2017《夺冠之路》高三一轮人教版英语（安徽专用）：方法技巧难点2　精品课件

　　难点(二)　容易“顾此失彼”的“main idea”型主旨大意题 如果考生缺乏对文章整体理解的能力，就不能正确把握文章的主旨大意，不能排除干扰项，便会造成误选。 What does the passage mainly discuss? A．The present and past times. B．Machinery and human beings. C．Imaginations and inventions.　 D．Modern technology and its influence. (2010·江西卷，D) Modern inventions have speeded up people’s lives amazingly.Motor­cars cover a hundred miles in little more than an hour，aircraft cross the world inside a day，while computers operate at lightning speed.Indeed，this love of speed seems never­ending.Every year motor­cars are produced which go even faster and each new computer boasts (吹嘘) of saving precious seconds in handling tasks. All this saves time，but at a price.When we lose or gain half a day in speeding across the world in an airplane，our bodies tell us so.We get the uncomfortable feeling known as jet­lag；our bodies feel that they have been left behind in another time zone.Again spending too long at computers results in painful wrists and fingers.Mobile phones also have their danger，according to some scientists；too mcuh use may transmit harmful radiation into our brains，a consequence we do not like to think about.

　　However，what do we do with the time we have saved？Certainly not relax，or so it seems.We are so accustomed to constant activity that we find it difficult to sit and do nothing，or even just one thing at a time.Perhaps the_days are long gone when we might listen quietly to a story on the radio，letting imagination take us into another world. There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle.No multi­tasking there；their lives went on at a much gentler pace，and in a familiar pattern.There is much that we might envy about a way of life like this.Yet before we do so，we must think of the hard tasks our ancestors faced：they farmed with bare hands，often lived close to hunger，and had to fashion tools from wood and stone.Modern machinery has freed people from that primitive existence. [语篇解读]　本文为议论文，作者讨论了现代科技对我们生活的影响。 1．The new products become more and more time­saving because________. A．our love of speed seems never­ending B．time is limited C．the prices are increasingly high D．the manufacturers boast a lot 解析：　事实细节题。根据第一段第三句“确实，这种对速度的爱似乎永无止境”。 答案：　A

　　2．What does “the days” in Paragraph 3 refer to? A．Imaginary life.B．Simple life in the past. C．Times of inventions.D．Time for constant activity. 解析：　猜测词义题。答案在画线词的后半句“那时候我们可以安静地听着广播里的故事，让想象带我们到另一个世界去遨游”。所以那些天指的是过去简单的生活。 答案：　B 3．What is the author’s attitude towards the modern technology? A．Critical.　

　　B．Objective. C．Optimistic.D．Negative. 解析：　推理判断题。从全文最后两句可得知作者的观点“然而这样做之前，我们必须想想我们的祖先所面临的艰难工作：他们徒手耕作，经常生活在饥饿的边缘，不得不把木头和石头当做工具。现代机器已经把人们从原始的生存状态中解放出来了”。 答案：　B 4．What does the passage mainly discuss? A．The present and past times. B．Machinery and human beings. C．Imaginations and inventions. D．Modern technology and its influence. 解析：　主旨大意题。本文主题应包含现代科技和它造成的影响，故选D。A、C不相关；B.机械与人类，内容范围太广。 答案：　D 【长难句】　Perhaps the days are long gone when we might listen quietly to a story on the radio，letting imagination take us into another world.也许那些日子已离我们远去了，那时候我们可以安静地听着广播里的故事，让想象带我们到另一个世界去遨游。 此句是定语从句，先行词为the days，从句为when引导的句子。从句中又包含了非谓语作状语。

　　[化难为易]　“main idea”型主旨大意题也属于阅读理解中的深层理解题。这种题型中的干扰项通常和文章某一细节有关，许多考生往往只根据文中的某一信息盲目确定答案，比如文中介绍了现代科技对我们生活的影响，只有D项可以概括文章的主题思想。

　　主旨大意题要求考生要善于抓取文章的主题句，主题句通常表达了文章的中心思想(main idea)，找到了主题句，也就抓住了文章的主旨大意。因此，“主题句定位法”是解答主旨大意题的一种行之有效的方法。主题句通常在文章的开头或结尾出现，但是也有一些文章的中心思想贯穿全文，并没有用一句话明确表达出来，这就要求考生抓住文章中的关键词进行归纳概括。
