一、如何区分th在英语单词中的发音
1. th位于词首时,可以从词性上判别其应有的读音。在名词、动词、形容词和数词中th发清辅音。如:thing, theatre, thunder, thermos, Thursday, theory, theme, throat, think, thank, , thicken, thirteen, thirty, third, thousand, thick, thirsty,
2. 在代词和一些功能词中th发浊辅音.如: them, their, theirs, there, the, than, then, though, therefore, they。只有介词through是个例外。
3. 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。
4. 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。例如:feather, weather, whether, leather, further, father, bathe, breathe, southern, northern, either等。在其他情况下发清辅音。例如: faithful, method, nothing, anything, healthy, wealthy。
试读下列单词: mother, father, another, brother, health, wealth
二、如何区分单词后加“ed”后,这个ed怎么读?
规则动词加ed后的发音: 清念 /t/ ,元浊/d/ ; /t/ /d/ 之后念/id/ 1、以清辅音结尾(不包括在词尾发音的 t 和 d), 加了-ed后,发/t/ .例:finished helped passed cooked
2、.以元音或浊辅音结尾的,加了-ed后, 发/d/. 例:borrowed enjoyed called moved 3、结尾是发音的 t 或 d,加了-ed后,发/id/. 例:wanted shouted needed counted
三、如何区分单词后加“s” 或“es”后,这个单词的读音。
1、大多数动词在词尾加“S”在清辅音后发音为[s],在浊辅音及元音后发音为 [z]。如: ①stop-stops [s] ; make-makes [s] ②read-reads [z] ; play-plays [z] 2、 以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”读[iz] 如: fly-flies [z]; carry-carries [z] study-studies [z]; worry-worries 3、 以“s, x, ch, sh”结尾的,在词尾加“es”,发音为[iz] 如: teach-teaches [iz]; watch-watches [iz]
4、 以“o”结尾的动词,加“es”,读[z] 如: go-goes [z] do-does [z]
5. 以不发音字母“e”结尾的开音节词,如果尾音是[s],[z]时,加“s”后字母“e”
发音, 与所加“s” 一起读做[iz]。 如: close-closes [iz] 6. 特殊词。如: do [du:]-does [dz] say [sei]-says [sez]
