A Letter for HelpDear 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.
