# 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,舍尾抵到后牙。
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:
> * `ʃ... tʃ... ʃ... tʃ... ʃ... tʃ... ʃ... tʃ... ʃ... tʃ...`
> * `ʒ... dʒ... ʒ... dʒ... ʒ... dʒ... ʒ... dʒ... ʒ... dʒ...`
> * `ʃ... ʒ... ʃ... ʒ... ʃ... ʒ... ʃ... ʒ... ʃ... ʒ...`
> * `tʃ... dʒ... tʃ... dʒ... tʃ... dʒ... tʃ... dʒ... tʃ... dʒ...`
