to 在元音后 → da

这里先给大家列一下哪些是元音，哪些是辅音：

元音
单元音：[i:][i][ɔ:][ɔ][u:][u][ə:][ə][a:][ʌ][e][æ]
双元音：[ei][ai][ɔi][əu][au][iə][εə][uə]

辅音
10对清浊辅音：[p][b][t][d][k][g][f][v][θ][ð][s][z][ʃ][ʒ][tʃ][dʒ][ts][dz][tr][dr]
3个鼻音：[m][n][ŋ]
3个似拼音：[h][r][l]
2个半元音：[j][w]

*不要把元音、辅音的概念和元音字母、辅音字母搞混了。元音字母是a, e, i, o, u，其余21个字母都是辅音字母。

da 的发音多见于 go 之后；另外还是要注意，如果 to 需要被强调或者 to 后面没有其他单词，则 to 不发成 da。例如：
A: ﹡Kin﹡ya fix this? (Can you fix this?)
B: There's no way to.
