Rot to death. 自生自灭。 Soon ripe, soon rotten. 早慧早衰。 He is rotton to core. 他坏透顶了。 同义词：decay； decompose：分解； deteriorate：关系恶化（同学们自己查查它的读音） 6、trace： 痕迹 trace the problem. 用作动词，跟踪，找到毛病的根源 I follow your trace I follow wherever you go 二、课文重点难点分析 We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. 1、read of 读到 相似用法：谈到speak of、 talk of、 了解到know of 、听说过hear of 2、知识点：Near East：Mediterranean,South Europe,North Africa Middle East：West Asia Far East：Chian,Japan,Korea 3、where 从句是非限制性从句表原因：我们能够.,因为那里的人们首先学会了书写。 4、补充练习：翻译口语早于书面语出现 翻译一：Oral（spoken）language is earlier than written language. 翻译二：Oral（spoken）language is earlier than written counterpart. 同学们自己查字典学习counterpart 这个词 two things or two people have the same position The only way that they can preserve their history is to recount it as sagas-legends handed down from one generation of story-tellers to another. 5、preserve 保留、保存、腌制（preserved vegetables腌菜） 6、本句结构是：The only way. is to recount.（主、系、表结构） 如果句子中有only ，那么后面跟的表语结构要用 to do sth. 不能用doing sth. 7、handed down 定语legends where are handed down 8、story-teller讲故事的人 fortune-teller、palmreader 算命先生 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. 9、migration：移民 注意几个相关词汇： migrant bird：侯鸟 immigrant：移民（移入） emigrant：移民（移出） 同学们仔细体会这几个词的差异，因为我知道很多同学学英语，打算出国留学、办移民，所以这几个词将来会经常用到。 10、none no body Anthropologists wondered where the remote ancestors of the Polynesian peoples(民族) now living in the Pacific Islands came from. 11、Polynesian peoples：peoples 复数表示民族。 But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. 12、重要句型：if they had any 插入语 表示强调-即便是有 His relatives, if he had (any), never went to visit him when he was hospitalized. So archaeologists have neither history nor legends to help them to find out where the first modern men came from. 13、neither：读音,英音 ai ,美音 i: 还有either 这个词 14、find 与 find out 的区别：find out 指千方百计、费尽周折后找到=explore 15、modern men who were like ourselves Fortunately, however, ancient men made tools of stone. 16、知识点：表示转折的连接词however、but、yet 规律：but、yet 不要加任何标点，only at the beginning of sentence howerver : 放在anywhere you want，加逗号 therefore 和 so 的用法同上，therefore可以放任何地方；so只在句首 17、tool小工具 instrument实验器械 equipment设备 18、may have 表推测 They may also have used wood and skins . 19、peel果皮 leather皮革 hide兽皮 cowhide牛皮 Stone does not decay, and so the tools of long ago have remained when even the bones of the men who made them have disappeared without trace. 20、without (any) trace I run after the thief, but he turned the corner and disappeared without trace.
