Sample essay:

Dear Tom,

We made an appointment to go on a trip to Beijing together next weekend, but I am very sorry to inform you that I can not go with you this time. Last night, my mother suddenly fell ill and my father and I were so worried that we took her to hospital. The doctorchecked her over and said she was over-worked and needed to stay at home and rest for a week. My father has to go on a business trip next week, so I have to look after my mother during that time.

Anyway, we will have many more chances to visit Beijing. Shall we make it on July 14 and July 15, when I will have some time available?

Thank you for your understanding. I am looking forward to your early reply.
