大作文分为种：
A. descriptive： cause & effect, davantage & disadvantages
B. argumentative: discuss both views, agree or disagree?
但是，雅思出题也会把上述的任意两款综合起来，形成一个hybrid混血儿。无疑，增加了考试难度。下面就剑八里出现的一道命题，浅谈如何回应的方法：
Some people think that increasingthe price of petrol is the best way to solve the growing traffic and pollutionproblems. To what extent do you agree or disagree? What other measures do youthink might be effective?
【Task Response】
解题关键字：petrol price, best way, traffic and pollution,other measure
题型：混合型，既要讨论观点具有多少程度的合理性，又要提出其他办法来补充前面的提案。
Theissue of road mess and environmenthas never allowed us to feel comfortable. Thus, many people suggest an increase in energy to control the traffic and emission which is clearly contributed by vehicles. It is obvious that the modern tool of transport does more harm than good. So, if the petrol price is increased to certain level, the useof them will be reduced to some extent.As a result, the pressure on cities will be decreased. However, I do not believe that this is only approach to solving this issue, because there are other factors contributing to the phenomenon. （粗体字为必须掌握的词汇，划线部分重点句型）
【Introduction】解题 –顺水推舟，往命题靠拢，先讨论命题观点的合理性，再将话锋移转到你所持的看法与主张。既体现你的思想成熟全面，又不失时机地平衡两个大方面，还把字凑足了。该段结尾时，丢出主题句，顺利过渡到主体段的展开。
