Dear Ting Ting，
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 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，
Grandma

Dear Grandma，
Thank you for your letter and the check。 It was really kind of you to send me so much money。
I spent one week at an ecology summer camp in the countryside。 Yes。 We did see a snake。 Five of the boys drove it away。 I was excited when they did it。
Thank you for your good wishes about my knee。 That afternoon， after I returned to school， I fell over on the stairs。 It was not serious and it"s getting better now。
Since I am very interested in nature， I"ve decided to spend the money you sent me on a telescope。 I can use it to observe natural things。 Will that be all right？
With lots of love。
Yours，
Ting Ting
