主题句在首句

A quick reading of newspapers leads us to one conclusion. Actual events are never told us in full detail. Newspapers only tell enough to satisfy those who finance them. If the newspapers told us what was actually going on in the world, people would be so upset that they might retrain from reading the paper.

 

上述短文只有四句，却可以分为三个层次：第一句为第一层次，表示主题思想；第二句为第二层次，点出

"one conclusion"的具体内容；第三、四句是第三层次，在同一平面上为第二句提供理由，从属于第二句。

 

主题句在尾句

A few years ago it was fashionable to speak of a generation gap, a division between young people and their elders. Parents complained that children did not show them proper respect and obedience while children complained that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? Actually, the generation gap has been around for a long time. It is built into the fabric of our society.

The main idea of the paragraph is _ .

 

A. that the generation gap suddenly appeared

B. that the generation gap is a feature of the society

C. that parents and children could not understand each other

D. what the generation gap is

 

答案是B。A、C、D只是文中提到的各项具体内容，作为主题思想太狭窄了，只有B才概括了全段要说明

的内容。

 

首尾结合主题句

Good manners are important in all countries, but ways of expressing good manners are different from country to country. Americans e with knives and forks; Japanese eat with chopsticks. Americans say "Hi" when they meet; Japanese bow. Many American men open doors for women; Japanese men do not. On the surface, it appears that good manners in America are not good manners in Japan , and in a way this is true. But in any country，the only manners that are important are those involving one behavior toward another person. In all countries it is good manners to behave considerable toward others and manners not to. It is only the way of behaving politely that differs from country to country.

 

这段文章的首句和尾句都是主题句。这种重复既起了强调主题句内容的作用，又起了首尾呼应的作用

 

中间句主题句

There is a simple economic principle used to determine prices. It is called the law of supply and demand.Supply means the amount of, or access to, certain goods. Demand represents the number of people who want those goods . If there are more goods than wanted , the price of them falls . On the other hand , if the demand for these goods is much greater than the supply, then the price rises. Of course, manufactures prefer to sell more goods at increased prices.

 

The best title for this passage is     

 

A. Economic Principles

B. Law of Supply and Demand

C . More Goods , Low Prices

D. Fewer Goods, Higher Price

 

答案是B。A泛指经济规律，面太宽；C和D只是对B的展开，是B的两个方面，面太窄。只有B才是文章自始至终谈论的主题。

 

无明显主题句

The Egyptian kingdom was not self-contained but traded widely with the outside world, using the enormous surpluses of wheat grown on rich valley soil to profit from high prices resulting from famine in various part of the Mediterranean world. Relations with the neighboring and in some way similar civilization of Mesopotamia were always close, though often hostile. Syria and Palestine suffered much in biblical times from the competition of the two world powers of the day. For a long time, Egypt ruled over Syria but gradually its power declined and it was itself conquered, first by the Assyrians(6632B.C.).

 

This passage is mainly about      .

A. the early history of Egypt

B. wheat trade between Egypt and its neighbors

C.the fall of Egypt

D. famine in the Mediterranean world

 

答案是A。本段的主题思想并非直接由一两个句子表述，而是在文中间接暗示的，这就需要根据文中细节进行概括与归纳。B、C、D均与细节有关。
