大家一起學發(fā)音：[?]該怎么發(fā)

Video Text:

The [æ] sound is a front vowel, which for me means it feels like it comes more from here, aa, than from here, ah. It's a bit difficult to explain, so I am going to explain it in terms of another vowel, and that is the [e] as in "pet" vowel. Both of them, eh, aa, you can see my tongue is up, as opposed to ah, "father", where you can see the dark space in my mouth. Aa, all you see is tongue. So it's coming up, and making a bit of a wall, so that you see this part. The way it's different from the eh vowel, which is more like this, eh, aa, is that the tip of the tongue is not touching underneath the teeth as it is in eh. This part of the tongue is a little more vertical and more spread for me, which feels like it creates more space back here. Aa, aa. Also the jaw has dropped a little bit more than on eh. Aa, aa. And the last subtle change that happens is here. It's easy to see. The lip comes up just a little bit. Pets, pats.

[æ]是一個前元音，它和[e]音的共同特點是發(fā)音時舌頭要抬起，這和發(fā)father中的[a:]音不同。發(fā)[a:]音時可以看見口腔中的黑影部分，但是發(fā)[æ]時只能看見舌頭。因為舌頭抬起形成了一座“墻”。

[æ]與[e]不同之處在于：發(fā)[e]時舌尖觸及下面的牙齒，但是發(fā)[æ]時并不觸及；發(fā)[æ]時舌根部分更加垂直、更加舒展，感覺在后部制造出了更多空間；另外發(fā)[æ]時下巴下移的位置要比發(fā)[e]時更多一點，而上嘴唇則要比發(fā)[e]時上移得更多。
