Dear Paul,
Thank you very much for your letter. I’m glad that you enjoyed yourself with us in the holiday in London.
We enjoyed staying with you and your sister Betty. We hope that both of you can come again next year. Why not stay longer next time? A week is not really（确实）long enough (足够的), is it?
This September Tommy and Ann will be in Grade Seven and I will be in Grade Nine. I have to work hard. My math is not good. Can you help me?
Tommy and Ann went for a picnic yesterday. I didn’t go with them because my foot was hurt and I couldn’t walk. They went to an island (岛) and played some games there. Do you remember the island? That’s where the five of us had a good time last month.
Best wishes.
Yours,
Michael
