托福阅读之句子插入题分析系列之三

 大家好, 我是托福句子插入题探索小分队队长柳杉小姐姐, 我们继续句插探索之旅.

简短回顾一下, 上次我们总结出想解决这种题型必须找到待插入句子中的线索, 然后验证该句在原文中是否起到承上启下作用. 同时,也领略了第一类线索, 代词指代和逻辑关系. 那么,今天我们来探究第三类线索, 重复的核心词.

核心词是指待插入的句子和原文某句中有重复出现的原词, 原词通常是名词., 这个原词可以作为解题线索使用.

例子一

■【A】The climatic changes in southwestern Asia were more subtle, in that they involved shifts in mountain snow lines, rainfall patterns, and vegetation cover. ■【B】However, these same cycles of change had momentous impacts on the sparse human populations of the region. ■【C】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. ■【D】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.

待插入句子讨论了其中之一的影响就是人口的快速增长, 判断上下文应该和人口population有关系. 回原文阅读发现, A和population无关, B后出现了population, C的前后都有population, D选项讲论今天的人们和待插入句无关. 验证发现C选项的前研究对人口的影响,C后举例子来具体解释对人口的影响, 符合线索判断, 确定C就是答案.

重复的核心词除了可以帮我们正面找答案, 也可以辅助我们使用排除法. 来看上次的例子.

Paragraph 5: █Modern architectural forms generally have three separate components comparable to elements of the human body; a supporting skeleton or frame, an outer skin enclosing the interior spaces, and equipment, similar to the body’s vital organs and systems. █The equipment includes plumbing, electrical wiring, hot water, and air-conditioning. █Of course in early architecture—such as igloos and adobe structures—there was no such equipment, and the skeleton and skin were often one. █

13．Look at the four squares [█] that indicate where the following sentence could be added to the passage.(4)

However, some modern architectural designs, such as those using folded plates of concreter or air-inflated structures, are again unifying skeleton and skin.

Where would the sentence best fit?

上次讲解从however转折逻辑出发, 今天我们从重复的核心词角度来研究这个题目. B前句最后提到了equipment, 同时B后句主语也是equipment, 说明这2句话不可拆解也与待插入句子无关,因为插入句没有涉及equipment, 这么简单粗暴就可以判断答案是D. 所以, 解题的时候大家可以灵活使用这3种方法, 达到快准做题的目的.

到这里, 句子插入题的解题方法就和大家探索完毕, 我相信聪明的你已经get到倚天剑屠龙刀.小伙伴们, 在这个众志 成城抗击疫情的时刻, 我们在室内愉快学习为祖国做贡献吧.
