　　托福閱讀句子插入題怎么做？技巧二：句間邏輯分析法——當然并不是每個題目都像上面那種情況一樣善良，我們也會碰到有代詞但用不上或者壓根沒有代詞的情況。

　　這個時候也不要害怕，可以用上我們在修辭目的題中說過的老朋友——邏輯關系幫我們解題。

　　例題二：

　　Leatherbacks keep their body heat in three different ways. The first, and simplest, is size. The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape. An adult leatherback is twice the size of the biggest cheloniid sea turtles and will therefore take longer to cool off. Maintaining a high body temperature through sheer bulk is called gigantothermy. ■It works for elephants, for whales, and, perhaps, it worked for many of the larger dinosaurs. ■It apparently works, in a smaller way, for some other sea turtles. ■Large loggerhead and green turtles can maintain their body temperature at a degree or two above that of the surrounding water, and gigantothermy is probably the way they do it. ■Muscular activity helps, too, and an actively swimming green turtle may be 7°C (12.6°F) warmer than the waters it swims through.

　　12. Look at the four squares [■] that indicate where the following sentence could be added to the passage.

　　However, these animals have additional means of staying warm.

　　Where would the sentence best fit?

　　這道題看似可以用我們的老方法代詞來做，但操作起來就會發現these animals除了可以幫助我們排除掉第一個小方塊，其實不能直接幫助我們選出答案，因為后三個小方塊前面的句子里都有不同的動物。

　　這時候就要用上我們的新技巧，邏輯分析法。先翻譯新句子的意思：然而，這些動物有額外的保持溫暖的方法。這里的轉折關系however說明在這個新句子的前面是一種保溫方法，而在它之后可能會講另一種保溫方法。

　　根據這個線索，我們可以觀察到前面三個小方塊里重復出現了gigantothermy這一個方法，而第四個小方塊后面說到Muscular activity helps, too一個叫做Muscular activity的方法也能幫忙，那么第四個小方塊就是我們要找的答案。
