难点所在。托福阅读有十大题型， 每种题型必有难点，这是我们需要跨越的鸿沟，只有搞定这些难点才能考个不错的成绩，今天给大家分享托福阅读插入题难点所在，看看托福阅读插入题都有哪些难点吧~希望同学们通过自己的努力搞定这些难点，拿到高分!
难点1.只知埋头刷题，不知题型本质。
刚备考的同学们以为多刷题就能做对题，殊不知是不清楚考查方向。由于句子放在哪个黑方块，只与黑方块上下句产生联系，因此把握好句间关系，做题事半功倍。句间关系一般通过代词，逻辑词和语义建立起来。英文在这方面和中文相似，当文章涉及到已知事物或事情，为了避免重复累赘，直接用代词，如"教室里有五个学生。这些学生都在背单词。"总结TP0插入题发现，黑体句经常出现的代词有it/they/this/he或者their/this/these+名词短语等。在理解黑体句过程中，遇到这些代词，可预测黑体句前面有具体指代对象。
例如TPO19R1Q13：
Paragraph 7: Although the ecosystem concept was very popular in the 1950s and 1960s, it is no longer the dominant paradigm. ■ Gleason's arguments against climax and biome are largely valid against ecosystems as well. ■ Furthermore, the number of interactions is so great that they are difficult to analyze, even with the help of large computers. Finally, younger ecologists have found ecological problems involving behavior and life-history adaptations more attractive than measuring physical constants. ■ Nevertheless, one still speaks of the ecosystem when referring to a local◇◇ociation of animals and plants, usually without paying much attention to the energy aspects. ■
Look at the four squares [■] that indicate where the following sentence could be added to the passage.
They may be more interested in researching, for example, the adaptations that some aquatic animals undergo to survive in dry desert environments.
Where would the sentence best fit?
Click on a square [■] to insert the sentence in the passage.
很多同学看到这个长黑体句，一下子懵了，忘记做题方法，随便选择了第二个方框。如果理解完黑体句，发现其◇◇现they，黑方块前面要出现they指代一群人，可以排除第一，二个黑方块，由于第三个黑方前面有younger ecologists，因此黑体句应该放在这个黑方块。
难点2.只预测黑体句前面内容，忘了预测后面内容。
掌握了句间关系后，做题效率明显提升，但中等难度题目除了要求我们预测黑体句前面内容，还有积极预测后面内容。黑体句放进去的黑方块要与上下句发生联系，也就是说黑体句最好能起承上启下的作用，因此做题要思前想后才能克服错题。
例如TPO20R2Q13：
Paragraph 1：The universal global warming at the end of the Ice Age had dramatic effects on temperate regions of Asia, Europe, and North America. Ice sheets retreated and sea levels rose. ■The climatic changes in southwestern Asia were more subtle, in that they involved shifts in mountain snow lines, rainfall patterns, and vegetation cover. ■However, these same cycles of change had momentous impacts on the sparse human populations of the region. ■At the end of the Ice Age, no more than a few thousand foragers lived along the eastern Mediterranean coast, in the Jordan and Euphrates valleys. Within 2,000 years, the human population of the region numbered in the tens of thousands, all as a result of village life and farming. ■Thanks to new environmental and archaeological discoveries, we now know something about this remarkable change in local life.
Look at the four squares [■] that indicate where the following sentence can be added to the passage.
One of the major effects was the rapid growth of the human population itself.
Where would the sentence best fit?
Click on a square [■] to insert the sentence in the passage.
根据指代用法，黑体句说到one of the major effects，可以预测前面出现表示影响的内容，便会发现第一，三个黑方块都可入选。做好此题，还需结合黑体句主要影响之一是人口快速增长，前面讲到黑体句的作用为承上启下，因此可大胆预测后面内容会讲人口快速增长相关事情。只有第三个黑方块后面提及冰河时期末期只有no more than a few thousand foragers，2000年来人口数量增加了tens of thousands，最后可选第三个黑方块。
难点3.只关注黑体句，忽略段落结构。
学会借助黑体句的句间关系预测前后文，能保证插入题得分，但要想对付难题，还需考虑段落结构。
例如TPO15R3Q13：
Paragraph1: Glaciers are slowly moving masses of ice that have accumulated on land in areas where more snowfalls during a year than melts. Snow falls as hexagonal crystals, but once on the ground, snow is soon transformed into a compacted mass of smaller, rounded grains. ■As the air space around them is lessened by compaction and melting, the grains become denser. ■With further melting, refreezing, and increased weight from newer snowfall above, the snow reaches a granular recrystallized stage intermediate between flakes and ice known as firn. ■With additional time, pressure, and refrozen meltwater from above, the small firn granules become larger, interlocked crystals of blue glacial ice. ■When the ice is thick enough, usually over 30 meters, the weight of the snow and firn will cause the ice crystals toward the bottom to become plastic and to flow outward or downward from the area of snow accumulation.
Look at the four squares [■] that indicate where the following sentence could be added to the passage.
Firn has the appearance of wet sugar, but it is almost as hard as ice.
Where would the sentence best fit?
Click on a square [■] to insert the sentence in the passage.
运用前面的技巧，同学们很快就能预测出黑体句前会提到firn相关事情，对于后面预测的点不明确，可先不预测，这样先排除第一，二个黑方块，剩下我们要考虑最后两个黑方块，然而正确答案是第三个黑方块。因为第四个黑方块前句提到"时间、压力不断增加，并且位于上方的融雪重新结冰，那些较小的积雪颗粒开始变大且与透明的blue glacial ice。"后句马上提及"当the ice足够厚，积雪的重量就会使底部的冰晶变得具有可塑性，会从有积雪的地方流入或者流出。"这两句之间通过指代连起来，黑体句不能放进来，否则会割裂两个句子的关系。
托福阅读插入题难点所在就是这些了，希望同学们在了解的同时也能找到解决方案，帮助你顺利通过托福考试!
