According to the latest data, there are about 1.3 billion smokers all around the world. It’s generally believed that smoking has bad influence on the smokers’ health. I think people should get rid of this bad habit for the following reasons.
从最新的数据显示，全球大概有13亿烟民。人们普遍认为吸烟对人体健康有严重的负面影响。根据以下列出的观点，我认为人们应该戒烟：

First of all, smoking make people live shorter. The cigarettes contain nicotine which can lead to liver cancer, lung cancer and other respiratory diseases. Scientists believe that smoking is the main cause of lung cancer. What’s more, smoking pollutes the air and the passive smokers. The passive smokers usually feel uncomfortable, such as headache, cough or no appetite at all. The World Health Organization said that more than 2.5 million people die of smoking cigarette every year. Secondly, smoking cigarette costs large sum of money. A heavy smoker can smoke up to 5 packs of cigarettes a day. If one pack is 20 Yuan, then it will cost 100 Yuan per day. The money you spend on smoking is 36,500 Yuan for the whole year. If you don’t smoke, you can use the money to do other meaningful things. For instance, traveling, investing. Last but not least, smoking has a bad impact on the smokers’ daily life and their minds. Smoking will affect the relationship between the smokers and their families. For one thing, the smokers want to quit smoking, but it’s hard. And the smokers’ families will be really disappointed if they keep on smoking. Step by step, the smokers will lose self-confident and self-respect. For another, few women are willing to marry with heavy smokers.
首先，吸烟使人的寿命变短。香烟中所含的尼古丁，可导致肝癌、肺癌和其他呼吸道疾病。科学家相信吸烟是引发肺癌的主要原因。而且，吸烟会污染空气和那些吸二手烟的人。吸二手烟的人通常会觉得身体不舒服，比如头痛、咳嗽、没有食欲等。世界卫生组织宣布全球每年至少有250万人死于吸烟。其次，吸烟花费大量的金钱。烟瘾大的人每天能抽5包烟。如果每包烟值20元，那么一天下来就要花费100元，一年就是36500元。如果你不抽烟，你就可以用这些钱去做一些有意义的事情，例如旅游、投资等等。最后，吸烟对吸烟者的日常生活和个人心理都有着严重的影响。吸烟会影响家庭成员之间的关系。其一，吸烟者想要戒烟，但是太困难；而继续吸烟的话，家庭成员会很失望。慢慢的，吸烟者会失去自信和自尊。其二，只有少数女人愿意嫁给那些烟瘾大的人。

Due to the reasons above, I think it’s quite necessary for people to quit smoking and lead to a regular and healthy life.
综上所述，我认为戒烟非常重要。人们应该活得健康有规律。
