Dear Uncle，
How are you?
Next week an English speaking contest will be held in the city。 A classmate of mine and I will take part in it on behalf of my school。 I am excited but also mervous， because it is a good chance to improve my English。 But I have no experience。 Although I have been preparing for the contest， I am still not confident。 As an expert in English， what would you advise me to prepare for the contest?
I plan to pay a visit to you this Saturday morning。 I wonder whether you will be free then。 If not， could you tell me the time that is convenient for you? I am eager to get your instruction。 I will appreciate any of your help。
Your niece，
Yang Mei
