The duck and the cat
A brown duck meets a sad cat and asks him, "What's the matter with you? Can I help you?" The cat says nothing but leaves.

The duck catches up with(追上) the cat and says, "Please tell me, OK? I can do a lot of things for you." "Oh, no. You can't." The cat shakes his head and goes away.
The duck keeps up with(跟着) the cat and asks him again. The cat cries, "I want to give some flowers to my mother on Mother's Day. But I can't find flowers." The duck says happily, "I can help you."
The duck points to the other side of the river and says, "Look there! There are many beautiful flowers." So the cat climbs up a tree, "Wow, how beautiful!"
"But I can't swim. How can I get there?" The cat is worried. The duck says, "Don't worry. I can swim. You can just sit on my back."
In the river, the duck tells the cat, "If(如果) we help each other, we can do many things."
