如何写议论文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几点： 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。归纳法和演绎法是议论文常用的论证方法。归纳法以例子为基础，从几个例子和现象中，归纳出某种道理和看法。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。
【常用表达】第一部分，套用相关句型来引出议论。1. Recently, ur class have had a heated discussin abut These years, sme students are interested Nw, sme peple hld the view I'm writing t tell yu abut the discussin we have had There are tw pinins n it.6. Opinins are divided n the questin.

第三部分，引用表示因果关系的关联词语、总结性的语句强调和重申提出的观点，或者引用某些特定的短语和句型来揭示观点、礼貌地征求对方的建议。1. In a wrd, shrt, brief, As a result, , N dubt ding smething is n dubt S in a wrd, we shuld..., nly in this way can Generally speaking, mst students think we shuld...
6. In fact/As a matter f fact, we S, fr smething, I suggest that we shuld In my pinin, I I have my wn view abut it, and I Persnally, I believe it Nw, we really dn't knw what t d abut it. Culd yu tell us sme gd advice and help us ut?
