英文字母所含的音素是什么意思

英语是拼音文字,由字母组成单字.英语字母共有二十六个,其中字母a、e、i、o、u是元音字母,其余二十一个是辅音字母,其中y字母有时当元音字母用.
英语中,大多数单字的发音是有规则可循的,单字的发音是由字母和字母组合来表示的,所以英语就叫做拼音文字,即用符号（字母）来表示语音的文字.学英语首先要学好五十个KK音标,再按照发音规则拼读单字,叫做自然发音法.
五个元音字母在重读开音节（最后一个字母是元音字母）或重读相对开音节（元音字母后面紧接一个辅音字母和一个不发音的元音字母e）中,都念长音,即这个字母的名称：
labor 劳动
name 名字
be 是
these 这些
I 我
die 死
nice 好的
fire 火
no 没有
whole 整个
mu 希腊字母μ
cue 线索
use 使用
五个元音字母在重读闭音节中念短音：
a /æ/ thank plant
e /ε/ get pen
i /ɪ/ wish silly
o /α/ stop box
u /ʌ/ up but
元音字母组合的发音也是有规律可循的.
al /ɔ/ call fall small tall wall
ai /e/ mail maid rain bait
ay /e/ bay stay hay tray
ar /αr/ dark hard barn farm are
air /εr/ air chair fair hair
are /εr/ care dare hare
au /ɔ/ caught taught
aw /ɔ/ law saw paw draw
ea /i/ pea read Jean heat meal
/ε/ bread dead death head weather read
ear /ɪr/ pioneer engineer
ei /i/ receive seize /e/ eight neighbor
er /ɝ/ her mermaid /ɚ/ winter mother painter
ir /ɝ/ fir shirt
oa /o/ coat road soap soak toast goal loaf

oo /u/ moon noon school soon too /ʊ/ book cook foot good /ʌ/ blood
oor /or/ door floor
or /ɔr/ fork Ford born storm

ou /aʊ/ house our mouth loud thousand found /ʌ/ enough touch trouble young /ʊ/ could
our /or/ course four fourth
ow /aʊ/ wow clown crown
oy /ɔɪ/ boy enjoy joy toy
ur /ɝ/ purse burn
辅音字母和辅音字母组合的发音基本上固定不变,如：
b /b/ able baby bad big black
c /s/ city certainly receive /k/ car catch class come cup
ck /k/ back black check kick
ch /tʃ/ charge check children /k/ Christmas chemical school
dg /dʒ/ bridge judge
dr /dr/ drink driver dry
g /g/ egg get give /dʒ/ German giant large
gh /f/ enough laugh
h /h/ have head hope hot how
k /k/ keep kind kite
n /n/ naked near night son /ŋ/ thank ink think English language
ng /ŋ/ thing song
ph /f/ phase phone photograph
s /s/ same sea sun /z/ has reason /ʃ/ sugar sure /ʒ/ television revision
sh /ʃ/ shame she sheep shine wish
t /t/ little sit tea /ʃ/ action nation
th /θ/ both think three /ð/ the they this those
tr /tr/ train travel trip
然而,在一些字中有一些辅音字母（组合）会省略不发音,如：
b comb climb tomb debt doubt
c indict scene pick lick
ch yacht
g gnash design gnarled paradigm
gh eight high night dough bought caught
h hour honest rhyme khaki oh ah Fahrenheit shepherd exhaust
k knight knife knock know
n column
p pneumonia psychology receipt
s island aisle Arkansas Illinois
t listen castle depot ballet
w write wrong two answer sword who whom whole
只要你记住了KK音标和发音规则,就可拼读单字.希望我能帮助你解疑释惑.
