A strong memory depends on the health and vitality （活力） of your brain. They say that you can't teach an old dog new tricks, but when it comes to the brain, scientists have discovered that this old saying simply isn't true. {#blank#}1{#/blank#}

      Give your brain a workout. Memory, like muscular strength, requires you to “use it or lose it”. The more you work out your brain, the better you'll be able to process and remember information.{#blank#}2{#/blank#}

        Don't skip the physical exercise. While mental exercise is important forbrain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brainstay sharp. It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.

        Get enough sleep. There is a big difference between the amount of sleep you can get by on and the amount you need to function at your best.{#blank#}3{#/blank#}Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys braincells. Studies have also linked stress to memory loss.

        Have a laugh.{#blank#}4{#/blank#} That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specificareas of the brain, laughter engages multiple regions across the whole brain.

{#blank#}5{#/blank#}Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains, “healthy”fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it's not just what you eat—it's also what you don't eat.

A. Eat a brain-boosting diet.

B. Play games with memory.

C. Laughter is the best medicine.

D. But oversleeping is not good for yourbrain.

E. Even skipping a few hours makes adifference!

F. You have to shake things up from timeto time!

G. The human brain has an astonishingability to adapt and change.

    It's a Saturday morning, and I am eager to fly away.My husband and I will meet up with our son on the other side of the country to learn and explore together.Sitting now at the airport gate,my husband wanders away to stretch his legs.Moments later,he returns and whispers in my ear.I rise and follow him around the comer toward a large window facing the landing area.

    On the road, Marines stand straight and the plane door is open.A white hearse(灵车）is parked nearby.A man and a soldier stand on either side of a woman,supporting her and waiting for what is to come.Airport personnel stand in reverent stillness.A few people place their hands over their hearts,as I have done.We're joined in witness,sending respect to an honorable soldier whose name we'll never know.

    The woman looks heartbroken. She cries, knowing she will never hear "Mom”from her son. She'll never feel his tender embrace or enjoy his sweet peck on her cheeks.Another man's face is twisted because of the grief.His son,the tiny boy he no doubt wrestled playfully,the teen he probably taught to drive,and the son he stood so proudly by,now lives only in his memory.

    Those behind the glass stay silent, reflecting on this loss, as the family and soldiers leave.Some of us women, with sorrowful expressions, move slowly away, sharing a mother's profound grief .Soon,each of us will fly off in planes and return to an ordinary life made extraordinary by this soldier's courage，by this family's sacrifice and by this love shared by all that look out of the window.

    People are seeking for opportunities that will assist them in reaching their goals. Marketing yourself can be a good choice, which can help you achieve your goals. Though when people talk about marketing, they usually think that this is about producing a sale, it does not necessarily have to be.

    If you are an employee then you want your boss to take your ideas, and if you are on a job hunting then you want to find a good position. So in reality, marketing really leads to sale. So marketing yourself means you are simply “selling” yourself!

    The common problem in marketing yourself is that most people think that it is unpleasant to market themselves. They think that marketing concerns only to a business. Of course, this is absolutely not true. People who want to attain the success they desire must promote themselves.

    Marketing yourself is a useful tool. The better you market yourself, the more opportunities you will have. Marketing yourself does not really mean telling every person how beautiful and wonderful you are. It means letting your prospective employer know that you exist or you can do something better.

    There are actually several different ways of marketing yourself. But there are only two primary ways that you carry out. The first is to find ways to reach out to others and the second is to construct ways in order for the people to find you and make connection with you.

    To reach out and touch the lives of others, you have to be a good person and a good employee. In that way your good reputation will follow naturally. Have a brief and concise message that you can share with others. When you market yourself, you tell people who you are and what you can do for others. Plan well and practice your message.

    In constructing ways for the people to notice and make connection with you, you must be open to them. Communication is a great opportunity to make an impact especially when you market yourself. You also communicate by what you are wearing. Know the appropriate dress code and have plenty of time to decide what you will wear. Just remember to make a great first impression!

    For many students who desire to move around but not far freely, one of the most common vehicles is the bicycle. For such a seemingly simple invention, its story is not that simple.

    Most historians trace its origin back to 1817, when a German nobleman named Karl von Drais invented a wooden, two­wheeled machine that riders moved forward with their feet. His invention became popular in both England and France, where it eventually became known as the velocipede. Unfortunately, it was eventually banned as a danger to pedestrians and was rarely seen after the early 1820s.

    Things were quiet for several decades until the bicycle development took off in the 1860s. An important milestone happened in Paris in 1863 when pedals were added to the front axle (轴). This occurred in Pierre Michaux's workshop, but it's unclear whether he or his employee, Pierre Lallement, should be given credit for the innovation Lallement moved to the United States, where he obtained a patent for "improvements in velocipedes" in 1866. These new machines proved to be popular, and the name "bicycle" had come into use by 1869. However, many people referred to them as "bone shakers", which described their clunky ride due to a heavy wooden frame and steel wheels.

    In the 1870s, "high wheelers" or "penny­farthings" became popular. However, with a large front wheel and a much smaller rear wheel, they could be dangerous, if riders had to stop suddenly, as they would "take a header" when their momentum (动量) carried them over the front wheel onto their heads. Eventually, English inventor John Kemp Starley designed a "safety bicycle" with two same small wheels, a chain drive, and a set of gears. With tires added in and brake systems bettered in the following decades, bicycle production had skyrocketed to over one million bicycles by 1899.

    Mass production of bicycles increased their popularity greatly, since they became affordable for the average person. Over the course of the 20th century, manufacturers continued to improve the features and design of bicycles as new technologies appeared.
