    Weighing too much can damage your health, and obesity is a growing problem for both kids and adults around the world. Sleep might be one answer to the problem. A new study has found that elementary school students who slept too little were more likely to gain pounds.

    Past studies have shown a link between sleeping less and weighing more, but scientists have had a tough time determining "which came first, the chicken or the egg," says Julie C. Lumeng of the university of Michigan in Ann Arbor. In other words, it hasn't been clear whether kids who weigh too much have trouble sleeping, or whether sleeping less leads to weight gain. Both scenarios (可能出现的情况) seemed equally possible.

    To get a better idea of which causes which, Lumeng and her colleagues interviewed the parents of 785 third graders from around the United States. The parents answered questions about how well their kids slept that year. Three years later, the parents answered the same questions. By sixth grade, 18percent of kids involved in the study were obese.

    The scientists found no relationship between weight and the students' race or gender. It also didn't matter how strict their parents were, or whether they were boys or girls. Obesity struck all of these groups equally. Instead, sleep seemed to be the key factor. Over the three years of study, the children averaged a healthy 9. 5 hours of sleep a night. Some kids, however, slept a lot more or less than others.

    For the sixth graders, every hour of sleep above the 9. 5houraverage was linked to a 20 percent lower risk of being obese. Sleep appeared doubly important for the third graders. Every extra hour of sleep they got was linked to a 40 percent drop in obesity.

(1)、What does the underlined sentence on paragraph 2 imply?
A、Scientists have found the exact causes of children's obesity. B、There is always something difficult to understand through theory C、The cause–effect relationship between weight and sleep isn't clear. D、A person's weight has something to do with the amount of his sleep.
(2)、What did the interview find out?
A、9.5 hours of sleep a night is enough for children. B、The more a child sleeps, the healthier he will be. C、Sixth graders need much more sleep than third graders. D、One's race or gender has nothing to do with his weight.
(3)、How does the author develop the passage?
A、By listing figures B、By comparing different opinions C、By providing examples D、By conducting a survey
(4)、What is the suitable title for the passage?
A、The benefits of enough sleep for children B、Sleeping less increases the risk of obesity C、Which comes first, little sleep or obesity D、How many hours of sleep do children need?

    Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone­faced teacher. Having no choice, I slowly raised the report I had read carefully, hoping to hide myself. “What could be causing everyone to act this way?”

    Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice: flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails,my report would be about the great man who invented peanut butter, George Washington Carver.

    Weeks later, standing before this unfriendly class, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear,“My report is on George Washington, the man who started the American Revolution.” The whole world became quiet! How could I know that she meant that George Washington?

    Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re­dos; no new grade. I felt that the punishment was not fair, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster's office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my opinion to skip the sixth grade. Justice is sweet!

    Many people traveled to Las Vegas, Nevada last week for the 50th Consumer Electronics Show, or CES. The show is said to have the largest collection of new electronic devices in the world.

    The show had many examples of “smart home” devices. “Smart home” technology is designed to make life easier for people by letting computers control many things inside our homes. One such device actually begins working outside the home, when someone arrives and rings the doorbell.

    “When someone comes to your front door and rings the doorbell, the light can turn on immediately. I get a notification when I'm halfway around the world that someone came, and I can start talking to the person who's at my front door, and I can say, 'Oh, here let me let you in,' I can unlock the door for them very easily.” Said Vivint, a smart home service provider.

    One electronics maker launched a device that lets people see and interact with their animals when they are away. The device, from Petcube, lets you remotely watch and talk to your pet through a personal device, according to a company official. It can even give the pet a treat—if you approve and order it.

    For heating or cooling, there is a smart thermostat. This device can also send you a message if a big storm causes leaks of flooding. “We're trying to catch it with just a few drips before it becomes a real big problem,” said Mike Sale of iDevices.

    A concern for many homeowners is the possibility that someone else might find a way to attack these smart home devices. An official from Vivint said his company is sure that only owners of the home can gain use of information on the devices. Warren Katz from iDevices said his company employs engineers from the defense industry to help prevent hacking.

    Some people dream about becoming engineers. Luckily, the new IMAX film Dream Big shows how engineering can improve people's lives. It teaches viewers how engineers use high-tech to help the world. The film hits IMAX theaters nationwide on February 17 to celebrate Engineers Week.

    The film, taking place in locations like China, Dubai and Africa, tells the stories of engineers who try to come up with creative ideas to save energy and help people.

    Dream Big was directed by Greg MacGillivray who has 38 films under his belt, including some of the most successful films ever shown in IMAX theaters.

    How did MacGillivray get into the moviemaking business? “I grew up at the beach. My first movies were about surfing and the ocean. As time went on, I saw the changes in the ocean including polluting and overfishing. So I started making films about conservation of nature.” He told TFK. Now, his films cover a variety of topics, from the natural world to human creation.

    One of the engineers in Dream Big is Angelica Hernandez. In high school, she was on a team that best MIT, a university, in an underwater robotics competition. Today, the engineering work she does focuses on helping people use less energy and save money and resources. “I work with companies to promote energy efficiency with their commercial customers, so it's really trying to push forward all the measures that customers and high-energy users can apply, she explains.

    Engineering is such a good job-you make good money, travel around the world, solve amazing problems and help people.” She says.

    The mission of Dream Big is to show people the good that engineers can do to the world. “That was the impulse of making this movie”, MacGillivray explains, “We want to explain engineering in a way that will get the kids very excited about it.” “Whoever and wherever you are, you can become an engineer,” he adds, “All you need is the creative spirit.”

    Kong Zi, also called Confucius (551B.C-479B.C, and Socrates (苏格拉底) (469B.C-399B.C) lived only a hundred years apart, and during their lifetimes there was no contact between China and Greece, but it is interesting to look at how the world that each of these great philosophers came from shaped their ideas, and how these ideas in turn, shaped their societies.

    Neither philosopher lived in times of peace, though there were more wars in Greece than in China. The Chinese states were very large and feudal (封建的), while the Greek city-states were small and urban. The urban environment in which Socrates lived allowed him to be more radical (激进的) than Confucius. Unlike Confucius, Socrates was not asked by rules how to govern effectively. Thus, Socrates was able to be more idealistic, focusing on issues like freedom, and knowledge for its own sake. Confucius, on the other hand, advised those in government service, and many of his students went out to government service.

    Confucius suggested the Golden Rule as a principle for the conduct of life: "Do not do to others what you would not want others to do to you." He assumed that all men were equal at birth, though some had more potential than others, and that it was knowledge that set men apart. Socrates focused on the individual, and thought that the greatest purpose of man was to seek wisdom. Like Confucius, he believed that the superior class should rule the inferior (下层的) classes.

    For Socrates, the family was of no importance, and the community of little importance. For Confucius, however, the family was the center of the society, with family relations considered much more important than political relations.

    Both men are respected much more today than they were in their lifetimes.
