At the important moment, I stop them and told them the bad effects of smoking: firstly Smoking is a waste of money and it's 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 wouldn't listen to me. Somebody even said that body and health belonged to themselves and it's 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 doesn't 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.
我今晚参加了杰克的生日派对。晚饭后，杰克给我们的男同学吸烟。
在重要的时刻，我阻止并告诉他们吸烟的不良影响：首先，吸烟很浪费钱，它对对我们的健康危害很大。它会很容易引起火灾。所以我们不应该吸烟，所以我们不能吸烟。
但很无奈似乎他们不听我的。甚至有人说身体是自己的，这是是否吸烟由他们自己说了算。我平静地说，“即使你有伤害自己身体的权利，但这并不意味着你要伤害别人的权利。”
最后，他们同意我的看法，一些学生说他们不会再抽烟了。
在接下来的一个小时里，我们跳舞，唱歌，没有人吸烟了。我感到非常高兴，我的同学都知道了吸烟的危害。
