1.Write a response in which you discuss the extent to which you agree or disagree with the statement and explain your reasoning for the position you take. In developing and supporting your position, you should consider ways in which the statement might or might not hold true and explain how these considerations shape your position.
个人理解：首先，这个introduction所对应的issue题目一定是个称述型的statement。做题者可以同意或反对，或者参半。在论述过程中，一定要考虑到有什么方法，可以让这个statement的对错性改变。
2.Write a response in which you discuss the extent to which you agree or disagree with the recommendation and explain your reasoning for the position you take. In developing and supporting your position, describe specific circumstances in which adopting the recommendation would or would not be advantageous and explain how these examples shape your position.
个人理解：这个要求和第一种基本雷同，同一道题目，基本上，两种introduction都可能出现，主要区别在于，这个强调的是recommendation，也就是建议，一般来说，也是针对一种行为，或者措施的陈述事实的句子。而在论述当中，一定要分析到circumstances，也就是大环境，对这个行为或者措施的效果的影响。例如，明确分析，在什么情况下，这样的建议可能不能达到起预期的效果。
3.Write a response in which you discuss the extent to which you agree or disagree with the claim. In developing and supporting your position, be sure to address the most compelling reasons or examples that could be used to challenge your position.
个人理解：这个主要是对一个声称或者主张的讨论，重点在于，在论述中，要涉及，与考生自己观点对立的理由及例子的分析，也就是类似反正自己的观点。
4.Write a response in which you discuss which view more closely aligns with your own position and explain your reasoning for the position you take. In developing and supporting your position, you should address both of the views presented above.
个人理解：这中instroduction 比较特殊，所针对的题目本身，肯定存在两个观点。那么考生在论述时，要指出哪个和自己的观点比较接近，而且在论述过程中，必须对题中的两种观点，都进行分析
5.Write a response in which you discuss the extent to which you agree or disagree with the claim AND the reason on which that claim is based.
个人理解：这个是最普通的，基本上和老
6.Write a response in which you discuss your views on the policy above and explain your reasoning for the position you take. In developing and supporting your position, you should consider the possible consequences of implementing the policy and explain how these consequences shape your position.
个人理解：这个特指，正对某个政策。而且考生在论述过程中，必须涉及如果实施这个政策后，可能带来的诸多效果，对效果进行分析，从而推出政策本身的好坏。
