简单总结了下有4点:
1. stand, not vague
2. indicate the point, for example controversial
3. one main idea, not two or more
4. specific, not too big and hart to manage
我的开头:
Arts, the great creation of human nature, has played more and more important role in our society. I agree with the statement that arts reveal the otherwise hidden ideas and impulses of a society in some sense. However, in addition, it also reflects some authors' individual thoughts and emotions.
