5. Comparison between /u:/ and / ʊ /
/u:/ is the highest back vowel, so the raised part of the tongue for /u:/ is higher than that for /ʊ/;
/u:/ 是高位后元音,因而舌位比/ʊ/高
The part of the tongue raised for /ʊ/ is not as back as that for /u:/;
/ʊ/的舌位没有/u:/的位置后
/u:/ has quite strong lip rounding while the lips are only slightly rounded for /ʊ/.
/u:/的口型非常圆而/ʊ/则稍圆即可

/ ɒ / 是低位元音而/ɔ:/ 是中位元音，所以/ ɒ / 的口型更大。
/ɔ:/ has quite strong lip rounding while the lips are only slightly rounded for / ɒ /.
/ɔ:/ 需要双唇呈滚圆形而/ ɒ /之需要双唇微圆即可。

17. / :/ ʌ

18. ar car star part dark march al calm palm half
/ :/

19. Comparison between / :/ and /Λ/
For / :/ the tongue is almost flat in the mouth. The tip of the tongue does not touch the lower teeth. The lips are neutrally open. As 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 / :/. Remember, / :/ is a back truly open vowel while /Λ/ is a central vowel.
/ :/ 在发音时，舌几乎平放于口中，舌尖并不触及下牙，而嘴唇自然张开。/Λ/在发音时，舌的中部抬升，舌尖触及下牙的根部，而口型张开但不及/ :/ 。所以，/ :/ 是大口后元音而/Λ/ 是中口元音。

Passage Practice
Folklore – Stories of Cultures Past
Folklore is the study of culture and history that is passed on through oral literature. The word “oral” means relating to the mouth, especially the spoken word. Oral literature includes stories, poems, and songs that are passed on by word of mouth. They are passed between family members and residents of villages, and from one generation to the next. Before written language and books, and long before computers, people passed information orally – by telling stories and singing songs. In some parts of the world, the oral tradition is still the primary way of communication.
There are many different purposes of these songs and stories. Some stories and songs taught religious beliefs; others celebrated romance and the triumph of good over evil. Still others gave important moral lessons, especially to children. Many of these stories contained supernatural elements like fairies, witches and magic spells.
