“Body clocks” are biological methods of controlling body activities. Every living thing has one. In humans, a body clock controls normal periods of sleeping and waking. It controls the times when you are most likely to feel pain. Eating, sleeping and exercising at about the same time each day will help keep body activities normal. But changes in your life—a new job, for example—destroy the balance and thus cause health problems. You could have difficult sleeping, for example. Scientists suggest that early afternoon is the best time of day for physical exercise. They say we are stronger and faster then. Later, about four o'clock, most people feel tired because of the drop of sugar level in the blood. Early afternoon also is a good time to do tasks about memory（记忆） and mathematics. If you must study, however, do it just before going to sleep at night. Scientists say you are more likely to remember information when there is a short delay（耽搁）between study and bed. Body clocks control all the activities from day to day. They also produce changes about every ninety minutes during the day. At the end of such a time period, our ability to think hard begins to become weak. That is the time we are most likely to day-dream. Within fifteen minutes, we are ready to go back to what we were doing.

    Football, to me, is more than just a game. I have probably learned more valuable lessons from it than from school.

    When I joined the team freshman year, I didn't realize what I was getting into. Even though I had been playing since fourth grade and knew it was hard work, nothing would prepare me for the effort I would put into football that year. We worked all summer in the weight room and ran on the track to get in physical and mental shape before the season.

    See, football is more of a mental sport than anything else, so running on the track wasn't only about getting in shape, we would push our minds by running as hard as we could even if we were going to pass out. At the beginning, I was immature（幼稚）and only thought of myself, sometimes even gave up when I was tired or hurt. Then after the third game I had a season-ending injury. Imagine working all summer and then only being able to play three games! I needed surgery（外科手术）on my arm and at least five months to recover.

    Needless to say, I missed the rest of the season, but this actually helped me realize that since you never know when your last play will be, you should try your hardest in football and life.

    After freshman year I decided that I would always give my best effort. Playing varsity（校队的）football has taught me so much more than just what my assignments are on a particular play or how to block. I have learned to think about others first and realized how important working hard is. Being with all my friends, even sweating and bleeding with them, really made us bond as a group of hard-working young men who I know will succeed in life.

    Looking almost as fresh as the day it was bought, this McDonald's Happy Meal is in fact six months old. Photographed every day for the past six months by Manhattan artist Sally Davies, the kids meal of fries and burger hasn't any signs of mould(霉菌) or decay(腐烂).

    Sally put the Happy Meal on a shelf in her apartment and watched it with increasing shock. Even her dogs stopped trying to steal a free tasty snack.

    “I bought the meal on April 10 this year and brought home to see how it changed,” she said. “I chose McDonald's because it was nearest to my house, but the project could have been about any other fast food. The first thing that shocked me on the second day of the experiment was that it no longer gave out any smell. And my dogs stopped circling the shelf.”

    Sally expected the food to go mouldy after a few days. In fact, Mrs. Davies' surprise turned to shock as the food still had not shown any signs of decay after two weeks. “It was then that I realized that something strange might be going on with this food that I had bought,” she explained. “The appearance of the food did not change as the weeks turned to months. And now, at six months old, the food is plastic to touch. The only change that I can see is that it has become as hard as a rock.”

    The experiment has brought her amusement rather than fear. “Maybe I would be frightened at seeing this if I were a meat eater.” she said.

    Children who often move house are more likely to suffer poor health, research suggests. Moving several times before the age of 18 can affect the health, psychological distress and increase the chance that a child may use illegal drugs.

    The study included information for 850 people, followed-up for a period of 20 years. Scientists found changing home several times could cause psychological distress in children.

    By the age of 18, 59 percent had moved house once or twice while one in five had moved at least three times. Some 20 percent had stayed in the same house during their childhood.

    Children of single parents or those with step-parents were more likely to move home, as were those with two or three brothers or sisters. Those with four or more brothers and sisters were more likely to stay in the same house.

    Experts found that people who moved at least once had an increased risk of poor health, some of this could be because of changing schools. Those who had moved three times or more were three times as likely to have had suicidal thoughts as those who stayed in the same house.

    Dr Denise Brown said, “For many people, moving house is a good experience as it may lead to improved family conditions. But for some family members, especially children, moving can be bad and may lead to poor health outcomes and behaviors in adulthood. The bad effect on health in adulthood appears to be somewhat accounted for by a high number of school moves.”

    In 1812, the year Charles Dickens was born, there were 66 novels published in Britain. People had been writing novels for a century—most experts date the first novel to Robinson Crusoe in 1719—but nobody wanted to do it professionally. The steam-powered printing press was still in its early stages; the literacy（识字） rate in England was under 50%. Many works of fiction appeared without the names of the authors, often with something like “By a lady.”Novels, for the most part, were looked upon as silly, immoral, or just plain bad.

    In 1870, when Dickens died, the world mourned him as its first professional writer and publisher, famous and beloved, who had led an explosion in both the publication of novels and their readership and whose characters — from Oliver Twist to Tiny Tim— were held up as moral touchstones. Today Dickens' greatness is unchallenged. Removing him from the pantheon（名人堂） of English literature would make about as much sense as the Louvre selling off the Mona Lisa.

    How did Dickens get to the top? For all the feelings readers attach to stories, literature is a numbers game, and the test of time is extremely difficult to pass. Some 60,000 novels were published during the Victorian age, from 1837 to1901; today a casual reader might be able to name a half-dozen of them. It's partly true that Dickens' style of writing attracted audiences from all walks of life. It's partly that his writings rode a wave of social, political and scientific progress. But it's also that he rewrote the culture of literature and put himself at the center. No one will ever know what mix of talent, ambition, energy and luck made Dickens such a singular writer. But as the 200th anniversary of his birth approaches, it is possible — and important for our own culture—to understand how he made himself a lasting one.
