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.

    Summer is the season to dive into new activities and relax. And right now is the time to make sure that you're ready for the great outdoors, the holiday planning and travel, and the bathing suit beach days.

    If you want to lose weight before summer, concentrate on dropping no more than a pound or two a week.{#blank#}1{#/blank#} And when you trouble yourself, sooner or later you，re going to gain it back. Operate on a 500-calorie-a-day deficit (亏损).{#blank#}2{#/blank#} So if you cut 500 calories a day for seven days straight, you'll lose a pound a week right there.

    Operating at a decrease of 500 calories a day should involve both eating less and moving more. For example, you could consume 300 fewer calories and bum 200 extra per day.

    Include both healthy eating and exercise in your weight-loss plan, and break the 500-calorie goal into small groups to make it more reachable.{#blank#}3{#/blank#}

    To cut 100 calories:{#blank#}4{#/blank#} Have vegetable pizza instead of pepperoni (意大利辣香肠). Use our Nutritional Needs Calculator to determine how many daily calories you should consume in order to lose, gain, or maintain your healthy goal weight. Once you've reached your goal, recalculate your nutritional needs for keeping extra weight off all summer long.

    To burn 100 calories: spend 15 minutes biking. {#blank#}5{#/blank#} Spend 20 minutes gardening. Keep on exercising at least 30 minutes daily a week. Reading food labels and counting calories or writing down what and when you eat can give you more control as well.

A. Here are some simple ways to get there.

B. Walk or run one mile.

C. A pound is 3,500 calories.

D. It is okay to have some snacks between your meals.

E. You should always make sure you get a lot of sleep.

F. Anything more than that usually means you're troubling yourself.

G. Eat a chicken breast without the skin.

Ig Nobel Prize

    Having a meal is an easy and delightful process for most people. However, for a woodpecker (啄木鸟), it's not that simple. To get dinner, a woodpecker has to hit its head against a tree numerous times per day. Yet, amazingly, it never suffers any ill effects like brain damage. According to research, it is the woodpecker's thick head bones that protect it from the impact of the blows. For explaining that, Ivan Schwab won an Ig Nobel Prize.

    Ig Nobel Prizes are organized by The Annals of Improbable Research, an American magazine that celebrates the funny side of science. Each year, ten winners are awarded prizes in honor of their “achievements that first make people laugh, and then make them think”. Most of the award-winning research, like Schwab's, may seem unusual, but it usually grabs people's attention indeed. And no matter how ridiculous the research sounds, people can find it inspiring and amusing.

    Brian Wansink's research might interest you. He took home an Ig Nobel Prize for looking into the influence of visual factors on people's appetites. He used specially designed bowls that refilled themselves with soup while people were eating. Since these people had no idea this was happening, they just kept eating from these “bottomless bowls”. They said they didn't feel full because their bowls were not empty yet. People in this experiment ate 73 percent more soup than normal. Owing to these results, Wansink concluded that it's not people's stomachs that decide when they have eaten enough, but their eyes.

    Ig Nobel Prizes also give attention to science and technology that is a part of our daily lives. Take the karaoke machine for example. Its inventor Daisuke Inoue was employed at a nightclub, playing the piano for the customers who wanted to sing. He wasn't skillful enough to play all the songs properly. To clear up the problem, he created the karaoke machine. To Inoue's surprise, the machine caused considerable changes in entertainment worldwide. The Ig Nobel Prize was awarded to Inoue not only because his invention was entertaining, but also because it brought about “an entirely new way for people to learn to tolerate each other”.

    These research results of Ig Nobel Prizes may not be as great as Edison's light bulb or Newton's laws of motion. However, they do show people's willingness to take action and to try new ways to solve problems. According to Marc Abrahams, a founder of the Ig Nobel Prizes. “If you win one, it means that you have done something.”

    Seventy-three-year-old George McNeilon selected his food in Value Mart very carefully. After leaving the cashier, he estimated (估计) that he had saved 80 cents and thought that he had got good value for his money again.

