假定你是李华，计划和同学去敬老院（nursing home）陪老人们过重阳节（the Double Ninth Festival），请给外教露西写封邮件，邀请她一同前往，内容包括：
How are you doing? I am LiHua, a 17-year-old teenager currently studying in your school. Recently, our class plan to visit the nursing home this Sunday in order to help the old there and enrich our afterschool life. As the vice monitor, I would like to invite you to come with us.
Here are some details about this activity. To begin with, we will leave the school by bus at 8:00 AM and return at 5:00 PM. Besides, there will be a lot of activities such as making Chinese dumplings and giving performances, which will be not only meaningful but also interesting.
Hopefully, you would like the plan and join us. I have the confidence that we will have a great time there. Thanks for reading my letter. I am looking forward to your reply and your decision.
