The development of early toolmaking techniques marked a significant milestone in human history.Evidence suggests that our ancestors began T crafting tools over 2.6 million years ago during the Stone Age. These tools, primarily made from stone, were essential for survival, aiding in hunting, food preparation, and protection.





Some of the earliest tools were simple, unrefined implements known as Oldowan tools, named after the Olduvai Gorge in Tanzania where they were first discovered. These early tools were often made by chipping away at stone. However, not all early tools were rudimentary . By around 1.76 million years humans had advanced physiologically and began creating more sophisticated tools called Acheulean handaxes. These tools showcased remarkable craftsmanship with their symmetrical shapes and razor-sharp edges.





The evolution from Oldowan to Acheulean tools indicates significant cognitive development and manual dexterity.This advancement in toolmaking likely contributed to social changes, enabling early humans to hunt more effectively and process food more efficiently.Recent discoveries have revealed even older tools, suggesting that toolmaking might have originated earlier than previously thought.Researchers continue to explore archaeological sites to uncover more about the origins and evolution of these ancient technologies.

"1. 题干:文中 “rudimentary” 一词的意思最接近哪一项?(原文:The word ""rudimentary"" in the passage is closest in meaning to) 2. 分析 题目类型:词汇题 解题策略:需结合该词所在的上下文(尤其是对比关系),推断其含义,再匹配选项。 3. 定位信息理解 原文定位:“Some of the earliest tools were simple, unrefined implements... However, not all early tools were rudimentary. By around 1.76 million years humans... began creating more sophisticated tools...” 信息理解:前文描述早期工具是 “simple, unrefined(简单、未精制的)”,随后用 “However” 转折,对比 “rudimentary” 与 “more sophisticated(更复杂精密的)”,因此 “rudimentary” 对应 “简单、基础” 的含义。 4. 分析选项 (A) natural(自然的) 分析:与 “rudimentary” 的 “简单基础” 含义无关,排除。 (B) carved(雕刻的) 分析:这是工具的制作方式,并非 “rudimentary” 的含义,排除。 (C) basic(基础的) 分析:与上下文 “simple, unrefined” 及 “与 sophisticated 对比” 的逻辑一致,此为正确答案。 (D) fragile(易碎的) 分析:原文未提及工具的 “易碎性”,排除。"
