雅思大作文的引言怎么写

在雅思导言部分，一般包括以下三个要素：

一： 对于题目中提出的论述/问题的重述

二： 对于该论述/问题，表明自己的观点

三： 对于文章的主体段落布局的预先交代

其中，因子1和因子2是必需的组成部分，而因子3是可选的组成部分。如果有的话，文章会更清晰。

让我们看看下面的例子:

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?

这是一个关于我们对计算机依赖的争论。主要的问题是：这种依赖是一件好事还是我们应该怀疑它？让我们来看一个介绍性段落的例子。

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.

该引言部分很好地包含了上述三个要素，现将其细分为三个要素，并作如下分析：

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从头至尾的重述表明，计算机正在极大地改变我们的世界和我们对计算机的日常依赖。

注意句型的使用：although no one can deny the fact that….. and that…..

要素二 观点：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：使用We should be aware of。。。and remain skeptical of。。。这样一个经典的短语表达了作者对计算机潜在损害的认识，以及对日益电脑化的世界的怀疑。

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：使用in three fundamental ways从三个基本方面看，如果我们滥用计算机，将对人类的整体福祉造成三个根本的危害。这种写作方式为下面的主要段落铺平了道路，也就是说，主要段落应该分为三个小段落，每个段落都谈到其中一个危害。
