2.介紹雙方觀點+說出自己的觀點
例1：
young people tend to think that real life is as dramatic and fascinating as it is in the novels and movies, while more experienced adults disregard this opinion. adults think this kind of na?ve daydream will only be destroyed by later experiences and every one should learn to get used to tedious everyday life. in fact, i believe that realism is necessary, but idealism is more important to increase the quality of our life.
