雅思写作命题者涵盖的话题不计其数，题型也不止一种，这就要求考生在备考过程中，不能仅仅拘泥于准备雅思写作的一部分话题，而应该在了解了雅思写作命题的三大题型基础上，有针对性地对每一类的话题做出相应准备。
从命题的形式上看，雅思写作可以分为以下三大题型：
1.辩论型题目(argumentation)
辩论型的雅思写作题目是很常见的。通常就是题目给出两个事物或两个观点，让你任选其一;又或者是摆出一个事物或一个观点，问你是支持还是反对。考生需要表明观点，然后通过论述分析，支撑自己的立场。这类试题在考试中占70%左右。
例: Children who are brought up in families that do not have large amounts of money are better prepared to deal with the problem of adult life than children who are brought up by wealthy parents. Do you agree or disagree?
例: Some people believe that the best way to produce a happier society is to ensure that there are only small differences between the richest and the poorest members. To what extent do you agree or disagree?
2.解释型题目(explanation)
解释型的雅思写作题目会给出一个现象，让你说明现象的原因或/和给出解决方法等。这类试题在雅思写作考试中大约占20%。
例: Many young people today leave school with a negative attitude towards learning. Why do you think this is happening? What can be done to encourage young people with a positive attitude towards learning?
例:What are the causes of water shortages? Please also offer some solutions to deal with this problem.
3.混合型题目(Mixed)
雅思写作的混合型题目中包含两个问号或要求，其中一个是辩论型题目，一个是解释型题目。
例: More young people in the workforce change their jobs or careers every few years. What are the reasons for this? Do disadvantages outweigh advantages?
例:In some countries, the national traditional arts are facing extinction. Some people think that the government should support them. Do you agree or disagree? What should the government do?
以上就是雅思写作命题形式的三大题型，考生需要掌握每一种题型的写作方法和技巧，才能应对千变万化的雅思写作话题。
