4、主旨题的信号标志词

　　Lecture引导主旨题信号标志词总结

　　1) 总结口语词后的动词词组：

　　­ today we will talk about.。.

　　­ today we will discuss.。.

　　­ today we will look at.。.

　　­ today we will tell.。.

　　2) 旧托福：

　　­ today we will spend several minutes in.。.

　　­ today we will focus on.。.

　　­ today we will concentrate on.。.

　　3) 动词时态

　　­ 've, -ed

　　­ will, be going to

　　4) 介词 ：

　　­ about

　　注意点：在第三条中，动词过去式和过去分词后面引导的都是上节课涉及到的内容，所以即使大家听到了discuss这个词也可以放弃这部分内容。而只要听好并把握准today后面要讲的内容即可，也就是be going to/will 后面引导的内容!那么，about就是一个经常引导主要内容的一个介词。这个词很关键，要求听准其后面的宾语是什么!因为这个宾语就是解题的关键。

　　Conversation 引导主旨题信号标志词总结

　　1. wonder (e.g. I was wondering,…)

　　2. think (e.g. I am thinking, I was thinking,…。)

　　3. hope (I was hoping,…)

　　4. need (Do you need, I need…。)

　　5. figure out, work out, sort out,

　　conversation的主要内容，一般情况下都是以上的这些词引导的。常用句型已在后面括号中标注出来。请同学们谨记在心。

　　5、主旨题的选项特征

　　在选择选项的时候，大家一定要避免选择如下选项：1) 范围小-细节进入主旨题(最常见);2) 范围大-没锁定主旨;3)不正确选项(即文章中根本没有涉及到的内容)

　　正确选项特征如下：( 以下是比较典型的主旨题的选项特征 )

　　1)长的名词结构：(技巧：先定位比较of和that前面的词，在原文中找同意替换。之后确定of和that后面的宾语是否符合原文)

　　a) …of…。

　　b) …that…

　　e.g. Script

　　So, I wanted to discuss a few other terms here…actually, some, uh some ideas about how we manage our resources. Let’s talk about what that…what that means. If we take a resource like water…well,

　　Q: What is the talk mainly about­

　　A. A common method of managing water supply。

　　B. The formation of underground water systems。

　　C. Natural processes that renew water supplies。

　　D. Maintaining the purity of underground water system。

文章中的这句话 “I wanted to discuss a few other terms here…some ideas about”很明确的点出了文章的内容主旨。根据上面的讲解，我们很容易把握discuss和about这两个词!所以，about后面的“how we manage our resources”就是文章的主旨了!所以根据同义替换，我们可以将“how”这个词替换为A选项的method而且of 后面的宾语(managing water supply)也同原文内容(how we manage our resources)一致!正确答案为A.。

　　2). 以how, what, why开头

　　e.g. Script

　　…so the Earth’s surface is made up of these huge segments, these tectonic plates. And these plates move, right­ But how can, uh, motion of plates, do you think, influence climate on the Earth­ Again, all of you probably read this section in the book, I hope, but, uh, uh, how— how can just motion of the plates impact the climate­

　　Q: What is the main topic of the talk­

　　A. The differences in climate that occur in different countries。

　　B. How movement of the Earth’s plates can affect climate。

　　C. Why the ocean has less effect on climate than previously thought。

　　D. The history of the climate of the region where the college is located

　　这道题可以明显根据部分文章重复找出答案!重复句式为“But how can, uh, motion of plates, do you think, influence climate on the Earth­”去掉其中的插入语，我们可以提炼出“how can motion of plates influence climate on the Earth”。与这句话一致的是B选项!其中，可以找到原文与选项的同义替换是motion=movement、effect= impact/ influence。从这道题目可以看出：特殊疑问词也是主旨题正确选项的一大特征!

　　3) To do

　　e.g. Script (lecture)

　　Ok. Another ancient Greek philosopher we need to discuss is Aristotle– Aristotle’s ethical theory. What Aristotle’s theory is all about is this: he is trying to show you how to be happy—what true happiness is。

　　Q: What is the main purpose of the lecture­

　　A. To illustrate the importance of extrinsic values

　　B. To explain Aristotle’s views about the importance of teaching

　　C. To explain why people change what they value

　　D. To discuss Aristotle’s views about human happiness

　　“To do”结构在主旨题中出镜率很高，目的主旨的选项大部分以to do结构开头。那么，解题的宗旨就是比较动词do的形式和用词!如果原文中用到的动词与选项一致，同学可以首先定位此选项，再比较后面的宾语即可。 “Ok. Another ancient Greek philosopher we need to discuss is Aristotle– Aristotle’s ethical theory。”从原文中可以看到discuss这个词，那么这个词正好与D选项中的discuss相吻合，而其后的宾语“human happiness”也一致!所以答案无可厚非为D。若选项中 “do”的形式与原文不一致，那么我们需要做的就是同义替换。请看下面的例子：

　　e.g. Script (conversation)

　　­ S: I was hoping you could look over my note cards for my presentation…just to see what you think of it。

　　­ P: Okay, so refresh my memory: what’s your presentation about­

　　Q: Why does the student visit the professor­

　　A. To get some note cards for his presentation

　　B. To show her some examples of common errors in research

　　C. To review the notes for his presentation with her

　　D. To ask for help in finding a topic for his presentation。

　　在这篇文章中，引导conversation主旨题的标志词是I was hoping， 在其之后出现的动词关键词是look over。名词关键词为：note cards for my presentation。所以，与原文一致的选项应该找look over的同义替换，即review!所以应该选择C选项。
