One, I have the longest neck and i'm the tallest animal in the world. I like eating leaves on tall trees. There used to be many trees. Now people have cut down too many trees, so I don't have enough leaves to eat. Too, I can fly in the sky just like a kite. I can bring you good luck. These years, I can't find enough trees to live in. They have gone. Three, I am good at running. Leaves and grass are my favourite, but they have almost disappeared around me. For many people love me, but there is less bamboo now, so I have been hungry for months. Please help me. Five, I am large and live in the sea. Human polluted the sea, so I don't live happily. Six, i'm small and live in the river. The water was clean many years ago, but IT is too dirty for me to live in. Now i'm in danger. 康康，jane, maria and Michael are planning the picnic for sunday. 康康，where shall we go? What about the west tale? I went there two years ago. I was a beautiful place.
