如何写议论文
议论文主要针对某一观点或问题（一般为有争议的观点或问题）发表议论和看法，因此写此类文章时要考虑的论据多为正反两个方面。
通过对有争议的观点或问题的不同看法进行比较，然后进行分析和评论，最后提出自己的看法，表达自己支持或反对的态度并加以论证说明，得出结论。
1．在文章的开头提出有争议的观点（一般提出两个相对的观点，然后客观地对其进行评析）。
2．接下来可用一个或两个段落分别展开论述。
在每段中，均可用主题句来点明论点，并对这些论点进行比较和对比、分析和评论。
3．文章结尾对所论述观点进行客观、合理的评论，提出自己的看法、建议；
或者也可以将不同观点相互融合，选其可取之处，形成自己独到的观点。
