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.

    Public Speaking Training

    Get a coach

{#blank#}1{#/blank#} so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that's right for you.

    Focus on positives

Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well. Nothing can hurt confidence more than being told that you aren't doing well.{#blank#}2{#/blank#} so good public speaking training should develop those instead of telling you what you shouldn't do.

    {#blank#}3{#/blank#}

If you find a public speaking course that looks as though it's going to give you lots of dos and don'ts, walk away! Your brain is so full of what you're going to be talking about.{#blank#}4{#/blank#} As far as we're concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.

    You are a special person not a clone (克隆人)

Most importantly, good public speaking training should treat you as a special one, with your own personal habits.{#blank#}5{#/blank#}Your training course should help you bring out your personality, not try to turn you into someone you're not.

A. You aren't like anybody else

B. You already do lots of things well

C. Turn your back on too many rules

D. Check the rules about dos and don'ts

E. Whatever the presentation, public speaking is tough

F. The one thing you don't want is for them to fall asleep

G. So trying to force a whole set of rules into it will just make things worse

    How old is "old"? {#blank#}1{#/blank#} Two hundred years ago, you were old at 35. That was the average life then. At the turn of this century, as medical knowledge advanced, the average life span(长度) increased to 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is looking forward to many more active years.

    So, how old is old? The answer is one you've heard many times, from all sorts of people. "You are as old (or young) as you feel!" The calendar(日历) simply tells you how many years you have lived. {#blank#}2{#/blank#}

    Once an unknown author wrote," {#blank#}3{#/blank#} Nobody grows old by living a number of years; people grow old by giving up their goals."

    {#blank#}4{#/blank#} Alice Brophy, when she was with the New York City commission for the Aging, said, "It upsets me when people say, 'Gee, you look young for your age!' What does that mean? Is there some model that you're supposed to look a certain way at 65 and 75 and 85? You know you can die old at 30 and live young at 80"

    There are many wrong ideas about aging. {#blank#}5{#/blank#} Here are some of the more common ones. For example, most older people are in poor health, or older people are unable to change.

A. It's extremely terrible to be grown old.

B. Youth is not a time of life but it is a state of mind.

C. These ideas stereotype(固化) people on the basis of age.

D. Old is a point of view.

E. Older people are stubborn, unable to change.

F. The answer has changed over the years.

G. Your body tells you how well you've lived.

    Whether you use a GPS device (设备) in your car or Google Maps on your smartphone, few of us travel anymore without digital help. {#blank#}1{#/blank#} For one thing, GPS isn't as accurate as you might think. What's more, science is beginning to discover that people who rely only on navigational technologies may have a poor sense of place during travel.

    {#blank#}2{#/blank#} They soon become outdated as cities change, requiring users to continually purchase updated versions. They're also easily damaged from exposure to water, poor weather conditions and other physical forces.

    However, paper maps still offer a few advantages that technologies can't. For example, studying a map allows you to get a full view of where you're going, including the roads, forests, towns, historic sites, rivers and mountains you'll come across along the way. Many older maps are wonderful, offering a lovely feast for the eyes. {#blank#}3{#/blank#}

    Research by Toru Ishikawa and colleagues at the University of Tokyo found that GPS users spent 30％ more time looking at their device than those who used a paper map. {#blank#}4{#/blank#} Instead they tended to stare at their screens and follow directions, never gaining a full view of where they were going.

    Therefore, go ahead and use your GPS, but also carry a paper map as a handy backup. {#blank#}5{#/blank#} Also it could even be a life-saver!

    To someone stuck in a traffic jam, the ability to fly right over other cars seems like a dream. {#blank#}1{#/blank#} That may be changing. Nearly a dozen companies around the globe are competing to be the first to develop a flying car. One of the ideas being developed is a car with wings that unfold for flight. But, most aren't cars at all. They are more like helicopters and are operated by a battery-powered motor.

    {#blank#}2{#/blank#} Companies have to convince the government that the flying cars are safe. They will also need longer-lasting batteries. And, cities will have to figure out how to handle thousands of flying cars in the sky.

    Still, some companies are moving forward. {#blank#}3{#/blank#} Especially as cities grow more crowded and people spend more time stuck in traffic. These taxis would deliver passengers to the rooftops of office buildings during rush hours.

    "In as little as 10 years, products could be on the market that revolutionize urban travel for millions of people," said Zach Lovering. He is the leader of a project to develop a self-flying taxi for Airbus, a European company that makes airplanes. {#blank#}4{#/blank#} Although Uber doesn't have any plans to develop a flying car itself, the company is advising several companies that are developing them.

    {#blank#}5{#/blank#} Designers think that if enough people want to buy them, prices can be kept affordable.

A. Some flying cars are designed for human pilots.

B. It's still unclear how much flying cars will cost.

C. They see a need for "air taxis" and personally owned flying cars.

D. Companies will also have to get permission from the government.

E. The Uber ride-share company sees air taxis as the future of on-call transportation.

F. Inventors and business people tried to make flying cars, but have never been able to.

G. There are many challenges that could keep flying cars from becoming part of everyday life.

When it comes to having fun in the sun, it's easy to lose track of time. If you're not careful, this can be quite dangerous.{#blank#}1{#/blank#}But it can easily be prevented—all you need is a little sunscreen.

{#blank#}2{#/blank#}People have been using chemical pastes to protect themselves from the sun for centuries. But the first modern sunscreen sold on the market was offered by French company: L'oreal in 1935.

Several other companies were quick to release their own sunscreens. Perhaps the biggest advancement in the world of sunscreen came in the 1970s, when scientists started looking at the sun protection factor, or SPF.{#blank#}3{#/blank#}

The advantages of using sunscreen are obvious. It limits the painful effects of sunburn.{#blank#}4{#/blank#}Millions of people have died from skin cancer caused by ultraviolet rays from the SUITL. Remember to apply sunscreen 30 minutes before going outside.

Unfortunately, there are many mistaken ideas about sunscreen.{#blank#}5{#/blank#}Some also think you only need to put it on once for a whole day's protection or that you don't need it on cloudy days. None of these things are true. Experts say you should apply sunscreen every two hours when outside in the daytime, no matter how dark your skin is or what the weather is like.

A. And it can even save your life.

B. Sunscreen is not exactly a recent invention.

C. Choosing a sunscreen isn't as simple as it used to be.

D. In direct sunlight, sunburn can occur in less than 15 minutes.

E. This rating is a number that shows how effective a sunscreen is.

F. It's believed that you don't need much sunscreen if you have dark skin.

G. Some think a good method is to cover as much as possible with protective clothing.
