雅思写作考生常犯错误
其次，如何展开一个观点，关键在于是否能够灵活运用论证方式。常用的论证方式包括：解释（explanation），延伸（extension），举例（exemplification）和对比（contrast）等，如：
A lot of innovations are made with the aim of making money for a few. This is because it is the rich and powerful people in our society who are able to impose changes (such as in working conditions or property developments) that are in their own interests. （第二句为解释论证）（《剑6》Test 4）
My view is that young people should be encouraged to broaden their horizons. That is the best way for them to get a clear perspective of what they are hoping to do with their lives and why. (第二句为延伸论证) （《剑5》Test 2）
To do this, we need to improve the choice of public transport services available to travelers. For example, if sufficient sky train and underground train systems were built and effectively maintained in our major cities, then traffic on the roads would be dramatically reduced.（第二句为举例论证）（《剑8》Test 3）
The reasons for this trend may involve the recognition that a young adult who passes directly from school to university is rather restricted in terms of general knowledge and experience of the world. By contrast, those who have spent some time earning a living or traveling to other places, have a broader view of life and better personal resources to draw on. （第二句为对比论证）（《剑5》Test 2）
最后，提高写作速度，其关键在于“固定”。要想在那么短的时间内，在考场上高度紧张的状态下写出满足字数要求同时又非常优秀的文章来，的确是非常困难的，但是雅思考官曾讲过，考场上任何一篇优秀文章中的每一个单词都是经过精心准备的。因此，要想保证字数同时又保证质量，考前精心的准备和设计是非常必要的。如：
固定开头段
The late 20st century witnessed the every surging boom of advanced technology, which has brought attention to a heated debate concerning whether housework should be accomplished manually.
The late 20st century witnessed the ever surging boom of the world population, which has brought attention to a heated debate concerning whether people should be encouraged to move into skyscrapers.
固定常用句型
引导观点或者解释论证
It is a widely held perception that…
It is a commonly shared convention that…
举例子
A great case in point is that…
延伸论证
So…that…
对比论证
主语+should/would/could/might + do +其他+ if +主语+did/be(were) +其他
连接两个观点
Not only…but also…
注意：文章中固定下来的内容，尤其是开头段、结尾段和文中的一些固定句型，最好不要摘自比较流行的辅导参考书，避免被考官认为是抄袭或者模板。因此，考生需要自己总结或者在阅读国外期刊杂志以及相关网站原版内容的过程中不断积累，同时还要保证固定内容不能超出自身英语水平太高，否则，被考官认定是语言记忆片段的可能性较大。把固定下来的内容运用熟练，就可以有效地提高写作速度，从而满足字数要求。
