Firsty,almost everybody assumes that our life cannot be happy without friendship.Absolutely,for our students.boys and girls have different views on a same thing .So it's good for our study to make friends with each other.The key point is one can hardly do a job in a quick way ,otherwise,we cooperate with many people . secondly,as an old saying goes:“A hedge between keeps the friendship green",if we can command the limitation between heterosexual friendship ,we surely can benefit from it. As far as i am concerned,the relationship between boys and girls is beneficial for the growth of adolescents.So i stand for this point.
