问题 Have you ever heard your own voice? "Of course," you say.
Has anyone else ever heard your voice? Again you say, "Of course."
But that’s not quite true. Nobody else has ever heard your voice—the way you hear it. When you talk, you set up sound waves(声波). The air outside your head carries the sound waves to your outer ears. But, of course, the sound of your voice begins inside your head. The bones (骨头) of your head pick up the sound waves, too. They carry the sound waves straight to your inner (里面的) ears. You get the sound from the outside and the inside too. Other people get just the sound waves from the outside. That’s why they don’t hear your voice the way you do.

选项 A、bones
B、air
C、waves

答案C

解析 根据原文,人说话时形成声波,因此选C。
