一、英语议论文写作要点
议论文通过议论或说理来表达作者见解和主张.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,企图说服他人.高中英语议论文的写作要注意以下要点:
1. 论点要鲜明、确切．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．
2. 论据要充分、可靠．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．
3. 论证要严密、得法．归纳法（induction）和演绎法（deduction）是议论文常用的论证方法．归纳法的例子为基础，从几个例子和现象中，归纳出某种道理和看法．例如：报纸是一种媒体（medium ），人们可以从中得到现代信息；电视是一种媒体，人们也可以从中获得信息；广播也是媒体，人们同样可以从中获得现代信息．因此我们可以得出结论，其他媒体，如网络等，一定会给人们信息．演绎法以一个或多个看法为基础，从一般论断，演绎到不同事例，再加以论述，最后再回到一般论断上来．例如：所有的媒体都可以给人们提供信息，网络是媒体，因此人们可以从网络中获得信息．在归纳中要注意使用的例子要充分，不能以点概面．如：（课本高二上p81）：
i borrowed a book from the library last week .it was very boring and difficult .i read only ten pages. therefore, i think that all library books are useless.
评注: it does not have a logical argument .the writer dislike one library book, but not all library books are the same. the writer should not make a general statement (all library books are useless) based on his reactions to one single book.

　　二、 议论文的写作步骤:
1. 引言(introduction)．由于英语作文受时间，字数的限制．因此，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，支援什么，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, 并对此用一两句话分别进行阐述．
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．
例：课本高二上p78第一封信
tutorial center is helpful.
i have studied at a tutorial center for two years. my command of english has improved considerably since i started this course.
at my center, the fees are reasonable. my tutors are qualified teachers. i have been helped a lot by them. they are sincere and kind.
one of my teachers was british. at first, i could not say anything to her. but later i learned how to communicate in english with a westerner.
i think that the tutorial center has given me a lot of confidence in using english.

　　评注: 第一段提出论点, 体现家教中心是helpful(段划线部分) ,主体段分别从几个方面(划线部分)来阐述家教中心的确有帮助,结论段重申家教中心的作用(划线部分),且语句表达与第一段中的不重复.

　　三、议论文的写作模式
1. 议论文的类型
英语议论文根据命题特点，从形式上来看可分为如下类型:
① “一分为二”的观点．如“轿车大量进入家庭后，对家庭、环境、经济可能产生的影响”
② “两者选一”的观点．如，期中考试作文题，“乘火车还是乘飞机”
③“我认为……”型．如“你对课外阅读的看法”
④“怎样……（how to）”型．如“怎样克服学习中碰到的困难”．
⑤ 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．
按照高二上学期的写作要求，学生主要应掌握①②两种类型的议论文的写作．在第①种类型中命题涉及某一事物或现象的正反两个方面：通过正反两个方面的对比，得出结论是利大于弊，还是弊大于利．论证要围绕所要得出的结论来展开，若利大于弊，则有利的一面要多阐述一点．反之亦然．
在第②种类型中，命题要求在a或b两者之间作一比较或选择，两个对象往往各有优势，所以结论部分有两种情况：
a. 要么支持a，要么支持b;
b. a、b优势均难的割舍，只好依情况而定在结论部分说清楚在什么条件选a, 在什么条件选b．
下面重点介绍第①、②种类型议论文的写作模式.
