一个音节通常都有一个元音。但下列单词中粗体的辅音也是一个独立的音节。
A syllable usually has a vowel sound. However, the consonant
sounds in bold in the following words are separate syllables too.
little middle pencil people table uncle
音节:有的单词只包括一个音节,有的单词包含两个、三个或更多的音节,分别称为单音节词、双音节词和多音节词。 单音节词一般都是重读的。双音节词一般只有一个音节是重读的。多音节词除了重读音节外,有时还有一个次重读音节。
音节的核心是元音。少数辅音字母,如l、m、n也可以构成非重读音节。一个音节里可以只有一个元音字母而没有其他字母,如i 、a。元音字母的前面或后面可以有一个或两个辅音字母。如we, she, at, ask, box, them, desk, middle, letter等。
