大家一起学发音：[r]该怎么发

Video Text:

The [r] sound. I think this is one of the hardest sounds to teach to those who don't have it in their native language. So let's break it down. For me, the sound kind of comes from uh, uh, this kind of sound when you loosely let air pass through your vocal cords. Then when you form the mouth around that uh-uh-uh-ur-ur-rr-rr, it's kind of bringing the sound from the vocal cords more forward. Rr. So, the tongue. The tongue is fattening up a little bit in the back, and it's coming up, and it's pressing the insides of the top teeth. Rr, rr. As it comes up to do that, the rest of the tongue goes back down a little bit in the front, but it's not just laying there. It's very active, and it's actually pointing up and out a little bit. But it's not touching anything. Rr, rr, rr, rr. The teeth come close to being together, without being together. Rr, rr. And, as you can see, the lips come in a little bit at the edges, which means also that they push out a little bit. Rr, rr.在我看来，对于母语中没有[r]这个音的人来说，[r]是最难教的音标之一。下面我来分解一下它的发音动作。这个音呢是类似uh, uh的音，也就是声带放松让气流通过时所发出的音。然后，当你慢慢地改变口型发出uh-uh-uh-ur-ur-rr-rr，感觉有点像把声音的位置从声带往前面移动。Rr。接下来我们讲讲舌头。舌后部肌肉处于稍微绷紧的状态，向上抬起，并顶在上齿龈上。Rr, rr。当舌后部往上走时，舌前部稍往后收，但不是完全放松，它也要用点力，要往前上方微微伸出，但不用触碰到任何部位。Rr, rr, rr, rr。发音时，上下排的牙齿呈将要闭合的状态，不过最后不要咬合在一起。Rr, rr。另外，你可以看见，嘴唇稍稍翻出来一点，说明它在往外用力。Rr, rr。
