One possible version：

According to a report, China has the largest number of smoker in the world, with more and more teenagers joining the ranks every year.

The problem has aroused great pubic concern, since smoking is responsible for thousands of premature deaths every year caused by smoking-related diseases. It affects the health of smokers, and meanwhile threatens non-smokers by exposing them to secondhand smoke. Therefore, awareness should be raised about the risks of smoking, and a nationwide ban should be issued on smoking in public places. It is hoped that through these measures, fewer people will fall victim to cigarettes, and more will be able to embrace a healthy life free of smoke.

题目分析：本文是一篇材料作文，在写作时应该先用一句话来总结材料内容，即中国是世界上吸烟最多的国家，而且青少年吸烟的人数也在增加。然后就材料发表看法时应该先提出吸烟的危害the harm of smoking ,可以使用的短语do harm to ,be harmful to ,ruin one’s health 等。接下来要表达作者自己的观点，也就是要戒烟，改掉吸烟的坏习惯，可以使用的短语kick the habit of 、quit smoking 等。因为本文是表达现状，所以在写作时可以使用一般现在时态。为了使句子或段落语义连贯，表达合理准确，可以适当加入一些连接词语。如表达转折的but, however, otherwise等，表达的递进besides, what’s more等，表达因果so ,therefore, as a result等，有时还需要加入一些必要的过渡句子以达到承上启下的效果。

【亮点说明】本文短小精悍，层次分明。作者首先用一个含有with 复合结构的句子来概述材料内容，然后提出了自己对吸烟的反对，观点明确，达到了文章的要求。在文中作者使用了几个长句（并列句、复合句、复杂句、复合复杂句）和短句来表述文章的内容，这种长短句的结合有效地表达了丰富的信息。在文中用了到了原因状语从句since smoking is responsible for thousands of premature deaths every year caused by smoking-related diseases，主语从句It is hoped that through these measures, fewer people will fall victim to cigarettes, and more will be able to embrace a healthy life free of smoke.，这些都显示了作者深厚的语言功底和对语言较强的把控力。
