高考閱讀理解的文章一般由3—5段構(gòu)成，如何把握它們之間的關(guān)系以及段落內(nèi)部的邏輯對(duì)于理解全文有很大關(guān)系。本文只討論段落內(nèi)部的邏輯。理解了這種邏輯，閱讀時(shí)就能抓住重點(diǎn)，關(guān)注次重點(diǎn)，忽略次要細(xì)節(jié)，從而提高做題的正確率。段落的基本結(jié)構(gòu)是：段落主題句（簡(jiǎn)稱為TS，即topic sentence）；段落支持句（簡(jiǎn)稱為SS，即supporting sentences）；段落總結(jié)句（CS，即concluding sentence）。有時(shí)，段落沒(méi)有總結(jié)句，那么段落的結(jié)構(gòu)就簡(jiǎn)化為：TSSS。還有的時(shí)候，段落開始沒(méi)有主題句，而在段末有總結(jié)句，那么段落的結(jié)構(gòu)就簡(jiǎn)化為：SSCS。使情況更為復(fù)雜的是：有時(shí)整個(gè)段落中沒(méi)有明顯的主題句和總結(jié)句，其主題是通過(guò)閱讀者自己總結(jié)出來(lái)的。如:

Smoking cigarettes is harmful to your health.Experiments show that cigarette smoking can cause cancer.Besides the most serious and terrible disease (illness), cancer, cigarette smoking also can cause other health problems.For example, it can give one a “smokers cough”.Finally, studies have shown it is easy for cigarette smokers to catch colds.Whether you get an unimportant cold or terrible killer, cancer, smoking is harmful.Is it worth it?

這一段文章中主題句(topic sentence)是：Smoking cigarettes is harmful to your health.

總結(jié)句(concluding sentences) :Whether you get an unimportant cold or terrible killer, cancer, smoking is harmful.Is it worth it?

這篇文章的機(jī)構(gòu)是：TS-SS-CS 即：

Often no one looks more guilty than the innocent.On the other hand, nobody may look more innocent than a professional criminal.And the man who knows “everything” may really only be trying to hide his own weakness.So, it is foolish to try to judge a person only by his appearance.

這段文章沒(méi)有主題句，它的主題是通過(guò)總結(jié)句體現(xiàn)出來(lái)的。

支持句：Often no one looks more guilty than the innocent.On the other hand, nobody may look more innocent than a professional criminal.And the man who knows“everything” may really only be trying to hide his own weakness.其中often, And, On the other hand 等都是用來(lái)陳述或強(qiáng)調(diào)事實(shí)。

總結(jié)句：So, it is foolish to try to judge a person only by his appearance.

這篇文章的機(jī)構(gòu)是：SS-CS. 即：
