小柳给大家谈谈th的两种发音规则总结，以及th的两种发音应用的知识点，希望对你所遇到的问题有所帮助。

1、(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,tder,thermos,Thursday,theory,theme,throat,thread,think,thank,thrive,thicken,thir,thirty,third,thousand,thick,thirsty,thoughtful,thorough在代词和一些功能词中th发浊辅音.如：them,their,theirs,there,the,than,then,though,thus,therefore,they.只有介词through是个例外.(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,ooth中读浊音.(3)th在词中并且后面接er时,或者后一个字母是不发音的e时,通常也发浊辅音.例如：feather,weather,wher,leather,further,father,bathe,breathe,southern,northern,either等.在其他情况下发清辅音.例如：author,faithful,mod,nothing,anything,healthy,wealthy.试读下列单词:mother,father,another,brother,health,wealth请采纳。
