對同一件事情，人們常有不同的看法，即正反兩種觀點。在寫作時，常使用一般現在時。寫作格式一般是：提出問題→兩種不同觀點→對兩種不同觀點的論據（理由）逐項作對比。有時題目會要求說出自己的觀點，可在結尾段加上自己的觀點并簡要說明理由，最好不要重復前面的已談到的理由。寫作方式一般采用集中比較。
對比式議論文要求考生從正反兩個方面來論證某一觀點，對這類題型，一般有三個主要部分，即：
topic sentences：引入，即主題部分，要針對題目要求,對現象進行概述,提出自己的論點,這部分一定要簡明扼要,往往三兩句即可。
supporting sentences：展開，要圍繞自己提出的論點進行深入的闡述,可以通過舉例、比較等來支持自己的論點。（正反論證,持之有故。在認真審題、提煉出論點之后,接下來應當擺出正反兩方面的論點和論據,也就是說,用原文所給的足量事實來支撐各自的觀點,如果題目沒有給定更多的內容,這時需要自己深入思考,挖掘比較兩者的不同點,然后分別進行論證,務必做到言之有據,持之有故,自圓其說。）
concluding sentences：結論，重申自己的觀點,它是討論的最終結果,也是對全文進行總結,但不要重復開頭引入
部分,最好換一種方式或句型來寫。(在一篇120字的文章中，結論文通常只能有一至兩句。結論只是用來總結文章之前的意思，除非只是一個次要觀點，否則不要在這段內提出任何新見解，但如題目要求的話，您可在結論上提出您的建議、推薦、介紹和解決方法.)
通常分為四個步驟來寫：
第一段 文章開頭，提煉論點,搭建框架
第二段 闡述提綱中列舉的第一種看法，給出理由或者舉例說明:主題句＋理由/舉例1+理由/舉例2+理由/舉例3
第三段 闡述提綱中列舉的第一種看法，給出理由或者舉例說明:主題句＋理由/舉例1+理由/舉例2+理由/舉例3
第四段 表明自己的觀點結束全文:在結尾的時候，一定要表明自己的觀點。
注意事項：
1.巧用連詞、銜接自然。寫比較式議論文時,為了使文章結構緊湊,句子銜接自然,邏輯性和連貫性強,可以借助一些連接詞來過度，使上下文讀起來流暢。常用于展開論證的連詞或詞組有 first of all, besides, in addition, however,what's more等,用于結論部分的furthermore,moreover,連接詞或詞組有:in short,in a word,in conclusion,on the whole,to conclude,on one hand,on the other hand等。
2.查缺補漏,愈加完善。完成作文之后,要注意檢查一下,在檢查時,把握好以下幾個方面的問題,看看有沒有錯誤:(1)時態是否一致,特別是復合句,要弄清楚主從句的時間關系;(2)搭配問題,注意介詞搭配和動賓搭配;(3)詞性誤用,根據詞語在句子中擔任的不同成分,選用不同的詞性;(4)關系一致問題,既要注意主謂一致,又要注意代詞一致,分詞邏輯主語和句子主語一致等問題;(5)連接詞問題,對于不同的句式,既要防止連接詞的重復,又要防止它的缺省。 掌握了以上對比式英語議論文的基本框架和技巧之后,平時多加練習,多模仿、學習一些優秀的英語范文,多背誦一些經典句型,多積累一些中高級詞匯,恰當運用一點銜接過渡手段,就一定能寫出內容詳實、層次分明且結構完整的文章。
寫作方法
1.Strategy:
Contrast: It explains how persons/things are different.
Comparison: It explains how persons/things are similar.
2. What connecting words or phrases can we use to develop contrast and comparison?
Contrast: while, however, but, be different from, unlike, on the contrary, just the opposite
Comparison: similarly, just like…, alike, likewise, equally, in the same way, both, also
Ex. Combine 2 sentences into one.
I wrote letters to my friends. I send emails to my friends.
I used to write letters to my friends, but now I send them e-mails.
Unlike before when I wrote letters, I send e-mails to my friends now.
3. Two ways to develop comparison and contrast (對比寫作一般有兩種方式)
Topic by topic structure:集中比較或對比（集中說明一個對象的諸種特征）
Point by point structure:逐點比較或對比（一條一條地說明兩者的異同）
Ex. 2 Explain the table in English.
children eat out at weekend western food
parents eat out at weekend Chinese food
○1 Topic by topic
Children like to eat out at weekend. They are usually interested in western food. In the same way, parents also eat out at weekend. But they usually go to a Chinese restaurant.
○2 Point by point：Children and parents both like to eat out at weekend. But children are interested in western food while parents prefer Chinese food.
Example1:
1.只給出主題，題目沒有更多的內容，這時需要自己深入思考,挖掘比較兩者的不同點,然后分別進行論證,務必做到言之有據,持之有故,自圓其說。
2.要求論述兩個對立的觀點并給出自己的看法。○1有一些人認為……○2另一些人認為……○3.我的看法……
The topic of ①___________（主題）is becoming more and more popular recently. There are two sides of opinions of it. Some people say A is their favorite. They hold their view for the reason of ②___________（支持A的理由一）What is more, ③___________理由二). Moreover, ④___________ (理由三).
While others think that B is a better choice in the following three reasons. Firstly, ___________ (支持B的理由一). Secondly (besides),⑥___________（理由二）. Thirdly (finally),⑦___________ (理由三).
From my point of view, I think ⑧___________（我的觀點）. The reason is that ⑨___________ (原因). As a matter of fact, there are some other reasons to explain my choice. For me, the former is surely a wise choice.
3.給出一個觀點，要求考生反對這一觀點
Some people believe that ①___________（觀點一）. For example, they think ②___________（舉例說明）．And it will bring them ③___________ (為他們帶來的好處).
In my opinion, I never think this reason can be the point. For one thing,④___________ (我不同意該看法的理由一). For another thing, ⑤___________ (反對的理由之二)．
Form all what I have said, I agree to the thought that ⑥___________ (我對文章所討論主題的看法)．

