一是看逻辑信号词;二是读句子的时候一定牢记只看主干。那么，在以下内容中我们就用一些实例为大家详细分析在托福阅读中如何准确找到关键字。
托福考试阅读部分一篇文章一般较长，所以一般是以段落为单位的。有时候可能会有学生说我做题的时候并不会去看整段啊，或者有学生说我看懂了哎，但题目就是没做对啊!其实我们在阅读一个段落时要学会使用方法，是什么方法可以帮助我们快速阅读呢?这就是我们今天给大家讲的内容了，如何巧抓关键词解决托福阅读题目。
下面我们就以托福TPO25中的文章The Decline of Venetian Shipping为例，说说如何巧抓关键词。
TPO25-2 The Decline of Venetian Shipping：
Paragraph 2 This decline can be seen clearly in the changes that affected Venetian shipping and trade. First， Venic’s intermediary functions in the Adriatic Sea， where it had dominated the business of shipping for other parties， were lost to direct trading. In the fifteenth century there was little problem recruiting sailors to row the galleys (large ships propelled by oars)： guilds (business associations) were required to provide rowers， and through a draft system free citizens served compulsorily when called for. In the early sixteenth century the shortage of rowers was not serious because the demand for galleys was limited by a move to round ships (round-hulled ships with more cargo space)， with required fewer rowers. But the shortage of crews proved to be a greater and greater problem， despite continuous appeal to Venic’s tradition of maritime greatness. Even though sailors’ wages doubled among the northern Italian cities from 1550 to 1590， this did not elicit an increased supply.
以上算得上是托福阅读中较长的段落了，在快速阅读这个段落的时候我们要找的关键词是：逻辑信号词—如段落中所标示的first， but， this… 我们不难发现这些信号词所在的句子基本都是解题的信息点。那么在做题定位时不妨多加留意。当然，抓住这些关键词并不难，难在理解。
接下来我们就来看看理解这些句子时的关键词。每段话的首句是必定要读的。This decline can be seen clearly in the changes that affected Venetian shipping and trade。这是包含了一个定语从句的复杂句。先看到核心词changes，再看到Venetian shipping and trade。这篇文章接下来具体要写的内容就展露无遗，也就是威尼斯船业和贸易的变迁。
First，这当然是开始写shipping的标志了。Venice’s intermediary functions in the Adriatic Sea， where it had dominated the business of shipping for other parties， were lost to direct trading. 我们一直强调句子要读主干，那么简单地看这个句子就是Venice’s functions were lost， 核心词很显然是lost，也对应了整篇文章的主题 decline. 接下来两句写到了15和16世纪遇到的船员难招的问题。…there was little problem recruiting sailors to row the galleys (large ships propelled by oars)： guilds (business associations) were required to provide rowers， and through a draft system free citizens served compulsorily when called for. 这句话中有冒号的出现，阅读冒号之前的内容there was little problem;到下一句：the shortage of rowers was not serious because the demand for galleys was limited by a move to round ships (round-hulled ships with more cargo space)， with required fewer rowers. 这句中要看到的核心是not serious;再往后看到But….to be a greater and greater problem. 到这里意思应该已经一目了然了，就是讲威尼斯船业在招聘船员方面所遭遇的变迁：little problem—not serious —greater problem.
