The Great Fire of London started in the very early hours of September 2, 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. Over one hundred people became homeless, but only a few lost their lives .

　　The fire started on Sunday morning in the house of the King’s baker（面包师）in Pudding Lane. The baker, with his wife and family, was able to get out through a window into the roof. A strong wind blew the fire from the bakery（面包房）into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.

　　By eight o’clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul’s and the Guildhall among them .

　　Samuel Pepys , the famous writer, writer about the fire, “People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat .”

　　The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path（路径） of the fire.With nothing left to burn, the fire became weak and finally died out.

　　After the fire, Christopher Wren, the architect(建筑师), wanted a city with wider streets and fine new houses of stone．In fact, the streets are still narrow, but he did build more than fifty churches, among which was the new St Paul’s

　　The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.

Ask three people to look out the same window at a busy street comer and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives(察觉) something different about it. 

Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception(感知) is the minds’ interpretation of what the senses — in this case our eyes — tell us.

Many psychologists(心理学家)today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.

A. in our eyes             B. only when we think very hard about something
