所謂三段式就是將一篇書面表達(dá)按三段的寫作模式謀篇布局。就整體篇章結(jié)構(gòu)而言，如何把握較大的寫作空間，三段式的寫作模式為最佳選擇。三段式的模式寫法通常為：

　　1.第一段開門見山，提出要解決的問題或觀點(diǎn)，或者把時間，地點(diǎn)，人物和主要事件及時點(diǎn)出。

　　2.第二段要擺出事實(shí)或提出論據(jù)，或者把事情發(fā)展的經(jīng)過詳細(xì)寫出來。

　　3.最后一段，得出結(jié)論或理由。

　　注意：要學(xué)會使用過渡詞。過渡詞猶如"橋梁"和"粘合劑 "。恰當(dāng)?shù)厥褂眠^渡詞可避免結(jié)構(gòu)松散，層次分明，表意不清等弊端，使文章條理清楚，文字連貫流暢。常用的過渡詞有：
