In the first part, let's talk about the topics you chose at the beginning, such as building a nuclear power plant, and boys should enter school before girls. First of all, this has caused great controversy in society.

The second part is divided into two small parts, which discuss the dispute respectively. In the first part, write an aspect, such as the voice of supporters, list several reasons, and give some examples to describe it vividly. The second part is the voice of the opponents, same as above.

The third part is to state my own ideas. You can take sides or remain neutral.

Let's sum it up at last.

I hope I can help you!
