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. Which of the following shows the right way in which lack of sleep causes weight gain? A) more ghrelin and less leptin-feeling hungry-eating more B) feeling hungry-eating more-more ghrelin and less leptin C) burning more energy-feeling hungry-eating more D) more leptin and less ghrelin-feeling full-less exercise

Q: The art of public speaking began in ancient Greece over 2,000 years ago. Now, twitter, e-mail, blogs and QQ chat offer approaches to communication-- but none can replace the role of a great speech. The spoken word can handle various important functions: persuading or inspiring, informing, paying tribute , entertaining, or simply introducing someone. Persuading is used in dealing with or _ different points of view. When the leaders met in Copenhagen in December, 2009, persuasive words from activities encouraged them to take former action. Inspirational speeches deal with emotions. They focus on topics and matters that are close to people' s hearts. Last year, during the fighting in Iraq, generals used inspiring speeches to prepare the troops for battle. Some speeches spread knowledge and deepen understanding. When the H1N1 flu was announced, the disease scared many people. Informtive speechs from World Health Organization (WTO) officials helped people to keep their panic under control so they could take necessary preventive measures. Sad events are never easy to deal with but a speech that pays tribute to the loss of a loved one and gives praise for their contribution can be comforting. Madonna's speech about Michael Jackson after his death showed the fact that he will continue to live on through his music. It's not only in world forums where public speaking plays an important role. It can also be helpful in the course of our own life. You may be asked to do a presentation at college or work to inform others about an area of great importance. On a more personal level, a friend may be upset and need comforting. Or you might be asked to introduce a speaker at a family gathering or to speak at a wedding, where your language will be needed to move people or make them laugh. Great speaking ability is not something we're born with. Even Barack Obama works hard to perfect every speech. What would be the best title for the passage? A) Tips of great speeches B) The history of the speech C) Functions of the speech D) The language of the speech

Some British and American people like to invite friends for a meal at home. You should not be upset if your English friends don't invite you home. It doesn't mean they don't like you! Dinner parties usually start between 7 p. m. and 8 p. m. and end at about 11 p. m. Ask your host what time you should arrive. It's polite to bring flowers, chocolates or a bottle of wine as a gift. Usually the evening starts with drinks and snacks. Do you want to be extrapolite? Say how much you like the room, or the pictures on the wall. But remember--it's not polite to ask how much things cost. In many families, the husband sits at one end of the table and the wife sits at the other side. They eat with their guests. You'll probably start the meal with soup or something small, then you'll have meat or fish with vegetables, and then dessert, followed by coffee. It's polite to finish everything on your plate and to take more if you want it. Did you enjoy the evening? Call your hosts the next day, or write them a short"Thank you"letter. British and American people like to say"Thank you, thank you, thank you"all the time! You are going to attend a dinner party, and _ . A) you'd better bring a certain present with you B) you must leave home for it at 7 p. m. C) you should ask your host when you should leave D) you must arrive before 8 p. m.
