三段式的议论文范文：吸烟

   议论文一般采取提出论点，组织论据，进行论证，做出结论的方法对问题进行分析。其中论点、论据、论证是议论文的三段论的构成基础。掌握议论文的论点、论据和论证的写作要求是写好议论文的前提条件。论点是作者的观点或主张，它是议论文的核心，统领全篇，通常在首段提出，论点必须正确、鲜明。为证明论点的正确，作者要摆事实、讲道理，引用名言、研究或实验结果、统计数字等，这些就是证明观点的论据，对论据的要求是确凿、典型、充实。而论证是以论据证明论点的过程，必须严密、合理，论证一般在主体部分展开。同时论证可以采取归纳推理和演绎推理两种常见的推理方式。下面通过一篇文章宋分析一下构成议论文的三段论的结构。请看范文：

     Cigarette smoking has been jeopardizing human health for centuries ever since an English nobleman brought tobacco from the New World back to England and people everywhere in the world have been putting their way to smoky and cancerous death.

     Medical findings have long proved that there is a close link between smoking and bronchial troubles, heart disease and lung cancer because of many harmful ingredients in the tobacco. Yet the governments of most countries pretend to be blind to the lethal effect of tobacco: the answer lies with money. Cigarette smokers are big tax payers. Levying a tax on your cigarettes is just like levying a tax on your daily bread.

    This is absolutely the most shortsighted policy you could ever imagine. While a surprisingly large amount of tax money is accumulated on the one hand, it is paid out in increasingly larger amount on the other. Each year, millions of dollars of special funds are allocated to those medical research establishments on cancer research and on pharmaceutical products to cure people suffering from the disease. Everybody would have less chance of being struck down by heart disease and cancer if smoking were banned altogether by governments at all levels.

     For a start, governments could begin by banning all cigarette advertising (Cigarette advertising is as insidious as it is dishonest. The advertisements always depict virile, clean-shaven young men. In such advertisements, smoking is always associated with the great open-air life, handsome cowboys, and with beautiful girls. We are never shown pictures of real smokers coughing up their lungs early in the morning) and should then launch fierce anti-smoking campaigns. An effective warning say, a picture of an ugly skull--can be printed on every packet of cigarettes that is to be sold, to scare smokers off sucking those cancer sticks.

     Statistics reveal that the number of adolescent smokers in many countries is on the increase. It is therefore necessary that greater effort should be made to inform young people of the horrible consequences of taking up the habit.
