    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.

    As we all know,drinking beers while running can upset the stomach.However,that's all part of the attraction of the Beer Mile,a unique race that has participants competing in running and drinking.The Beer Mile Race started off as a tradition in 1990,when a group of Canadians thought it would be fun to race each other while drinking a few beers.But it has come a long way since then.The Beer Mile Race is now a major sporting event with around 100,000 official competitors,brand name sponsors and so on.In 2015,the first Beer Mile World Classic was held in San Francisco,where all of the record holders from Canada and the United States came together for the competition.But this year,the event was organized in London,in an effort to take in more competitors about the sport outside North America.

    The rules of the race are pretty simple: runners have to consume four beers before each of the four 400-meter laps making up the famous Beer Mile.The beers can come in bottles or cans but should not be less than 355ml and must be at least 5% alcohol.The drink like apple juice will not do.Runners must drink the beers within a 10 meter zone before the start/finish line and then they are required to tip the bottle/can over their heads to confirm it is empty.

    In the case of vomiting（呕吐）during the race,and yes,there's quite a bit of that during the Beer.Mile,offenders must complete one more lap at the end of the race.Organizers mention that even in the case of vomiting several times, only one more lap must be completed.

    This year,the Elite Men's race was won by Canadian Corey Bellemore,who also set a new world record with a time of 4 minutes and 34 seconds.“I just drink the beers as quickly as I could,hold them down and get the burps（饱嗝）out,”Corey said.“If you can drink a beer in 8 seconds and also run very fast with a feeling of vomiting,then you'll be fine like me.”

    The arts, especially music, should be part of every school's lessons at every grade level. Students would be much smarter if they had musical experience. They could improve their classroom skills, like paying attention and following directions. People develop all these skills when they learn music. Making music also lets children use their imagination. It provides students with a chance to try out their own ideas.

    Music not only makes children better students, but also gives them something positive to do. In a music program, children can be part of a band instead of joining a gang(团伙). Parents can enjoy listening to their children's music instead of seeing them glued to a computer or TV screen. In a school band, students get to be part of a team. They can get along well with old friends and make new friends through music.

    Music builds self-confidence, too. It gives children a sense of achievement and success. Making music is something for them to be proud of. And it lets kids practice performing in front of an audience. Music gives children an opportunity for self-expression, and that helps develop their self-confidence.

    Once again, music is important because it can make children better students, give them something positive to do, and build their character. That is why music should be offered in every single grade in every school.

    By analyzing the fossilized teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants (婴儿) for longer periods than their contemporary relatives.

    The results, published in the journal Science Advances, provide a first insight into the practice of weaning (断奶)that remain otherwise unseen in the fossil record.

    The team sampled minute amounts from nearly 40 fossilized teeth of our South African fossil relatives, early Homo, Paranthropus robustus and Australopithecus africanus. They measured the proportions of their stable calcium isotopes (同位素）in the tooth enamel(牙釉质), which are a function of the mother milk intake by infants. They show that early Homo offspring(后代) was breastfed in significant proportions until the age of around three to four years, which likely played a role in the apparition of traits that are specific to human lineage(血统), such as the brain development.

    In contrast, infants of Paranthropus robustus, that became extinct around one million years ago and were a more robust species in terms of dental anatomy, as well as infants of Australopithecus africanus, stopped drinking sizeable proportions of mother milk in the course of the first months of life.

    These differences in nursing behaviors likely come with major changes in the social structures of groups as well as the time between the birth of one child and the birth of the next.

    One of the study's lead authors, Dr Theo Tacail said: "The practice of weaning -- the duration of breastfeeding, age at non-milk food introduction and the age at cessation of suckling -- differs among the modern members of the hominid family which includes humans and modern great apes: orangutan, gorillas, chimpanzees and bonobos.

    The development of such behavioral differences likely played major roles in the evolution of the members of human lineage, being associated for instance with size and structure of social groups, brain development.

    However, getting insights into these behavioral changes from fossils that are millions of years old is a challenge and, so far, little evidence allow discussing nursing practices in these fossil species.

    The findings stress the need for further exploration of calcium stables isotopes compositions in the fossil record in order to understand the co-evolution of weaning practices with other traits such as brain size or social behaviors."

Let's face it. You're likely reading this article in an effort to avoid some other tasks you're procrastinating (拖延) to learn how to stop procrastination, but the clock is ticking. So why can't you seem to get rid of that?

Though the psychological causes are still debated, there's a human tendency to over or underestimate the value of a reward based on its temporal proximity (时间接近). This is often referred to as temporal discounting. For example, if I offered you $100 today or 110 in a month, most would take the hundred and run. But what if instead I offered you 100 dollars in a year or 110 in a year and one month, you might say to yourself if I can wait a year, I can wait the extra month.

But the time and value difference are the exact same in each example. It turns out that human motivation is highly influenced by how near the reward is meaning. The further away the reward is, the more you discount its value. So being online is more appealing than preparing for your test. The problem is surfing the Internet provides many small quick and continuous rewards unlike your test scores which are a future one.

So how do you overcome the urge to put off so many tasks?

Unfortunately, there is no definite answer, but try rewarding yourself with a timely snack or other enjoyable activities. The Pomodoro Technique makes use of a timer to work for 25 minutes straight and when you've done, this gives yourself the reward with a 5-minute break. Then start the working clock again. Gradually increasing the amount of work time you put in will improve your time management skills.

It's been shown that creating a costly deadline is also an effective way to manage your working habits. And try to enjoy the process of achieving something instead of thinking only our minutes of suffering.
