In this article, I give some examples for an introduction paragraph.
Population control policies like China’s one child policy are a good way to fight poverty. Discuss it.
The great population growth is one of the problems in many countries with no exception for Indonesia because it impact to the level of wealth and education of their citizens. Because of that, many countries have tried to control it and people thought that China is one of the successful countries on controlling their population. They made a policy that asked their citizen have one child in a family. China thought that the policy was good way to solve the poverty problem. Unfortunately, it is not really true and suitable for other countries because it has some disadvantages while it also has some benefits.
Comment <from an IELTS native tutor>: Very good. This is a very good introduction paragraph and address the main issue.
