英语发音规则
字母是书写英语单词的最小单位,音素是语言中最小的发音单位。字母分为元音字母和辅音字母两种。英语单词中的字母和单词读音中的各个音素并不都存在着对应关系。有时一个字母对应一个音素,有时两个或三个字母对应一个音素。
字组指的是一个或几个字母在一起,发一个音素。字组是拼读英语单词的基本单位,一个字组对应着一个音素。字组能很好地体现出单词的拼写和读音之间的对应关系,一个字组总是对应着一个因素。字组分为元字组和辅字组两类,元字组是对元音字母和元音字母组合的合称;辅音组是对辅音字母和辅音字母组合的合称。
元音字母重读开音节和闭音节中的读音

元字组在复合词非重读音节中的读音
复合词中的第二部分不标注重音符号, 但其中的元音字母或元音字组仍按重读音节拼读规则拼读。例如:everyday/eɪ/, handbag/æ/, blackboard/ɔ:/。有些词随着语言的发展, 前后两部分已失去其单独存在的意义, 融合成为一个词。其中的非重读部分要按非重读音节的读音规则发音。例如:holy(神圣)+day/eɪ/(日子)=holiday/ɪ/(假日):break(中断)+fast/α:/(斋戒)=breakfast/ə/(早餐);cup(茶杯)+board/ɔ:/(木板)=cupboard/ə/(碗柜)。
辅字组的读音
