# 2.1. 元音Vowels
英文总计 6 个基础元音,分别是 `ʌ``e``ə``ɪ``ʊ``ɒ` —— 这 6 个短元音就好像是 “根” 一样。剩下的 14 个元音要么是它们略有变化的更长版本,即,长元音 —— `ɑː, æ, əː, iː, uː, ɔː`要么是它们的组合版本,即,双元音 —— `aɪ, eɪ, ɔɪ, aʊ, oʊ, eə, ɪə, ʊə`
英文总计 6 个基础元音,分别是 `ʌ``e``ə``ɪ``ʊ``ɒ` —— 这 6 个短元音就好像是 “根” 一样。剩下的十几个元音要么是它们略有变化的更长版本,即,长元音 —— `ɑː, æ, əː, iː, uː, ɔː`要么是它们的组合版本,即,双元音 —— `aɪ, eɪ, ɔɪ, aʊ, oʊ, eə, ɪə, ʊə`
In English, there are 6 basic vowels: `ʌ`, `e`, `ə`, `ɪ`, `ʊ`, and `ɒ`. Think of these 6 short vowels like the *roots* of a tree. The remaining 16 vowels are either slightly modified, longer versions of these - the *long* vowels, which are `ɑː, æ, əː, iː, uː, ɔː`; or, they are combinations of these basic sounds, known as *diphthongs* - `aɪ, eɪ, ɔɪ, aʊ, oʊ, eə, ɪə, ʊə`.
In English, there are 6 basic vowels: `ʌ`, `e`, `ə`, `ɪ`, `ʊ`, and `ɒ`. Think of these 6 short vowels like the *roots* of a tree. The remaining more than a dozen vowels are either slightly modified, longer versions of these - the *long* vowels, which are `ɑː, æ, əː, iː, uː, ɔː`; or, they are combinations of these basic sounds, known as *diphthongs* - `aɪ, eɪ, ɔɪ, aʊ, oʊ, eə, ɪə, ʊə`.
元音的关键在于它们的**长短**。搞错元音的长短,一方面可能会造成错误或者理解困难。更为重要的是另外一方面 —— 会造成**节奏**混乱
> 在美式英语中,`eə, ɪə, ʊə` 这 3 个双元音被标注成 `er, ɪr, ʊr`,分别读作 `eər, ɪər, ʊər`
>
> In American English, the diphthongs `eə, ɪə, ʊə` are noted as `er, ɪr, ʊr`, which are pronounced respectively as `eər, ɪər, ʊər`.
The crux of vowels lies in their *duration*. If you mess up the length of vowels, not only could it lead to errors or difficulties in understanding, but more importantly, it could disrupt the *rhythm*.
元音的关键在于它们的**长短**。搞错元音的长短,一方面可能会造成错误或者理解困难。更为重要的是另外一方面 —— 会造成**节奏**[2.5.4](2.5.4-pace))混乱。
由于双元音由两个基础元音构成,所以**双元音**的长度与**长元音**相当。于是,英文**音节**的发声总体上倾向于比其它语言更长,因为 20 个元音中只有 6 个是短的,与之相对的,有 14 个是长的。这是一个相当显著的差异 —— 尤其在与亚洲语言相比的时候尤为明显,因为在大多数亚洲语言中元音(可能被称为韵母、母音)总是等长的,没有长短之分。

Since diphthongs are composed of two basic vowels, their length is equivalent to that of long vowels. As a result, English syllables tend to be pronounced longer overall than in other languages, given that only 6 out of 20 vowels are short, while the remaining 14 are long. This is a rather noticeable difference, especially when compared to Asian languages, where vowels always have equal length, with no distinction between long and short.
