主旨大意题

提分技巧：快速确定文章大意。没有明显的主题句的文章或段落要通过归纳要点抓大意。主题句位于文章或段落中间类型的文章要从段落中抓大意。主题句出现在开头的文章，如说明文、议论文、科技文献和新闻报道，要从首句中抓大意。段落中出现表示转折的词语(如however，but，in fact，on the contrary，in contrast等)时，其后的句子很可能是主题句。首段出现疑问句时，对该问题的回答很可能就是主题句。作者有意识地反复强调的观点，通常是主旨；反复出现的词语，一般为体现文章主旨的关键词。

[典例]　(2018·全国卷Ⅰ·阅读理解C节选)

Languages have been coming and going for thousands of years，but in recent times there has been less coming and a lot more going.When the world was still populated by hunter­gatherers，small，tightly knit (联系) groups developed their own patterns of speech independent of each other.Some language experts believe that 10，000 years ago，when the world had just five to ten million people，they spoke perhaps 12，000 languages between them.

Soon afterwards，many of those people started settling down to become farmers，and their languages too became more settled and fewer in number.In recent centuries，trade，industrialisation，the development of the nation­state and the spread of universal compulsory education，especially globalisation and better communications in the past few decades，all have caused many languages to disappear，and dominant languages such as English，Spanish and Chinese are increasingly taking over.

At present，the world has about 6，800 languages.The distribution of these languages is hugely uneven.The general rule is that mild zones have relatively few languages，often spoken by many people，while hot，wet zones have lots，often spoken by small numbers.Europe has only around 200 languages；the Americas about 1，000；Africa 2，400；and Asia and the Pacific perhaps 3，200，of which Papua New Guinea alone accounts for well over 800.The median number (中位数) of speakers is a mere 6，000，which means that half the world's languages are spoken by fewer people than that.

Already well over 400 of the total of 6，800 languages are close to extinction (消亡)，with only a few elderly speakers left.Pick，at random，Busuu in Cameroon (eight remaining speakers)，Chiapaneco in Mexico (150)，Lipan Apache in the United States (two or three) or Wadjigu in Australia (one，with a question­mark): none of these seems to have much chance of survival.

31．What is the main idea of the text?

A．New languages will be created.

B．People's lifestyles are reflected in languages.

C．Human development results in fewer languages.

D．Geography determines language evolution.

C　[第一段说明语言已有几千年的历史，但有一些语言正在消失；第二段说明随着人类社会的发展，语言变得更少；第三段说明语言的分布是不均匀的；第四段介绍了超过400种语言正面临消亡的威胁。整篇文章主要说明的是由于人类社会的发展导致了语言变得越来越少。故选C。]

(2017·浙江卷·阅读理解A节选)

Benjamin West，the father of American painting，showed his talent for art when he was only six years of age.But he did not know about brushes before a visitor told him he needed one.In those days，a brush was made from camel's hair.There were no camels nearby.Benjamin decided that cat hair would work instead.He cut some fur from the family cat to make a brush.

...

In 1747，when Benjamin was nine years old，Mr.Pennington returned for another visit.He was amazed at what Benjamin had done with his gift.He asked Benjamin's parents if he might take the boy back to Philadelphia for a visit.

In the city，Mr.Pennington gave Benjamin materials for creating oil paintings.The boy began a landscape (风景) painting.William Williams，a well­known painter，came to see him work.Williams was impressed with Benjamin and gave him two classic books on painting to take home.The books were long and dull.Benjamin could read only a little，having been a poor student.But he later said，“Those two books were my companions by day，and under my pillow at night.” While it is likely that he understood very little of the books，they were his introduction to classical paintings.The nine­year­old boy decided then that he would be an artist.

21．What is the text mainly about?

A．Benjamin's visit to Philadelphia.

B．Williams' influence on Benjamin.

C．The beginning of Benjamin's life as an artist.

D．The friendship between Benjamin and Pennington.

C　[根据第一段第一句“Benjamin West，the father of American painting，showed his talent for art when he was only six years of age.”以及选文第二段第一句“In 1747，when Benjamin was nine years old”和最后一段，并结合全文可知，本文主要讲述了艺术家本杰明·韦斯特少年时代的艺术启蒙。]
