說(shuō)明利弊論說(shuō)是近幾年英語(yǔ)四六級(jí)常見(jiàn)的考題之一，它一般要求作者針對(duì)某一個(gè)事物或者現(xiàn)象從正反兩方面辯論它的優(yōu)缺點(diǎn)，然后表明作者自己對(duì)該事物或者現(xiàn)象的觀點(diǎn)和看法。這類題型一般可寫(xiě)成三段式文章。

第一段：抓住重點(diǎn)，直接了當(dāng)描述某一現(xiàn)象（事物）。
第二段：分別分析其優(yōu)點(diǎn)和缺點(diǎn)。
第三段：我的態(tài)度或看法。

參考模板：
　　Nowadays many people prefer A because it has a significant role in our daily life. Generally, its advantages can be seen as follows. First ----------------(A的優(yōu)點(diǎn)之一). Besides -------------------(A的優(yōu)點(diǎn)之二).
　　But every coin has two sides. The negative aspects are also apparent. One of the important disadvantages is that ----------------(A的第一個(gè)缺點(diǎn)).To make matters worse,------------------(A的第二個(gè)缺點(diǎn)).
　　Through the above analysis, I believe that the positive aspects overweigh the negative ones. Therefore, I would like to ---------------(我的看法).
　　(From the comparison between these positive and negative effects of A, we should take it reasonably and do it according to the circumstances we are in. Only by this way, ---------------(對(duì)前景的預(yù)測(cè)).)
