托福阅读句子简化题方法

　　托福阅读句子简化题方法，托福烤鸭们都知道，句子简化题考查是对高光句理解，不需要看上下文。所以，该题型需要理解的是「句内逻辑」。　　Gills 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.

　　前面提到了这句话出现了「句内转折」。大家都知道转折后内容最重要，但转折后也有很多单词，到底哪个单词最重要呢？所以，一定要把转折前后内容都要看，找到前后对立词组，这样才能真正理解转折意图。在这里，转折逻辑的重点就放在寻找反义词组上。

　　这句话中，你有没有找到Gill VS lungs ?main  VS auxiliary 这两组反义词。除开这几个单词外，其他词都可以略读。也就是说，这句话在围绕两个不同器官主次性的对比讨论。

　　选项排除也是有套路的，既然高光句为转折逻辑，选项筛选中要特别留意表达转折关系的选项。

　　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表示因果逻辑，而原文中并没有出现因果话题，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 表示比较逻辑，但是原文中并没有说过增多，ETS爸爸抖了个机灵！不要上当哟！

　　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.

　　万众瞩目的although出现了，表示转折逻辑。“虽然内容“中primarily=main, 正好是在说Gill VS lungs, 必须选它！！！

　　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 表示并列关系，gill作为auxiliary获取氧方式与原文意思相反，轻轻松松OUT！

　　学好了逻辑关系，长句子一遍看懂不回读，看选项也不需逐字逐句翻译，超省劲！读懂了逻辑关系，哪怕是变了花样，你也能轻松搞定！
