 很多地区的人基于自身母语的习惯，会把 <span class="pho">tr</span> 和 <span class="pho">dr</span> 分开着连续读出的。比如，*tree*，印度人可能会把它读成 <span class="pho alt">tɤ.riː</span><span class="speak-word-inline" data-audio-other="/audios/us/tree-ru-ru.mp3"></span>，其中的 <span class="pho">t</span> 干脆读成 <span class="pho">d</span>，并且 <span class="pho">r</span> 还会用齿龈颤音；再比如，*driver*，可能会被俄罗斯人读成 <span class="pho alt">dɤ.raɪvə</span><span class="speak-word-inline" data-audio-other="/audios/us/driver-ru-ru.mp3"></span>，其中的 <span class="pho">r</span> 同样会用齿龈颤音。
 
-People from many regions, guided by the habits of their native languages, may pronounce <span class="pho">tr</span> and <span class="pho">dr</span> as separate, continuous sounds. For instance, someone from India might pronounce *tree* as <span class="pho alt">tɤ.riː</span><span class="speak-word-inline" data-audio-other="/audios/us/tree-ru-ru.mp3"></span>, with the <span class="pho">t</span> articulated as <span class="pho">d</span>, and the <span class="pho">r</span> as a [*voiced alveolar trill*](https://en.wikipedia.org/wiki/Voiced_dental,_alveolar_and_postalveolar_trills). Similarly, the word *driver* might be pronounced as <span class="pho alt">dɤ.raɪvə</span><span class="speak-word-inline" data-audio-other="/audios/us/driver-ru-ru.mp3"></span> by a Russian speaker, again using a voiced alveolar trill for the <span class="pho">r</span>.

 不管人们用什么样的语言，笑声总是一致的…… 因为地球人在发笑的时候都使用大致一样的声音，都包含 <span class="pho">h</span> 这个音 —— 于是，没有人会觉得 <span class="pho">h</span> 的发音有什么困难。
 
-No matter what language people speak, laughter sounds the same... That's because people all over the world use roughly the same sound when they laugh, one that includes the <span class="pho">h</span> sound. As a result, no one finds it difficult to pronounce <span class="pho">h</span>.

+
+不过有一个细节需要注意。在日常对话中，不能么正式或者速度较快的时候，<span class="pho">h</span> 会被 “击穿”。比如，*Did he do that?* 这句话，更可能被说成 <span class="pho alt">dɪ diː duː ðæt</span> <span class="speak-word-inline" data-audio-us-male="/audios/us/sentence-he-do-alloy.mp3" data-audio-us-female="/audios/us/sentence-he-do-nova.mp3"></span>，而不是正式的那样 <span class="pho alt">dɪd hiː duː ðæt</span>。
+
+However, there's one detail to keep in mind. In everyday conversations, especially when speaking informally or quickly, the <span class="pho">h</span> sound can get “dropped.” For example, the sentence *Did he do that?* is more likely to be pronounced as <span class="pho alt">dɪ diː duː ðæt</span> <span class="speak-word-inline" data-audio-us-male="/audios/us/sentence-he-do-alloy.mp3" data-audio-us-female="/audios/us/sentence-he-do-nova.mp3"></span> rather than the formal one as <span class="pho alt">dɪd hiː duː ðæt</span>.
