帮忙看一下这篇英文短文有什么错误的地方
Dear Rode,
First,invite them more to take part in some meeting and activities,which can make their English a great progress and help them get away from solitude.And it also can help you know more about Chinese culture and get more knowledge of Chinese.
Second,help them more with their study,which can not only help them improve their study and ger good grades but also make them think you are friendly and speak highly of you.
Third,don't laugh at them when they make some mistakes.If you laugh at them,they will annoy with you.
If you do all that I advise,you'll get along well with them.
All right,that's all.I hope you can write me soon.
Yours
