阅读中如何找主题句来确定中心思想

主题句是指表述段落主旨的句子。主题句体现了文章的方向，对文章起指导和限定作用。主题句的全部含义和意义都靠其他句子去体现，去展开和确定。它具有如下特点：有明显的概括性；句子结构简单；段落中其他句子均用来解释支持或扩充主题句所表达的主题思想。The green plant is a kind of food factory.

It takes matter from soil, air and water and changes it ito the matter we call food. The green plant makes the kinds of matter we call sugar,starches, fat and proteins. The green plant is also astorage place for those foods that animals must eat.

本段的主题句就是段首第一句。

Good manners are important in all countries, but ways of expressing good manners are different from country to country. Americans eat 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 person’s behavior toward another person. In all countries it is good manners to behave considerately toward others and bad manners not to. It is only the way of behaving politely that differs from country to country.

这段的主题句则在首尾，前后照应，两次点题。

2.有些段落没有明显的主题句，主要通过细节的陈述含蓄地表现段落的主题。这时，无法在段落中找到主题句，须要将不同的细节所集中描述的要点综合概括得出该段的中心思想。在阅读理解题中，针对主旨大意的理解题，尤其是针对“title”的题型，主要考查读者的逻辑概括能力。如”

The other day I wanted to send a present by post. So first of all I found a cardboard to put it in. Then I wrapped the box in brown paper. I tied the paper round tightly with a string. Having made the parcel secure, I wrote the name and adress in large letters on the front. After that, I took it to the post office to have it stampped.

读完这段文字你会发现找不到现成的主题句，把寄包裹的细节概括起来，便找到其主题思想是：An account of my sending a parcel.

考查文章或段落中心思想的试题通常有以下几种表现形式：

1)The best title for this passage might be _______.

2)The main idea of this passage may be expressed as _______.

3)What is the main idea expressed in the passage?

4)Which of the following best expresses the main idea ?
