As we all know, there are many people smoking, although everyone knows smoking is harmful to us. Giving up smoking is not easy but addicted to it is quite easy, that”s why there are more and more people smoking. Smoking and passive smoking is risk factor that leads to various diseases. It has become world”s top 8 causes of death. More than 90% of lung cancer caused by smoking and lung cancer rates of smokers are 18 times over the non-smokers. Besides, smoking also causes angiocardiopathy, digestive system disease, oral disease and so on. In addition, passive smoking causes great concern in recent years. People have known that passive smoking also do great harm to human, too. Therefore, many countries and regions prohibit people from smoking in public zones, in order to reduce the harm of secondhand smoke. From my point of view, the best way to keep healthy is giving up smoke, for smoker”s own good as well as for others.
眾所周知，即使人們都知道吸煙有害健康，但現(xiàn)在依然有很多人吸煙。吸煙容易戒煙難，這就是為什么煙民的數(shù)量越來越多的原因。吸煙以及被動吸煙都是導(dǎo)致多種疾病的危險因子，煙草已經(jīng)成為全球第八大死因。超過90%的肺癌是由吸煙導(dǎo)致的，吸煙者患肺癌的幾率是非吸煙者的18倍之多。此外，吸煙也會導(dǎo)致心血管病、消化系統(tǒng)疾病、口腔疾病等。此外，被動吸煙在近些年也引起了人們很多的關(guān)注，它也會對人體造成危害。因此，為了減少二手煙傷害，許多國家和地區(qū)都禁止人們在公共場所吸煙。我認為，維持健康的最好辦法就是戒煙，為了自己也為了他人的健康著想
