As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper.

    Procrastination is the thief of time and a lot of students suffer form it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely are doing nothing either.

    Paralyzed (使失去活力) by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell (魔咒).

    According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world's population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don't delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong.

    Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is non sense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones.

    Pelling also points out that procrastination feels particularly delinquent（过失的） in a society that thinks of speedy action as admirable, and, at times, even as a moral good.

    Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is “designed” to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.

    One fine afternoon, I was walking along Fifth Street when I remembered that it was necessary to buy a pair of socks. Why I wished to buy only one pair was unimportant. I turned into the first sock shop that caught my eye. A boy clerk, who could not have been more than seventeen years old came forward. “What can I do for you, sir?” he said. “I wish to buy a pair of socks.” I replied.

    His eyes shone. There was a note of excitement in his voice. “Did you know that you had come into the finest place in the world to buy socks?” I had no idea of that, as my entrance had been accidental. “Come with me,” said the boy, eagerly. I followed him to the back of the shop, and he began to pull down box after box from the shelves, showing their contents（内装物）for my choice.

    “Hold on, lad,” I said, “I am going to buy only one pair!” “I know that,” said he, “but I want you to see how beautiful these are. Aren't they wonderful!” There was on his face an expression of seriousness and pride and delight as if he were showing me the secrets of his religion（宗教信仰）. I became far more interested in him than in the socks. I looked at him in surprise. “My friend,” said I, “if you can keep this up, if this is not merely from having a new job, if you can keep up this high spirit and excitement day after day, in ten years you will own every sock in the United States.”

    Thank you all for coming to the meeting. I'd like to start by confirming (保证) that we will receive some money from the government for our school trip to Indonesia. We will receive about $1,300 per child, which will reduce the whole cost to you.

    Now that we are sure to get the money, it is time to do some serious planning. We are sure that the trip will be very exciting for the children, especially if they have not traveled abroad before. There are many advantages(优点) of having some experiences to different places and cultures. Your children will be able to learn a lot about other people and cultures on this trip.

    Leanne is with us tonight. Leanne, where are you? Put up your hand so that the people can see who you are. Thank you. Leanne went on a trip there with some other students last year and will be happy to tell you of her experiences and answer any questions you might have. We will hear from her a bit later in the meeting.

    We only have five months to organize the trip. From past experience I can tell you that this time will go very quickly. So we need to start organizing the trip.

    This is the agenda (议程) for this evening's meeting:

    Passports: when and how to apply for one.

    Health matters: what precautions (预防措施) you need to take, plus any special needs that your child may have.

    Studying: what kind of the school and type of lessons your child will attend.

    Money: paying for the trip, plus how much money your child should take.

   Hotel: where we will be staying clothing and personal items that your children should take with them.

    A Scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it. Some children reach eagerly for the treat they see. Some last a few minutes before they give in. But others are determined to wait until the last moment.

    By the time the children reach high school, something remarkable has happened. A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular, adventurous, confident and dependable. The children who gave in to temptation early were more likely to be lonely, easily frustrated and inflexible.

    Actually, the ability to delay reward is a sign of emotional intelligence which doesn't show up on an IQ test.

    The hardware of the brain and the software of the mind have long been scientists' concerns. But brain theory can't explain what we wonder about most, like the question why some people remain upbeat in the face of troubles that would sink a less resistant person.

    Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting people's success, brain ability measured by IQ may actually matter less than the qualities of mind once thought of as "character".

    EQ is not the opposite of IQ. What researchers have been trying to understand is how they work together; how one's ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the ingredients for success, researchers now generally agree that IQ accounts for about 20%; the rest depends on everything from social class to luck.

    While many researchers in this relatively new field are glad to see emotional issues finally taken seriously, some few fear EQ invites misuse.

    When many people are worried that there are no more heroes in the modern times, two university students who lost their lives to rescue drowning children have shown that heroes still exist (存在).

    According to the Inner Mongolia Morning Post. the tragedy (悲剧) occurred on the afternoon .December 14,2002 when three school students skating on a frozen lake in Qingcheng Park in Hohhot fell through the ice into the freezing water. More than 20 university students who happened to be near the Spot immediately went to the rescue of the children. Two children were quickly rescued, but the third died. The child's body was not found for three hours. Two of the rescuers, Liu Ye and had Longbiao, also died of cold and exhaustion. The body of Hao who took the lead in jumping into the lake was not found until the next day. A student who was unwilling to tell his name said he and his Classmates from the local college were taking photos at the lake. When they heard the children's criestor help, they went to the ice hole hand in hand to rescue the children. But the ice kept breaking, causing most of them to fall into the icy water.

    Local residents held mourning ceremonies (祭莫仪式) at the lake. Eight of the students were seriously affected by the freezing water and were being kept in hospital for further observation, but their lives were no longer in danger.

The Mona Lisa is the famous Leonardo da Vinci painting of a woman with a mysterious smile. This week, the painting gave up a secret.

Scientists used X-rays to examine the chemical organization of an extremely small part of the more than 500-year-old painting. The researchers discovered a technique Leonardo used in the work. A team in France and Britain discovered an oil paint used for the Mona Lisa was a special, new chemical mixture. It suggests that the Italian artist may have been in an experimental mood when he set to work on the painting early in the 16th century.

"He was someone who loved to experiment, and each of his paintings is completely different technically," said Victor Gonzalez. He is the study's lead writer. "In this case, it's interesting to see that indeed there is a specific technique for the ground layer of the Mona Lisa," he said in an interview with The Associated Press. Specifically, the researchers found a rare compound, plumbonacrite (水蛭石), in Leonardo's first layer of paint. The discovery, Gonzalez said, proved that da Vinci most likely used lead oxide to thicken and help dry his paint.

The scientists looked into its atomic structure using X-rays in a synchrotron (同步加速器). The machine moves particles at close to the speed of light, permitting researchers to look deeper into the paint structure. "Plumbonacrite is really a fingerprint of his recipe," Gonzalez said. "It's the first time we can actually chemically prove it."

Dutch artist Rembrandt may have used a similar mixture when he was painting in the 17th century. Gonzalez and other researchers have found plumbonacrite in his work, too. "It also tells us that those recipes were passed on for centuries," Gonzalez said. "It was a very good recipe."

But the Mona Lisa and additional works by Leonardo still have other secrets to tell. "There are plenty, plenty more things to discover," Gonzalez said. "What we are saying is just a little brick more in the knowledge."
