So, sometimes, we'll make it a true T. T, t. And then the schwa.

有时，我们把它发成一个正 T 音，t，t，加上一个弱央元音。

So first of all, the difference between T and D. T, T, T, T. Okay?

所以首先，T 和 D 之间的区别。 T，T，T，T。好吗？

D, D, D. Okay. T, T, T -- it's kind of without the force of my breath.

D，D，D。好的。 T，T，T - 有点没有我呼吸的力量。

Okay, so maybe you notice the T's, the double T's in sitting, those are flap T's. House sitting, pet sitting.

好吧，也许你注意到了 T，双 T 是坐着的，那些是 flap T。房屋看护，宠物看护。

T, t, t, but you will often hear that native speakers do make that a flap, it's just a little smoother.

T, t, t, 但你经常会听到说母语的人确实会拍打，只是更流畅一些。

That is not the OO vowel. Look it up in the dictionary, you'll see the schwa. T, T, T Today. Today. Today.

那不是OO元音。查字典，你会看到 schwa。今天，T，T。今天。今天。

So, instead of making the " t" sound: " T, t, t, t, t" , with your tongue in your mouth, you're going: " Uh, uh, uh" , down here in your throat.

所以，不是用舌头发出“t”音：“T, t, t, t, t”，而是在喉咙里发出“Uh, uh, uh”。
