摘要
In pronunciation teaching, learners may have difficulty when there is a ＂gap＂ in the phonemic system between L1 （the first or native language） and L2 （the second or foreign language）. In such a case, they tend to use their native language sounds in speaking the foreign language. Since some Chinese and English vowel sounds are easy to be confused, applying IPA cardinal vowels in the teaching of English pronunciation will help Chinese learners identify the difference between an English vowel sound and a Chinese vowel sound and thus enables them to make intelligible English speech sounds.
