C.           Teen Health  Good health is important to everyone, but it is especiallyimportant to teenagers. Teenagers are moving from being achild to becoming an adult. Some of these changes are easy tosee. Teens are getting taller, their voices are changing, and otherthings. But these outside things are signs of much moreimportant things that are happening inside the teenager’s bodyand mind. Teenage bodies are preparing to become mothers andfathers. Healthy teenagers can hope to have healthy childrenwhen they are older. If they do not take care of their health now,what can they expect in ten years?   The brain and mind of a teenager are also changing.Teenagers are able to understand things that are very difficult,things a younger person could never understand. But usually, noone talks to teenagers about these changes and they do not knowwhat is happening.   Another problem is that there are so many things around ateenager that are dangerous to his health. Cars and motorcycles are probably the biggest dangers. A lot of people die in anaccident before they have a chance to finish growing up.Another danger is tobacco. Tobacco damages a person’s bodyand mind. Once a person starts using tobacco, it is very difficultto stop. Drugs are also a big problem. These things are aroundyoung people all the time and sometimes it is difficult to stayaway from them when all their friends are doing it. It is not easybeing a teenager! ＊ expect 期待 accident 事件 tobacco 菸 damage 損害
