【正确答案】正确答案：(1) The two phonetic forms are: [ ni ] and [ li ]. (2) The underlying form is [ ni ]. (3) [ni] → [ni] / [ - vowel] [ni] → [li] / [ + vowel, -u] In the word sungo, the last sound [o] is vowel so - ing form of the word is sungoli. While the last sound of the word dumu is [ u ] , which is quite an exception, the - ing form of the word is dumuni.
