Dear Frank,
Thank you for your postcard. I'm very glad you are having a good trip now. Ottawa is very beautiful in May. I hope I will have a chance to go there one day.
Our summer holiday will start next month. I enjoy my summer holiday, although(虽然)it's hot at that time in America. During the summer holiday, I can swim in the sea and go fishing. It's so cool. And I am going to our hometown near Chicago with my sister Linda, and my parents agree(同意). Our uncle lives there, so Linda and I can stay with him.
We are not going to take a plane. We are going there by train. I am going to fish there. And Linda likes painting. She is going to do some painting there. I'm sure we'll have a good time.
Sincerely,
Jack
