Life is like a box of chocolates, and you never know what you’re going to get. Twelve-year-old John Wilson had no way of knowing that his life was about to change completely when he walked into his chemistry class on a rainy day in late October 1931. The class ____ that day was to show how ____ a container of water would bring oxygen bubbles (气泡) to the surface. The container John was about to heat, ____, was not like the containers students everywhere had used. Someone had been ____ and put the wrong label (标签) on the bottle. And ____ John heated it with a Bunsen burner, the container ____, sending the liquid flying in all directions. John Wilson came away from it, completely ____.
Wilson spent the next two months in hospital. After he returned home, his parents ____a hard time to find a way to deal with the ____ that had happened to their lives. But Wilson did not ____ the accident as a disaster. He knew he had the rest of his life to live. He learned Braille (盲文) quickly and continued his ____ at the esteemed Worcester College for the disabled. There, he not only ____ as a student but also became an accomplished rower, swimmer, actor, musician, and orator.
Many people, faced with the ____ John Wilson met with, would have ____ of their experience. Perhaps they would have considered themselves to be ____ by ill fortune and discouraged in their ____ to do anything significant with their lives. Wilson, however, lost his sight but found a ____. Through his practical action and life attitude, he proved to us ____ that it’s not what happens to us that ____ our lives — it’s what we make ____what happens.

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.”
