Advice to the students
Many students confuse / ɑ: / and /Λ/ , so that their much /mΛt∫/ sounds much like march /mɑ:t∫/. To avoid this mistake, they should pay attention to the differences in the formation of the two vowels.
![Page 23: Chapter Three 第三章 中元音 Central Vowels: / Λ / / ә / / ә: / Time : 2 periods](https://reader033.vdocuments.site/reader033/viewer/2022061614/56649eaa5503460f94baefe6/html5/thumbnails/23.jpg)
Advice to the students
For /ɑ:/ the tongue almost lies flat in the mouth. The tip of the tongue does not touch the lower teeth. The lips are neutrally open.
For /Λ/, the part of the tongue that is raised is the centre of the tongue. The tip of the tongue touches the base of the lower teeth. The lips are widely open but not as wide as that for /ɑ:/.