    At the exit, the chilly wind reminded him of his gloves. "Now where are they?" He searched here and there, but nowhere could he find them. He was sure he was wearing them when he entered the store. The worried man made a second search in all his pockets, again including the grocery bag. He was sure they must have been dropped somewhere inside the store.

    George bought the gloves at a 25% discount, for just $30, ten years ago. They were genuine lambskin (小羊皮), soft, warm and durable. Until then, he had worn cheaper man-made material that lasted no more than three years. His impulsive decision to buy the expensive gloves turned out to be a good one, which even promoted his social status on the bus, as passengers stared at him enviously for six months out of the year. He enjoyed being envied.

    Bad luck, George thought, to lose his expensive gloves on New Year's Eve. He reentered the store and followed the same route he had walked before. But several minutes of anxious search turned out to be in vain. "Society has changed. People have changed …" he murmured to himself. "Years ago, if people picked up something lost, they would give it back."

    Back home, George was at a loss. In deep winter, he could not do anything without a pair of gloves. If he bought cheap ones, he would have to replace them very soon. If he bought new leather ones, they would cost forty dollars.

    After the holiday, poor George decided to buy another pair of leather gloves. Before boarding the subway, he stepped into Value Mart again to see if by any chance his gloves had been returned to the lost and found office.

    "What color are they?" the woman in the office asked.

    "Black," he answered.

    She looked into her drawer and drew out a pair of men's leather gloves.

    "Are they?"

    "Yes! Those are mine!"

    We're often reminded of the importance of preserving the planet as we see it for future generations—and children at St Oswald's Primary School in Chester certainly agree.

    Nine-year-old Isobel Kelleher from the school's Hummingbirds class thinks adults need to take note. “Sometimes they can be busy and I don't think they think they can make a difference，but if everyone does a little bit it all adds up，” she tells HuffPost UK.“ We started looking at plastic pollution in our oceans and the things like plastic bags and broken down pieces of plastic that are polluting them.” she says.“ Fish can eat the plastic and they can die，or we might even eat the fish ourselves.”

    Mr Timms，Isobel's teacher，has been spearheading a new project at the school which lets children loose creatively to raise awareness of the need to be more environmentally friendly. The entire Hummingbirds class，which is made up of 9 and 10-year-old pupils，has been busy writing poems and creating online video adverts to warn adults about the serious situation of our oceans and wildlife.

    Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us. We sometimes overlook how much we can really learn from children.” he says.“ It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic，and to recycle more，and even stopping them using plastic straws.”

    Mr Timms is proud of his Hummingbirds class.“ The message that they would like to send to the world is simple stopping this isn't someone else's job，and it won't be OK if we just leave it.”

    Cli-Fi refers to "climate fiction"; it is a term invented by journalist Dan Bloom. These are fictional books that somehow or someway bring real climate change science to the reader. What is really interesting is that Cli-Fi books often present real science in a believable way. They become fun teaching tools. There are some really well known authors such as Paolo Bacigalupi and Margaret Atwood. A list of other candidate Cli-Fi novels was provided by Sarah Holding in the Guardian.

    What makes a Cli-Fi novel good? In my opinion, it has to have some real science in it. And it has to get the science right. Second, it has to be fun to read. When done correctly, Cli-Fi can connect people to their world; it can help us understand what future climate may be like, or what current climate effects are.

    One thing that is hard to imagine is the future. What will the world be like decades from now when Earth temperatures have continued to rise? What will agriculture be like? What will coastal communities be like? It is also hard to imagine what living a subsistence agriculture life is like, today. What happens to lives and communities when the rains change, or don't come at all? What would that world look like?

    One recent example of Cli-Fi literature is South Pole Station by Ashley Shelby. In this book we follow Cooper Gosling, who is traveling to a research location on Antarctica to create paintings. Yes, an artist is sent to live with researchers and crew ­ with funding from the National Science Foundation. After arriving at the South Pole, Cooper has to become acquainted with the strange social system that exists there. Ashley writes the book in such a way that you actually feel you are huddled(拥挤) in the cold with her and her co-workers.
