音節(jié)是英語當(dāng)中最小的語音單位。每個音節(jié)含有一個音節(jié)核，通常由元音音素構(gòu)成，輔音是音節(jié)的分界線。所以，音節(jié)就分成單音節(jié)、雙音節(jié)和多音節(jié)。

?單音節(jié)詞

1.兩輔音之間不管有多少個元音，一般都是一個音節(jié)。如：bed、seat。2.兩元音字母之間有一個輔音字母時，輔音字母歸后一音節(jié)。如：stu?dent、la?bour。3.有兩個輔音字母時，一個輔音字母歸前一音節(jié)，一個歸后一音節(jié)。如：let?ter、win?ter。4.不能拆分的字母組合按字母組合劃分音節(jié)。如：fa?ther、tea?cher。

?雙音節(jié)詞

一般在第一個音節(jié)重讀。如：?sorry、?movie、?cover。
