weight, because as with all eating disorders, the behaviors with food are a symptom of something deeper. Like most other diseases, genetics may play a big part in who gets BED and who doesn't. If you have a close relative with an eating disorder, that means you're more likely to develop an eating disorder of your own. Besides, many people with BED have tried at some point or another to control it by going on a diet, but paying more attention to food doesn't help. And it might even make things worse, like it did for Carla, who's 15 now and is recovering from BED. "My parents would always tease me about my weight, so when I was 14, I went on a very restrictive diet," she says. When you can't have something, you only want it more, so every time Carla would have a bite of something that wasn't allowed on her strict diet. She would quickly lose control and binge . According to Dr. Ovidio Bermudez, people with BED _ . A) just need a lot of willpower B) can recover with a good diet C) can recover with the help of others D) need to deal with their health problems

Bali is a tiny island that is part of Indonesia today. It is a pretty island that has many mountains and a pleasant climate. For a long time, Bali was cut off from much of the world. The people of Bali were happy and had a peaceful life. They were not allowed to fight. At one time there had been terrible wars on Bali. Then the people decided it was wrong to fight or have wars. They made rules to keep apart those people who wanted to fight. Bali was divided into seven small kingdoms. The land around each kingdom was kept empty, and no one lived there. Since the kingdoms did not share the same borders , the people could not fight about them. On Bali, even children were not allowed to fight. If two children started a fight over a toy, someone separated them. When two boys argued, they would agree not to speak to each other. Sometimes they did not talk together for months; this gave the boys a chance to forget their anger. Families who were angry with each other also promised not to speak. Their promise was written down, and the whole village knew about it. If they broke their promise, they had to offer gifts to their gods. Bali is an island belonging to _ . A) Europe B) Africa C) Asia D) America

Q: If you have a fever, headache and runny nose, you might go to Google and type in the words "flu symptoms" to see whether you've come down with the disease. Google knows that you might do something like that, and it also knows which state you're in if you are in the United States. Now, it's putting that information together in a tool that could find out flu outbreaks faster than traditional systems currently in use, according to CNN report. It is called Google Flu Trends. "What's exciting about Flu Trends is that it lets anybody---doctors, health officials, moms with sick children---learn about the current flu activity level in their own state based on the data that's coming in this week," said Jeremy Ginsberg, the lead engineer who developed the tool. The tool operates on the idea that there's likely to be a flu outbreak in states where flu-related search terms are currently popular. To test the accuracy of the data, Google compared its figures against statistics filed over the past five years by the US Centers for Disease Control. It has a network of 1,500 doctors across the US who provide weekly reports on the number of patients complaining of flu-like symptoms. "We found we could highly accurately estimate what the flu activity levels would be in those years," Ginsberg said. They also found that the Google statistics, which can be gathered daily, were up to two weeks ahead of the government's data. The government's data took time to collect because it came from so many doctors. The ability to speed up the response of health services could prove invaluable when a serious outbreak happens. The results of Google's comparisons with official health statistics will be published in the science journal Nature. Google hopes to extend the service to other countries, and may in time include other illnesses. At present, the flu data is given for each of the 50 American states. The company says there are no privacy issues involved as the trends are gathered through... Which is NOT true according to the passage? A) The government's data mentioned in the passage came from a network of 1,500 doctors across the US. B) Google Flu Trends' reports can be one or two weeks ahead of those by the government. C) Google Flu Trends' estimates prove quite accurate and reliable. D) Anyone around the world can enjoy the service of Google Flu Trends.

While Jennifer was at home taking an online exam for her business law class, a monitor a few hundred miles away was watching her every move. Using a web camera equipped in Jennifer's Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down? In the battle against cheating, this is the _ and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven't just searched the Internet to get the right answers. Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance. Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone number they once used. Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating. Some programs can find out possible cheaters by _ . A) checking the question answering speed B) producing a large number of question C) scanning the Internet test question D) giving difficult test question
