Winter running is the best way to lose winter weight. But before heading out, make sure you have a solid plan. You don't want to come across accident along the way. {#blank#}1{#/blank#}

    Wear the Right Shoes

    The right shoes will depend on the road. You want shoes that are made for the kind of surface you run on. For example, if you are running on slippery surfaces, you want shoes with great friction(摩擦力). {#blank#}2{#/blank#} When trying out a pair of running shoes, check the fit, feel and ride of the shoes. These elements(要素) are important once you take your new shoes out for a run.

    Warm Up

    Warm up is an important part to keep fit. Especially if temperatures drop and your muscles are stiff(僵硬的) from the cold! {#blank#}3{#/blank#} It also prepares the muscles for the intense (激烈的) activity ahead. The cold climate won't feel as cold when you do warm ups. This is because blood flows much faster after a good warm up!

    Deal with Wind

    {#blank#}4{#/blank#}The key is to run into the wind and finish by running against it. This keeps icy wind from blasting(用力撞击) your face. To prevent any injuries or accidents, break your run into small parts. {#blank#}5{#/blank#} You can use certain creams on the nose and cheeks to prevent frostbite(冻疮).Don't skip your sun-block if you're running during the day. UVB(紫外线)passes through the clouds. Running for an extended period on a cloudy day will still damage the skin!

A．Don't run in the wind.

B．Running makes you warm.

C．Warming up prevents injuries.

D．It's hard to run if it's too windy.

E．Your shoes should fit very well so you don't slip.

F．Here we are giving you important tips to remember.

G．It also helps to keep the skin protected from the wind.

    Truman headed home from school, with the homework in mind, a report on beehives (蜂巢). Truman's class had studied bees for three days, so he was ready. But, as his teacher Mrs. Lawrence had explained, to earn an A +，he needed a “new angle”.

    Truman pushed open the front door to find his four-year-old brother, Bryan, sitting on the living room rag, hard at work. Paper towel tubes were all over the floor.

    Bryan quickly stood up. “Truman, help me build a city!”

    “I'd like to,” Truman replied, “but I have to do a report on beehives and ...”

    “Can I help you?” Bryan begged.

    “I don't think so, Bry. Sorry.''

    “I know where there's a beehive.” Bryan smiled.

    “Where?”

    “In the wood pile by the garage.''

    The boys marched to the firewood. Bending down, Bryan pointed out the hive deep inside the pile. Truman carefully removed the hive out.

    “You got it!” Bryan shouted.

    Back in the living room, Truman paced around, turning the fragile hive under his nose. Each cell was a perfect hexagon(六边形). How did the bees fit the cells together so neatly? And how did they make each cell six-sided? Could they count? Lost in thought, his foot came down on something ...

    “Truman! You're mining my city!”

    “Get your stupid tubes out of here，Bryan! I'm trying to…”

    The towel tubes on the floor suddenly reminded him of something. The beehive!

    Looking closer, he noticed the tubes were arranged with one in the middle, surrounded by six others, just like the cells of the hive.

    Just to be sure, he tried five and then seven tubes surrounding the center tubes, but neither way fit. Six was the only number that worked.

    “Bees don't count to six,” he said aloud. “The cells have to be six-sided.

    Truman ran to Bryan and threw his arms around his brother. Bryan, you did it! Now I can build a model beehive with your tubes! I mean — if it's O. K. with you.”

    Do you believe in the power of music? If you're like most kids these days, you probably have an electronic device loaded with hundreds or even thousands of your favorite songs. At any moment in time, you can fill your headphones with the sounds of a particular song that suits your mood at that exact time.

    Are you getting ready for a big soccer match or do you need to get excited? Maybe some hip hop with a strong beat will do the trick! Besides, you might be ready to study for a big exam the next day. To calm your nerves and help you concentrate, a little bit of Mozart might make memorization more manageable.

    But is there any scientific evidence of these effects that music seems to have? You bet there is! Scientists have long recognized the power of music. Over the years, many studies have been conducted to examine in greater depth the nature and extent of the effects music has on people.

    For example, scientists at the University of Missouri have found that listening to music can have a positive effect on your mood. Their research gives scientific credibility(可信性) to the behavior that many people have already experienced on their own: listening to upbeat music can brighten your day and boost your mood.

    Other studies have shown that upbeat music isn't the only type of music that can be helpful, however. When people are sad or have suffered a personal loss, sad music can be helpful because people identify with the tone and lyrias(歌词) of the music. Likewise, people under a lot of stress or experiencing upsetting situations can benefit from listening to angry music. Although angry music might not help you if you're in a normal mood, its tone can benefit you when you are dealing with stressful and upsetting situations.

    Boomerang children who return to live with their parents after university can be good for families, leading to closer, more supportive relationships and increased contact between the generations, a study has found.

    The findings disagree with the research published earlier this year showing that returning adult children trigger a significant worsening in their parents' quality of life and wellbeing.

    The young adults taking part in the study were "more positive than might have been expected" about moving back home – the shame is reduced as so many of their friends are in the same position, and they acknowledged the benefits of their parents' financial and emotional support. Daughters were happier than sons, often getting back easily to teenage patterns of behavior, the study found.

    Parents on the whole were more uncertain, expressing concern about how they can arrange and manage it if their children continue to live with them. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.

    The families participated in the study were middle-class and were more likely to view the achievement of adult independence for their children as a "family project". Parents accepted that their children needed support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out or even afford their own house.

    "However," the study says, "many parents and a little over half the graduates report day-to-day tensions (矛盾) about the prospects of achieving adult independence, which in a few extreme situations came close to conflict".

    Areas of disagreement included housework, money and social life. While parents were willing to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.

    You've got your fancy new suitcase and you're ready to take it with you on your travels across the globe.

    You get to the airport, quickly moving through the crowds on the uneven pavement, rushing to check in. Then, your heart sinks when you realize your new suitcase has got a serious case of the wobbles (摇晃).

    Why does this happen?

    Scientists from the Universite Paris-Diderot in France investigated this matter and published their findings in the science journal Proceedings of the Royal Society A. They also suggested some solutions to overcome this modern-day problem.

    To learn more about the issue, they put a suitcase on a treadmill (跑步机) and observed what happened.

    It was soon noted that the "wobble" was actually a result of repeated actions that caused the suitcase to sway from side to side. They discovered that if one of the wheels encountered an obstacle such as a small bump, it jumped into the air for just a moment and then banged back down to the ground. That second action caused the opposite wheel to lift off the ground and then to bang back down, causing the first to lift again and so on. This swaying increased as the luggage was pulled along.

    "The suitcase is a fun way to tackle the problem, but the study would be the same for any trolley with two wheels or blades (桨叶)," Sylvain Courrech du Pont, lead author of the study, told BBC News. "So it will be the same for a caravan (大篷车) or maybe also for airplanes."

    Instead of slowing down when we see a rocky part of the path, the scientists recommended doing the exact opposite and speeding up. This is because going faster gives the wheels less time to rise and fall, preventing the case from swaying. They also said that reducing the angle of the suitcase by lowering its handle to the ground would help keep it steady.

    "These findings could help researchers simulate and design better rolling suitcases and other pulled trolleys, such as towed trailers," Courrech du Pont added.

With these masterminds (智者) working on perfecting our suitcase problems, wobbly luggage may soon be a thing of history, leaving us to enjoy our travels.
