1、新概念英语第四册1Lesson 1 Finding fossil man 发现化石人发现化石人 We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the word where even now people cannot write. The only way that they can preserve their history is to recount it as sa
2、gas - legends handed down from one generation of another. These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in th
3、e Pacific Islands came from. The sagas of these people explain that some of them came from Indonesia about 2,000 years ago. But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help
4、 them to find out where the first modern men came from. Fortunately, however, ancient men made tools of stone, especially flint, because this is easier to shape than other kinds. They may also have used wood and skins, but these have rotted away. Stone does not decay, and so the tools of long ago ha
5、ve remained when even the bones of the men who made them have disappeared without trace. ROBIN PLACE Finding fossil man Lesson 2 Spare that spider 不要伤害蜘蛛不要伤害蜘蛛 Why, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects include some of the greatest enemies o
6、f the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects but all of them put together kill o
7、nly a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never do the harm to us or our belongings. Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always
8、has eight legs and insect never more than six. How many spiders are engaged in this work no our behalf? One authority on spiders made a census of the spiders in grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like 6,000,000 spi
9、ders of different kinds on a football pitch. Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of al
10、l the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country. T. H. GILLESPLE Spare that spider from The Listener Lesson 3 Matterhorn man 马特霍恩山区人马特霍恩山区人 Modern alpinists try to climb mountains by a route which will give them
11、good sport, and the 新概念英语第四册2more difficult it is, the more highly it is regarded. In the pioneering days, however, this was not the case at all. The early climbers were looking for the easiest way to the top, because the summit was the prize they sought, especially if it and never been attained bef
12、ore. It is true that during their explorations they often faced difficulties and dangers of the most perilous nature, equipped in a manner with would make a modern climber shudder at the thought, but they did not go out of their way to court such excitement. They had a single aim, a solitary goal -
13、the top! It is hard for us to realize nowadays how difficult it was for the pioneers. Except for one or two places such as Zermatt and Chamonix, which had rapidly become popular, Alpine village tended to be impoverished settlements cut off from civilization by the high mountains. Such inns as there
14、were generally dirty and flea-ridden; the food simply local cheese accompanied by bread often twelve months old, all washed down with coarse wine. Often a valley boasted no inn at all, and climbers found shelter wherever they could - sometimes with the local priest (who was usually as poor as his pa
15、rishioners), sometimes with shepherds or cheese-makers. Invariably the background was the same: dirt and poverty, and very uncomfortable. For men accustomed to eating seven-course dinners and sleeping between fine linen sheets at home, the change to the Alps must have very hard indeed. WALTER UNSWOR

One case concerns and eleven-year-old schoolgirl, Vera Petrova, who has normal vision but who can also perceive things with different parts of her skin, and through solid walls.
