Mary写信感谢朋友Carol在自己度假期间对宠物小狗的照顾.Mary相信Carol对小狗很好,因为回来时看见它是那么高兴.以前每次自己度假回来,去寄存中心(the kennel)接它时它总是非常难过(whimper),要持续几个小时.

Dear CAROL:
I'm very thank you for help my small dog.I believe you can help it very good,becanse the dog was fun when I went to home.
Before the holiday,every time I went to look him,he always whimper,keep a long time.
I'm surping with him,as a resuIt I'm thank you for yours.
Yours,
Mary.
