Smoking and Health-吸煙與健康

　　人人都知道吸煙有害健康。那些吸煙過度的人一般都活不長(zhǎng)。吸煙可能引起多種疾病，其中最嚴(yán)重的是肺癌。另外，吸煙的人還損害了那些不吸煙的人的健康。如果所有的煙民都戒了煙，那么我們就可以享受更清新的空氣，也就更健康了。

　　Everybody knows smoking is bad for health. Those who smoke too much may not live long. Smoking may cause many diseases. The most serious one is lung cancer. Smoking can also do harm to those who don't smoke, If all smokers give up smoking, we can enjoy clearer air.
