You have told me that you are very nervous about the coming speech contest and I will try to make some suggestions which I hope can help you. In my opinion, you should get well prepared before the speech contest by practicing before a mirror. Besides, you had better use a brief and concise language in your speech so that you can leave a deep impression on the judges. When you are giving the speech, remember to keep smile. Even if you forget your words,don't be panic and just continue your speech, because no one will notice it.
Wish you success in the speech!
通过审题，首先决定缩要写的要点：说明回信的意图；向小明提出建议；预祝小明比赛成功（这点在结尾中已经给出）。回信的意图可以一句话交代，所以重点是写建议，结合表格内容，要合理的将材料进行整合加工，也就是要写赛前准备和比赛后要做的事情。在表达要点时，切忌逐字逐句翻译，也不能受汉语影响，要多用固定词组，如：are very nervous about ,make some suggestions, get well prepared, leave a deep impression on。还有固定句型如so that句型，定语从句等，也要注意文章的连贯性，如In my opinion等。
