大家好，我是SK2实力养成班顾问，J2. 还没看过part 1的同学，记得先看过喔： https://webptt.com/cn.aspx?n=bbs/TOEFL_iBT/M.1547542082.A.26C.html 今天来继续分享一下插入句的作法，但着重在其中一个步骤，在想前後句的 时候，尽量具体一点。因为发现同学看过part 1後，顾问时间来问插入句， 都会有「想的不够具体」的问题。 举这个题目为例： This is a consequence of the slow rate of movement of the groundwater, which often prevents the water table from attaining a flat (horizontal) level. 步骤一：先彻底完整理解、消化这句话。 这句话是说「这是一个地下水的缓慢移动的结果，且通常使的地下水位无法 形成水平水位」。（简易翻译一下，如果有错或有相关专业的同学欢迎指 正:)） 步骤二：具体的想一下前後句会放什麽资讯。 问同学A前面会放什麽，同学可能就只有回答slow rate of movement. 这样想太笼统了，应该要再具体一点。前面要讲的应该是地下水缓满移动造 成的「一个结果」，我当场帮同学想到的是水可能滞留、流不出去等等。注 意作这件事情的目的不是要猜对，主要是要培养同学「主动思考」的能力。 猜错也无所谓，可以的话，尽量多想个几个。 步骤三：想完之後，就可以看原本的四个选项了。 In some cases, the water table reaches Earth's surface, where it is expressed as rivers, lakes, and marshes.■ Typically, though, the water table may be tens or hundreds of meters below the surface.■ The water table is not flat but usually follows the contours of the topography, the shape of a surface such as Earth's, including the rise and fall of such features as mountains and valleys.■ Above the water table is the vadose zone, through which rainwater percolates.■ Water in the vadose zone drains down to the water table, leaving behind a thin coating of water on mineral grains. 可以看到C选项的前面这句：The water table is not flat but usually follows the contours of the topography, the shape of a surface such as Earth's, including the rise and fall of such features as mountains and valleys . 水位不是平的而是通常跟着地形轮廓走…。是不 是就是原插入句的这是一个地下水的缓慢移动的「结果」呢？就算跟我一开 始猜的水可能滞留、流不出去天差地远，但也无所谓，因为有先主动思考 过，就比较能抓到句子之间的逻辑以及关联性。 再加码一题吧！ As a result, there are not enough of the strong competitors to monopolize the environment’s resources. 这题一样先请同学试试看步骤一：彻底了解句意＆步骤二：具体的想一下前 後句会放什麽资讯。 很显然的，前面的句子是要接没有足够的强势竞争者独占环境资源的「原 因」是什麽。 可能的想法有： 1) 有天敌 2) 食物多样性多、大家不用抢 3) 这里生态很平衡 看原本段落： Without predators, the species that is the best competitor for food, shelter, nesting sites, and other environmental resources tends to dominate and exclude the species with which it competes.■ This phenomenon is known as "competitor exclusion.■ " However, if the community contains a predator of the strongest competitor species, then the population of that competitor is controlled.■ Thus even the less competitive species are able to survive. ■ For example, sea stars prey on a variety of bivalve mollusks and prevent these bivalves from monopolizing habitats on the sea floor. 从文章应该可以判断出来，比较有像 “there are not enough of the strong competitors to monopolize the environment’s resources”的 原因的，应该只有CD这两个选项，AB可以直接删除掉。同学选到这里想必一 定会在C跟D之间犹豫很久，但一定有一个是比较好的答案。 C後面又有一句Thus even the less competitive species are able to survive. 所以简单来说，我们再来看以下两句话哪一个因果关系比较合 理： 1) As a result, there are not enough of the strong competitors to monopolize the environment’s resources. → Thus even the less competitive species are able to survive. 2) Thus even the less competitive species are able to survive. → As a result, there are not enough of the strong competitors to monopolize the environment’s resources. 再仔细思考一下，是不是会觉得1)「没有足够的强势竞争者，所以即使比较 不强势的物种也能存活」比较合理呢？所以C是更好的答案。 依照以上方法，长久练习下来，插入句除了把握度可以提高，还能越作越 快！ p.s. 请注意以上方法指的是平常练习的时候，考试的时候因为时间的关 系，当然就可以跳过这些步骤，赶快把四个选项都看过选一个吧！ Cheers, J2 --
