In some countries, parents expect their children to spend long time studying both in and after school and have less free time.What are the positive and negative effects on children and society they live in?

请问@Lynn 老师，像这样的题目，需要拆开来分别论述吗？
比如：positive on children, positive on society, negative on children, negative on society 都需要写到吗？

如果都需要论述的话，段落划分是这样吗？
body 1：positive on children 和 society
body 2：negative on children 和society

如果这样写的话，因为每个body的内容都比较多，是否不需要举例子呢？
