2、oof over our Heads Man has three basic needs: food, clothing, and shelter. If a man lives in a warm climate, clothing is not absolutely necessary. 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

3、 animals, insects, and his enemies. Long before man learned how to build houses, he looked for natural shelters, as the animals did. He found that 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

4、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, 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 hunt

5、ing. 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 that 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 p

6、lace 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 longer 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,

7、wood was scarce, so most houses were built of bricks made of dried mud, with a roof supported by palm tree trunks. When the Norsemen came from Scandinavia to northern Europe, they found many forests, so they built homes with a framework of heavy tree trunks and they filled the space between the trun

8、ks 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 their 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 weath

9、er came and melted the ice, the Eskimos lived in a tent made of animal skins. The weather is man s worst natural enemy. He has to protect himself from 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 ar

10、e small and high up, so that the heat stays outside. There is often a fiat roof, where people can find a cool place to sleep. In hot, humid areas, on 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, balconi

11、es 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 (茅草屋顶的) 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

12、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 from 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.

13、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, 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

14、, where snowfall is extremely heavy, the roofs even have a funnel-shaped (漏斗状的) platform to protect the chimneys from drifting snow. Protection from danger has also influenced the type of house man builds. When. enemies threatened him, man made his house as inaccessible as possible. The tree-dweller

15、s of the Philippines protect themselves by living high above the ground. When danger threatens, they remove the ladders leading to their homes. The cliff dwellers 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

16、 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 nom ads of 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.

17、 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 being built today. This is partly because wood is no longer as plentiful as it once was, and partly because wooden houses are quite inflamma

18、ble (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. Since 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

19、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 cities, 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, bu

20、t 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 find 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

21、 to live continues to be one of man s most urgent problems. （分数：71.00）(1).This passage mainly describes different kinds of roofs that man has built for his house. （分数：7.10）A.YB.NC.NG(2).The first shelters or homes actually built by man were only made of branches of trees. （分数：7.10）A.YB.NC.NG(3).The

When people take anything too seriously, they put on blinders, which cause them to miss the important (36) 1 of what is going on aroun

34、d them. They develop “tunnel vision,“ which limits and (37) 2their perception of (38) 3. Education is too important to be limited by those who have (39) 4to wear blinders and develop tunnel vision. I believe the accountability movement has (40) 5many educators to take education too seriously. When w

35、e take education too seriously, we put (41) 6tests scores above children, we put lesson plans above teachers, and we put on our blinders, only to see a (42) 7small segment of the childthat segment that can be (43) 8easily than looking at the child as a whole. (44) 9. How can we take off our blinders

36、? How can we eliminate tunnel vision to see the whole child? How can we not take everything so seriously? My recommendation is simply to laugh, teach and laugh. Psychologists have long believed that negative motions cause negative chemical changes in the body. We know the opposite is also true. (45)

37、 10. Laughter actually relaxes the muscles, allows the heartbeat, and lowers blood pressure. Laughter stirs the inside and gets the endocrine system moving, which can be quite beneficial in alleviating disease.

39、2025. The U. N. expects the total population to stabilize (稳定) at Il. 6 billion sometime later in the 2000 s. More than ninety percent of the population growth will occur in developing countries. Eighteen of the world s twenty largest cities will be in these lands as the number of urban-dwellers (城市

40、居民) swells from roughly two billion to 5.1 billion. The Unites States and Europe, which in 1950 accounted for twenty-two percent of the world s population, will be home to less than nine percent of its people in 2025. By contrast, Africa s share of the total will climb from nine percent in 1950 to n

41、early twenty percent by 2015. Ethiopia should double in size to almost 100 million people. In about the same time period, India will overtake China as the worlds most populous country.
