Since the tongue's movements are invisible during speech, it's difficult for learners to guess the second method, which involves lifting the back part of the tongue, and allowing the sides of the tongue to touch the back teeth. The center of the tongue's rear is slightly lowered, creating a groove for the air to pass through and generate the sound.
+事实上，其他的儿化音也都可以用这种方式发声。不妨用这种方式重新试试 *card* kɑːrk, *mark* mɑːrk；再试试 *door* dɔːr, *short* ʃɔːrt, *poor* pʊr, *your* jʊr…… 试过之后，再进行比较，你会发现更多的时候，第二种方式比第一种方式更方便。

+In fact, you can use this method to pronounce other rhotacized vowels as well. Give it a shot with words like *card* kɑːrk and *mark* mɑːrk again; and then try it out with *door* dɔːr, *short* ʃɔːrt, *poor* pʊr, and *your* jʊr... After giving it a try, you'll notice that more often than not, the second method is more convenient than the first.

另外，辅音 ʃ/ʒ、tʃ/dʒ 在发音的时候，舌尾也是同样的位置。
Moreover, when pronouncing the consonants ʃ/ʒ ([2.2.8](2.2.8-ʃʒ)) and tʃ/dʒ ([2.2.10](2.2.10-tʃdʒ)), the position of the back part of the tongue is the same.
