Down (1828-1896), British physician] 源自 Mongolian[用于愚痴类病人分类系统的术语，是由英国大夫约翰L．H．道恩(1828-1896年）根据种族的形态而设计得名] 〔protist〕Any of the eukaryotic, unicellular organisms of the former kingdom Protista, which includes protozoans, slime molds, and certain algae. The protists now belong to the kingdom Protoctista, a new classification in most modern taxonomic systems.原生生物：原生生物界中的真核单细胞有机体中的任何一种，包括原生动物、粘菌和某些藻类原生生物现在属于原生生物界，它是大多数现代分类系统中的一个新的类别〔systematics〕A system of classification, as biosystematics.系统学：分类系统，如生物系统学〔larva〕The wordlarva referring to the newly hatched form of insects before they undergo metamorphosis comes from the Latin wordlārva, meaning "evil spirit, demon, devil.”To understand why this should be so,we need to know that the Latin word also was used for a terrifying mask,and it is this sense of the word that has come down to us.In Medieval Latinlarva could mean "mask or visor.” Larva is therefore an appropriate term for that stage of an insect's life during which its final form was still hidden or masked, and New Latinlārva was thus applied by Carolus Linnaeus, the Swedish botanist who originated our system of classifying plants and animals.The wordlarva is first recorded in English in its scientific sense in 1768, although it had been used in its "spirit" sense in 1651 and in a way that foreshadowed the usage by Linnaeus in 1691. larva 一词指昆虫在变形前刚孵化出来的幼虫， 来源于拉丁词larva ， 意为“邪恶的精灵，鬼怪，恶魔”。为了了解为什么，我们需要知道这个拉丁词语还用于指一种令人恐惧的面具，而且正是该词的这一层含义流传了下来。在中世纪的拉丁语中，larva 有“面具或面甲”的意思。 Larva 在形容昆虫成熟之前被隐藏或遮盖的这一段时期的时候，成为一个适合的名称， 这样新拉丁语的larva 一词首先由瑞典植物学家卡罗拉斯里纽斯赋予以上含义， 卡罗拉斯是首创动植物分类系统的第一人。虽然larva 一词在1651年曾经以其“精灵”一层意思被使用并在一定程度上预示了于1691年出现的里纽斯的用法，但是于1768年才以科学术语的形式首先在英语中出现的 |
