Dear Liz，

Thank you for your great present．I had a successful birthday party last Saturday.Ten of classmates came to my home．Well,we played games,danced to music and enjoyed delicious food．We shared a big cake with a small chocolate monkey．My mum bought the cake．Miss Smith was a special guest(客人)．She happened to meet my mufti in the cake shop near my home．She also joined us and drew a picture for me．I was happy to receive many kinds of presents，such as cards．balls and CDs．Your book about animals was the best．You know,I like animals and dogs are my favourite．There is a small black cat in my grandparents' home．I'd like to play with—it when I visit my grandparents once a week．It's cold today．What's the weather like in your village? Let's go to the new library when you come back．

Yours，

Elizabeth
