　　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.
