Finding fossil man 发现化⽯石⼈人 Why are legends handed down by storytellers useful? 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 world where even now people cannot write. The only way that they can preserve their history is to recount it as sagas -- legends handed down from one generation of storytellers to 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 the 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 them to find out where the first 'modern men' came from. Fortunately, however, ancient men made tools of stone, especiallyflint, because this is easier to shapethan other kinds.They may also have used wood and skins, but these have rottedaway. Stone does not decay, and so thetools of long ago have remained when even the bones of the men who made them have disappearedwithout trace.　读到flint 打⽕火⽯石anthropomorphic ⼈人格化拟1anthropo ⼈人类的让步⼀一⼀一trace backdate back read of read abouta trace of ⼀一些resound u叙述　Polynesian adj.波利利尼⻄西亚(中太平洋之⼀一群岛)的 Indonesia n. 印度尼⻄西亚 我们从书籍中可读到5,000 年年前近东发⽣生的事情，那⾥里里的⼈人最早学会了了写字。

Lesson 2 Spare that spider 不要伤害蜘蛛Why, you may wonder, should spiders be our friends? Because they destroy so many insects, andinsects include some of the greatest enemies of the human race. Insects would make it impossible forus to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for theprotection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects butall of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike someof 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 thedifference almost at a glance, for a spider always 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 censusof the spiders in grass field in the south of England, and he estimated that there were more than2,250,000 in one acre; that is something like 6,000,000 spiders 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 thewildest guess at how many they kill, but they are hungry creatures, not content with only threemealsa day. It has been estimated that the weight of all the insects destroyed by spiders in Britain in one yearwould be greater than the total weight of all the human beings in the country.参考译文你可能会觉得奇怪，蜘蛛怎么会是我们的朋友呢？因为它们能消灭那么多的昆虫，其中包括一些人类的大敌，要不是人类受一些食虫动物的保护，昆虫就会使我们无法在地球上生活下去，昆虫会吞食我们的全部庄稼，杀死我们的成群的牛羊。
