智课网TOEFL备考资料托福阅读插入题解题技巧 1、结构突破法。所谓结构突破法，第一步就是观察被插入句的特殊结构(如比较句、平行句等)，然后从目标句中挑选出与被插入句结构相似的句子，最后判断它们的先后顺序。请看下面的例题 Paragraph 2 Another task for the Glomar Challengers scientists was to try to determine the origin of the domelike masses buried deep beneath the Mediterranean seafloor. These structures had been detected years earlier by echo-sounding instruments, but they had never been penetrated in the course of drilling. Were they salt domes such as are common along the United States Gulf Coast, and if so, why should there have been so much solid crystalline salt beneath the floor of the Mediterranean? 12. Look at the four squares that indicate where the following sentence could be added to the passage. Thus, scientists had information about the shape of the domes but not about their chemical composition and origin. Where would the sentence best fit? 注意到被插入句是一个很对称的结构，but前面是个肯定句，后面是个否定句，而第二个方框后面的句子也是同样的结构，再结合被插入句的第一个单词 “thus”可知，被插入句应该插在第三个方框处。 2、关键词突破法。关键词包括代词、逻辑词等，根据这些关键词，我们可以快速地锁定要插入的位置。请看下面的例子 Paragraph 5: Not only could Smith identify rock strata by the fossils they contained, he could also see a pattern emerging: certain fossils always appear in more ancient sediments, while others begin to be seen as the strata become more recent. By following the fossils, Smith was able to put all the strata of Englands earth into relative temporal sequence. About the same time, Georges Cuvier made the same discovery while studying the rocks around Paris. Soon it was realized that this principle of faunal (animal) succession was valid not only in England or France but virtually everywhere. It was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna. Limestone may be found in the Cambrian or300 million years laterin the Jurassic strata, but a trilobitethe ubiquitous marine arthropod that had its birth in the Cambrianwill never be found in Jurassic strata, nor a dinosaur in the Cambrian. 13.Look at the four squares that indicate where the following sentence could be added to the passage The findings of these geologists inspired others to examine the rock and fossil records in different parts of the world. Where would the sentence best fit? 此题关键词是代词 “these geologists”，由此可知它的前面提到了一些地质学家，可考虑放在第三个方框处，代入后发现前后语义非常连贯。关键词突破法可以帮助我们节省很多时间，而且命中
