双元音：1）合口双元音 2）集中双元音
双元音发音要领：①由两个元音组成，发音时由第一个向第二个元音的部位滑动，但不完全到达第二个元音的部位。发音过程中唇形、舌位及牙床开合程度均有相应的变化。②前重后轻，第一个元音响亮清晰。第二个元音轻弱模糊。③前长后短，第一个元音较长。第二个元音较短促。
1）合口双元音：[ei] [ai] [[ǝu] [au]
[ei]：
e.g. n a tion br ea k dec a de p ai nting w ai ter
make faces
no pain ，no gain. 一分耕耘一分收获
[ai]：
e.g.l i on h eigh t f igh t n igh t Fr i day
life on the island
Out of sight，out of mind。
注意辨音：[ai] [ei]

[ǝu]：
e.g. vide o sh ow sn ow j o ke sh ou lder
