On Sunday morning， the sun is shining. My little brother goes to the zoo with my mother and me. We are very happy.

In the zoo， my little brother is talking， laughing， eating and running. My mother and I are very busy. There are many animals in the zoo. The monkeys are lovely. The lions are fierce(兇猛的). The giraffes are eating leaves quietly（安靜地）. The elephants are playing with their trunks（象鼻）.

“Ah! There are five white cats!” My little brother says.

“Where? Oh no! They are little tigers!” I say.

“No! They are lovely cats!” My brother says.

Oh! How can I explain（解釋） to him? Lovely little tigers are still tigers!
