thin
[θɪn]
中的th发
[θ]
与它发音一样的十个单词:
tooth
mouth
health
thief
three
thick
north
throw
thank
birthday
分析:
1、th的发音只有两个:清辅音/θ/
和
浊辅音/ð/。
2、th的发音规则:
(1)、th位于词首时,可以从词性上判别其应有的读音。
a、在名词、动词、形容词和数词中th发清辅音,发/θ/.
如:thing,
theatre,
thunder,
thermos,
Thursday,
theory,
theme,
throat,
thread,
think,
thank,
thrive,
thicken,
thirteen,
thirty,
third,
thousand,
thick,
thirsty,
thoughtful。
b、一般情况下,在代词、冠词、介词、连词或副词中的字母组合th,读浊辅音/ð/。
例:within/wi'ðin/,without/wi'ðaut/,these/ði:z/,therefore/'ðeәfɔ:/,
al-though/ɔ:lðәu/,those/
ðәuz/,the/
ðә/,thus/
ðas/,them/ðem/
发音特殊的单词:through/θru:/,throughout/θru:'aut/
c、只有介词through是个例外,发/θ/。
(2)、th位于词尾(或音节之尾)时,其读音多数是清辅音,如:bath,
breath,
tooth,
等。
只有在少数单词中,如:with,
smooth
中读浊音,发/ð/。
(3).th在词中并且后面接er时,或者最后一个字母是不发音的e时,通常也发浊辅音,发/ð/。
如:feather,
weather,
whether,
leather,
further,
father,
bathe,
breathe,
southern,
northern,
either等。
(4)在复合词中,th的读音与在原词中的读音相同。
例:something
/
'samθiŋ/,anything/'eniθiŋ/,nothing/'naθiŋ/
within/wi'ðin/,without/wi'ðaut/等。
(5).其他无规则可循的词分列如下:
maths/mæθs/,arithmetic/ә'riθmәtik/,clothing/klәuðiŋ/,
clothes/klәuðz/,southern/'saðәn/,northern/'nɔ:ðәn/,
worthy/'wә:ði/,author/'ɔ:θә/,sympathy/'simpәθi/
