2.【lessonsapersoncouldlearnfromhavingaroomate写一篇引文作文80字

In my opinion,to have a roommate is a good thing when you study at a boarding school.You can learn many things from having a roommate.First of all,you should learn how to make friends with your roommate.You need to be sincere and considerate.only when you treat a person with all your heart,can you win him/her over.Sharing a room with someone is somewhat like living in a family,so you need to learn to help each other when you both meet with difficulties.Last but not the least,don't forget to share what you feel especially when you are unhappy,he/she might be a great help.You certainly learn a lot if you have a roommate.希望对你有启发。