Sample:
We middle school students have had many tests or exams. We have both achieved success and suffered from failure. Different students take different attitudes to failure.
Some fall in low spirits when they don’t do well in the exams. They usually lose heart and no longer study as hard as before. However, most students take an active attitude towards failure. They encourage themselves to be self-confident. They find out and analyze the causes so that they will no longer make similar mistakes.
As for me, I agree with those with active attitudes. As we all know, failure is the mother of success. Even great men may have failed many times before they succeeded. So we must deal with failure correctly.

One possible version:
Dear Editor,
I'm writing to tell you about the discussion we've had about whether an entrance fee should be charged for parks(提出問題).
Opinions are divided on the question(過渡句). 60％of the students are against the idea of entrance fee. They believe a public park should be free of charge(觀點一). People need a place where they can rest and enjoy themselves. Changing entrance fees will no doubt keep some people away(論據一). What is more, it will become necessary to build gates and walls, which will do harm to the appearance of a city(論據二).
On the other hand, 40％ think that fees should be charged(觀點二) because you need money to pay gardeners and other workers(論據一), and to buy plants and young trees(論據二). They suggest, however, fees should be charged low.
Yours truly

可以看出，這類文章的寫作，首先要提出問題，即雙方討論的問題。接下來提出觀點一，并用一系列論據進行闡明。說明完觀點一之后，再提出觀點二，繼續用論據進行說明。如果需要說明自己的觀點，可接下來說明自己的觀點。
2. 假定你是某中學學生李華。最近，你班同學正在參加《中國日報》21世紀中學生英文報“大家談”欄目的一個討論。本次話題為：父母的收入有沒有必要讓孩子知道?
請你根據下表所列情況給報社寫一封信，客觀地介紹討論情況。
70％的同學認為： 30％的學生認為：
1．父母的收入應該讓孩子知道； 1．父母的收入沒有必要讓孩子知道；
2．知道后，知其來之不易，能夠更加努力學習； 2．如果知道父母收入較好，會助長亂花錢風氣；
3．知道后，可以理解家長艱辛，學會儉省，為大人分憂。 3．知道父母收人后，會以為不用努力，也能靠父母，影響學習動力。
注意：1．詞數：100左右。2．信的開頭已經為你寫好，不計入總詞數內。3．參考詞匯：收入--income
Dear editor,
I'm writing to tell you about the discussion we recently had about whether we should know our parents' income.
Suggested answer
Dear editor,
I’m writing to tell you about the discussion we recently had about whether we should know our parents’ income.
We do have different opinions on this matter. Most of us (about 70%) think we should know our parents’ income since it will help us understand how hard our parents have to work, no matter how much they earn. Then we will study harder and will not waste money any more. We may also learn to share our parents’ trouble.
About 30% of my classmates think it unnecessary to let the children know how much their parents earn. If they know their parents have enough money to support the family, they will not study hard since they needn’t worry about the future. It is said, especially when their parents have a higher income, the children will easily form a wasteful habit.
