# 2.2.10. tʃ/dʒ
ʃ/ʒ 发声时舌尖贴近但没有接触到龈脊，tʃ/dʒ 则需要舌尖贴到龈脊，和 t/d 一样；但，无论是 ʃ/ʒ 还是 tʃ/dʒ 发声时舌背都抬得较高，舌尾抵到后牙。
When pronouncing ʃ/ʒ, the tip of your tongue should be close to, but not touching, the alveolar ridge. For tʃ/dʒ, however, you need to touch the alveolar ridge with your tongue tip, same as when pronouncing t/d. However, when pronouncing either the sounds ʃ/ʒ or tʃ/dʒ, the tongue roof should arch higher in the mouth, with the back of it touching back teeth.
为了让舌尖适应那个部位，不妨反复练习：
To get your tongue used to this position, it's a good idea to practice repeatedly:
