動物拉丁文學名（二名法 binomial nomenclature）比各地俗名好

動物拉丁文學名（二名法 binomial nomenclature）比各地俗名好

● 字源

「binomial」由拉丁文 bi-（二）與 nomen（名）組合而成，指以「屬名＋種小名」兩個詞標示物種的命名法。「nomenclature」源自拉丁文 nomenclatura（命名），一般認為二名法由十八世紀瑞典博物學家林奈（Linnaeus）普及，成為全球通用的物種命名依據。

● 例句

Were it not for the binomial system, which Linnaeus popularized in the eighteenth century and which gives every organism a Latin name that scientists, whose native languages may share no vocabulary, can recognize at once, zoologists would never confirm that the Korean tiger, the Northeast China tiger, and the Siberian tiger, which local communities have long treated as different animals, are one and the same Panthera tigris altaica, just as the cougar, the puma, and the mountain lion, names that vary from region to region, all denote Puma concolor, since common names, as taxonomists have repeatedly warned, mislead more often than they clarify.

● 排列為比較容易閱讀的方式

Were it not for the binomial system,

which Linnaeus popularized in the eighteenth century

and which gives every organism a Latin name

that scientists,

whose native languages may share no vocabulary,

can recognize at once,

zoologists would never confirm

that the Korean tiger, the Northeast China tiger, and the Siberian tiger,

which local communities have long treated as different animals,

are one and the same Panthera tigris altaica,

just as the cougar, the puma, and the mountain lion,

names that vary from region to region,

all denote Puma concolor,

since common names,

as taxonomists have repeatedly warned,

mislead more often than they clarify.

● 分解為原初的短小句

If it were not for the binomial system, zoologists would never confirm the matter.（Were 置於句首，省略 if 而倒裝；主句主詞 zoologists 要等到很後面才出現。）

Linnaeus popularized the binomial system in the eighteenth century.（which 引導之關係子句。）

The binomial system gives every organism a Latin name.（第二個 which，與前一個並列。）

Scientists can recognize the name at once.（that 引導之關係子句，that 在子句中作 recognize 之受詞。）

Scientists' native languages may share no vocabulary.（whose 引導之插入子句。）

The Korean tiger, the Northeast China tiger, and the Siberian tiger are one and the same Panthera tigris altaica.（that 引導之名詞子句，作 confirm 之受詞。）

Local communities have long treated the three tigers as different animals.（which 引導之非限定性關係子句。）

The cougar, the puma, and the mountain lion all denote Puma concolor.（just as 引導之比較子句，與老虎的例子對照。）

The names vary from region to region.（names that vary 為同位語，補充說明三個俗名。）

Common names mislead more often than they clarify.（since 引導之原因子句。）

Taxonomists have repeatedly warned this.（as 引導之插入子句，as 代替後面整個內容。）

● 文法解析

Were it not for 倒裝（Were it not for + 名詞, 主詞 + would + 原形動詞）：

這是假設語氣的倒裝，等於 If it were not for。主句要到 zoologists would never confirm 才出現，前面已經塞入約 35 個字的修飾。讀者容易把 Were 誤認為一般疑問句，須先辨認它是虛擬語氣。

兩個 which 並列（which Linnaeus popularized ... and which gives ...）：

兩個關係子句共同修飾 the binomial system，以 and which 連接。第二個 which 的動詞 gives 離先行詞很遠，須回頭確認主詞。

whose 插入於 that 子句中（a Latin name that scientists, whose native languages ..., can recognize）：

that 的關係子句主詞 scientists 與動詞 can recognize 之間，被 whose 子句截斷，形成插入中的插入。

that 名詞子句內的同位並列（confirm that the Korean tiger, the Northeast China tiger, and the Siberian tiger ... are ...）：

主詞為三個並列名詞，中間又插入 which 非限定子句，使動詞 are 遲遲不出現。複數主詞對應 are，須從三個名詞一路數過來。

just as 比較子句與同位語（just as the cougar, ... names that vary ..., all denote ...）：

just as 引入與老虎對照的第二組例子。names that vary from region to region 為同位語，說明前面三個俗名。all 位於主詞之後、動詞之前，為副詞用法。

since 子句與 as 準關係代名詞（since common names, as taxonomists have repeatedly warned, mislead ...）：

as 子句插在主詞 common names 與動詞 mislead 之間，as 代替後面整個內容。末尾 more often than they clarify 為比較結構。

● 參考譯文

若非有林奈於十八世紀推廣、為每種生物賦予一個拉丁名稱的二名法（這些名稱即使母語毫無共通詞彙的科學家，也能立刻辨認），動物學家根本無法確認：朝鮮虎、東北虎與西伯利亞虎（各地居民長期視之為不同的動物）其實是同一個 Panthera tigris altaica，正如美洲獅的各種俗名（cougar、puma、mountain lion，各地說法不一）全都指 Puma concolor，因為如分類學家一再警告，俗名往往誤導多於釐清。

● 補充說明

句型亮點與文法變化：

Were it not for 倒裝： 前幾篇已用過 No sooner、Seldom、Little、Only after、Not only、Not until、Hardly 等否定副詞倒裝，本篇改用省略 if 的虛擬語氣倒裝，結構不同，主句同樣被推遲出現。

不使用分號： 全句僅以 which、that、whose、just as、since、as 等連接詞與關係詞推進，單一主幹貫穿到底。

雙組例子對照： 老虎（三個俗名對一個學名）與美洲獅（三個俗名對一個學名）以 just as 連接，使「學名統整俗名」的論點更有說服力。

多重插入： binomial system 與 zoologists 之間、scientists 與 can recognize 之間、three tigers 與 are 之間、common names 與 mislead 之間，皆有插入成分。

更多學名例子（可替換或延伸使用）：

虎鯨、殺人鯨（killer whale）、逆戟鯨，學名皆為 Orcinus orca。

朝鮮虎、東北虎、西伯利亞虎、阿穆爾虎（Amur tiger），都是 Panthera tigris altaica。

馬來熊（Helarctos malayanus）與台灣黑熊（Ursus thibetanus formosanus）不是同一種，前者為獨立物種，後者為亞洲黑熊的亞種，可作為「同名為熊卻不同種」的對照例。

核心學術字彙與文法重點總結：

關鍵字詞： Binomial nomenclature（二名法）、Taxonomist（分類學家）、Vernacular／common name（俗名）、Subspecies（亞種）、Denote（指稱）、Organism（生物體）、Popularize（普及）、Clarify（釐清）。

文法重點： Were it not for 倒裝、並列 which 子句、whose 插入、that 名詞子句、just as 比較子句、同位語、as 準關係代名詞、since 原因子句。

一點小提醒： 東北虎、朝鮮虎、西伯利亞虎皆為同一亞種，分類上通稱阿爾泰虎，學名 Panthera tigris altaica；嚴格說「虎」這個物種是 Panthera tigris，altaica 是其亞種，例句為求簡潔略去此區別。例句實際約 103 個英文單字。參考譯文為求順暢，已調整部分分句順序。
