托福听力作为托福考试中最重要的部分之一，考得不仅仅是同学们的应变能力，更是同学们对美国文化的掌握程度，因此在备考托福的过程中，同学们需要积累一些美国历史类的托福词汇和文化背景，本文小编将为同学们带来托福听力中的关键历史类要素的内容，希望能够帮助正在备考托福的同学们!
一、主题关键词，总是会出现和发展、起源或者历史相关的词汇(e.g develpoment, change, origin, historical)
【Professor: And what instrument comes to mind when you think of rock ‘n' roll?
Student: The electric Guitar?
Professor: Exactly. I think it's fair to say that the sound of the electric guitar typifies the rock ‘n’ roll genre,which became popular in the 1950s. But really the instrument we know today was the result of a continuing development that started for our practical purposes in the 1920s. But long before that even,people were experimenting with ways to modify traditional acoustic guitars.】
注意到文章开头做了两件事情：一. 提出话题“ Electrical Guitar”; 二. 提出了历史类文章要素, 教授说到电吉他是一个“the result of a continuing development” 而且人们很早之前就开始“ modify acoustic guitar”，自然而然我们就能推测文章是要讲电吉他是如何发展起来的。
二、影响，其中包括话题的发展;发展过程中所受到的影响;其所产生的影响;具体的影响是什么，怎么影响的。
【The first guitars were wooden. This is the Spanish guitar and the strings were made from animal products. Then came steel strings. And that led to the lap guitar,which is also called the steel guitar because the player slides a steel rod up and down the neck. And those are all acoustic guitars. OK?
But then eventually we have electric guitars. Over the years,many inventors and musicians contributed to the design of these instruments. And each design was intended to alter the sound in some way,at first at least with the electric guitar,to make it louder.
以上就是小编为同学们整理的托福听力中的关键历史类要素的全部内容，希望能够帮助正在备战托福的同学们！
