音节
英语的音节是按照元音来确定的，简单来讲，有一个元音就有一个音节，辅音辅助元音形成音节。
根据英语单词中元音的个数，
分为单音节（1个元音）如：/fa:st/
双音节（2个元音）如：/ sist /
多音节（≥3个元音) 如：/ k l f l/

/ m dl/
/ pensl/
/ pi:pl/
/ te bl/
/ kl/
一归后；二分开
辅音连缀不分开
字母组合手牵手
双字相连不连手
前缀后缀独自走
音节划分的规律
Talk time
1、一归后：
当两个元音字母之间只有一个辅音字母时（r除外），通常将这个辅音字母划分在后面的音节里。
(元音+/辅音+元音)
2. 二分开：
当两个元音字母之间有两个辅音字母时，一般把它们分开，一边一个。
(元音+辅音/辅音+元音)
Talk time
a/go
af/ter
辅音连缀不分开：
辅音连缀必须划在一个音节里。如pr/tr/dr/fl/cl/sp/sw/scr等，不能分开，一般划归后面的音节。
字母组合手牵手：
（1）辅音字母组合划分音节时不能分开。
（2） 如果两个元音字母组合或者一个元音字母和一个半元音字母构成的组合发的是一个单元音或双元音，划分音节时，不能将其从中分开。
Talk time
a/gree
fa/ther
tow/er
双字相连不连手：
英语里的合成词，如how/ever ， birth/day work/shop等，原始的两个单词一般分开发音；若两个单词的头尾相连字母是字母组合或辅音连缀，仍然要拆开发音。
前缀后缀独自走：
前缀或后缀单独划分音节。
Talk time
rest/room
fall/ing
