例题：The only way to improve safety on the road is to impose severe punishment on driving offenders. To what extent do you agree or disagree?
开头段示范：As there is a sudden rise in car accidents in the past few years, how to maintain road safety has triggered a heated discussion among the public (背景介绍). It is sometimes argued that punishing drivers who disobey traffic rules is the only solution to this problem (观点重述). However, I disagree with this view to a large extent (作者立场).

最后一句话是阐述作者的立场。除了同意，不同意这两个整体立场外，还要把立场的程度说清楚。一般会有三种可能性fully, largely, partly. 可以借鉴的句型是I would fully / largely / partly disagree with this point of view.

It is sometimes argued that governments should pay for the full tuition fee for all students who are admitted by a university. I tend to disagree with this idea to a large extent.
