1、英语四级议论文写作辅导1 议论文的格式：议论文的格式应由三个部分组成： 立论部分； 论证部分； 结论部分。一般说来，议论文可分三个基本段落来写：第一段引出话题；第二段立论且加以论证；第三段给出明确的结论。第二段是中心段落，应试者应将主要的内容放在第二段中，同时也要注意开篇及结尾段落的完整性，且应尽量做到首尾呼应，切忌前后矛盾。2 段落的统一性及语篇的连贯性（1） 段落的统一性英语段落有一大特点，即一个段落只涉及一个主题（甚至只是一个主题的某个方面）。段落中的一个句子点出主题并说明作者对该主题的看法，而其它所有句子都是为展开该主题而给出的事实、例证、推理，它们与主题紧密相关。段落中不应有一个与主
2、题无关的句子。英文段落的这种各个句子与主题的关联性被称作段落的统一性。请看以下两例：(1)Birds build their nests in all kinds of places. Some are high in trees, on the sides of buildings or on the top of hills while others on the ground, in fields or by stream banks. Birds also use various nesting materials to build their nests, including sti
3、cks, mud, stones, grass and so on. Some birds are able to change to be suitable for different conditions. Theyll build their nests wherever they can find a spot and use whatever materials they can find. But other birds will build their nests only in certain places and use only certain materials.（2）
4、语篇的连贯性英语议论文的段落多采取直线展开式，即段落开始直接切入主题，并给出事实、例证、推理等。英语议论文段落这种展开方式是形成其语篇连贯的基础。语篇的连贯是指段落中各句的意义通过某种有序的排列（如时间顺序、因果顺序、逻辑顺序等）而相互关联。在论述该段落主题的时候，每后一个句子都是建立在前面一个句子的基础之上的。如果去掉段落中的一个句子，这种连贯便会受到影响，就会造成读者在理解上的困难。3 议论文中心段落的主题句及其论据、议论文中常用的词句与短语（1） 议论文中心段落的主题句及其论据一篇议论文能否获得高分与其中心段落主题句的质量不无关联，而主题句质量的高低则又取决于审题的好坏和论据的选择（即所
5、选的论据在逻辑性、说理性、准确性及与主题内容的关联性等方面是否都经得起推敲）。需要明确的是，中心段落只应有两个组成部分：段落的主题句和支持主题句的论据。段落的主题句也应有两个部分组成，即：主题句=主题+作者对主题的看法或态度，两者缺一不可。假设应试者被要求写一篇有关吸烟的议论文，那么 SMOKING 就是中心段落的主题。请看下面这个主题句：Smoking is a habit of many men.该主题句暴露出两个问题：（1）作者审题不清；（2）作者没有表明对主题的看法或态度。一般说来，议论文要求应试者阐明自己对某问题的看法或态度。因此当我们拿到议论文的题目以后，要认真审题，权衡某事的利与
6、弊，然后确定我们的立场。如何构建段落的主题句呢？拿到议论文的题目以后，经认真审题后，用英文列出你所能想起的与主题有关的例证。我们还用吸烟这个话题为例：SMOKING1 Smoking can cause such a disease as lung cancer.2 Reports say that merely 3 grams of nicotine can kill a large animal.3 Experts say that smoking one cigarette can reduce ones life by about 15minutes and that chain sm

9、g one cigarette can reduce ones life by about 15 minutes and that chain smoking is far more hazardous. Recent findings of medical research show that even a tiny drop of nicotine (about 3 grams in weight) can kill a large animal like a horse. Some medical reports have also proved that heavy smoking w

Cigarette smoking not only jeopardizes the physical health of a smoker, it also affects the health of a nonsmoker who passively inhales the polluted air into his or her lungs when he or she is ex

The impact on such passive smokers (also called second-hand smokers), according to the experts in the medical field, can be even more damaging, and that is why smoking is usually prohibited in most public places.
