As teenagers，we grow quickly.In just one or two years，a well-fitting set of uniforms may become too small for us.Many of our old uniforms，when we go to throw them away，are still actually （實際上）wearable.This is a big waste.If there is a program for us to share our old uniforms，we can cut down on （減少） that waste.This is very good for the environment.With a uniform sharing program，we can also save lots of money.
    Some parents in Hangzhou have put this idea into practice.They have set up an online uniform sharing platform （平臺）.But I think we still need to solve a few problems before we start to set up more platforms like this.Firstly，not all old uniforms are suitable to be shared.Clothes like coats and sweaters can be easily cleaned up and shared.But in my opinion，I don't support the idea of sharing summer clothes such as T-shirts.There should be a criterion （標準） for the types of clothes that can be shared.Secondly，students should be allowed to decide for themselves whether they wish to share or accept old uniforms.Perhaps we will form a uniform committee （委員會）.Students who need old uniforms can post a message，and those who have suitable uniforms to share can contact them directly.
