Read the following article and select the best answer. Article: There are new findings that not enough sleep may cause people to gain weight.Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger. In one study,researchers in the United States examined information on more than 1000 people.The people had taken part in a long-term study of sleep disorders. Some people slept less than five hours a night.They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours.And they had 15 percent less of the hormone leptin.Experts say ghrelin helps make people feel hungry;leptin makes you feel full. The scientists say these hormonal changes may be a cause of obesity in Western societies.They note the combination that limitation is common and is widely available. The results were not affected by how much people exercised.People who are awake longer have more time to burn energy.But the researchers say loss of sleep may increase hunger especially for high-calorie foods,so people gain weight.It seems that,for survival,the body may be designed to store more fat during times with less sleep. Researchers from Stanford University in California and the University of Wisconsin did the study.They found that the best amount of sleep for weight control is 7.7 hours a night. The Public Library of Science published the findings in its journal Medicine.Internet users can read the full study,free of charge,at plos.org.

Read the following article and select the best answer. Article: The months and years went by. I had been Joe's _ for four years. One evening, Joe and I were sitting in the village inn. A stranger came in, a big, tall man, with heavy eyebrows. The man had large, very clean white hands. To my surprise, I recognized the man. I had seen him at Miss Havisham's many years before. He had frightened me then. He frightened me a little now. 'I think there is a blacksmith here----name of Joe Gargery,' the man said in his loud voice. 'That's me!' Joe answered. He stood up. 'You have an apprentice, known as Pip,' the stranger went on. 'Where is he? ' 'Here!' I cried, standing beside Joe. 'I wish to speak to you both. I wish to speak to you privately, not here,' the man said. 'Perhaps I could go home with you.' We walked back to the workshop in silence. When we were in the sitting room, the man began to speak. 'My name is Jaggers,' he said. 'I am a lawyer in London, where I am well-known. I have some unusual business with young Pip here. I am speaking for someone else, you understand. A client who doesn't want to be named. Is that clear?' Joe and I nodded. 'I have come to take your apprentice to London,' the lawyer said to Joe. 'You won't stop him from coming I hope?' 'Stop him? Never! ' Joe cried. 'Listen, then. I have this message for Pip. He has ---- great expectations!' Joe and I looked at each other, too surprised to speak. 'Yes, great expectations' Mr. Jaggers repeated. 'Pip will one day be rich, very rich. Pip is to change his way of life at once. He will no longer be a blacksmith. He is to come with me to London. He is to be educated as a gentleman. He will be a man of property.' And so, at last, my dream had come true. Miss Havisham----because Mr. Jaggers' client must be Miss Havisham----had plans for me after all. I would be rich and Estella would love me! Mr. Jaggers was speaking again. 'There are two conditions,' he said, looking at me. 'First, you will always be known as Pip. Secondly,' Mr. Jaggers continued, 'the name of your benefactor is to be kept secret. One day, that...

Read the following article and select the best answer. Article: "I can't live without my mobile phone!" is what I often hear people say as they talk about how mobiles have become an essential part of their lives. The all so common sight of heads bent, eyes staring at mobile screens and fingers busy tapping away repeats itself across major cities around the world. Whenever there is a moment to spare while on the train, taxi or waiting in a queue, people busy themselves with their mobile phones. Some people believe our unhealthy obsession with mobile phones is destroying how we appreciate the little things in life or miss the moments that matter. The truth is that technology overall should be seen as just a tool to improve our lives. Mobile phones have certainly had a great influence on our lives, but I truly believe it is for the better. It's changed the way we communicate, whether for work or play. We are now less constrained by time and geographical location. With my mobile phone, I can dial into conference calls while stuck in a traffic jam, or reply to urgent e-mails while on the go. I can send a text message or share photos and videos with friends who aren't living in the same country. My phone calendar keeps my life organized, and even Facebook, Twitter, and instant messaging are now accessible from mobile phones! The mobile revolution isn't just changing the lives of urbanities like myself. I know of a young Bangladeshi woman named Shompa Akhter who is crazy about fashion and design. She dreamt about starting her own business and she did just that, opening a shop in Kushtia featuring her own creations. Dealing with supplies in different towns was a problem for Shompa --- purchase orders had to either be hand delivered or mailed out to supplies. Shompa also found it tough publicizing her business to potential customers outside her town. But once she learnt to operate the mobile phone, she was addicted. The 25-year-old businesswoman now stays in touch easily with her suppliers. Mobile e-mail is a blessing in her life. Who would have thought that mobility could...
