雅思写作论证思路讲解.

　　根据澳际培训老师的分析，雅思写作大作文出题都是比较典型的议论文类型，因此雅思写作论证思路就是雅思写作能否获得高分的关键，这个逻辑推理的过程必须严密。

　　雅思写作论证思路1、对比论证

　　对于是否应该做某事这样结构的雅思写作题目，澳际培训老师推荐的是通过对比的方式来引导整个论证过程，两种截然相反或者不同的事物对于，其结果的利弊也就会更为凸显。

　　下面这段就是节选自一篇关于大学前是否应该用一年时间旅游或者工作的雅思写作范文，之所以能成为范文，很大程度上都得益于对比关系贯穿了整个论证过程，这篇文章看起来紧凑而严谨。

　　“Those who believe in the measure say that students benit a lot from traveling or working for a year bore their formal university education. First, they can more broadly acquainted themselves with the society, deepen their understanding of the outside world, and thus better coordinate their objectives of learning with the needs of the society. In contrast, by immediate entrance to university they can not steer the direction of their study well and may display a poor combination of the theory with practice. Second, study at high school is really exhausting, especially when to win college admission. So it is necessary to grant these children a relatively long period of relaxation or buffer, say, traveling or working for a year, to loosen the chords of their brain, so that when they go back to school later again, they can become completely rreshed and rejuvenated.”

　　可以看到这是这一段就是论证的过程，而In contrast作为明显的转折信号词，在此之前，先从正面阐述了如果能在上大学前去旅行或者工作一年，那么学生就能融入社会，再进入大学就能更好地把理论和实际结合起来。In contrast之后则更详细的从反面阐述了直接进入大学的坏处，这样正反结合的对比论证写作思路，很大的一个优势就是，正面很突出，反面也很明显，有足够的说服力。

　　相比之下，如果同学们一直采用正面的论证，以大学前去旅游或者工作的优势贯穿整篇文章的话，或许你也可以有充足的论据，很好的论证，但是总会显得比正反论证“无力”许多，要记住，正和反是个很好的搭档，一个简单的比喻，如果是你用黑色的背景，再用黑色的字，那么不管字多大都不会有人能看出它来。黑和白在设计的色彩搭配中为什么是经典?就得益于两者通过对面后能加强效果。

　　雅思写作论证思路2、假设论证

　　提出假设——推出假设的后果——最后再提出结论，这在很多雅思写作话题中也是经常被运用到的写作思路和论证方法，它的优势在于假设能够将“很虚”“很空”的话题一下子具体到具体的事物上，这样再论证结果的话就不会显得“空泛”。

　　下面就是一篇论证石油是经济和政府命脉的雅思写作话题，而石油本身来说，其实离每一个考生个人的生活还是比较遥远的，因此在假设石油匮乏的前提下，同学们就可以将石油带来的影响波及到农业、工业等等一连串与我们生活息息相关的东西上，这样“石油是经济和政府命脉”这样一个虚、泛的话题就具体化了。

　　Then, since the transportation system is the lifeline of a country’s economic activities, its paralysis would lead to the disintegration of the economy, either industry of farming or daylife. Suppose all the means of transportation were halted for lack of oil, factories with insufficient raw materials would have to close, workers would be out of work, and ripe farm crops would have to stay in the fields at the mercy of rain and storms. People would try to store food and the price of all commodities would go up. If we take those power stations run by oil into account, situations would become even worse. In this sense, oil decides the fate of the whole economy and that of the government.

　　以上提到了假设论证的雅思写作论证技巧，但其实如果同学们对假设和对比两种论证方法都比较熟练的话，甚至可以结合两种论证方法。
