基本释义 Primitive means belonging to a society in which people live in a very simple way, usually without industries or a writing system.Unlike their more graceful cousins, the primitive frogs kept their back legs straight out after they jumped. So they don’t land on their feet. Instead, they do an ungainly belly flop, and then struggle to get to their feet and jump again.与它们优雅的表亲不同的是，原始的青蛙在跳跃后后腿保持直立。这样它们就不用双脚落地了。相反，它们做了一个笨拙的腹部扑腾，然后挣扎着站起来，再次跳跃。
单词primitive里的词根prim来自拉丁语primus，表示“最初的，主要的”，所以，英语里包含prim的单词，多与此相关。例如：prime /praɪm/ adj. 主要的，最好的 primal /ˈpraɪml/ adj. 原始的，主要的 primate /ˈpraɪmeɪt/ n. 灵长目动物 primary /ˈpraɪməri/ adj. 最初的，根本的 adj. 早期的，远古的
In the mid-1940s, labour-free production was still a fantasy because there were no computers, and electronic devices were very primitive.在20世纪40年代中期，无人化生产仍然是一个幻想，因为当时没有电脑，电子设备也非常原始。
