【正确答案】正确答案：(1)The two phonetic forms of the affix; -ni; -li.(3 points) (2)The underlying form of the affix: -ing.(2 points) (3)/ing/→[ni]/[mu] [li]/[go](3 points)In the example,[ni]and[li]are two different phones and are variants of the phoneme /ing/. Such variants of a phoneme are called allophones of the same phoneme. In this case, the allophones are said to be in complementary distribution because they never occur in the same context. That is to say,[ni]always occurs after[mu], while[li]always occurs after[go].(4 points)
