英语阅读理解主旨大意题的解题技巧
高考英语阅读理解主要考查考生能够在单位时间内快速阅读英语短文，了解短文的主题思想，对文中信息进行分析、推理、判断，并把握上下文事实、细节之间的时空顺序和逻辑关系，理解作者的意图、态度以及文章寓意的能力。综观历年阅读理解题的设问，我们可以看出：试题设问手法灵活、提问深入，而且语篇意识进一步加强了；不仅要求学生理解文章的字面意思，还要求学生理解文章的内在含义。
阅读理解的考查题型主要有六大类：细节理解题，推理判断题，主旨大意题，词义猜测题，判断作者意图、态度、观点题和判断文章的基本结构题。其中，主旨大意题型旨在考察考生通过快速阅读获取语篇的中心思想的能力，以及辨别主要信息和次要信息的能力。要求考生运用逻辑概括能力，从文章的字里行间获取文章中的代表性观点和中心论点。主旨大意题是考生容易出错的题型之一，错误主要表现为：概括文章中心时以偏概全（只见树木不见森林），概括性不够，或者概括过度，超出了文本的内容，缺乏针对性。高考阅读理解主旨大意题型的命题形式主要有：
1. The main topic/subject of the passge is _____.
2. What is mainly discussed in the text/X paragraph？
3. What is the main idea of the passage？
4. The purpose of this passage is _____.
5. The passage mainly focused on _____.
6. What would be the best title/topic/headline of the text？
上述命题形式大致可以概括为三类：选择段落或文章的主题思想、写作目的和标题。下面结合高考实例来分析主旨大意题的解题技巧。
一、文章或者某段落的主旨大意——主题句定位法
众所周知，文章是由段落组成，每个段落都是围绕某个中心思想展开的一群句子的组合，而段落的中心思想又是为文章主旨服务的。寻找文章中心思想的方法是：通过分析篇章结构，找出每一小段的主题句，然后通过寻找共同点，找出整个文章的主题句，这是找准文章主题大意的关键。主题句是文章的核心，它往往是一个有很强概括性和代表性的句子。找到了文章的主题句，文章的中心思想也就显而易见了。但是由于文章表现手法各不相同，主题句出现的位置也不尽相同。在多数情况下，尤其在说明文和议论文中，主题句在文章中的位置通常有三种：开头、文中和文末。解题时，我们通常采用浏览的方式，仔细选读文章的首尾段和首尾句（包括每一段的首尾句），重点搜索主题线索和脉络。下面阐述五种主题呈现的方式：
1．开门见山式
主题句出现在文首。开门见山，提出主题，随之用细节来解释、论证或发展主题思想。这种写作手法叫做演绎法，在英语文章中尤为常见，这种文章的主题句最容易找到，故主题思想显而易见。
（2005年全国高考重庆卷E篇）：
In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity. Others say that competition is bad，that it sets one person against another; that it leads to unfriendly relationship between people.
①What does this passage mainly talk about？_________
petition helps to set up self-respect.
B.Opinions about competition are different among people.
petition is harmful to personal quality development.
D. Failures are necessary experience in competition.
2．藏头露尾式
主题句出现在文尾。即文章先阐述了细节，然后归纳要点，得出结论，概括主题，叫做归纳写作法，主题句往往位于末段。这一类文章的主题句也很明显，不难找到。
On the Internet, we can read news at home and abroad and get as much information as we can. We often send e-mails or make telephone calls to our families as well as to our friends by Internet. What’s more, we can go to school on the net, read a lot of books and even teach ourselves foreign languages. We also enjoy music, watch ball matches on the net and play computer games. With the help of the net, we can do shopping even without leaving our homes. The Internet is playing a more and more important part in our daily life.
②What’s the main idea of the passage？________
A. Keep away from the Internet.
B. Surf the net.
C. The Internet is playing an important part in our daily life.
D. We can entertain ourselves on the Internet.
3．首尾呼应式
在有些文章中，为了突出主题，作者在文章开头提出主题，接着进行阐述或论证，在结尾时再次点出主题，这种首尾呼应的写作方式也很常见。值得注意的是，前后两个主题句不是简单的重复，再次出现的主题句往往是前面主题句的进一步引申或发展。

③The passage is mainly about _________ .
A. How to Play Lacrosse
B. Lacrosse in Canada
C. The History of Lacrosse
D. Lacrosse—A Popular Game in Canada
4．抛砖引玉式
即文章的开头只是提出一个问题或者貌似正确的观点，而真正的主题则是通过对问题的解析和引申，或是通过责问和驳论的方式导出主题。
