It is a common phenomenon thatpeople,including the elderly people as well as some young people, will gather in the dancing square late in the evening due to the fact that people’s physical and mental life develop rapidly.
When it comes to square dance, it is universally acknowledged thatit makes a tremendous difference to people’s life. For instance, not only dancing women promote people’s relationship but also it makes contributions to people’s health. However, dancing has some disadvantages of its own despite its advantages. When dancing, the dancing women play loudmusic unconsciously, which gives rise to dissatisfaction.
Personally speaking, I am definitely infavor of such behaviors. By the way, I do hope the dancing women can try their best to regulate the volume of music. Only in this case can we create a harmonious community together.

参考范文
Recently, students in our class have had a discussion on whether space is worth exploring.
30% of us thinkspace exploration is not worthwhile. They think space is too far away from us and our daily life. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.
On the other hand, 70% thinkspace is worth exploring because we have benefited a lot from it, such as using satellites for communication and weather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day. Also, space research will enable us to find new sources to solve the problem of energy shortages on the earth.
