lar.val
adj.（形容詞）
<注釋>The wordlarva referring to the newly hatched form of insects before they undergo metamorphosis comes from the Latin wordl3rva, 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 Latinl3rva 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 7'8, although it had been used in its .spirit. sense in '5 and in a way that foreshadowed the usage by Linnaeus in '9.
larva 一詞指昆蟲在變形前剛孵化出來的幼蟲， 來源于拉丁詞larva ， 意為.邪惡的精靈，鬼怪，惡魔.。為了了解為什么，我們需要知道這個拉丁詞語還用于指一種令人恐懼的面具，而且正是該詞的這一層含義流傳了下來。在中世紀的拉丁語中，larva 有.面具或面甲.的意思。 Larva 在形容昆蟲成熟之前被隱藏或遮蓋的這一段時期的時候，成為一個適合的名稱， 這樣現(xiàn)代拉丁語的larva 一詞首先由瑞典植物學家卡羅拉斯里紐斯賦予以上含義， 卡羅拉斯是首創(chuàng)動植物分類系統(tǒng)的第一人。雖然larva 一詞在'5年曾經(jīng)以其.精靈.一層意思被使用并在一定程度上預示了于'9年出現(xiàn)的里紐斯的用法，但是于7'8年才以科學術語的形式首先在英語中出現(xiàn)的
