First, they are closely related to a vowel sound: /j/ is similar to the vowel /i:/ and /w/ is very much like the vowel /u:/. Because of this, they are also called semivowels. Secondly, neither /j/ or /w/ will ever occur in wordfinal position in English. Thirdly, they are both voiced consonants. In pronunciation, for /j/ the lips are relaxed and the tongue is in the high front space。 for /w/ the lips are rounded and the tongue is in the high back space. Then there is a movement away from these positions to whatever sound which follows. The more modern term for /j/ and /w/ is approximant, which is an articulation in which the articulators approach each other but do not get sufficiently close to each other to produce a plete consonant such as a plosive, nasal or fricative. /j/ and /w/ are not problem sounds for most Chinese EFL learners except it is necessary to emphasize the fact that the pronunciation of /w/ requires considerable lip rounding. /r/ /r/ is the other approximant besides /j/ and /w/ in English. The important thing about the articulation of /r/ is that the tip of the tongue approaches the alveolar area in approximately the way it would for a /t/ or /d/, but never actually makes contact with any part of the roof of the mouth. During the pronunciation, the tongue is in fact usually slightly curled backwards with the tip raised. /r/ is a difficult sound for many Chinese EFL learners. The difficulties
