托福聽力中,這類基本理解性問題分為2類:內(nèi)容主旨和目的主旨。
Identifying the main idea
在每段聽力開頭,都會有這樣一句話:Listen to part of a lecture from a chemistry class. 其中的chemistry就是重點詞,說明這篇文章的中心為chemistry。這樣大家在聽這篇文章之前就可以知道這篇文章主要講的是什么。
Some tips about identifying the main idea
1. 排除選項中描述具體細節(jié)的選項;
2. 注意聽文中重復率高的詞匯。Conversation或lecture中表達主旨的詞匯會經(jīng)常出現(xiàn),大家一定要認真聽。
Example:
Listen to part of a lecture from a chemistry class.
Professor: Ok, put away your lab coats please. Today we're going to cover a bit of history. Yes, yes, I know, this is a chemistry class, not a history class, but we'll be talking about the history of that most famous of chemical diagrams, the periodic table of elements. Open up your textbooks to page 143.
To understand where the table comes from, first we need to look back to when the Greek philosopher Aristotle proposed that everything is divided into four main elements: earth, fire, air, and water. Although it doesn't sound very scientific to us now, Aristotle was actually closer to describing the four states of matter than he was in pinpointing the elements. I mean... solid, liquid, gas, and plasma. Nevertheless, Aristotle's initial classification of matter into four main types laid the groundwork for future scientists to ultimately discover and understand the properties of all of the individual elements we know today. The discovery of elements was a gradual process, with many different scientists having a hand in the discoveries. For example, in 1669 and 1680, both Hennig Brand and Robert Boyle independently discovered phosphorus. In 1789, Antoine Lavoisier published his Treaty on the Chemical Elements, in which he defined for the first time what an element actually is, and included a list. The list continued to grow. As more and more elements were discovered, scientists around the world searched for a way to classify them.
Question: What is the main topic of discussion?
A. Chronological history of Victorian chemistry
B. The varied attempts at element classification
C. Mendeleev's life and ultimate achievements
D. Publication of chemistry works in the 1800's
這個lecture是按照時間順序講述的element classification的發(fā)展,并不是圍繞整個維多利亞時代的化學的發(fā)展展開的,因此A項不正確。Mendeleev只是創(chuàng)建元素周期表的人之一,整篇lecture并不是圍繞他展開的,C項也是錯誤的。這個lecture重點講的是元素的分類,并不是泛泛的談化學,D項不對。答案是B。
Identifying the purpose
目的題通常出現(xiàn)在對話中,因此大家要通過整段對話了解講話人的目的,而不是僅抓著細節(jié)不放。
目的題通常有兩種提問方式:
Why did the speaker say that?
What was the purpose of saying that?
Example:
Listen to a conversation between a student and a teacher.
Student: Hello Professor, I made an appointment to see you today at 3:00 p.m...?
Professor: Yes... Benjamin? You're right on time. Come in, have a seat. Are you here about next week's test?
Student: Yes, there's just one point that I'm still a little stuck on... and I was hoping I could go over it with you.
Professor: Of course... I always try to make time to help out students in your situation.
Student: Well, I've been reviewing the main economic concepts you discussed in class, but I'm still confused as to the difference between "foreign exchange rates" and
"Purchasing Power Parity." You know... PPP.
Professor: I see. Well, let's try to narrow down the area where you're lost.
Question: Why does the student go to see the professor?
A. To obtain a list of the main concepts covered in the lectures
B. To ask if a concept will appear on a test
C. To review a concept's main principles
D. To distinguish between two different concepts
文本中標出的部分是答題的關鍵。學生去拜訪教授是因為他不太清楚"foreign exchange rates"和"Purchasing Power Parity"的區(qū)別。
這兩類問題只要大家認真聽,都可以答對。大家可以通過做真題來鞏固一下。
以上就是小編為大家整理的托福聽力考前6天備考沖刺的計劃及內(nèi)容,大家臨近考試時不妨來借鑒一下,看看是否對你有幫助。同時你也可以根據(jù)這些設定自己的考前沖刺計劃,希望可以幫助到大家。最后,小編預祝大家托??荚嚹苋〉美硐氲某煽儭?/p>
