问题描述
为什么把 /w/,/j/ 叫做半元音?请老师举例详说。谢谢!
老师答疑
陈老师:
半元音(semivowel)是指介于元音跟辅音之间的音,其特点为语音学上指擦音中气流较弱,摩擦较小.
48个国际音标详细讲解
第一总结:语音知识
【一】,什么是音素:音素是语音的最小单位.
【二】,音素的分类:元音和辅音.
【三】,音素的个数:共计48个;其中元音20个;辅音28个
【四】,什么是音标:记录音素的符号叫音标.
【五】,什么是国际音标:国际音标是由国际语音协会规定的一套音标,用来记录全世界各主要语言的语音.
【六】,开音节:(1)辅音+元音+辅音+e 例如:name;bike;home;plane
(2)辅音+元音 例如: he;go;do;be;tree;three;hello
【七】,闭音节(1)辅音+元音+辅音
例如:sit ; bed ; bad; hot;cup;let;map
(2)元音+辅音 例如:it;is;in;up;of;
【八】,重读音节:单词中发音特别响亮的音节.
【九】,元音的定义:发音时声带振动,呼出气流通过口腔没有形成阻碍,这样形成语音称之为元音.
【十】,无论声带是否振动,发音时呼出气流通过通过口腔或鼻腔受到一定阻碍,这样形成语音叫做辅音;发音时声带振动称为浊辅音;发音时声带不振动称为清辅音
【十一】元音发音部分:
(1)单元音:[ i:] [ i ] [ ɔ:] [ ɔ]
前元音:[i:] [i] [ e ] [ æ] [ u: ] [ u ] [ ə:] [ ə ]
中元音:[ʌ] [ə:] [ ə ] [ ɑ:] [ ʌ ] [ e ] [ æ]
后元音:[ ɑ:] [ u:] [ u ] [ɔ:] [ɔ]
(2)双元音:[ei]、[ai]、[ɔi]、[ɛə]、[uə]、[iə]、[au]、[əu]
【十二】辅音发音部分辅音音标28个
辅音(又叫子音):不论声带振动与否,发声时呼出的气流通过口腔或鼻腔时受到一定阻碍,
这样的语音称为辅音。辅音发音不响亮,口腔中气流受到阻碍,不是构成音节的主要音。
英语中有28个辅音。共48个音素。
清辅音:[p] [t] [k] [f] [s] [θ] [∫] [ t∫] [tr] [ts]
浊辅音:[b] [d] [g] [v] [z] [ð] [з] [dз] [dr] [dz]
鼻音: [m] [n] [ŋ]
摩擦音: [h] [r]
舌头侧音:[l]
半元音 [j] [w]
【十三】发音方法
(1)清辅音:(发音时候声带不震动;有气无声)
[p] [t] [k] [f] [ ∫ ] [s] [θ] [ts] [tr] [t∫]
(2)浊辅音:(发音时候声带震动;有声无气)
[b] [d] [g] [v] [ з] [z] [ð] [dz] [dr] [dз]
(3) 爆破音:
[p] [t] [k] (清辅音)(气流从口腔冲出,送气有力 )
[b] [d] [g] (浊辅音)(气流从口腔冲出,送气有力 )
(4)摩擦音:
[f] [s] [ ∫ ] [θ] [ h] (清辅音)
[v] [z] [з] [ð] [ r ] (浊辅音)
(摩擦音:气流发发音器官的缝隙,发生磨擦而发出的音 )
(5)破擦音:
[ t∫ ] [tr] [ts] (清辅音)
[dз ] [dr] [dz] (浊辅音)
(破擦音为:爆破音和磨擦音的结合发出的音)
(6)鼻辅音:
[m] [n] [ŋ](气流从鼻腔通过 )
(7)舌侧音:
[l] (气流从舌的两旁空隙处流过 :也叫旁流音)
(8)半元音:
[w] [j] ((这两个也属磨擦音) 像元音一样,气流直接从口腔通过,但又像辅音一样,气流通过时与发音器官稍有磨擦 )
