NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive(再体验)these experiences in nightmares.

    Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase(抹去), the effect of painful memories.

    In November, experts tested a drug on people in the US and France. The drug stops the body releasing(释放)chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.

    The research has caused a great deal of argument. Some think it is a bad idea, while others support it.

    Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.

    "Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor at Harvard Medical School. "This could reduce lot of that suffering."

    But those who are against the research say that changing memories is very dangerous because memories give us our identity(特质). They also help us all avoid the mistakes of the past.

    " All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we want to wipe those memories out," said Rebecca Dresser, a medical expert.

    They had a dozen children, six boys and six girls, in seventeen years. One reason Dad had so many children was that he was confident anything he and Mother teamed upon was sure to be a success.

    Our house at Montclair, New Jersey, was a sort of school for scientific management and the removal of wasted motions — or “motion study,” as Dad and Mother named it.

    Dad took moving pictures of us children washing dishes, so that he could determine how we could reduce our motions and thus hurry through the task. Each child who wanted extra pocket money put forward an offer saying what he would do the job for. The lowest bidder got the contract(合约).

    Dad put process and work charts in the bathrooms. Every child old enough to write — and Dad expected his children to start writing at a young age — was required to sign their names on the charts in the morning after he had brushed his teeth, taken a bath, combed his hair, and made his bed. At night, each child had to weigh himself, mark the figure on a graph, and sign the process charts again after he had done his homework, washed his hands and face, and brushed his teeth. Mother wanted to have a place on the charts for saying prayers, but Dad said as far as he was concerned prayers were voluntary.

    It was strict management, all right. Yes, at home or on the job, Dad was always the efficiency expert. He buttoned his vest from the bottom up, instead of from the top down, because the bottom-to-top process took him only three seconds, while the top-to-bottom took seven. He even used two shaving brushes to make his face smooth enough, because he found that by so doing he could cut seventeen seconds off his shaving time. For a while he tried shaving with two razors, but he finally gave that up.

    “I can save forty-four seconds,” he complained, “but I wasted two minutes this morning putting this bandage on my throat.” It wasn't the injured throat that really bothered him. It was the two minutes.

    What is a lifestyle and how is that different from a life? A lifestyle is about brand names and buying identity or fame. Lifestyle gives a false sense of peace and acceptability that comes from others recognizing what you've bought into (as well as bought). If your car, clothes, and home are expensive, you're sophisticated (世故的) and stylish. If you have the right kind of job or go to the right social gatherings, then you receive the insincere approval of others. This means that your self-esteem (自尊) is always at the mercy of others, with no appreciation of you as an individual.

    A life, on the other hand, is very different. A life is what you lead when you know what matters most to you. It is very simple and comes from being connected to what you know is important and being willing to put that first, no matter what others may think. When you create a life vs. a lifestyle, your self-esteem comes from what's inside you, not what others think about you.

    Lifestyle is expensive financially and personally, because it costs a great deal to keep up appearances and do what you think is socially acceptable. A life is not expensive. Rather than using personal or financial resources, a life generates energy and staying power. It's about liberating yourself from the mindless consumption that society expects. It is about making the choices that are in line with your values, instead of using up your bank account or energy for no heart-driven reason.

    How can you make the change? Understand the difference between a life and a lifestyle. Analyze your current lifestyle to see what is costing you in money, time, stress, and energy to maintain it. Let go and make room for what is really important to you, what supports you and brings you joy. Remember who you are from within, not what you own!

    The New York See It All Tour is exactly what it sounds like: an all-inclusive guided tour of New York City.

    Central Park

    One of the most famous parks in the world, Central Park is a man-made wonder. Not only is it the first public park built in America, but it is also one of the most frequently visited parks, with over 25 million guests per year. Set in the middle of busy Manhattan, its grounds serve as a safe harbor, not only for athletes, and musicians but also for lots of migratory birds each year. One can spend an entire peaceful day wandering its grounds, gazing upon nearly 50 fountains, monuments, and sculptures or admiring its 36 bridges.

    Hudson River Park

    Hudson River Park is a waterside park on the Hudson River that extends from 59th Street south to Battery Park in the New York City district of Manhattan.

    Central Park Zoo

    The Central Park Zoo is a small 6.5-acre zoo located on Central Park in New York City. The zoo began in the 1860s, making it the first official zoo to open in New York. The zoo was improved in 1934, with the addition of many new buildings ranged in a quadrangle around the sea lion pool. Finally, the zoo was repaired in the mid-1980s and reopened in 1988, replacing the old-fashioned cages with naturalistic environments.

It is believed that Chinese knotting, also known as zhongguojie, originated for recording information and exchanging messages {#blank#}1{#/blank#} writing was invented. Over the past thousands of years, knots {#blank#}2{#/blank#} (play) an important part in the life of Chinese. {#blank#}3{#/blank#} (initial), Chinese knots acted as good -luck charms to drive away evil spirits. Today, Chinese knots are widely used to decorate homes during festivities.

A major characteristic of Chinese knots is that they are often tied from a single continuous length of string. The knots are commonly named {#blank#}4{#/blank#} the shape it takes. Chinese knots are created in a {#blank#}5{#/blank#} (various) of colors such as gold, green, blue, or black, though the most commonly used color is red, {#blank#}6{#/blank#} symbolizes good luck and prosperity.

Crafting the Chinese knot is a three-step process {#blank#}7{#/blank#} (involve) tying knots, tightening them and adding the finishing touches. The knots {#blank#}8{#/blank#} (pull) tightly together and are strong enough to be used for binding or wrapping, making them very practical.

Today, most of such knots are often mass manufactured in factories. Skilled knot artists weave complex knots that you might see {#blank#}9{#/blank#} (sell) as souvenirs that you can take back with you. If you have time, why not try your hand at it? Perhaps these age-old charms can add {#blank#}10{#/blank#} touch of good luck to your daily life?
