When they drove down, over the River Thames and into the city centre, they found it was not so peaceful after all! The main streets were packed with traffic: cars, lorries, coaches full of tourists and the bicycles which the students use to get about. But as soon as they had managed to park the car and get away from the roaring traffic, they discovered a completely different world. Narrow cobbled (铺圆石子的) streets which had hardly changed since the Middle Ages ran between the high college walls of grey or yellow stone. Inside the great double gates of each college they found quiet squares of grass, the library, the dining-hall and the rooms where the students and teachers live. Many colleges had the most beautiful gardens where one could sit and read, talk work or dream.
Most of the students, or undergraduates, wore informal clothes: sports coats, or pullovers, and slacks. But some of them were wearing their black gowns. George explained that they had to wear these when going to lectures or to their weekly meeting with their tutor, or teacher. Tom and Anne were very surprised to see a few young men dressed in formal black suits, with ties ,gowns and scholars' caps. Anne asked whatever they were doing, wearing evening dress in the morning ! George laughed and said that this was the official dress for taking examinations, many of which were held in June.

A.see the spires and the domes

Color does influence our moods (情绪)― there is no doubt about it.A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress bri ngs warmth and cheer to the saddest winter day.On the other hand, black is depressing.A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area — until it was repainted green.The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

Prehistoric (史前的)had little choice in what he ate. He ate what he could find: roots, eggs, fruits and the meat of smallanimals. Early man had no way to control his food supply. If there was no rain, or the weather was too hot or too cold,plants would not grow, and he would have little or no food. When he ate all the food in one place, he had to move to anotherregion for food.
Man’s life changed when he learned to grow plants and to raise animals. He also learned to use fire to prepare his food. Later, he learned to make tools and weapons, and to make containers to store his food. Man could now live in one place andproduce his own food. So civilization (文明)began. Great civilizations slowly developed in regions where food wasplentiful — along the Nile River in Egypt, and by the Yellow River in China.
The kinds of plants which are raised by man are different in each geographical region. In the colder regions very fewplants can be grown; in the warmer parts of the world great varieties of plants are found. In Asia, rice has become the mostimportant crop. In North America, the most important grains are wheat and com. In Europe and North Africa, wheat is themain crop. In the tropical (热带的)regions of the world,many kinds of fruit grow naturally or arc planted by man.
With the development of methods of keeping food fresh, it became possible to send most food products from one partof the world to another. Today foods are kept fresh in many ways and sent all over the world. Man no longer depends on thefood he grows in his own area only.
