第一篇
Crystal Ear
One day a friend asked my wife Jill if I wanted a hearing aid."He certainly does,"
replied Jill.After hearing about a remarkable new product, Jill finally got up the nerve to ask
me if I'd ever thought about getting a hearing aid. “No way,"I said. “It would make me
look 20 years older.""No,no,"she replied."This is entirely different.It's Crystal Ear!"
Jill was right. Crystal Ear is different一not the old-styled body worn or over-the-ear
aid, but an advanced personal sound system so small that it's like contacts(隐形眼镜)for
your ears.And Crystal Ear is super-sensitive and powerful,too.You will hear sounds your
ears have been missing for years.Crystal Ear will make speech louder,and the sound is
pure and natural.
I couldn't believe how tiny it is.It is smaller than the tip of my little finger and it's almost
invisible when worn. There are no wires,no behind-the-ear device. Put it in your ear and
its ready-to-wear mold(形状)fits comfortably. Since it's not too loud or too tight, you
may even forget that you,re wearing it!Use it at work or at play.And if your hearing
problem is worse in certain situations,use Crystal Ear only when you need it.
Hearing loss,which occurs typically prior to teenage years,progresses throughout
one's lifetime.Although hearing loss is now the world's number one health problem,nearly
90 percent of people suffering hearing loss choose to leave the problem untreated.For
many millions,treating hearing loss in a conventional way can involve numerous office
visits,expensive testing and adjustments to fit your ear.Thanks to Crystal Ear,the
"sound solution"is now convenient.Almost 90 percent of people with mild hearing loss,
and millions more with just a little hearing drop-off(下降),can be dramatically helped with
Crystal Ear.Moreover,its superior design is energy-efficient,so batteries can last
months.Crystal Ear is now available to help these people treat their hearing loss with a
small hearing amplifier(放大器).
According to the passage,hearing loss is
A.only a minor health problem.
B.the world's most common health problem.
C.merely a teenage disease.
D.an incurable disease.
