[u:]. This is another back vowel. It's the most closed. Oo. To make this, my tongue comes up just a little bit in the back, it kind of fattens up. Oo. So, the tip of my tongue is not at the front of my teeth. And the lips, of course, come in. Oo. Side shot: oo. Ah, uh, oh, oo.
[u:]又是一個后元音，它是開口最小的一個音。Oo. 發(fā)這個音時，舌頭只是在舌根處略微抬起，有些攤平。Oo. 所以，舌尖并不碰到門牙。另外嘴唇當(dāng)然要向內(nèi)聚攏。Oo. 從側(cè)面對比一下：oo. Ah, uh, oh, oo.
