If a man lives in a warm climate, clothing is not absolutely necessa

2、ry. However, man cannot live without food, and, he has little chance of survival without shelter. Mankind needs shelter to protect him from the weather, wild animals, insects, and his enemies.Long before man learned how to build houses, he looked for natural shelters, as the animals did. He found th

3、at he could protect himself by climbing up into trees or by crouching under the over-hanging edges of cliffs, or by crawling into caves. The first shelters or homes actually built by man were very simple. For his building materials, he used what he could find easily around him: rocks, tree branches,

4、 dried grasses, animal skins. It was a long time, however, before man began to build permanent shelters because, until man learned to farm, he lived by hunting. And, in order to follow game, he had to be able to move from one hunting ground to another. Thus, the first man-made shelters were those th

5、at could be easily transported.The first permanent shelters were probably built twenty to forty thousand years ago by fish eating people who lived in one place as long as the fish supply lasted. Fish-eaters could stay in one place for several years. However, once man learned to farm, he could live l

6、onger in one place. Thus, he was able to build a permanent home. Once again, he built his home with the materials he found at hand. In Egypt, for example, wood was scarce, so most houses were built of bricks made of dried mud, with a roof supported by palm tree minks.When the Norsemen came from Scan

7、dinavia to northern Europe, they found many forests, so they built homes with a framework of heavy tree thinks and they filled the space between the trunks with clay. The Eskimos, on the other hand, lived in a land where there was little or no wood. They learned to adapt their homes perfectly to the

8、ir surroundings. In the winter time, when everything was covered with snow and ice, the Eskimos built their homes with blocks of ice. When the warm weather came and melted the ice, the Eskimos lived in a tent made of animal skins.The weather is mans worst natural enemy. He has to protect himself fro

9、m extremes of heat and cold and from storms, wind and rain.Where the weather is hot and dry, the house is generally made of clay brick. The windows are small and high up, so that the heat stays outside. There is often a flat roof, where people can find a cool place to sleep. In hot, humid areas, on

10、the other hand, people need to be protected from the rain, as well as the heat. In such places, houses are built with wide, overhanging roofs, balconies or verandas (走廊).Where there are torrential rains, houses are either built on piles to keep them off the ground, or they have steep thatched (草屋顶的)

11、 roofs to drain off the rain. People living in the Congo River region have found that steep, heavily-thatched roofs drain off the jungle rains more quickly. Other people in Africa have found that a roof of broad leaves sheds rain quickly.In Borneo, houses are built on high posts to protect people fr

12、om dampness. And there are tribes in Malaya who build their homes in the forked branches of trees, and climb up to their houses on bamboo ladders.In northern countries, people build houses to protect themselves from cold and snow. Their houses are built of sturdy materials, and the roofs are steep,

13、so that the snow will slide off. There are also overhanging eaves (屋檐) to keep the snow from piling up next to the house. And, in northern Siberia, where snowfall is extremely heavy, the roofs even have a funnel-shaped (漏半状的) platform to protect the chimneys from drifting snow.Protection from danger

14、 has also influenced the type of house man builds. When enemies threatened him, man made his house as inaccessible as possible. The tree-dwellers of the Philippines protect themselves by living high above the ground. When danger threatens, they remove the ladders leading to their homes. The cliff dw

15、ellers of the American Southwest built their homes high up on the sides of cliffs, where access was very difficult.Nomad (游牧的) tribes must move from place to place, taking care of flocks of sheep that are always in need of fresh grass. Their houses must be simple and easy to transport. The nomads of

16、 central Asia have developed a house made of a framework of poles covered with felt (毛毡). The house is round because the framework is curved. The poles are fastened together at the top with a wooden ring, and there is a hole at the top to let the smoke out.In Europe there are very few wooden houses

17、being built today. This is partly because wood is no longer as plentiful as it once was, and partly because wooden houses are quite inflammable (易燃的). On the other hand, there are many wooden houses in America. This is because the first settlers wanted to build houses quickly and inexpensively. Sinc

18、e the country was covered in many places with forests, some trees had to be cut down to make room for houses.Houses in many cities used to be made of wood. However, since the houses were very close together, fire could easily spread from one house to another. There were disastrous fires in some citi

19、es, such as the great fire of London in 1666. When the burned-out cities were rebuilt, wood was still used for the frames and the roofs, but stones or bricks were used for walls.There are so many people living in some cities that it is often very difficult to find a place to live, and if one does fi

20、nd a place it is often too small. And many of the houses are too old and uncomfortable. Just as in prehistoric times, finding a good place to live continues to be one of mans most urgent problems.（分数：70.00）(1).What does the passage focus on?（分数：7.00）A.Mans three basic needs.B.Development of roofs.C.
