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.

    Researchers continue to show the power behind our sense of smell. Recent studies have found, among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers on roads.

    The review explains that smell is unique in its effects on the brain. According to Conrad King, the researcher who carried out the review, “more than any other senses, the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings. This is why the smell of baking bread can destroy the best intentions of a dieter.”

    Smell, which dictates(决定) the unbelievable complexity of food tastes, has always been the least understood of our senses. Our noses are able to detect up to 10,000 distinct smells. Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000 genes (基因), which make up an amazing 3% of the human genome. Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004 for their ground-breaking research on the nature of this extraordinary sense. These two scientists were the first to describe the family of 1,000 olfactory (嗅觉) genes and to explain how our olfactory system works.

    According to one study in the research review, smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users. They are then more likely to speed and experience uncontrollable anger on roads. The most reasonable explanation is that these can all make drivers feel hungry, and therefore desperate to satisfy their appetites.

    In contrast, the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers' impatience. Similarly, the smells of lemon and coffee appeared to promote clear thinking and mental focus.

    However, the way genes regulate smell differs from person to person. A study by researchers in Israel has identified at least 50 olfactory genes which are switched on in some people and not in others. They believe this may explain why some of us love some smells and tastes while others hate them. The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors.

    A new discovery may change how scientists think about prehistoric humans. Human history is more of a war movie than a romantic comedy, at least as far as other animals are concerned; we may be causing one of the planet's great extinction events at the moment. But a recent discovery means humans might not be as destructive as we thought.

    Large animals have a history of disappearing when humans move to their areas. Scientists have long believed that humans simply hunted big animals because people are really good at hunting. For example, scientists thought humans arrived in Madagascar around 4,000 years ago, but only two thousand years later, giant lemurs, giant tortoises and elephant birds disappeared from the island. Many scientists thought humans had something to do with that rapid drop in biodiversity(生物多样性).

    At least, that's what scientists thought until a group of researchers dug up a lot of bones in Madagascar recently. These bones belonged to the elephant bird, a kind of extinct bird that weighed up to 1,000 pounds. The huge bones were covered in cuts that clearly came from a human hunter. The researchers found that the humans had killed the birds 10,000 years ago...Thousands of years before scientists believed humans had come to the island.

    "Our research provides evidence of human activity in Madagascar more than 6,000 years earlier than suspected, which shows that a different extinction theory is required to understand the huge biodiversity loss that has happened on the island." explained James Hansford, one of the researchers. "Humans seem to have coexisted with elephant birds and other now-extinct species for over 8,000 years, clearly with limited negative influence on biodiversity for most of this period."

    If humans lived among large animals for thousands of years without wiping them out, then maybe our species can't wipe other species out. Rather, extinction is more of a habit we've learned. Perhaps we can unlearn it too.

    Many high school students consider a college education useless. Therefore, they choose not to go to college. If you're one of them, think again. Here are some reasons why you should go to college and receive a good education there.

    Schools and universities are the first sources of knowledge. We take that knowledge later on to build our careers after graduation. More knowledge will be gained after you start working, but without an education, that job will not be within easy reach. Knowledge leads to knowledge.

    While limited within the walls of the educational institutions, we openly explore other cultures of the world. We come to know that ours is not the only culture. Other cultures have valuable insights to share, enriching our own Education also makes us want to travel and interact with various cultures, broadening our horizons.

    When there's a downturn in the economy, those who attended college will be more likely to find a new job than those who only finished grade school and have a limited skills set. The more education you have, the more chances you will get to improve the quality of your life as you have a better job and earn a higher salary.

    When you're skillful and knowledgeable, you get to "rub knees" with people of similar backgrounds and tastes. It means a good education leads to excellent networking. Good networking can benefit you a lot in your later life.

    A good education makes you a more interesting person. You can talk about ideas and events instead of just other people and what's on sale in stores. An educated person doesn't gossip, having a preference to discuss ideas and listen to what other people have to say.
