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.... What's the author's purpose of writing the passage? A) He wants to ask people to respect the disabled. B) He intends to call on people to do exercise. C) He wants people to know the importance of exercise for the disabled. D) He wants to explain what healthy lifestyles are.

It was a long week for Amanda at school. She stayed after school to work on a special project  three days in a row. When she got home on Friday, she dropped into the chair with a sigh. "What's going on, Amanda?" her dad asked as he was reading the newspaper. "I have to create a webpage for my technology class, and it is taking a lot more time than I thought it would," Amanda answered. Her dad looked over his newspaper and asked Amanda what the webpage was about. "It's about the difference between newspaper news and Internet news," Amanda said and added, "I have to provide information, examples and illustrations ." "Sounds tough; do you have someone to help you?" her dad asked. "I have a partner named Zach," Amanda replied. "We did research on the Internet today and found some pictures to use." Then Amanda explained to her father the main differences: newspaper news is printed on paper, and Internet news is published online; newspaper news is only available once a day, and Internet news is published almost as soon as the news happens; many newspapers don't even print a daily paper, and Internet news is published around the clock. Amanda's dad asked, "Which type of news do you like better?" "I like Internet news better because I like to learn about the news when it happens," she answered. Her dad said, "I still like newspaper news better because I like to hold the paper in my hands and turn the pages." Amanda dropped into her chair again and said, "You are so old school, Dad." Why did Amanda sigh when she came home? A) She failed to pass the exam. B) She was tired of school life. C) She was worried about her school project. D) She made a mistake in her technology class.

People often talk as if shyness is a disease or mental condition that can be cured. I prefer to think of it as an emotional disability. It's something we are born with and something we carry with us in our entire lives. There are too many people, however, who seem to be determined to find some way of doing away with their shyness. In my opinion, it's a waste of time. I don't mean that we should do nothing about it; quite the contrary, I think we need to separate the basic fact of our shyness from our ability to take part in a social environment. Look at one of the most famous shy people of them all, Johnny Carson. This man is painfully shy, yet for decades he made a living talking and associating with different people every night, in front of a national audience. Carson has never done away with his shyness, but he has successfully found a way to deal with it to the extent that he could be, not just a talk show host, but a legend among talk show hosts. Look also at Sally Fields, who has recently admitted her problem with shyness. This is a woman who has appeared in many films, TV shows and interviews, yet in her early years she was so shy that she turned down a lunch invitation from Jane Fonda because she was terribly afraid of meeting her. I guess that our shyness is there because each of us is born with some insecurity and this insecurity prevents us from reaching out to others the way people with a more open personality do. As we grow up and become adults, we allow our social skills to grow and develop. But we are still stuck in kindergarten or elementary school or wherever it was when our shyness took root in our soul. From the passage, we know that Johnny Carson  _  . A) has dealt with shyness very successfully B) has done away with his shyness carefully C) is described as a hero in some legend books D) failed to become a good talk show host
