托福听力天文学场景分析

时间:2013-11-07 15:25来源:朗阁小编作者:allen

ETS的出题规律相信不少考生都已经摸的很清楚,但是新托福听力越来越难是一个趋势,很多初次参加考试的考生还是招架不来。比如听力的内容一多,速度一块,考生就接受不了。实际上托福是一个语言能力拓展的过程,考完之后才能过了起码的语言关。今天朗阁托福讲师给大家分析一下托福听力之天文学场景,希望大家能有所受用。

一、概述

 

天文学应该是许多考生头痛的话题。在教学过程中,南京朗阁托福老师发现,文科生觉得天文学较难,涉及物理学,比如开普勒定律;理科生虽然物理不错,但是往往缺乏基础知识,比如天狼星的叫法。天文学考察的频率在lecture中相对较高。可以从以下几个方面来考察:

 

1,宇宙:例如大爆炸理论,恒星与星云,星系,流星等

2,特定行星:例如木星,冥王星,天狼星,太阳,月球等

3,天文学理论:例如日心说与地心说,不同天文学家的观点,古希腊人对天文现象的解释等

4,其他话题:往往和其他学科有交叉,如历史等

 

首先,考生要对这些话题的中心词熟悉。在做TPO时一定要积累天文学词汇,做到会读和能够快速反应出意思。可以坚持每天听一个lecture, 记笔记找感觉。

 

二、案例分析

 

下面是一个天文学的经典案例:

TPO 21Part 2-Lecture 1 (Geocentric & Heliocentric theory)听力原文:

 

Professor: Ok, we have been talking about how throughout history, it was often difficult for people to give up ideas which have long been taken for granted as scientific truth, even if those ideas were false. In Astronomy, for example, the distinction between the solar system and the universe wasn’t clear until modern times. The ancient Greeks believed that what we called the solar system was in fact the entire universe, and that the universe was geocentric. Geocentric means Earth-centered, so the geocentric view holds that the Sun, the planets, and the stars, all revolve around the Earth, which is stationary. Of course, we now know that the planets, including Earth, revolve around the Sun, and that the solar system is only a tiny part of the universe.

 

So, whydid the ancient Greeks believe that the Earth was the center of the universe? Well, it made sense to them. Observations of the sky make it appear as if the Sun, the moon, and the stars all revolve around the Earth everyday, while the Earth itself stayed in one place. And this view is alsosupported by their philosophical and religious beliefs about the origin and structure of the universe. It was presented in the works of well-known Greek philosophers as early as the fourth century B.C.E., and the geocentric theory continue to prevail in Western thought for almost 2,000 years, until the 17th century.

 

分析:

这一段是描写古希腊人对地心说的信仰。这两段中划线部分为考点。朗阁海外考试研究中心的提醒广大考生,80%的段子前三句必出主旨题。因此,听到处划线部分,应马上记笔记(当然,这里有个小例外:考生会认为have been是迂回型主旨句,即在复习上节课的内容,重点在后面;但要注意have been talking是指一直在谈论的内容)。然后下文有一个重要概念的出现:geocentric。基础好的考生可根据词根词缀猜测,但若听不到也不要慌,因为段子中只要出现新概念,下文一定会解释。比如这里随后出现了earth-centered一词。

 

下文又出现两点原因。这当然是记笔记的重点,会考细节题。提醒考生,一个段子6分钟左右,不可能一直持精力高度集中。因此应该舍弃不该听的,比如文稿中出现的of course。这个表达对推动理论的发展没有什么作用,一般情况下可以略听。此外,重听的应该是文段中的黑体字,即同位,因果,递进。有所取舍,才能将段子题攻克。推荐笔记如下:

               

diff →弃ideas-古

eg. 天文

       geo-心

why?

1) 绕地

2) 哲+ 宗

 

 

三、考点追踪

 

从上面这个例子可以看出,天文类的听力话题具有以下特点:

 

1,生词。记笔记时用大写字母记下即可。只关注与主题有关的细节。知道这个词的含义并不重要,重要的是知道这个词与其他关键考点的联系和作用。

2,主题概念的引出。往往考察主旨题。

3,某种理论。比如上面例子中的地心说和日心说。一定要注意新词的解释,留心各种形式的同位语。

4,转折矛盾列举。由于篇幅有限,上例未将所有考点罗列出来。这个段子还考察了含有强转折的矛盾点,原文中用了problem一词;列举提到了一句话:Let me mention two objections.

 

作为南京托福培训行业的佼佼者,朗阁的老师提醒广大考生在备考中一定要用心尽全力去备考。托福听力考试一般情况下是不会考那种专业性特别强的话题,但也不排除会出现,考生在平时备考之外也要养成课外阅读的习惯,这样才能一句攻克托福听力。
