— OK.I can ______________ it, Mrs. Wang.

    Several months ago, a traffic policeman in Moscow led(牵) a horse walking on the street. The horse is like a zebra. The police wanted to give the drivers a lesson. And he also wanted to tell the students safety is very important. The traffic policeman led the zebra to several different places handing out the flyers (发传单) to the passing drivers.

    The roads in Russia are very dangerous but drivers still don't give way to the walking people. Every year, many people are killed or injured in road accidents. Nearly half of all traffic accidents were caused by cars hitting pedestrians(行人), and a third of those happened on crossings.

    The traffic policeman wanted to give people a lesson, but the animal rights people were very angry with the police for "treating animals like garbage".

    There was a robin's nest outside our kitchen window. The mother robin sat in the nest all day long. One day when I was watching, the mother bird flew away. I saw four blue eggs. I watched and watched. Pretty soon the eggs started to move. I watched until the eggs started to crack. Finally, I saw four baby birds. Soon the mother bird came back. Then the mother robin put worms in their mouths.

    Every day I watched the baby birds and their mother. Pretty soon the babies were fat and big. So there was no room for the mother robin. Then one morning the nest was gone. Mum and I went outside and looked around. The nest was on the ground. It was still in one piece. But there were no robins anywhere. Just then, we heard the robin's singing. We looked up, just in time to see five robins fly away.

    Once upon a time, a hippo(河马) lived in a river next to a big tree.

    One day, a bird came and nested(筑巢) in the tree. The songs of the bird filled the hippo with so much envy (羡慕) that he couldn't think of anything else. Every day he would think why he wasn't born to be a bird even though the bird told him many times he was so lucky to be so big and such a good swimmer.

    Finally, the hippo made up his mind that he would come out of the river, climb the tree, and start singing. However, when he tried to climb the tree, it was very clear that the hippo didn't have wings, nor claws to climb with.

    Realizing that he would never climb up the tree, he angrily hit the tree until it came crashing to the ground. Then he stepped onto the leaves of the fallen tree, and began singing.

    Unfortunately, hippos can't sing, either. All that came from his mouth were terrible noises, and when the other animals heard these, they all came around to make fun of the hippo.

    He was too ashamed of this. He also felt bad about having knocked the tree over. He used all his strength to raise the tree back up again, and looked it after until it completely recovered(康复).
