标题归纳题

★试题特点

标题归纳题考查考生准确理解全文、提炼信息、概括总结的能力。

标题归纳题实质上与全文大意题一样，考查的都是文章的主旨大意，只不过这两类题型的选项形式不同：前者通常是短语或短句，后者通常以一句话的形式出现。所以，解答标题归纳题的部分技巧对于全文大意题同样适用。

★解题思路

Step 1：读文章，寻找体现文章主线的信息句(□中句)

Step 2：归纳标题，全盘考虑——文章第一段开头作者就点明every summer，谈到了每年暑假旅行时喜欢读名著。第二段谈到今年夏天读书的困惑，第三段再次把读书和鸡尾酒联系，谈自己读书的感受。

Step 3：尝试解答——全文都和夏天读书有关，The Books of Summer适合作为标题，故选A。

One day when I was 12，my mother gave me an order：I was to walk to the public library，and borrow at least one book for the summer.This was one more weapon for her to defeat my strange problem—inability to read.

In the library，I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random.The cover of a book caught my eye.It presented a picture of a beagle.I had recently had a beagle，the first and only animal companion I ever had as a child.He was my secret sharer，but one morning，he was gone，given away to someone who had the space and the money to care for him.I never forgot my beagle.

There on the book's cover was a beagle which looked identical (相同的)to my dog.I ran my fingers over the picture of the dog on the cover.My eyes ran across the title，Amos，the Beagle with a Plan. Unknowingly，I had read the title.Without opening the book，I borrowed it from the library for the summer.

Under the shade of a bush，I started to read about Amos.I read very，very slowly with difficulty.Though pages were turned slowly，I got the main idea of the story about a dog who，like mine，had been separated from his family and who finally found his way back home.That dog was my dog，and I was the little boy in the book.At the end of the story，my mind continued the final scene of reunion，on and on，until my own lost dog and I were，in my mind，running together.

My mother's call returned me to the real world.I suddenly realized something：I had read a book，and I had loved reading that book.Everyone knew I could not read.But I had read it.Books could be incredibly wonderful and I was going to read them.

I never told my mother about my “miraculous” (奇迹般的) experience that summer，but she saw a slow but remarkable improvement in my classroom performance during the next year.And years later，she was proud that her son had read thousands of books，was awarded a PhD in literature，and authored his own books，articles，poetry and fiction.The power of the words has held.

Which one could be the best title of the passage?

A．The Charm of a Book

B．Mum's Strict Order

C．Reunion with My Beagle

D．My Passion for Reading

A　[通读全文可知，作者最开始有阅读障碍，在图书馆无意中看到了一本书，于是奇迹出现了，他不仅获得了博士学位，而且成为了一名成功的作家，故A项正确。]

B

Angel Garcia Crespo is a computer engineer at Carlos Ⅲ University of Madrid in Spain.His group has invented a new way for deaf­blind people to “watch” TV.The idea for the technology grew out of previous work by his group.The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities.But the group wanted to help people with both challenges.So they asked some deaf­blind people what would help.

In addition to relying on their sense of touch to communicate，deaf­blind people can also get and send information with a Braille line.The Braille system uses patterns of raised dots to stand for letters and numbers.A Braille line is an electronic machine with a changeable Braille display.Dots rise up or drop down based on the information sent to the machine.

Now the new system changes TV signals to data a Braille line can use.“The key to the system is the possibility of using subtitles(字幕) to collect TV information，” Garcia Crespo explains.“Subtitles travel with the image(影像) and the audio in electromagnetic waves we don't see.But an electronic system can keep those waves.”

First，a computer program，or app，pulls out the subtitles and visual descriptions from the broadcast signal.The system then combines the information and changes both into data for Braille.

Now another app gets to work，which sends the data out to people's Braille lines on demand.“This is done in real time，in less than a second，” Garcia Crespo says.This lets a deaf­blind person “watch” TV as it's broadcast.The system will work with various Braille lines，as long as there's a bluetooth connection available.Now，the system is only used in Europe，and it should soon be available in the US.

What should be a suitable title for the text?

A．New Technology Is Improving Deaf­blind People's Life

B．A New Braille Line Is Applied to Disabled People's Life

C．A Spanish Group Makes TV Accessible to Blind People

D．New Technology Helps Deaf­blind People “Watch” TV

D　[根据最后一段中“This lets a deaf­blind person ‘watch’ TV as it's broadcast.The system will work with various Braille lines，as long as there's a bluetooth connection available.”(这让聋哑人在电视播出时“观看”电视。只要有蓝牙连接，该系统可以使用各种盲文线路。)可知，文章最佳主题是“新技术帮助聋哑人士”看“电视”。故选D。]
