音节是英语当中最小的语音单位。每个音节含有一个音节核，通常由元音音素构成，辅音是音节的分界线。所以，音节就分成单音节、双音节和多音节。 ▶单音节词 1. 两辅音之间不管有多少个元音，一般都是一个音节。如：bed、seat。 2. 两元音字母之间有一个辅音字母时，辅音字母归后一音节。如：stuˈdent、laˈbur。 3. 有两个辅音字母时，一个辅音字母归前一音节，一个归后一音节。如：letˈter、winˈter。 4. 不能拆分的字母组合按字母组合划分音节。如：faˈther、teaˈcher。 ▶双音节词 一般在第一个音节重读。如：ˈsrry、ˈmvie、ˈcver。
1. 有 a-、be-、de-、re-、res-、in-、im-、en-、em-、es-、ex-、cn-、cm-、dis-、mis-、pre-、per-、pr-、trans- 等前缀的词，第二个音节是重音。如：beˈlieve、deˈcide。 2. 有de-、in-、re-、cn-、pre- 等前缀的单词的重音与词义和词类有关， 一般名词的重音在第一个音节上，其他的词性在第二个音节上。如:ˈpresent、preˈsent。 3. 有些复合词和带有前缀 re-、ex-、un-、pre-、pst-等的词，有两个重音。如：ˌutˈside、ˌreˈtell。 ▶多音节词 一般倒数第三个音节是重音。如：ˈdifficult、pprˈtunity、eˈcnmy、uniˈversity。
