帮忙写篇英语作文 不要有语法等错误 不要网上找的

Dear Smith's, I am writing this letter to express my sincere gratitude for your help and assistance to me in language and living during the two weeks stay in Australia with your family。 You took me out a couple of times for tours and introduced the exotic local culture to me。 I had so much fun and I hope you had a great time too。 I cannot imagine what it would be like without you as I had language barrier and went through a series of culture shocks when I first came。 You were patient to listen and encourage me to speak so that my English has improved a lot。 As I am going to leave this country tomorrow, I would like you to know that every bit of the time here in Australia has been the most memorable experience in my life。 I am sure that soon I am going to miss you and the life here when I hit China。 Wish you a good life and keep in touch!Best regards,Li hua
