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.

    “I like photography because it captures amazing things that you might not see again,” Timmy Walsh says. He takes pictures of flowers, sunsets and road signs. But those photos don't usually end up in a scrapbook(剪贴簿) or on his bedroom walls.

    When Timmy was five, he found out that his aunt Bev had lung cancer. He wanted to do something to help her. His first idea was to sell his photos from a lemonade--type stand in front of his house in Pennsylvania. “My mom said it wouldn't work because we were not on a busy street,” Timmy explains.

    His next idea was to have an art show. Timmy decorated his home with candles, flowers, and white lights. Then he arranged his photos. Timmy's mom, Sheila, remembers: “Our dining-room table was filled, the living room—everything was filled with photos.” Friends, family, and Timmy's teachers came to the show. He raised more than $300 for cancer research that night. Aunt Bev was “very happy and excited,” he says.

    After a local newspaper wrote a story about Timmy's photos, a volunteer offered to help him set up a website. As people learned about his cause, called Camera for a Cure, Timmy began receiving invitations to sell his pictures at art galleries and fund-raisers. Since then, his work has appeared in more than 20 shows.

    When Timmy is at a show, he greets each customer and talks about what he was thinking when he took his photos. And he always shares facts about lung cancer. Sometimes donations and sales are slow, but that doesn't bother him. “It doesn't matter how much money we made because we just raised awareness,” he says. Timmy knows that finding a cure for lung cancer will take time and effort. So Timmy will keep doing his part by shooting and selling photos of the things he sees.

    The wonderful experiment I am going to introduce proves that air is just all around and that it presses down upon us. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth's surface.

    The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment！

    What you need:

·A hard-boiled egg without the shell

·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Method:

1） Check that the paper will sit firmly on the neck of the bottle.

2） Tear the paper into strips and put the strips into the bottle.

3） Light the paper by dropping a burning match into the bottle.

4）Quickly sit the egg on the neck of the bottle.

Result:

    Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

    Why it happened

    As the paper burns, it needs oxygen and uses up the oxygen（air）in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on it.

    Walk down any British shopping street and you will find shops with strange names. Why is the opticians (眼镜店) called "Eyediology"? And who decided to name the butchers (肉铺) "Meat you there" ? What's going on?

    Puns are jokes based on words that sound the same. You've probably noticed that many words in English which are spelt in different ways and have different meanings are pronounced in the same way. Think about the name of the restaurant: "plaice" is a kind of fish so our restaurant is "the place" to eat fish. Butchers sell meat – so we'll "meet you there" – and opticians look after our eyes in a scientific way – so eyed – iology (ideology) is a name that fits. Hairdressers shear (cut) your locks (hair) and comb it – say the three words together quickly and you have the name of a famous detective. In shop titles and adverts, puns are used to get our attention.

    Puns are very old. The ancient Egyptians and Romans liked to pun. Shakespeare uses many puns in his plays – King Richard the Third (the son of York) brings "glorious summer" – just think about a word that has the same sound as son.

    Many people enjoy a good pun (pun / fun for all the family!) – others hate them. Puns aren't really designed to make you laugh. Here are some puns that might leave you asking for no more puns please. Have you heard about the bears who voted in the North Poll? Or the cheetah (印度豹) who couldn't be trusted at cards? Or how about the clever little Australian animal that had lots of koalaifications or the camel (骆驼) with no humps (驼峰) that was called Humphrey (and so was free of humps...)

    Puns can be funny but they sometimes make important points. Here's a fashion tip: "skinny genes make skinny jeans": so don't worry if your jeans don't fit. Look at your parents!

    An extremely enthusiastic truth seeker who runs the YouTube channel Bright Insight claims（声称）to have found the mysterious city of Atlantis and insists that its true location has been hiding in plain sight for thousands of years.

    In a video, YouTube blogger Jimmy Bright argues that the Richat Structure, a geologic dome（穹状物）in northwest Sahara also referred to as the Eye of the Sahara, is the most likely location of Atlantis.

    He mentioned measurements from the famous Dialogues of Plato, which gave birth to the mystery. The Greek philosopher（哲学家）claimed that Atlantis was a long-gone kingdom, which stretched into Europe as far as Italy and into Africa as far as Egypt thousands of years ago. The giant island was said to be wiped off the face of the planet by a natural disaster “in a single day and night of misfortune”.

    At first sight, this has nothing to do with the land-based Richat Structure, but Jimmy claims that the so-called Younger Dryas theory could be a possible explanation. According to it, a massive change in global temperatures caused unexpected climate change and sea level to rise.

    In what can be viewed as another proof to the Sahara theory, the diameter（直径）of the Richat Structure's outer circle is 23.5 km according to Google Map's measurements, which matches those mentioned by Plato — 127 stadia, which is roughly 23.5 km in today's terms.

    Another thing that helps solve the mystery is a theory that the Eye of the Sahara closely matches the description from Plato's dialogues. The ancient philosopher wrote that the main city of Atlantis consisted of circles of water and land, which, Jimmy said, looks very similar to the circular form of the Richat Structure.

    Although the majority of researchers believe that Plato's story was nothing but a moral story used to describe a failed idea of seeking power and searching for fortune, it has raised quite a few theories, Since the Middle Ages, explorers have been pointing fingers at different places around the world, including the Atlantic Ocean and the Mediterranean Sea, with the most amazing theories linking the location of Atlantis to the Antarctic and the North Sea.
