    Once there was a huge apple tree. A little boy loved to come and play around it every day. He loved the tree and the tree loved to1with him.

    Time went by --- the boy had grown up and he2 played around the tree. One day, the boy came back to the tree and he looked3“Come and play with me,” the tree asked the boy. “I'm no longer a kid. I4play around the tree any more.”the boy replied,“I want toys. I need 5to buy them.” “Sorry, I don't have money. But you can 6 all my apples and sell them. So, you will have money.” The boy picked all the apples on the tree and left7. The boy never came back after he picked the apples. The tree was sad.

    After that the boy returned and asked the tree for help again and again. First, he asked the tree for a house, and the tree gave the boy all its branches. Second, he told the tree he needed a 8to go sailing, the tree offered its trunk9 the boy returned after he left for so many years. “Sorry, my boy. But I don't have anything for you any more. The only thing left is my dying root（根）,” the tree said with tears.

    “Good! Old tree root is the10 place to lean on and rest”. The boy sat down and the tree was glad and smiled with tears.

We may think that the boy is15to the tree but that's how all of us are treating our parents.

Good evening, ladies and gentlemen. Welcome to the nine o’clock Mystery Hour. Today we’ll show you two British stories. We hope you’ll enjoy them.
About 900 years ago two green children arrived in a small village in south England. Their eyes and skin were green and they spoke a strange language. They were very tired and weak, so the people of the village looked after them. The boy died a year later, but the girl grew strong and lived the rest of her life there. And her skin colour turned back to normal day by day. Scientists say that sometimes of people don’t have enough food to eat for a long time, their skin goes very pale and can even turn green.
Loch Ness is the largest lake in Scotland. It’s a very deep and cold lake. For hundreds of years, people have talked about a monster(怪物) called Nessie which lives in the lake. About seventy years ago, two people saw something moving in the lake. They said that the animal was playing and rolling around in the water. Since then many people say they have seen the monster. Their descriptions are always the same. It looks like a dinosaur, with a very long neck and a small head. It has a big bump(包，肿块)on its back. People have tried to photograph the animal, but the pictures have not been very clear. Scientists don’t know whether there is a monster or not. Some say it may be a whale or a very large fish. Some think it’s a snake. Others say there’s nothing at all— nothing but people’s imagination. Maybe we’ll never know what’s in Loch Ness.
