托福听力考试中如何记笔记一直是许多考生Z头疼的地方。有的考生搞不清笔记的重点在哪里,稀里呼噜一通记,要考的内容没记下来,记下来的内容都不考。而有的考生把每句话中的关键词都一一记下来,搞得自己疲惫不堪。其实,托福听力的考题大部分都是围绕语段的主旨句展开的。话句话说,只要能识别各个语段的主旨句,即可轻松地应对托福听力题目。下面托福培训机构培顿教育就和大家说说这方面的内容。
1、语段的三要素
大部分的语段都是由三个部分组成的:主旨句、扩展句和结尾句
主旨句用来点出语段的主题思想。扩展句围绕主旨句展开,用来说明、支持和阐述主题思想。结尾句用来得出结论,给读者留下深刻的印象。下面来看一个托福真题中的例子:
New computing, on the other hand, refers to an approach to design that focuses on the end goal, or more specifically the end-user’s goal; what the individual might need or want out of the computer. It places human beings front and center. In new computing the focus shifts from what computers can do to what people can do with computers. So instead of thinking about big power for the sake of having a fancy impressive machine, developers concentrate on individuals or specific groups of individuals. For example, they create products that support human activities, activities like collecting information or communication or disseminating information to others. I think Da Vinci would be very surprised about how well-informed people are about medical issues today when they arrive at their doctor’s office.
语段分析
该语段的第一句话是主旨句,新的计算机设计将用户的目标用途作为中心。后面的句子是扩展句,进一步解释计算机程序设计尊重客户的需求,而不再仅仅局限于计算机技术本身的发展。紧接着使用举例论证,提到了帮助用户收集信息、交流信息和传播信息的计算机产品,并提出达芬奇一定会为普通人所掌握的医疗信息而感到惊叹不已。
2、主旨句的位置
语段主旨句的位置并不是固定的
主旨句一般情况下出现在段首,但也可以置于段中或段尾。下面托福培训培顿教育分别介绍一下这三种情况。
(1) 位于段首
Ok, so it’s really important to find out what people want, what’s useful to them, before we develop new technologies, which brings me to the next point about new computing: that designs should be not only useful, but also user-friendly. Besides usefulness, usability is important. The idea that computer programs, accessories, websites, really anything related to your computer should be easy to use. Sounds simple, I know. The term user-friendly has been around for years. The problem is we don’t always create things that are easy for users to use. Take websites: many of you have probably been on websites that were really confusing. You couldn’t find the information you were looking for or there was so much information on the site that you just gave up. Again, this is where thinking like Da Vinci can help. The goal is to solve problems, not create new ones. Those websites might be really easy for their designers to navigate, but they aren’t the ones who need to use the sites. So again, designers need to involve the users from the beginning to find out their expectations and what kind of tasks they want to perform.
(2) 位于段尾
And it only gets better! You see under each of the buildings, architects designed a broad, shallow basement space that’s kind of like a maze. Air, either from within the building or from the outside, is pulled into the basement space through air ducts and then forced to move slowly around concrete barriers. The air is sort of guided through the maze. Now these concrete barriers, they absorb heat from the air if the air is warm or if the air is cold, the cold is absorbed into the concrete, so it could be either way. Let’s say it’s hot air; hot waste air being pulled in from the computer rooms, say. Well, that air moves slowly back and forth around these barriers. In this particular situation then, the heat from the incoming air is transferred to the concrete, which then holds onto it, storing the heat until later when it’s slowly released throughout the building. That’s the concept of thermal mass in a nutshell.
(3) 位于段中
位于段中的主题句起承上启下的作用,这类主题句多起转折作用,一般由“but, however,
yet, anyhow, nevertheless”等词连接,用于引起下文。
The “meshing hypothesis” has influenced a lot of schools in the United States, which have spent a lot of money to determine how individual students prefer to learn and also to purchase materials for teaching the students by targeting their individual learning styles. But, is there any evidence to support the hypothesis? Well, teachers do tell lots of anecdotes, stories, about how their students learn best; but as for solid evidence from scientific studies… well, a recent journal article concludes it doesn’t amount to much. The article was written by four psychologists, who looked at the experimental research that has been done on the “meshing hypothesis”. They wanted to see how well students did when the learning style of each student was identified, and then all the students were randomly divided into classes where the teaching was based on one particular learning style or another. The only really valid proof of the “meshing hypothesis” they argued would be to give the same test to all the students at the end of the course and see whether students of the class that matched their learning style generally outperformed the students in the class that didn’t match the learning style. As it turned out sometimes performance matched up with students learning style and sometimes it didn’t.
3、利用语段主旨句进行答题

【答案解析】正确答案为C.
如上所述,该语段的主旨句为第一句话,即新的计算机设计注重客户需求,正好对应C选项:Old computing concentrates less on the needs of users. 传统的计算机设计不太注重客户需求。
真题2

【答案解析】正确答案为C.
该语段的主旨句是Z后两句。大意是空气中的热量被混凝土所吸收并储存起来,随后慢慢地将热量释放到建筑物内。正好对应C选项:The temperature of air drawn in from other locations 。
