三年級作文:My “sister”

I have a “sister”. She is cute and active. Yesterday we went to a village. We flew kites. The weather was windy. Suddenly my hat flew into the lake. I was angry. My “sister” saw the hat. She jumped into the lake and swam to the hat. She returned the hat to me. I was very happy. Then, we went swimming. Five minutes later, I didn’t see my “sister”! I was very sad. Then I went back home. I saw my “sister” on my bed. I was so happy to see her again.

Now, do you know who is my “sister”? OK, let me tell you, she’s my dog---------Lala.
