高考英语阅读理解 主旨大意题解题技巧

一、题型介绍:

一篇文章一般表达一个中心或主题。这个中心或主题通常用一个句子来概括,此句叫主题句,这类题主要考查读者把握全文内容或理解中心思想的能力,也包括分析归纳文章段落大意、重要情节、人物特征、写作特点的能力。一般说来说明文和议论文都有主题句,而且多位于文章的开头,有时也位于文章的中间或末尾。但有时不能直接在文章中直接找到主题句,在弄清段与段之间逻辑关系的基础上自己归纳总结。主题句必须能简洁明了地概括全文的主要内容,具有高度的综合性和概括性,文章或段落的其他句子都是对主题句的进一步的解释、说明、论证或拓展。

常见的主旨大意题的考查形式:

The text is mainly about ____.

The main idea/The general idea/The main purpose is ______.

What's the main point the writer is trying to make in the last paragraph?

What would be the best title /headline for the text?

This article mainly tells about the story of ____.

What is the topic of the text?

The subject discussed in this text is ____.

What does the second paragraph discuss?

The paragraph (passage) deals with _____.

What is mainly discussed in the text?

二、主旨大意题解题方法与步骤:

略读法是理解全文大意的快速而有效的方法,略读的关键是能抓住文章要点的前提下,以个人最快的速度阅读,主要目的是尽快获得足够的信息以便准确的回答问题,利用略读法去做阅读时,要特别注意首尾两段,要学会寻找文章段落的主题句,这是高效省事地抓住段落要点的捷径,同时也是准确理解文章大意的有效途径。在做题时要注意以下步骤:

1.先看问题,看是否有和主旨相关的题目,了解题目类别和提问方式。

2.再看文章首尾和各段开头,找出主题句或通过浏览全文,抓住关键字眼,把握主旨。

3.以掌握主旨为前提,处理推断作者语气或意图等其他深层次问题。

三、考题探究

PITTSBURGH – For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.

The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots ,he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.

Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn't know of one that could climb pipes.

The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick(操纵杆). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.

Built from lightweight materials, the robots are about the size of a human arm or smaller. They can sense which way is up, but are only as good as their human operators, Choset added.

Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.

“It just allows us to do something we've not been able to do before,” Stover said, “We needed them yesterday.”

He said sniffer dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged building.

Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.
