My most unforgettable school picnic was going to the Wetland Park. There were different types of birds. I was very surprised to have seen a crocodile that I had never seen. The fresh air there made me feeling comfortable. I was happy because I learned the different types of birds. I am looking for a chance to visit/go the Wetland Park again so that I can learn more.

It/this is a unforgettable memory in my life. I had a school picnic in wonderland, when I was a little kid, I don't even know what is love until I met her. She has golden brown hair, snow white skin and breathless face. She sings a song like Cinderella, a fairy tale dream girl. The attention of everyone has been attracted but finally do not know who the girl is. I am regretting of myself and wish to see her once again. However, I am so happy I used to saw a perfect one in world, in my mind.
