高中里有很多学生吸烟,原因可能是他们觉得手中有一支烟看上去很酷或者显得更成熟。但是,不吸烟的原因有很多。吸烟有害我们的健康,对我们的心脏和肺很危险。很多疾病都是由香烟引起的,而且烟的味道不好闻。二手烟对周围的.人也很危险。因此,公共场所禁止吸烟是很多国家的一项严厉规定。最重要的是,一旦你上瘾了就很难戒掉了。所以,为了每个人的健康,我们必须远离香烟。
Today smoking is a widespread habit ali over the world. Not only the old, the youth, but also middle school students have been engaged in smoking. Many of them think that smoking is a smart symbol.
However, smoking is harmful to one's health. It contributes a lot of lung cancer, from which many people have died in the past years. It can also cause many other diseases. In a word, if you smoke, you do have a much greater chance of losing your health. Furthermore, scientific research shows that smoking is not only harmful to smokers themselves, but also a threat to public health, especially to women and children. Therefore, many countries have made laws forbidding smokers to smoke m public places such as cinemas, stations, hospitals, and so on Giveup smoking! If you don't smoke, don't start. Give upsmoking for the sake of your health, for the sake of your family, and for the sake of the whole world.
当今吸烟是一个世界范围内的习惯。不仅是老人,青年,而且中学生都吸烟。他们中的许多人认为吸烟是一种潇洒的象征。
然而,吸烟有害人的健康。它会引起肺癌,其中许多人在过去的一年都死去了。它还可以造成许多其他疾病。总之,如果你吸烟,你有更大的机会失去你的健康。此外,科学研究显示,吸烟不仅对吸烟者有害,而且对公众健康构成威胁,尤其是对妇女和儿童。因此,许多国家都制定了法律禁止吸烟如电影院,车站,医院等公共场所禁止吸烟,如果你不抽烟,不要开始。戒烟吧,为了你的健康,为了你的家庭,和世界。
在22世纪,地球人口暴增,人类在把大面积的森林、田园变成了高楼大厦时,他们不知道,自然危害正向他们逼近。人类破坏原始森林与地球植被,使地球的沙漠化进程大大增加,地球气候异常,工业化进程破坏环境、污染水源、而厄尔尼诺现象严重威胁人类生存。
现在的我在国际科研小组工作。今天,我在开会时向大家提出了我冥思苦想后的一个计划:“克隆一个‘健康’的地球。”我还担心不能通过。提出意见后,大家都拍手叫好,一致通过。
得到允许,我们开始忙碌起来。采集现在地球上的仅剩的资源和各种克隆地球所需要的基本成分,如:水、土、动植物……经过—个月的'不懈努力,我们竟然克隆了一个别开生面小地球,我们帮小地球作了一系列的检查扫描、计算、测量……这个新地球和现在的地球的结构十分相似。几天后,新地球“长大”了,科研小组帮它作了最后的检查:空气清新、温度合适、资源丰富,分布广、动植物多……得出结论:一切正常。然后我们把它送到与旧地球相对的赤道。
新地球的生长速度极快,利用新地球的一部分树林吸掉之前旧地球二氧化碳,排出氧气,原本旧地球那黯然无色的天空终于露出了蓝宝石般的天空。大部分国家“吃一堑,长一智”统统拆除污染性工厂,改造为无污染环保工厂。这一举动,让地球母亲恢复了之前的原貌:蔚蓝的天空,清澈的河流,清新的空气……万紫千红,鸟语花香。也让人们得到教训,自觉保护环境。而新的地球也为人口暴增的问题迎刃而解,我们科研小组也被联合国成为“最佳科研小组”。
通过这一次教训,我想跟21世纪的人们说:“地球的命运掌握在你们手里,而命运是会改变的。请保护地球,不要让世界出现第二个地球!”
