FOOD和FOOT本来就不是一个元音

元音如果后面跟着浊辅音持续时间就会长点

比如pig要比pick长， 而且FOOD和FOOT本来
就不是一个元音FOOD的元音可LUKE一样FOOT
的元音和LOOK一样

Vowels: Compare other u/oo sound

To create the oo sound, the lips are made into a small and tense circle at the same time as the body of the tongue is pushed back (allowing the back of the tongue to raise toward the soft palate). To transition into the other u sound, the tongue relaxes a little and the back of the tongue lowers slightly while the lips loosen into a more open and relaxed circle.


other u oo sound
