Dear John，
Thank you very much for your recommendation. It’s great opportunity to take part in the English speech competition. Therefore, I'm afraid that I can't attend it. My mother had been ill for several days and I have to take care of her in my spare time, because I don't have enough time to prepare for the speech competition.
I strongly recommend my friend Zhang Ming, who I think he is the most suitable person to participate for this competition. He is good at English and speaks fluently English. Besides, he is a member of the wild animal protection club and devotes much time to care animals. I'm sure his rich experiences of animal protection and perfect speaking English will enable him to achieve success.
Sorry again for my absence.
Best wishes.
Yours,
Li Hua

Dear Chris,
Are you exciting about our coming volleyball game against No.1 Middle School next Friday? Now I will give you an introduction for the game so that you can make full preparation for it.
First and foremost, the competition to take place in our school stadium will begin at 2 pm, last for roughly 3 hours. So significant was the game that it is required that everyone should present ourselves punctually. What’s more, it is necessary for you to take good rest, that will provide enough energy for you. To sum up, I wish you could live up to the expectations of our school. And I firm believe hard work will pay off it!
Yours truly,
Li Hua
