托福閱讀插入句需要根據情景和句子類型來分析，不是所有的插入句都需要仔細研讀，也不是所有插入句都無關主旨。下面具體介紹一下如何解讀托福閱讀中的插入句，并以托福閱讀真題為例，介紹一下此類托福閱讀題型怎么解答。
　　掌握銜接詞是解答插入句子題的關鍵
　　掌握銜接詞對解答這類問題非常重要，因為它是理解上下文和這個句子的邏輯關系的核心。銜接詞語主要包括代詞(指示代詞，例如this, these their, it, such, another ，這些通常是上文提到過的，所以可以采用就近原則來做。);關鍵同義詞，重復出現的形容詞，副詞和名詞;表示因果，轉折等關系的過渡詞語：如，therefore, so, however, as a result, consequently, on the contrary, however 等;遞進擴展詞：如，furthermore, also, as well, too, in addition, moreover, besides, even, additionally等;結構配對詞：如，on the one hand…. on the other hand，some…others，同時還要注意一些表示順序的詞，如first ,second ,third等。
　　我們來具體來一個例子：
　　1. But there is also another special kind of conversational flow among Southern women that contributed to their writing. 2. Some of their talk took the form of tales and vignettes told for their own sake.3. Sometimes humorous, sometimes sad; all were as bright as the figures in the fine needlepoint. 4.
　　Look at the four positions that indicate where the following sentences can be added to the …paragraph of the passage.
　　These tales included grotesque, comic, and poetic descriptions, character sketches, narratives, gusts of feeling, delicate ironies, and astute observations.
　　Click on a position to add the sentence to the passage.
　　A: position 1 B: Position 2 C: Position 3 D: Position 4
　　具體的解題步驟：
　　1. 理解要插入的句子：These tales included grotesque, comic, and poetic descriptions, character sketches, and narratives, gusts of feeling, delicate ironies, and astute observations. 我們看這個句子是主、謂、賓結構，其中賓語為一些列的并列名詞和短語。
　　2. 尋找銜接詞：這個句子的銜接詞為：These tales
　　3. 分析這個句子和上下文的關系：位置1 不可能，因為它后面的句子是一個主題型句子，即，提出論點，而我們要插入的句子為一個小點，屬于論據。然后看位置2，這里出現了和我們要加入句子一樣的信息點Some of their talk took the form of tales and vignettes told for their own sake。顯然句子放在位置2是不行的;位置3后面的句子是對其前面句子for their own sake的進一步解釋。所以最后只能是位置4了。
　　4. 把這個句帶入各個位置。
　　5. 檢查每個位置，位置4是最恰當的。
