It's 10:00 on a beautiful Sunday morning in California. To my left is some of the most beautiful coastline. I'm walking along a road ordinarily packed with cars on days like this, but today, thanks in part to my $135 entry fee, it is closed to traffic.

    There's only one problem: I should be running, not walking. Over the past year, I've spent hundreds of dollars on running gear(设备) and race entry fees. I've jogged than 1,600 miles training for this event.

    Dozens of runners pass me on either side, each of them experiencing varying degrees of sadness similar to my own. Most of them, like me, have traveled hundreds of thousands of miles to get here, spending $500, $1,000 or more to participate in this event.

    Actually I'm by no means a competitive athlete. My best finish ever was fourth place, in a 5-kftometer race with only 74 participants, many of whom were walking the entire course.

    Last year, over 500,000 runners completed a marathon in the U.S. alone. Nearly all of these runners had absolutely no chance of victory. The PR-personal record-is everyone's definition of a “good race,” whether he finishes in first or 301st.

    I should buy a new watch that not only tracks my location by GPS, but also by counting steps. This can more accurate and much more expensive. Finally, I have reached the finish line. I know that the official race photographers will be taking photos as I cross the line, so I raise my arms in “victory” I finish, in a time of 3:37:55, good for 354th place.

    A few days after the race, the race organizers email me a link to a site where I can preview my official photos 一 and download them, for a fee, of course.

    I wish I could say the feeling was unique; it's probably not Indeed probably a feeling most runners get in most marathons. Running a lot of marathons 9 in fact, may not even be good for your health.

    In America, marathoning is a rich person's sport.

    People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can't focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.

    Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants' multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.

    Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.

     “People multitask not because it's going to lead to greater productivity, but because they're distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.

    Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn't find out whether people who start out less focused tend toward multitasking or whether people's recognizing and understanding abilities change as a result of multitasking.

    The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they're dangerous.”

    It is natural that young people are often uncomfortable when they are with their parents. They say that their parents don't understand them. They often think that their parents are out of touch with modern ways, that they are too serious and too strict with their children, and that they seldom give their children a free hand.

    It is true that parents often find it difficult to win their children's trust and they tend(倾向) to forget how they themselves felt when young.

    For example, young people like to act on the spot without much thinking. It is one of their ways to show that they have grown up and they can face any difficult situation. Old people worry more easily. Most of them plan things in advance, at least in the back of their minds, and do not like their plans to be upset by something unexpected.

    When you want your parents to let you do something, you will have better success if you ask before you really start doing it.

    Young people often make their parents angry with their choices in clothes, in entertainment and in music. But they do not mean to cause any trouble; it is just that they feel cut off from the older people's world, into which they have not yet been accepted. That's why young people want to make a new culture of their own, and if their parents don't like their music or entertainment or clothes or their way of speech, this will make the young people extremely happy.

    Sometimes you are so proud of yourself that you do not want your parents to say “yes” to what you do. All you want is to be left alone and do what you like. It is natural enough, after being a child for so many years, when you were completely under your parents' control.

    If you prefer to control your life, you'd better win your parents over and try to get them to understand you. If your parents see that you have a high sense of responsibility, they will certainly give you the right to do what you want to do.

    Reading is the ability to process text, understand its meaning and to integrate it with what the reader already knows. Of all the reading skills speed-reading is a necessary skill in the Internet age. We skim over articles, e-mails and WeChat to try to grasp key words and the essential meaning of a certain text. Surrounded with information from our electronic devices, it would be impossible to cope if we read word by word, line by line. But a new trend calls on people to unplug and enjoy reading slowly, listing benefits beyond the intelligent stimulation.

    A recent story from The Wall Street Journal reported on a book club in Wellington, New Zealand, where members meet in a cafe and turn off their smartphones. They sink into cozy chairs and read in silence for an hour. Unlike tradition book club, the point of the slow reading club isn't exchanging ideas about a certain book, but to get away from electronic devices and read in a quiet, relaxed environment. According to The Wall Street Journal, the Wellington book club is just one example of a movement started by book lovers who miss the old-fashioned way of reading before the Internet and smartphones.

    Slow readers, such as The Atlantic's Maura Kelly, say a regular reading habit sharpens the mind, improves concentration, reduces stress levels and deepens the ability to sympathize. Another study published last year in Science showed that reading novels helps people understand others' mental states and beliefs, a fundamental skill in building relationships.

    Yet technology has made us less attentive readers. Screens have changed our reading patterns from the top-to-right, left-to-right sequence to a wild skimming and skipping pattern as we hunt for important words and information. Reading text punctuated with links leads to weaker comprehension than reading plain text. The Internet may have made us stupider, says Patrick Kingsley from The Guardian. Because of the Internet, he says, we have become very good at collecting a wide range of interesting news, but we are also gradually forgetting how to sit back, reflect, and relate all these facts to each other.

    Slow reading means a return to an uninterrupted, straight pattern, in a quiet environment free of distractions. "Aim for 30 minutes a day," advises Kelly from The Atlantic. "You can squeeze in that half hour pretty easily if only during your free moments, you pick up a meaningful work of literature," Kelly said. "Reach for your e-reader, if you like. Kindles make books like War and Peace less heavy, not less substantive, and also ensure you'll never lose your place."

    The effects of coffee consumption on health have long been a subject of conflict and uncertainty. Since the 1980s, some have spoken out against coffee as harmful to health, while others have welcomed coffee for its supposed benefits to health.

    According to a scientific report, mild coffee consumption, three to five cups per day, can be taken as a healthy dietary pattern, along with other healthful behaviors. The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson's disease.

    According to Dr. Donald Hensrud of Mayo Clinic, high consumption of coffee has health risks. Dr. Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body. Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.

    According to conclusions from a recent study led by Dr. Gregory Marcus, a doctor from the University of California San Francisco, daily moderate consumption of caffeine, less than 4 cups, is not associated with these issues.

    Until the scientific community reaches a general agreement on the effects of coffee consumption on human health, it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.

    When informed of these possible health benefits and harms of drinking coffee, Harwood, a high school student stated, "Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake."

    Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently I walked into the locker room of a rather well­known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half­dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough, each one of these men had been a man of affairs and wealth, successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, else­there would not have been the constant effort to escape the realities of life through scotch and soda. They knew, each one of them, that their productivity had ceased (停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.

    What is the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible. The words were few, but they became memorably impressed on my mind. "In the sweat of the face shall you eat the bread."

    To me, that has been a challenge from my earliest recollections (memories). In fact, the battle of life, of existence, is a challenge to everyone. The immortal words of St. Paul, too, have been and always will be a great inspiration to me. At the end of the road I want to be able to feel that I have fought a good fight, I have finished the course, I have kept the faith.
