Step one 议论文的三要素:
论点是作者在文章中提出的对某一个问题或某一类事件的看法、观点、主张，它要求要正确、鲜明、有针对性。一篇议论文只能有一个中心论点．论点一般在开头提出，然后加以论证．
论据是证明论点正确的证据，要想证明论点的正确，首先，论据必须让人觉得真实、可信，能够充分证明论点。其次，论据要具有典型性，能收到“以一当十”的效果。第三，论据要新颖，尽可能寻找一些新鲜的、能给人以新的感受和启示的论据.一般是以事实为论据，也可以利用成语，格言，名人名言作为论据．论证是议论文中必不可少的部分。一段完整的议论，只有通过论证证明论据和论点之间的内在逻辑关系，才能将论据和论点融为一体，也才能构成一篇完整的、有说服力的文章。
Step two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．分析两种事物的优劣势,阐述自己的观点.
③“我认为……”型．阐述对某一事物的客观看法.如“你对课外阅读的看法 ④“怎样……（how to）”型．分析怎样解决一个问题如“怎样克服学习中碰到的困难”
.⑤ 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．
