It was three o’clock. A man was walking down a street in the north of England. He was wearing a dark suit and carrying a suitcase. His name was Terry and lived away from home for twenty years. In fact, he was in prison (监狱) abroad.
Terry was feeling totally depressed because everything in his hometown changed. The park where he used to play was now a car park. The house where he was born disappeared and in its place, ironically (具有讽刺意味地), was a bank. Terry wanted to have a cup of coffee in the old small restaurant where he used to go with his friend after school, but it became a fast food restaurant. He entered it, sat down, and asked for a cup of coffee. Then he felt sadder when he thought of what he saw.
While paying for the coffee, he found an old ticket in his wallet. It was for a pair of shoes he took to be repaired the day before killing someone 20 years ago. The shoe repairer was an old man then, so Terry was sure that he must be dead. But when he turned to the corner of the street, he couldn’t believe his eyes. The shop was still there! And it was the same shoe repairer! He looked about a hundred years old. Terry was so happy! Terry told him that he had lived in Australia for the past twenty years and that he forgot to pick up the shoes before he left England. The shoe repairer disappeared into the back of the shop.

Have you ever wondered how and why a fall leaf changes color? We first have to understand what leaves are and what they do.
Leaves are the world’s food factories. Plants take water from the ground and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖). Glucose is a kind is a kind of sugar. Using it as food, plants get energy and grow. Plants using sunlight to turn water and CO2 into sugar is called photosynthesis(光合作用). ChlorophyII helps photosynthesis. It gives plants their green color.
As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food—making factories.As the green chlorophyII disappears from the leaves, we begin to see yellow and orange leaves. These colors have been in the leaves all the time. We just can’t see them in the summer, because they are covered up by the green chlorophyII.
The bright reds and purples in leaves are made mostly in autumn. In some trees, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color. The brown color of trees is made from waste left in the leaves. It is mixture(混合物) of all these things. It makes the beautiful leaves during autumn.

A．胡萝卜素

It was a cold winter afternoon before Christmas. My parents and I sat on the bench in Washington, D.C. Union Station, waiting for the train. Inside the waiting hall were many people.
A boy sat nearby. His worn jacket, pale face, dirty hands all seemed to tell me that he was homeless.
“He must be cold and hungry. Maybe I should help him,” I said to myself.
Just at that moment, a well-dressed young couple walked towards him.
“Excuse me,” the man bent down. “My wife and I bought two meal boxes but one was enough for us. We hate to waste good food. Can you help us out and put this to use?” he handed the boy a meal box.
The boy thanked them and opened the box with joy and care. Suddenly he stopped. In the direction to which he looked, I saw an old man in rags in a worn sweater, worn trousers and open shoes, entering the hall.
Putting the meal box aside, the boy stood and helped the old to his seat. He took off his jacket and covered it on the old man’s shoulders, saying, “A gentleman brought me this warm meal but I just finished eating. I hate to waste good food. Can you help me out?” He placed the still-warm meal box in the old man’s hands without waiting for an answer.
“Sure, son, but if only you share that sandwich with me. It’s too much for a man at my age. ”
We were all touched. Dad went away and soon returned with cups of hot chocolate and a big pizza. Mum and dad went up to those rags, “Excuse me…”
