中文版：

5月31日是世界无烟日，这是一个旨在呼吁人们关注烟草对健康和环境的危害的日子。世界无烟日的起源可以追溯到1987年，当时卫生组织在加拿大蒙特利尔召开了一次国际烟草控制会议，旨在讨论如何在全球范围内减少烟草的使用。自那时以来，世界无烟日已经成为全球范围内的一项重要活动，每年有数百万人参与，以表达他们对烟草控制的支持。

烟草对健康的影响是世界无烟日关注的重点。烟草中含有许多有害物质，如尼古丁和焦油，这些物质会导致许多健康问题，如肺癌、心脏病和呼吸系统疾病等。每年有数百万人死于与烟草相关的疾病。此外，烟草还会对周围的人造成二手烟的危害，对他们的健康造成影响。

为了减少烟草的危害，世界无烟日强调采取措施来控制烟草的使用。这包括提高烟草税、禁止在公共场所吸烟、加强烟草广告的监管等。这些措施有助于减少人们开始吸烟和继续吸烟的可能性，从而保护人们的健康。

May 31st is World No Tobacco Day, a day aimed at calling attention to the dangers of tobacco on health and the environment. The origin of World No Tobacco Day can be traced back to 1987, when the World Health Organization (WHO) held an international tobacco control conference in Montreal, Canada, to discuss how to reduce tobacco use globally. Since then, World No Tobacco Day has become an important global event, with millions of people participating every year to express their support for tobacco control.

The focus of World No Tobacco Day is the impact of tobacco on health. Tobacco contains many harmful substances, such as nicotine and tar, which can cause many health problems, including lung cancer, heart disease, and respiratory diseases. Tobacco kills millions of people every year from tobacco-related diseases. Additionally, tobacco also poses a risk to the health of people around them through secondhand smoke.

To reduce the harm caused by tobacco, World No Tobacco Day emphasizes taking measures to control tobacco use. This includes increasing tobacco taxes, banning smoking in public places, and strengthening the regulation of tobacco advertising. These measures help reduce the likelihood of people starting and continuing to smoke, thereby protecting their health.
