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. 1..
Wear the Right Shoes
The right shoes will depend on the road.You should wear 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). 2.when trying out a pair of running shoes, check the fit, feel and ride of the shoes.These elements 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! 3. 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
4. Start your run into the wind and finish running with it at your back. This keep icy wind from blasting (用力撞击) your face. To prevent any injuries or accidents, break your run into small parts. 5.You can use certain creams on the nose and cheeks to prevent frostbite. 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. It’s hard to run if it’s too windy.
B. It also helps to keep the skin protected from the wind.
C. Your shoes should fit very well so you don’t slip
D. Here we are giving you important tips to remember.
E. Running makes you warm.
F. Don’t run in the wind.
G. Warm-up prevents injuries.
Traditionally, robots have been hard, made of metal and other rigid material .But a team of scientists at Harvard University in the US has managed to build an entirely soft robot—one that draws inspiration from an octopus (章鱼).
Described in science journal Nature, the “Octobot” could pave the way for more effective autonomous robots that could be used in search, rescue and exploration. “The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots”, the study’s authors wrote.
Robots built for precise, repetitive movements in a controlled environment don’t do so well on rough terrains (地形) or in unpredictable conditions. And they aren’t especially safe around humans, because they’re made out of hard and heavy parts that could be potentially dangerous to their users.
So researchers have been working on building soft robots for decades. They’ve taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.
But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it’s still a grand challenge to construct flexible versions of essential parts, such as a source of power.
“Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration,” Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology Center for Micro-BioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.”
1.What’s the special feature of “Octobot”?
A.It’s very small. B.It’s made of metal.
C.It’s soft. D.It looks like an octopus.
2.What’s the shortcoming of traditional robots?
A.They’re hard to control. B.They can’t behave well all the time.
C.They can’t predict conditions. D.They’re too heavy to move.
3.Which of the following is wrong?
A.The original robots can work on rough land well.
B.The original robots may hurt people.
C.It’s tough to invent an absolutely soft robot.
D.The soft robots might improve the quality of human life.
4.One of the biggest challenges is to build Octobot’s ________.
A.silicone body B.complex structure
C.precise movements D.flexible power source
5.What’s the possible application of “Octobot”?
A.Medical research. B.Life rescue.
C.Machine operation. D.House cleaning.
Despite being used by 1.34 billion people each year, traveling on the Tube in London can actually be quite lonely. An unwritten rule encouraging reticence (沉默寡言), mixed with classic British reserve, means that even though you’re packed into enclosed space with hundreds of other people, the morning trip can leave you feeling somewhat lonely.
One London resident, however, is trying to change this. “You get on the Tube and it’s completely silent and it’s strange,” says Jonathan Dunne, an American living in London, who has started a campaign of giving out badges (徽章) with the slogan “Tube chat?” last month, encouraging travelers in London to get to talk to one another. “I handed out 500 badges during rush hour in a city of 8 million, expecting most of them to be thrown away, but after about 24 hours it completely snowballed,” he says. Dunne and his “Tube chat” campaign have been reported by media across the world, seeing TV interviews in Sweden, Brazil and the UK, as well as countless website, newspaper and magazine appearances.
Although Dunne says he’s received mostly positive responses, there are always exceptions.
Londoner Brian Wilson responded with a campaign of his own, handing out 500 badges with the words “Don’t even think about it” on them. “I can’t stand the idea of having to talk to strangers on the Tube on my way to work,” he said.
Michael Robinson, 24, a student from London, agrees. “Being on the Tube is the only peace and quiet some people get on their journeys to and from work. It doesn’t need to be spoiled by people coming up and chatting to you,” he says.
“People assume that I just walk up and talk to strangers, which I don’t, but it’s been a great way to meet people you would never have normally spoken to,” Dunne says. So if you ever end up using public transport in London, why not say hello to the person next to you? Just make sure to check for a badge first.

Every November, Time magazine picks out what it calls “The 25 Best Inventions” of the year. Here, Teens has chosen some of the most interesting ones.
Ember Mug
It’s hard to always keep coffee at the right temperature, especially in winter. It’s too hot to drink at first, but before we know it, it gets too cold and loses all its taste. The perfect level of warmth for a cup of coffee only lasts for 37 seconds, which makes the Ember Mug a great innovation. It keeps your coffee or tea at a certain temperature, anywhere between 45℃ and 62℃ once you set it through a smart-phone app.
Tasty One Top
TV cooking shows make cooking look so easy, but it’s almost impossible to get the recipes to cook the same as how the professionals cook. However, the Tasty One Top DIY cooking companion is here to help. Developed by Buzzfeed, the cooker can be connected to a smartphone app, which has more than 1,700 recipes and videos. You choose a recipe and the app will let the cooker know what to do. For example, it’ll tell you when to turn your steak or when to add certain ingredients.
Jibo
Smart speakers from companies like Amazon and Xiaomi have added a lot of fun to our lives, but they’re still just faceless speakers. However, Jibo, developed by MIT professor Cynthia Breazeal, has brought smart technology to life. Said to be “the world’s first social robot for the home”, Jibo looks like a cartoon character. Inside its “head”, there are various sensors (传感器) and cameras, which allow it to recognize faces and speech. It can also set alarms, remind you of important things, tell you the weather and read news or messages from your friends and family.
