托福阅读句子插入题怎么做？技巧二：句间逻辑分析法——当然并不是每个题目都像上面那种情况一样善良，我们也会碰到有代词但用不上或者压根没有代词的情况。

　　这个时候也不要害怕，可以用上我们在修辞目的题中说过的老朋友——逻辑关系帮我们解题。

　　例题二：

　　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?

　　这道题看似可以用我们的老方法代词来做，但操作起来就会发现these animals除了可以帮助我们排除掉第一个小方块，其实不能直接帮助我们选出答案，因为后三个小方块前面的句子里都有不同的动物。

　　这时候就要用上我们的新技巧，逻辑分析法。先翻译新句子的意思：然而，这些动物有额外的保持温暖的方法。这里的转折关系however说明在这个新句子的前面是一种保温方法，而在它之后可能会讲另一种保温方法。

　　根据这个线索，我们可以观察到前面三个小方块里重复出现了gigantothermy这一个方法，而第四个小方块后面说到Muscular activity helps, too一个叫做Muscular activity的方法也能帮忙，那么第四个小方块就是我们要找的答案。
