-> * For `t/d`, the tongue tip begins at the front part of *alveolar ridge* ③;
-> * `s/z` 要相对于 `t/d` 往前一些，贴近但没有接触到牙齿和牙龈的接缝处 ②；
-> * For `s/z`, it's closer to the front compared to `t/d`, near but not touching the *seam* between the teeth and gums ②;
-> * `θ/ð` 要相对于 `s/z`再往前一些，贴在牙齿上，或者伸出牙齿一点点 ①；
-> * For `θ/ð`, it's even more forward than `s/z`, resting on the *teeth*, or protruding a bit ①;

-中国学生会不由自主地用 `dʒ` 替代 `ʒ` —— 因为 `dʒ` 是一个他们熟悉的辅音，相当于中文拼音中的 `zh`。`ʒ` 和 `dʒ` 的区别在于，`ʒ` 发声时舌尖贴近但没有接触到龈脊；而 `dʒ` 发声时起始的舌尖贴在龈脊（与 `ʒ` 同一个位置 ③）。

-Chinese students tend to instinctively substitute `ʒ` with `dʒ` - a consonant they're familiar with, equivalent to the `zh` in Chinese Pinyin. The difference between `ʒ` and `dʒ` is that, when pronouncing `ʒ`, the tip of the tongue is close to but not touching the the *alveolar ridge* while for `dʒ`, the tongue tip starts at the the *alveolar ridge* (same position as `ʒ` ③).

-少数人知道  `dʒ` 替代 `ʒ` 不是一回事，但，由于舌尖起始位置并不准确，所以他们说出来的 `ʒ` 听起来更接近 `r` —— 舌尖缩得过头了 —— `r` ④ 发声时起始的舌尖位置相对于 `ʒ` ③ 要更靠后一点。

-A few understand that substituting `dʒ` for `ʒ` isn't accurate. However, because their tongue tip positioning isn't precise, their `ʒ` sound often ends up sounding more like `r` - they retract their tongue tip too far - `r` ④ is pronounced with the tongue tip further back compared to `ʒ` ③ .
