四个例子解读托福阅读句子插入题

　　Eg1

　　Paragraph 1: Extinct but already fully marine cetaceans are known from thefossil record.

　　How was the gap between a walking mammal and a swimming whale bridged?

　　Missing until recently were fossils clearly intermediate, or transitional,between land mammals and cetaceans.Very exciting discoveries have finallyallowed scientists to reconstruct the most likely origins of cetaceans. In 1979,a team looking for fossils in northern Pakistan found what proved to be theoldest fossil whale.

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

　　This is a question that has puzzled scientists for ages.

　　Where would the sentence best fit?

　　我要你们铭记这道题，因为这道题无耻到了极致，指示代词this+名词，是第二种常规思路，找question的同意概念，有同学看完了四个空，说怎么没有问题的同意概念啊??!!再好好看看，第二个空之前那么明显的问号在那里!直接选第二个!对，就这么无耻

　　Eg2

　　Paragraph 7:The raising of livestock is a major economic activity insemiarid lands, where grasses are generally the dominant type of naturalvegetation. The consequences of an excessive number of livestock grazing in anarea are the reduction of the vegetation cover and the trampling andpulverization of the soil. This is usually followed by the drying of the soiland accelerated erosion.

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

　　This economic reliance on livestock in certain regions makes large tractsof land susceptible to overgrazing.

　　Where would the sentence best fit?

　　还是

　　指示代词this+名词，去前面找economic reliance onlivestock的同意概念，先运用无耻技巧1排除第一个空，然后看第二个空之前也就是第一句，有livestock is a major economicactivity，直接选第二个。

　　Eg3

　　Paragraph 6: Because they are always swimming, tunas simply have to opentheir mouths and water is forced in and over their gills. Accordingly, they havelost most of the muscles that other fishes use to suck in water and push it pastthe gills. In fact, tunas must swim to breathe. They must also keep swimming tokeep from sinking, since most have largely or completely lost the swim bladder,the gas-filled sac that helps most other fish remain buoyant.

　　11. Look at the four squares [l that indicate where the following sentencecan be added to the passage.

　　Consequently, tunas do not need to suck in water.

　　Where would the sentence best fit?

　　先看待插入的句子，Consequently，常规思路3，按照逻辑词的逻辑关系，先排除第一个空。看到第一句有because，认为第二个空可能对。再往后看，有同学说第二，第四空之后都有they，排除了选第三个。这就是我刚才提醒过的，当一段只有一个主语，或者说每句的主语都有一个词的时候，这种用其后后代词的排除法就失效了。看这段，每句的主语都是tunas，所以说，不能用代词排除了。

　　回到刚才的常规解法，运用逻辑关系，选择第二空!带入翻译一下，因为金枪鱼的经常游动，它们必须张着嘴使水流经它们的腮。因此，它们不需要吸水!

　　Eg4

　　Paragraph 6: Under very cold conditions, rocks can be shattered by ice andfrost. Glaciers may form in permanently cold areas, and these slowly movingmasses of ice cut out valleys, carrying with them huge quantities of eroded rockdebris. In dry areas the wind is the principal agent of erosion. It carries fineparticles of sand, which bombard exposed rock surfaces, thereby wearing theminto yet more sand. Even living things contribute to the formation oflandscapes. Tree roots force their way into cracks in rocks and, in so doing,speed their splitting. In contrast, the roots of grasses and other small plantsmay help to hold loose soil fragments together, thereby helping to preventerosion by the wind.

　　11. Look at the four squares [] that indicate where the following sentencecould be added to the passage.

　　Under different climatic conditions, another type of destructive forcecontributes to erosion.

　　Where would the sentence best fit?

　　看句子，another type，常规思路四，在空后寻找type of destructive force contributes toerosion. 的同意概念，第一个空，the wind is the principal agent of erosion.就是。如果你不放心，往下看看吧，第二个，有it，无耻技巧二有代词者排除，第三个even，甚至，不符合逻辑。第四个，有their，代词，排除掉。

　　这类题就告一段落了，提醒一下大家，因为无论用常规思路和无耻技巧都是一种快速的手段，用这些方法的时候你都没怎么好好读句子，所以，选出来之后，一定要回头读一读，是否通顺。
