The clockwork(機械) radio is the only radio that doesn’t need batteries(電池) or electricity. It is powered(提供動力) by turning the handle(手柄) for a minute.

The clockwork radio was invented in 1991 by Trevor Bayliss, a British inventor. Trevor had the idea while he was listening to some news about Africa on the radio. It was reported that Africans were dying of Aids(艾滋病) and there was no easy way to send them some information about the disease.

But no one would help Trevor develop his idea for a new kind of radio. Finally, in 1993, a TV program showed his invention, and afterwards, a South African businessman heard of Trevor’s clever idea and contacted(聯(lián)系) him.The first clockwork radios were made in South Africa in 1995.

Since then, the radios have been a great success. Trevor has been given many prizes.

Trevor has hung a letter written by another engineer on the wall in his house. The engineer explained in the letter why he thought Trevor’s idea for a clockwork radio couldn’t possibly work!

以下是某學校通過校長意見箱收集到的一些學生的意見和建議。請仔細閱讀,然后按信息卡的要求填入相關(guān)信息。

Zhang Hongying, girl,15

I want to make our lunch time longer. At the moment, the lunch time is short. Most of my classmates would like to do their homework during this time. But if they don't get a good rest, they won't have enough energy for the afternoon. So I would like to have more time to take a nap after lunch. That way, we'll learn better in the afternoon.

Zhao Pengran, girl,15

I would like to have more chances to talk in English. Now, the English classes are not enough for us to practice speaking English. I think we'd better have one morning a week at least to have spoken English lessons in order to improve our English.

Zhou Jiancheng, boy,15

My idea would be to have more fashionable school uniforms. If I were the headmaster, I would ask the students to design the uniforms themselves. We could have a contest among student designers. Then, we could ask others to choose their favorites. This way, we'll be able to wear what we like best. How nice it would be for us young people!

When you wave to a friend, you are using body language. When you smile at someone you mean to be friendly. When you put one finger in front of your mouth, you mean “be quiet”. Yet, people in different countries may use different body languages.

Once an Englishman was in Italy. He could speak little Italian. One day while he was walking in the street, he felt hungry and went into a restaurant. When the waiter came, the Englishman opened his mouth, put his fingers into it and took them out again and moved his lips. In this way, he meant to say, “Bring me something to eat.” But the waiter brought him a lot of things to drink, first tea, then coffee and then milk, but no food.

The Englishman was sorry because he was not able to tell the waiter he was hungry. He was ready to leave the restaurant when another man came in. The man put his hands on his stomach, and this body language was good enough for the waiter. In a few minutes, the waiter brought him a large plate of bread and meat.

Finally the Englishman had his meal in the same way.

My mother only had one eye. I never wanted her to show up in my school. One day during my primary school, I was terribly ill and my mother came. “Your mother only has one eye!” Some of my classmates yelled(喊叫). I wished my mother would just disappear(消失). I shouted at her, taking no notice of the sad look on her face. My mother just handed me some medicine and left without saying anything.

At that time, I didn’t think I had hurt her feelings. That night I saw my mother crying in her room. Even so, I hated her tears from one eye. I made a decision: I must study hard and leave my mother.

Years later my dream came true. I was quite successful. I never thought of going back to see my “ugly” mother until one day I got a letter.

“My son I’m sorry I only have one eye. When you were little, you had an accident and lost your eye. I couldn’t stand watching you live with only one eye. So I gave mine to you. I never regretted doing it because I love you.” I cried out aloud. Only then did I realize how beautiful my mother’s eye was!
