标题归纳题

记叙文、说明文和议论文三种文体涉及的不同话题的阅读材料都会考查到标题归纳题。设问形式常有：

(1)Which of the following can be the best title for the passage?

(2)What can be a suitable title for the passage/text?

(3)What is the best title for this passage?

(4)The most suitable title of this passage is        ．

一个好的标题应具备三大特点：概括——准确而又简短；针对性——标题外延正好与文章内容相符；醒目——能引发读者的阅读欲望。

解题技巧

1．“高度概括”定标题

(1)所选文章标题须能概括全文的中心内容。标题是文章的点睛之笔，是文章的灵魂和门面。为吸引读者的注意，标题往往比较醒目。

(2)一般文章的标题可根据主题句来判断，但在某些文章中，如记叙文，没有明确的主题句，需要根据文中的事实细节，查找文章的“主线”，归纳出文章的主题。

2．文章标题三特点

(1)形式一般为单词、短语或句子，其中短语居多；

(2)短小精悍，精确性强；

(3)涵盖性强，能覆盖全文大意。

[例文]

Steven Stein likes to follow garbage trucks.His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce litter，including things that fall off garbage trucks as they drive down the road.What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bags.

Americans use more than 100 billion thin film plastic bags every year.So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台)．The bags are prohibited in some 90 cities in California，including Los Angeles.Eyeing these headwinds，plastic­bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

Among the bag makers' arguments：many cities with bans still allow shoppers to purchase paper bags，which are easily recycled but require more energy to produce and transport.And while plastic bags may be ugly to look at，they represent a small percentage of all garbage on the ground today.

The industry has also taken aim at the product that has appeared as its replacement：reusable shopping bags.The stronger a reusable bag is，the longer its life and the more plastic­bag use it cancels out.However，longer­lasting reusable bags often require more energy to make.One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

Environmentalists don't dispute(质疑) these points.They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

★What is the best title for the text?

A．Plastic，Paper or Neither

B．Industry，Pollution and Environment

C．Recycle or Throw Away

D．Garbage Collection and Waste Control

A　[本文讲述了使用塑料袋造成的环境问题，纸袋容易回收，但生产和运输需要更多的能源，希望消费者使用耐用可重复使用的袋子。文章对这三个方面进行了对比，Plastic，Paper or Neither既能概括全文，又能吸引读者，适合作为标题，故选A。]

[即学即练]

If a city wants to hold the Olympics，it must submit a proposal to the IOC.After all proposals have been submitted，the IOC votes.If no city with the fewest votes is eliminated(淘汰)，the voting continues，until a majority winner is determined.Typically，the Games are awarded several years in advance，allowing the winning city time to prepare for the Games.

In selecting the site of the Olympic Games，the IOC considers a number of factors，and chiefly among them is which organizing committee seems most likely to stage the Games effectively.The IOC also considers which parts of the world have not yet hosted the Games.For instance，Tokyo，the host of the 1964 Summer Games，and Beijing，that of the 2008 Games，were chosen in part to popularize the Olympic movement in Asia.Because of the growing importance of television worldwide，the IOC in recent years has also taken into account the host city's time zone.Whenever the Games take place in the USA or Canada，for example，American television networks are willing to pay specially higher amounts for television rights because they can broadcast popular events live in the best viewing hours.

Once the Games have been awarded，it is the duty of the local organizing committee—not the IOC or the NOC of the host city's country to provide them with money.This is often done with a part of the Olympic television revenues(收入)，and corporate sponsorships，ticket sales，and other smaller revenue sources.In many cases there is also direct government support.Although many cities have gained amounts of money by hosting the Games，the Olympics can be financially risky.If the financial gains from the Games are less than expected，the city will be left with large debts.

★Which of the following can be the best title of this passage?

A．Winner or Loser

B．Applying for Host for the Olympics

C．How to Host the Olympic Games

D．The Olympic Games

B　[标题归纳题。通读全文可知，本文主要介绍了申办奥运会的流程：先向国际奥委会提交提案，国际奥委会根据规则和实际情况投票选择主办城市，一旦确定主办城市，则该城市应积极准备。故B项最适合作本文的标题。]
