【英語啟蒙】大家一起學發音：[?]和[ɑ:]該怎么發

The [?] sound. This is a vowel sound, a back vowel, which means it feels like it's coming from here in the throat, uh. It's very related to the [ɑ:] sound, the only difference being: ah, the jaw drops more. Uh is actually the sound that we use when we are thinking: uuuuhhhhhh... So as you can see, in American English it is an extremely neutral sound. To make this sound, the jaw drops just a bit and the tongue rests in the bottom of the mouth with the tip of the tongue touching the bottom teeth in the back. Uh, uh. Very neutral, very simple sound.

[?]是一個元音，是后元音，意思是這個音感覺像是從喉嚨這里發出來的。它與[ɑ:]音非常接近，唯一的區別是：發ah時，下巴下移得更多。Uh實際上是我們在思考時發出的那個音：uuuuhhhhhh... 所以你可以發現，在美式英語中，它是一個極其含糊的音。發這個音時，下巴只需略微下移，舌頭放在口腔下部，舌尖輕觸下排牙齒的后面。Uh, uh. 非常含糊簡單的一個音。
