1、托福培訓(xùn)丨托福閱讀句子插入題解題要點(diǎn)朗閣托福培訓(xùn)中心孫亞楠句子插入題是托福閱讀中的一道必考題型，題量不多，每篇文章中出現(xiàn)一道。句子插入題是給出一句話讓我們來判斷這句話應(yīng)該加入1-2個(gè)段落中的四個(gè)黑方塊的哪個(gè)部分，用鼠標(biāo)點(diǎn)擊所選的黑色方塊即可。做這類題目的關(guān)鍵首先是理解待插入的句子，尋找其中的銜接詞，分析這個(gè)句子的特點(diǎn)和其在文中的作用，然后把這個(gè)句子帶入原文中檢驗(yàn)其是否合適。下面朗閣托福培訓(xùn)中心的專家將就句子插入題的解題步驟做出詳細(xì)的說明。解題步驟與解題要點(diǎn)?閱讀并分析待插入的句子，找出其中的線索詞；?從第一個(gè)小黑方塊前一句開

2、始讀，逐一代入進(jìn)行驗(yàn)證；?插入句必須滿足前后兩條線索，先前再后。（先用前線索再看后線索）從此步驟中可以看出掌握線索詞是解答此題的關(guān)鍵，那么線索詞都有哪些？主要有兩大類，指代線索和邏輯線索。1.指代線索(1).指代詞(they,it,them)必然有所指代；指代詞(this,these,their,other,another,such)后面若有名詞短語，則向前尋找此名詞短語或其同義改寫。例題1:Paragraph4:Regularlyflowingriversandstreamsthatoriginatewithinaridl

6、dedtothepassage.Thesesuddenfloodsprovideimportantwatersuppliesbutcanalsobehighlydestructive.Wherewouldthesentencebestfit?解析：1.分析黑體句，找到其中的線索詞即為thesesuddenfloods,則要插入的方塊前面必定要出現(xiàn)名詞短語suddenfloods或是其同義改寫。2.從第一個(gè)小黑方塊前一句開始讀，尋找與線索詞相吻合的信息。3.在第三個(gè)方塊前面出現(xiàn)了largeflowsofwaterandsedi

7、ment（巨大的水流和沉積物），即為suddenfloods的同義替換，所以答案應(yīng)當(dāng)是第三個(gè)黑方塊的位置。例題2:Paragraph4:Oneoftheouterplanets,Saturn,hasadensityofonly0.7thatofwater,whichmeansthatSaturnwouldfloatinwater.Variationsinthecompositionoftheplanetsarelargelyresponsibleforthedensitydifferences.■Thesubstancest
