 而 `t, d, s, z` 这四个辅音发声时起始的**舌尖位置**，同样影响基于它们的另外三个辅音，`ʃ, tʃ, dʒ`…… 比较有趣的是，中文的普通话里恰好有对应的**卷舌音**，`sh, ch, zh`。找对发这三个声母发声时起始的舌尖位置，从那里开始读英文的 `t, d, s, z` 就对了。只不过，有一点点的区别，中文的 `sh, zh` 舌尖顶着上颚，同样的方式读出来的是英文的 `ʃ, dʒ`。而英文的 `s, z` 离上颚还有一点距离，但，不像中文的 `s, z` 那样靠近牙齿。
 
-另外，美国人在说 `t` 这个辅音的时候，经常会把它读成**送气音**（*asperated*），即，发着 `h` 的音读出，比如 *time* `/tʰaɪm/`。

 对中文普通话使用者来说，必须为这几个辅音学习新的发声方式。可以用 *students* `/ˈstudənts/` <span class="speak-word-inline" data-audio-uk="/audios/students-uk.mp3" data-audio-us="/audios/students-us.mp3"></span> 这个词作为起步反复练习。以后随时注意这些辅音发声时起始的 “舌尖位置”。
