一个英语单词音标中既有i和I是怎么回事？

Answer 1

晕啊,太多了，发发慈悲,给你打几个吧: [i:] 以e结尾的重读开音节: she, be, he, me, we, the, zebra, e-mail 以“e + 辅音+ e”结尾的重读开音节： these, evening, Chinese, Japanese 字母组合ea: clean, please, speak, read, teacher 字母组合ee: tree, meet, feet, see, green, three, thirteen, fourteen, fifteen, eighteen 其它字母或组合: policeman, key, people [i] 字母i在重读闭音节中: it, is, his, big, him, fridge, give, sing, with, live, six, which, ill, think, miss, hill, in, this, sit, different, window, cinema, animal, chicken, sister, picture, children, 重读e: English, England,

我问的是区别，比如guilty

Answer 2

现行教科书中，一般字母y出现在词尾，且该音节为非重读音节，那就是标注为/i/, 其他时候的短音/i/都是标注为/I/。

Answer 3

一个单词音标有的有几个音节，有重读的音节和非重读音节，自然也就有长元音i和短元音I

长元音不是i：吗
