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，腫塊)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.
【小題1】What kind of story is talked about in this programme?
A．Romantic stories.B．Mysteries.C．Horror stories.D．Comedies.
【小題2】Which sentence is TRUE about the two green children?
A．They both enjoyed a long and happy life.
B．The girl’s eyes and skin were green all her life.
C．At first they spoke the same language as people in the small village did.
D．Maybe they hadn’t eaten enough for long before they reached the village.
【小題3】What does Nessie look like according to some witnesses? 

【小題4】What can we learn from the second story?
A．Scientists are still not sure whether there is a monster or not in Loch Ness.
B．Loch Ness is very deep and warm lake in Scotland.

We spend hours, days and years of our lives in school. Imagine(想象) you could design(設計) your dream school, what would it be like? What would you be doing? We wanted to find out what teenagers around the world thought. Here is what they said:

Richard from the USA: My dream school would have a big swimming pool and two soccer fields. It would also have a cinema, a gym and a shopping centre. My school has none of these, and I think there should be more pleasant things for students to do while they are studying.

Sonia from Italy: I’d like a room where we can relax and play computer games. I’d also like to have a music room. I think there should be a place for everyone to go and relax after class.

Wu from Beijing: I think it would be great to have another day off (休息日) every week, besides the weekend. If that day was a Friday or a Monday, we would have a long weekend every week. What fun! I also think school should start later, at about 10 o’clock, and finish earlier.
