You can have a retroflex R where your tongue essentially curls upside down under your palatal arch.

你可以发一个卷舌 R ，发这个音你舌头实际上是在你腭弓下弯曲。

So, in this video I'm focusing specifically on the retroflex sound.

所以，在这个视频中， 我特别关注卷舌音。

The way I like to make the " r" is what we call the " retroflex way" .

我喜欢制作“r” 方式就是我们所说“卷舌方式” 。

In this video, we're going to talk mainly about the retroflex " r" , because that's the one that I do.

在本视频中， 我们将主要讨论卷舌音“r”，因为我就是这样做。

So, for the retroflex, if you make a " d" sound, so say " da" , " da" , your tongue actually goes up, kind of like the " r" does.

所以，对于卷舌音， 如果你发出“d” 声音，那么说“da” ，“da” ，你舌头实际上会上升，有点像“r” 。
