如何写表达观点的文章
　　高考英语应用文写作中, 发表观点, 议论情景是常见的书写手法。发表议论就是通过议论或说理来表达作者的见解和主张, 作者对某一问题持有一种看法, 为了使读者同意自己的看法, 提出若干理由, 试图说服他人。
发表议论时, 我们要注意三个要素: 论点、论据、论证。
议论文的类型:
1. “一分为二”的观点: 从两方面去分析一个问题, 然后阐述自己的观点。
2. “两者选一”的观点: 分析两种食物的优劣势, 阐述自己的观点。
3. “我认为……”型: 阐述对某事物的客观看法。
4. “看图(表)”作文: 通过阅读图表中的数字与项目得出一个结论或形成一种看法。
如: 我们要写一篇关于支持有机农业的议论文, 需要注意哪些方面呢?
(1)说明、论述时要注意动词时态, 属于过去发生的用一般过去时, 属于经常发生的应用一般现在时。
(2)句子结构要有变化, 不要总是用一个句型“I am. . . and I agree. . . and I. . . ”
(3)熟练掌握一些固定句型和表达方式。
(4)熟练使用一些数据、百分比等作为观点的支撑。
(5)注意将作文的论据分层次展示, 然后列举出相应的细节去支撑主要观点。一个中心论点通常有几个分论点支持, 不同层次之间要分明, 过渡清晰自然。
(6)观点要鲜明, 一篇文章要有一个明确的中心论点。最后一段总结, 得出结论。整篇文章语言要简洁有力, 一般不采用口语。
议论文的写作步骤:
(1)引言(introduction)。由于英语作文受时间和字数的限制, 因此, 审清题意之后在引言段中作者就必须简单解释要讨论的问题, 并明白地亮出自己的观点, 如提倡什么, 支持什么, 反对什么。
(2)主体段(main body)。主体段是议论的过程, 作者必须有足够的证据( adequate proofs)来论证自己的观点。一般可提出一个或两个 proofs, 并对此用几句话分别进行阐述。
(3)结论(conclusion)。结论段可以用一两句话来结束文章。同时要注意与引言段呼应, 但不能照搬前面的原话。
【典例分析】
　　关于有机农业和化学农业, 你们班举行了一场辩论。请结合你们的讨论结果, 写一篇支持有机农业的英语作文, 词数不低于80。
注意要点:
1. 化学农业的危害;
2. 有机农业的优点及理由;
3. 讨论的结果和大家的期待;
4. 根据自己掌握的相关知识, 批判性地发表自己的观点。

　　It is obvious that using chemical fertilisers has many disadvantages. Above all, there is no doubt that the chemicals staying inside the crops can lead to cancer or other illnesses. Besides, the vegetables grow so fast that they contain little nutrition.
　　Organic foods are becoming increasingly popular with customers. There are many reasons for this. The first one is that as people are richer, they attach great importance to health. Secondly, organic produce simply uses natural fertilisers, making vegetables and fruit tasty and nutritive. Moreover, the produce grows in clean water and never uses pesticides, which is beneficial for our health.
As a saying goes, health is the first wealth, so it is wiser to choose organic food.
