[Q]: Article: When you make a mistake, big or small, cherish it like it's the most precious thing in the world, because in some ways, it is. Most of us feel bad when we make mistakes, beat ourselves up about it, feel like failures, get mad at ourselves. And that's only natural. Most of us have been taught from a young age that mistakes are bad, and we should try to avoid mistakes. We've been scolded when we make mistakes--at home, school and work. Maybe not always, but probably enough times to make feeling bad about mistakes an unconscious reaction. Yet without mistakes, we could not learn or grow. If you think about it that way, mistakes should be cherished and celebrated for being one of the most amazing things in the world. They make learning possible; they make growth and improvement possible. By trial and error--trying things, making mistakes, and learning from those mistakes--we have figured out how to make electric light, to paint the ceiling of the Sistine Chapel, to fly. Mistakes make walking possible for the smallest _ , make speech possible, and make works of genius possible. Think about how we learn:We don't just consume information about something and instantly know it or know how to do it. You don't just read about painting,or writing,or computer programming,or baking, or playing the piano, and know how to do them right away. Instead, you get information about something, from reading or from another person or from observing usually...then you construct a model in your mind...then you test it out by trying it in the real world...then you make mistakes...then you revise the model based on the results of your real world experimentation...and repeat, making mistakes, learning from those mistakes, until you've pretty much learned how to do something. That's how we learn as babies and toddlers, and how we learn as adults. Mistakes are how we learn to do something new--because if you succeed at something, it's probably something you already knew how to do. You haven't really grown much from that success--at most it's the last step on your journey, not the whole journey. Most of the journey is made up of mistakes, if it's a good journey. So if you value learning,if you value growing and improving,then you should value mistakes. They are amazing things that make a world of brilliance possible.
Question: Why do most of us feel bad about making mistakes?
Options: (A) Because mistakes make us suffer a lot. (B) Because it's a natural part in our life. (C) Because we've been taught so from a young age. (D) Because mistakes have ruined many people's careers.
[A]: C

[Q]: Article: At the recent O&P Extremity Games, I had the opportunity to observe a new generation of athletes with disabilities who were skateboarding and rock climbing. These young people really showed the promise of how rewarding physical activities are! We disabled can - and should be -- as active as anyone else. When we get and stay active, we will feel better, be able to do more, have healthier bodies, and look better. It is a fact that exercise actually produces energy and builds on itself. The more we exercise, the fitter our bodies are, and thus the more energy we have to enjoy recreation and the pleasure of life. Not everyone is cut out to be a competitive athlete, but there are things that we can do to strengthen our physical well-being. Experts recommend that spending as little as 30 minutes each day on physical activities provides benefits including lower risk of heart disease, cancer, high blood pressure, diabetes and other serious diseases. Taking steps to become physically fit does not have to mean acquiring expensive training equipment or a gym membership. Exercise can include simple walking and running, gardening, cleaning the house, swimming, tennis, bicycling (stationary or on the road) and so on. The key is to do it on a regular basis. Healthy lifestyles also require good nutritional habits. When choosing foods, nutritionists advise whole grains, flesh fruits and vegetables, fish, and lean cuts of poultry and meat. The benefits of drinking eight full glasses of water a day are also _ . Water provides the means for nutrients to travel to all our organs, improves skin tone , regulates body temperature and contributes to muscle strength and control, which is confirmed by scientists. Fitness results in completing the tasks of daily living, working a full day, and still having energy to participate in recreational activities. By being fit, you'll find that you enjoy recreational activities even more because you won't be tired or suffer from gore muscles. It is time, folks, to get moving. So let's all get out there and do some exercise!
