爸爸，你多次吸烟，看电视的时候、吃饭的时候吸。我在一旁看着十分担心、焦急。有一次我问你是主动吸烟的害处大，还是被动吸烟大呢？是被动吸烟的害处大。
爸爸，你一吸烟就咳嗽。爸爸，你一吸烟就让我来闻，那味道难闻极了，妈妈为了不让我闻，就让你戒烟，可你就是不听。
爸爸，烟草燃烧后，冒出的烟雾中含有20多种毒素。有资料表明，全世界每年因吸烟死亡达250万人之多，烟是人类第一杀手。长期吸烟者，肺癌的发病率比不吸烟者高1020倍，喉癌发病率高23倍，循环系统发病率高3倍，气管炎发病率高28倍。与吸烟者共同生活的人，患肺癌的几率比常人多处6倍。爸爸，以上数据是证实的，也是可怕的。
爸爸，我知道你爱我和妈妈，为了我和妈妈的幸福。您就戒烟好吗？香烟里含有20多种毒素，其中有尼古丁，一支香烟中含有的尼古丁可以毒死一只小白鼠。爸爸，吸烟有害健康！
爸爸，祝你早日戒烟。我相信你！
i attended jacks birthday party tonight. after dinner, jack gave cigarets to our boy students present.
at the important moment, i stop them ant told them the bad effects of smoking: firstly smoking is a waste of money and its greatly harmful to our health. and it can lead to fires easily.so we should not smoke at all.
but it seemed helpless and they wouldnt listen to me. somebody even said that body and health belonged to themselves and its up to them to decide whether to smoke or not. i told him calmly, even if you have the right to harm your own body, but it doesnt mean that you have the same right to harm others.
at last, they agreed with me, and some students said that they would never smoke any longer.
for the next one hour, we danced and sang happily, and nobody did smoke again.i felt very happy that my classmate all understood the harmness of smoking.
it is very uncomfortable to inhale the smoke of a cigarette smoker. i know this for a fact, since my father smokes a lot. when we are together in a a room, the smoke he exhales fills my lungs and also makes my eyes water.
if possible, smoking in public should be banned altogether, because it is unfair for non-smokers to go through the ordeal of breathing smoke-filled air. so it is very inconsiderate of people to smoke in front of others. in airplanes, people who smoke are separated from passengers who dont. for the sake of everybodys health, i think this should be done in other public places too.
