8第八頁，共17頁。拼讀規(guī)那么初探我們都知道，26個字母中，有5個元音字母，即a，e，i，o，u。有21個輔音字母，即b，c，d，f，g，h，j，k，l，m，n，p，q，r，s，t，v，w，x，y，z。“元〞是開始的意思，引申為根底，根本，所以元音字母是根本，是根底，是構(gòu)成音節(jié)的核心。一個元音字母可以自成一個音節(jié)，即自成一個單詞，如：a，I。但一個輔音字母不能。輔音字母，顧名思義是起輔助作用的字母。在元音字母的前面或后面各加上數(shù)目不等的輔音字母構(gòu)成一個音節(jié)。所以一個單詞中有幾個發(fā)音的元音字母，一般就有幾個音節(jié)。另外，5個元音字母，處在不同形式的音節(jié)中，發(fā)音是不一樣的。1、在元音字母前加輔音字母，即以元音字母結(jié)尾，這樣的音節(jié)叫絕對開音節(jié)。如：ha，be，hi，so，you。2、在元音字母后加輔音字母，即以輔音字母結(jié)尾，這樣的音節(jié)叫閉音節(jié)。如：an，end，is，old，us。3、在元音字母前后各加數(shù)目不等的輔音字母，是最尋常的一種音節(jié)。如：was，let，white，not，cut。其中如果最后三個字母符合“元音字母+輔音字母+不發(fā)音字母e〞，如：name，evening，nice，note，use等，這樣的音節(jié)叫相對開音節(jié)。9第九頁，共17頁。音節(jié)的分類
