5.( ) The story tells us that
_________.
A. a dream may come true some time later

D. people should always believe their dreams
( B )
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.
