Smoking is one of the worst things kids or adults( 成年人 )can do to their bodies. Yet every day nearly 4,400 kids between the ages 12 and 17 start smoking. Why? There's more than just one simple answer. Some kids may start smoking just because they’re curious. Others may like the idea of doing something dangerous – something grown-ups don't want them to do. Still others might have grown up around lots of people who smoke and they might think it’s the way to act like an adult. Tobacco( 烟草 )contains nicotine( 尼古丁 )which causes a good feeing --- but that feeling only lasts tor a little while. If you start to use nicotine, your body and mind will become so used to it that you’ll need to have it just to feel OK. It’s very hard to stop doing it, even if you want to. Smoking causes lots of diseases, like heart problems and cancer. That's true, but sometimes kids can’t really think that far into the future to worry about an illness they might not get for 20 years. So let's talk about the problems that might influence kids more quickly: ● yellow teeth ●bad breath ● more coughs ●difficulty keeping up with friends when playing spots ●empty wallet---- smoking eats up a lot of money !
