1. 獨句成段就是以一個句子構成自然段，這在現代文章中是很常見的。不少由一個句子構成自然段，從內容上看并不是必須獨立成段，而是作者有意為之的。即為了取得特殊效果而讓某些句子單獨成段。
2. 句子單獨成段答題技巧
抓住對應的關鍵詞句。沒有明確要求引用原文答題的，不能機械地照抄原文的句子。一般來說，答案中涉及到的一些關鍵詞語、句子就在原文中，我們應抓住這些重要的詞句，進行有效的提取、剪輯、概括、重組、歸納。 還有一些題目是以選擇題形式出現，所以我們要了解這類題錯誤選項設置的規律（如斷章取義、偷換概念、范圍不清、無中生有、強加因果、偶然必然已然未然有意混淆），把選項和原文中的相關語句進行一對一的比較，做出準確的判斷和選擇即可。
