Dear Mary,

Thank you very much for inviting me to your party. I am very happy. However I cannot come, I am sorry about it.

Currently, my mother was sick, and not getting better. Last week, we went to the hospital, doctor told her that she had to stay at home, and had few days break. Therefore, I need to take care of my mum this period of time.

I have received your card, very beatiful, I like it very much. Now I am writing this letter while watching the card, because I put it on my desk,.it is in the front of me at this moment. I really love it. Thank you.

如果句子觉得还不够，我在想想添几句

Dear Mary

I am sorry I could not go to visit you on time. My mother is not very well and she has stayed in bed for a couple of days. I have to look after her. Thank you to send me a nice postcard and I like it very much. It stands on my desk now. It is easy for me to see it everyday. I miss you .

Thank you very much for inviting me to your party.

Keep in touch with me

Best regards

Zhang Yang
