Ⅷ.阅读理解。
A lot of people play sport,but very few people become sports professionals,即专家。If the sport isn't going to be your future,then why should you play it? Why should you practise it every day? Why should you work hard and feel sore,即酸痛的,the next day? Wouldn't it be better to forget sport and only focus on your lessons? In fact,there are a lot of reasons for playing sport.
First of all,playing sport is a great way to exercise. Exercising keeps you healthy and strong. When you exercise,your body makes endorphins,即内啡肽,to give you more energy and make you feel happier.
Also,playing sport teaches young people how to talk with others and work as a team. It teaches young people to respect their coaches,即教练,teammates and players from other teams. Many reports say that playing sport helps young people stay out of trouble. If a young person plays sport,he or she may have few problems. This is because playing sport teaches people rules. It also teaches people that if they work hard,they will succeed.
Another good reason for playing sport is that it makes people leave their houses. Now,a lot of people watch TV or play video games too often. When you play sport,you can go out and exercise in the sun. You can breathe in,即吸入,fresh air. All of these things are important.
Maybe you're not going to become a sports professional,but that doesn't matter,即无关紧要。Playing sport will help you become a great and happy person.
