Dear Xiaohua,

I had a letter from your mother a few days ago ,but she didn’t give me much news about you . She said you went on an ecology summer camp. When I heard that you had seen a snake ,I was worried .I hope someone killed it ! I was sorry to hear that you had hurt your knee. How did that happen? I hope it is better now.

I know your birthday is coming soon ,so I am enclosing（附上）a check for you .Write soon and tell me what you decide to do with the money .I want you to spend it on something nice.

With lots of love,

Yours，

Grandpa
