托福阅读7天计划-Day 3 Insert a Sentence

为了帮助大家更好的备战托福考试，留学监理网的老师在这里给大家介绍托福的几个阅读提升的方法---托福阅读7天计划。

句子插入题是托福考试特有的题型。

这类问题最多在每篇文章后出现一次。

文章中会有4处缺少一个句子，考生需要将文末给出的句子填在最恰当的地方，确保文章完整通顺。

这种题型旨在考察学生对文章逻辑关系的理解，以及如何将上下文连接起来的能力。

Strategies to answer the questions：

首先要仔细阅读这一段话，理解文章意思。

然后再看一下空缺句子的前一句跟后一句是否连贯，是否缺少过渡句。

注意一些连接词，如表示时间关系的then, next, finally, etc.，表示因果关系的consequently, as a result, etc.，或表示转折关系的but, however等词

理解要插入的句子的意思，放到原文中不连贯的地方，再阅读，确保文章通顺流畅。

也可以将这句话放到其他三处，读一下是否通顺，逻辑关系是否清晰。

Example:

下面我们就来看一道例题：

Part of a passage: Their demise also resulted in the extinction of a half-dozen species of forest insects and the severe crippling of other animal populations such as the wild turkey: these all relied on the American Chestnut as a source of habitat and food. ■ Affected wildlife attempted to adapt to their disrupted environment by looking to other species of trees, such as the Acorn, and seed-bearing plants for food. ■ This placed great ecological pressure on those species, as none could equal the American Chestnut in its ability to provide a consistently abundant crop of nuts. ■ The problems the American Chestnut blight engendered thus show the ripple effects that can occur within any ecosystem when new elements are introduced in an unsound manner. ■

Question: Look at the four squares ■ that indicate where the following sentence could be added to the passage.

In fact, is it widely believed that the scope of its devastation far eclipses even that of the fungal disease, also accidentally introduced, that ravaged Dutch Elm trees across Europe and North America, from 1910 to 1928.

Where would it best fit?

正确的答案是应该把句子插入到第四个空格。

因为这句话是对前一句的扩展。句中” its devastation” 是指上一句中” American Chestnut blight”所造成的影响。一次这句话不能插入到第三个空格。如果将这句话插入到第一或第二个空格，就会干扰有关American Chestnut消亡对生态环境的影响的描述。

下面大家趁热打铁，再做一题吧。

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

Look at the four squares [ ■ ] that indicate where the following sentence could be added to the passage.

Consequently, tunas do not need to suck in water.

Where would the sentence best fit?

在这道题中，大家注意到有一个具有提示性的词：Consequently，那么这句话的前一句应该是tunas不需要吸水的原因，这样后面才能街上Consequently。这句话”they have lost most of the muscles that other fishes use to suck in water and push it past the gills”正是表示原因的一句话，因此应插入到第三个空。
