Details of the teaching plan: Front Vowels & Central Vowels In this unit, we will learn the front vowels and central vowels in English. Vowels are sounds in which there is no obstruction to the flow of air as it passes from the larynx to the lips. There are 20 vowels in English, among which 12 are pure vowels and 8 are diphthongs. The English pure vowels can be classified according to 1) the height of the raised part of the tongue; 2) the part of the tongue raised, and 3) the position of the lips, i.e. whether they are rounded or unrounded. There are four front vowels in English: /i:/, /i/, /e/ and /æ/. The reason these are called front vowels is that the tongue body is shifted forward, causing the vowels to be produced in the front of the mouth. In addition, the front vowels may be subdivided into those that are high (or close), like /i:/ and /i/, mid, like /e/, and low (or open), like /æ/. For the two vowels in the high front space, /i:/ and /i/, the tongue is close to the hard palate. Likewise, for the low vowel /æ/ the tongue is nearly flat and
