托福閱讀句子簡(jiǎn)化題方法，托?？绝唫兌贾?，句子簡(jiǎn)化題考查是對(duì)高光句理解，不需要看上下文。所以，該題型需要理解的是「句內(nèi)邏輯」?！ ills were undoubtedly the main source of oxygen for these fish, but the lungs served as an auxiliary breathing device for gulping air when the water became oxygen depleted, such as during extended periods of drought.
前面提到了這句話出現(xiàn)了「句內(nèi)轉(zhuǎn)折」。大家都知道轉(zhuǎn)折后內(nèi)容最重要，但轉(zhuǎn)折后也有很多單詞，到底哪個(gè)單詞最重要呢？所以，一定要把轉(zhuǎn)折前后內(nèi)容都要看，找到前后對(duì)立詞組，這樣才能真正理解轉(zhuǎn)折意圖。在這里，轉(zhuǎn)折邏輯的重點(diǎn)就放在尋找反義詞組上。
這句話中，你有沒(méi)有找到Gill VS lungs ?main ?VS auxiliary 這兩組反義詞。除開(kāi)這幾個(gè)單詞外，其他詞都可以略讀。也就是說(shuō)，這句話在圍繞兩個(gè)不同器官主次性的對(duì)比討論。
選項(xiàng)排除也是有套路的，既然高光句為轉(zhuǎn)折邏輯，選項(xiàng)篩選中要特別留意表達(dá)轉(zhuǎn)折關(guān)系的選項(xiàng)。
A Because the lungs of these fish were able to provide only a small amount of oxygen, these fish obtained most of their oxygen through their gills during periods of drought.
Because表示因果邏輯，而原文中并沒(méi)有出現(xiàn)因果話題，且“only a small amount”和”most of their oxygen“均在原文未提～PASS！
B During periods of extended drought, these fish used their lungs to increase their intake of oxygen beyond the levels absorbed by the gills in normal times.
Increase 表示比較邏輯，但是原文中并沒(méi)有說(shuō)過(guò)增多，ETS爸爸抖了個(gè)機(jī)靈！不要上當(dāng)喲！
C Although these fish primarily used their gills to obtain oxygen, they used their lungs to obtain oxygen from the air when there was not enough in the water.
萬(wàn)眾矚目的although出現(xiàn)了，表示轉(zhuǎn)折邏輯。“雖然內(nèi)容“中primarily=main, 正好是在說(shuō)Gill VS lungs, 必須選它?。?！
D During periods of extended drought, the gills became an auxiliary breathing device and the lungs became the main source of oxygen for these fish.
And 表示并列關(guān)系，gill作為auxiliary獲取氧方式與原文意思相反，輕輕松松OUT！
學(xué)好了邏輯關(guān)系，長(zhǎng)句子一遍看懂不回讀，看選項(xiàng)也不需逐字逐句翻譯，超省勁！讀懂了邏輯關(guān)系，哪怕是變了花樣，你也能輕松搞定！
