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 h 这个音 —— 于是，没有人会觉得 h 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 h sound. As a result, no one finds it difficult to pronounce h.

+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 h sound. As a result, no one finds it difficult to pronounce h.
+
+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，h 会被 “击穿”。比如，*Did he do that?* 这句话，更可能被说成 dɪ diː duː ðæt ，而不是正式的那样 dɪd hiː duː ðæt。
+
+However, there's one detail to keep in mind. In everyday conversations, especially when speaking informally or quickly, the h sound can get “dropped.” For example, the sentence *Did he do that?* is more likely to be pronounced as dɪ diː duː ðæt rather than the formal one as dɪd hiː duː ðæt.

+For more examples:
+
+* I heard him singing.
+* Has he arrived yet?
+* He helped her with the project.
+* His house is over there.
+* He's holding the door.
