考研英語寫作的時候，寫好段落也是很重要的。我們平時寫的文章往往都是由幾個段落組成，和句子一樣，段落也是為文章的中心思想服務(wù)，形成一個有機(jī)的整體。跨考考研張老師認(rèn)為好的段落必須是意思完整，語義連貫，完全體現(xiàn)文章主旨中心，同時又是層次分明，結(jié)構(gòu)嚴(yán)謹(jǐn)，邏輯關(guān)系應(yīng)用合理的。

　　一、段落的組成

　　一個段落由三部分組成：

　　1.主題句(Topic Sentence):點出段落的主題(談?wù)撌裁?。

　　2.擴(kuò)展句(Developing Sentence):說明和支持主題。

　　3.結(jié)尾句(Concluding Sentence):得出結(jié)論。

　　二、段落的主題

　　一篇文章有中心意思，也就是題目。而每個段落則有段落主題，段落主題是為文章中心思想服務(wù)的。

　　每個段落只能有一個主題(central idea)，它用一個句子加以表達(dá)，所以稱為主題句。主題提出后需要很多結(jié)構(gòu)嚴(yán)謹(jǐn)?shù)木渥觼碇С趾驼f明，稱為擴(kuò)展句。最后得出一個結(jié)論，并用一個結(jié)尾句表達(dá)。參看下面段落：

　　(主題句)Slavery in the United States existed almost unchanged for 250 years.(擴(kuò)展句1)During this time, most slaves were not allowed to marry or to raise families.(擴(kuò)展句2) Usually they were not allowed to learn to read.(擴(kuò)展句3) It was very dangerous for a slave to travel, since even free Negroes could be kidnapped and sold at any time. (結(jié)尾句)Under these conditions, it was almost impossible for them to organize to help each other.

　　三、寫好主題句

　　定義：主題句為一個完整的句子，用以概括、敘述和說明該段的主題。

　　位置：主題句一般位于段首，也可置于段尾或段中，考生最好放在段首，這樣較易掌握和構(gòu)思。例如：

　　位于段首：在英文中，大部分段落的第一句便是主題句。開門見山地提出問題，后面的擴(kuò)展句圍繞主題句加以說明、支持、補(bǔ)充和解釋。

　　Learning English at college is different from learning English at the middle school. In the middle school, the students are more dependent and passive. But college students must solve most of the problems by themselves. They will have to consult the dictionaries and reference books by themselves and prepare their lessons.

　　位于段尾：主題句位于段尾便于總結(jié)全段的內(nèi)容，給讀者以深刻的印象，是寫作中的一種演繹方法。

　　Similarly, in order to write successful answers to essay questions on history or anthropology examinations, a student must arrange the relevant facts and opinions according to some accepted pattern of paragraph structure. And certainly when a student writes a book report for English, or a critiques for politics studies, or a term paper for sociology, style and organization are often as important as content. Clearly, the ability to write well organized, concise paragraphs and essays is essential to a student’s success in almost all university courses.

　　位于段中：位于段中的主題句起承上啟下的作用，這類主題句多起轉(zhuǎn)折作用，一般由“but, however, yet, anyhow, nevertheless”等詞連接，用于引起下文。

　　What we teach ourselves sometimes indeed in more useful than what we learn from others. Some great men had little or no schooling. But these great men probably studied harder by themselves than most boys do in school. The greatest minds do not necessarily of those who have never been able to distinguish themselves at school, have been very successful in life later. It has been said that Wellington and Napoleon were both dull boys at school, and so were Newton and Albert Einstein.
