Dear Li Ming，
My parents and I are going on vacation tomorrow。 I went to your house， but you weren’t in。 I need some help。
Could you please feed my dog? And could you please sleep in my room for a week? Could you please take care of my car? Could you water the flowers and cut the grass? And there is some food in the kitchen and you can eat it。 You can get the key from the shop assistant。 Have fun! See you next week。
