新东方4+1语音语调flash课程帮您把握 “ 语音 ” 和 “ 语调、节奏 ”双过关的宗旨，兼顾连续、缩读和弱读的音变， 短期突破语音。

基本分类及常识

语音分元音和辅音两大类，每一个语音必定属于这两者之一。
All the phonetic sounds are divided into vowel and consonant.

元 音
元音是一种有声音，发音时用舌头和嘴唇使口腔定形，声带震动。同时气流从咽腔和口腔不断流出，不受阻碍，也没有变狭窄，因而听不出摩擦。
Vowel：vowel is a voiced sound. The vocal cords vibrate, while the oral cavity is sampled by the tongue and lips. At the same time, the air is passing from the larynx to the mouth without obstruction.

辅 音
（在正常言语中）除元音外所有的其他音都叫辅音。一部分辅音发音时，气流不通过口腔，如[m]；另一部分辅音发音时，气流在通过口腔时，受到这样或那样的阻碍，或在口腔中的某个点受到摩擦。
Consonant：All the other sounds except vowels are consonants. For some consonants, when they are pronounced, the air doesn’t pass the mouth as /m/. for others , when it is passing through the oral cavity, the air will receive this or that kind of obstruction. Or it is affricated at a certain point.

元音和辅音的特征
The characteristics of the Vowels and Consonants：Vowels are sounds produced without obstruction of the air stream in the mouth. In producing them there is vibration of the vocal cords. So all vowels are voiced. Consonants are sounds produced by some form of obstruction of the air passage and maybe either voiced or voiceless.

元音分类 A
根据发音时舌头在口腔中抬起的部位不同，我们把单素元音分为前元音、中元音和后元音。
（When we pronounce a monophing ,the jaw, tongue and lips do not move at all.There are twelve monophthongs,and we divide them into front vowel,central vowels and back vowels,both in British English and American English based on the parts of the tongue that count them.

Part One 前元音听辨及跟读
