书面表达（英语） 根据提示写回信

Dear Li Hong,
I can understand your feeling now.I think it would be better if you calm down and find the reason why you quarrelled with him/her first.Then I suggest you to keep a good mood yourself and try to control your temper when you get angry.Offering help to others regularly is a good way to get on well with them.One more thing,you should learn to be cooperative,and people like to be with a person who has team spirit.I believe you will surely have more friends if you follow the suggestions.Don't worry.Things will be better.As your best friend,I always trust and support you.请其他同学勿转载,希望可以帮到提问的同学）
Sincerely,
Emily
