在雅思的引言段中，一般會(huì)包括以下三個(gè)要素：
一： 對(duì)于題目中提出的論述/問題的重述(restatement of the issue)
二： 對(duì)于該論述/問題，表明自己的觀點(diǎn)(your opinion of the issue)
三： 對(duì)于文章的主體段落布局的預(yù)先交代(layout of the main body)
其中，要素一和要素二是必要組成部分，而要素三是可選擇的組成部分，如果有的話，會(huì)使文章看上去條理更清晰，層次更分明。
我們來看下面的例子：
We are becoming increasingly dependent on computers. They are used in businesses, hospitals, crime detection and even to fly planes.
What things will they be used for in the future? Is this dependence on computers a good thing or should we be more suspicious of their benefits?
這是一篇談?wù)撐覀儗?duì)計(jì)算機(jī)的依賴性的議論文，主要問題針對(duì)的是：這種依賴性是一件好事還是我們應(yīng)對(duì)它感到懷疑?下面我們來看這個(gè)引言段的范例：
Although no one can deny the fact that computers are transforming our world and our lives in an astonishing way and that we rely on them for our daily existence. We should be aware of their potentially damaging impacts on many aspects of our social life and remain skeptical of the over-computerization of our world which is ardently advocated by some scientists. In my opinion, computers may jeopardize the overall wellbeing of humans in three fundamental ways if we misuse them.
該引言段很好地包含了以上提到的三個(gè)要素，現(xiàn)將該段按三要素分解并分析如下：
要素一 重述： Although no one can deny the fact that computers are transforming our world and our lives in an astonishing way and that we rely on them for our daily existence.
分析：以although開頭的讓步狀語從句來進(jìn)行重述，說明計(jì)算機(jī)正在急劇地改變著我們的世界以及我們對(duì)計(jì)算機(jī)的日常依賴。注意句型的運(yùn)用：although no one can deny the fact that….. and that…..
要素二 觀點(diǎn)：We should be aware of their potentially damaging impacts on many aspects of our social life and remain skeptical of the over-computerization of our world which is ardently advocated by some scientists.
分析：用We should be aware of。。。and remain skeptical of。。。這樣的經(jīng)典詞組來表達(dá)作者對(duì)計(jì)算機(jī)潛在破壞作用的情醒認(rèn)識(shí)以及對(duì)日益計(jì)算機(jī)化的世界的懷疑。
要素三 布局： In my opinion, computers may jeopardize the overall wellbeing of humans in three fundamental ways if we misuse them.
分析：用。。。in three fundamental ways來說明如果我們?yōu)E用計(jì)算機(jī)的話，它將對(duì)人類的整體福祉造成三個(gè)根本性的危害作用。這樣的寫法就為下文的主體段落作好了鋪墊，即主體段應(yīng)分為三個(gè)小段落，每段分別談?wù)撈渲幸粋�(gè)危害之處。
