在各類英語考試閱讀理解題中，推斷主題大意題所占比例較大，幾乎每一文章都設(shè)一個(gè)主旨題。出題者意在通過此題考查考生語篇能力。那么，怎樣才能準(zhǔn)確地把握住短文的主旨大意呢？從以下的實(shí)例說明我們便可得到滿意的回答。
All students of geography should be able to interpret a weather map accurately. Weather condition an enormous amount of information about wealth condition existing at a time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a month it issues a 30-day “out-look” which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day out-looks are based upon an analysis of the upper air levels which often set the stage for the development of air masses, frosts and storms. 來源：考試大
大至每篇文章，小至每一段落，都必然有一個(gè)主題。這是因?yàn)槿魏挝恼拢ɑ蚨温洌┒际菫榱讼蜃x者說明一個(gè)段落或闡述一個(gè)觀點(diǎn)。因此，我們?cè)趯?shí)際處理這一類型的題時(shí)，最關(guān)鍵、最根本之處就在于怎樣去分析、把握文章（或段落）的主題。
一篇文章（或一個(gè)段落）可以有很多的次要思想（minor ideas）h和論證性細(xì)節(jié)（supporting details）,但中心論點(diǎn)或主題思想（theme,main idea）一般只有一個(gè)。中心思想起主導(dǎo)作用，論據(jù)是主題的從屬，它們之間是“主干”與“分枝”的關(guān)系。在考試中，如果這種關(guān)系沒弄清楚，必然導(dǎo)致判斷錯(cuò)誤。現(xiàn)以上文為例，綜觀全文，我們發(fā)現(xiàn)，原文從第二句開始以下各句都是圍繞著第一句這個(gè)中心來解釋：Why should they develop this ability?作者是從幾個(gè)方面加以解釋：一是map信息包容量大；二是覆蓋面大；三是速度快；再就是可作為期三十天的氣象展望；還可有效地預(yù)報(bào)災(zāi)難性天氣。而作為一個(gè)學(xué)地理的學(xué)生看懂這樣的氣象圖是必不可少的。所以說原文第一句和下文是一種主從關(guān)系。了解了這一點(diǎn)，就不難推斷出本段的主題思想了。
Question：
What is the main idea of this passage?
[A]Weather maps are very impotant to students of geography.
[B]Weather maps can have a 30-day “outlook”.
[C]Students of geography should be able to make weather maps accurately.
[D]Those who major in geography should possess the ability to have a good understanding of a weather map.
有些考生認(rèn)為，只要選擇答案在原文中能找到對(duì)應(yīng)的句子就肯定是正確答案了，其實(shí)這是一種誤解，實(shí)際上有時(shí)能直接找到答案的選擇項(xiàng)正好與正確答案相反。從以上的四個(gè)選擇答案看，我們都能在原文中找到相應(yīng)的句子，但它們并非都是文章主題思想。A項(xiàng)只說氣象圖對(duì)學(xué)習(xí)地理的學(xué)生十分重要，但未進(jìn)一步說明在哪一方面重要。假設(shè)A項(xiàng)是本文的主題思想，那么，文章的下一步發(fā)展就應(yīng)該對(duì)這一論點(diǎn)作進(jìn)一步的論述，只有這樣，才能說服讀者。但原文的發(fā)展并非如此，所以A項(xiàng)非正確答案。B項(xiàng)更不能充當(dāng)本文的主題。因?yàn)?，它只是說明weather map 中的一個(gè)功能。整篇文章都未涉及students要去制做weather map，因而C項(xiàng)也與原文大相徑庭。只有D項(xiàng)與原文的主題句相吻合。
從以上的分析，我們可得出這樣的結(jié)論：辨認(rèn)主題句是獲取段落（或短文）主旨大意的關(guān)鍵所在。何謂主題句呢？凡表述段落（或短文）主旨大意的句子就叫主題句。主題句一般具有三個(gè)特點(diǎn)：
（1）意義表達(dá)的總領(lǐng)性比較強(qiáng)，相對(duì)其他句子來看，這種概括性更為明顯。
（2）句子結(jié)構(gòu)較簡單，多數(shù)都不采用長難句的形式。 來源：考試大
（3）段落中其他的句子一定是用來解釋、支撐或擴(kuò)展主題句所表達(dá)的主題思想
