Dear Ms.Iris,
Thank you for taking the time out of your busy schedule to talk to me about the English Summer Camp of Canada in August with YJ company.
Just to remind you to send me the files and documents related to the camp. ( Would you please confirm that you have send the files and documents related to the camp to me? ) kindly remind that I didn't find the files related to the camp, as I cannot find a Email attached files from you in my neither inbox nor Junk-box.
考虑发邮件对象，语气非常重要。之前的语气生硬，表意的话歪果仁可能不容易理解你为什么这么写。
In addition, this is my first time go aboard. I feel excited, but I have no idea about what I should prepare for my aboard life. I understand that your schedule is probably very tight: hence any amount of help you can give is very much appreciated.
Please feel free to contact me at any time if further information is needed or any information regarding the camp updates . My cell phone number is XXX XXXX XXXX.
Thank you so much for the time and thanks in advance for the time of you.
Sincerely,
Grace
