Tap it back to me, OK?

把球发给我，好吗？

When we're pronouncing the TH sound really fast, sometimes we can just quickly tap the back of the teeth.

当我们非常快地发 TH 音时，有时我们可以快速地用舌头轻拍牙齿的后部。

So, if you tap the table with your finger, the table  taps your finger back with the same force.

因此，如果您用手指轻敲桌子，桌子也会以相同的力轻敲您的手指。

I'm actually very quickly tapping the back of my teeth; I'm not completely pushing my tongue between my teeth for that TH sound.

我的舌头快速地拍打我的牙齿后面；我并没有完全把舌头放在牙齿之间来发出 TH 音。
