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. Question: When you sleep 7.7 hours a night,you will _ .

Most of the "tricks" they're taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins' mothers always provide their young children with guidance and possibly, love. Great apes The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans' that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships. Elephants Everyone has heard the phrase "an elephant never forgets". Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad. Parrots As proved by this list, parrots are very smart. They are also the only animals listed that can actually hold a conversation. Some parrots know hundreds of words by imitating humans. The birds are also capable of remembering words and using them intelligently in response to situations. Question: Which kind of animal has a long-term memory? Options: A: Dolphins. B: Great apes. C: Elephants. D: Parrots.

Q: Read the article and select the best answer. Article: 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. Question: What would be the best title for the passage? Options: A: Tips of great speeches B: The history of the speech C: Functions of the speech D: The language of the speech
A: C
