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 me nerve to ask me if I'd ever thought about getting a heating 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 tight. Crystal Ear is different—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 fight, 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 life time. 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, 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 heating amplifier(放大器).

D. It is wireless.

【正确答案】 C

【答案解析】[解析] 细节题。本题利用题干不好定位，可以改为定位选项。利用选项关键词可以定位到文章第二段第二句“It is smaller than the tip of my little finger and it's almost invisible when worn.”，意为“水晶耳比小手指的尖端还小，并且当戴着它时几乎看不见它。”由此可知，水晶耳几乎看不见，并不等于看不见，所以答案为C。

A. you can control its volume
B. you needn't take it off everyday
C. it is solar-powered
D. it saves power

【正确答案】 D

【答案解析】[解析] 细节题。本题利用题干关键词无法定位到相关句子，可以利用选项进行定位。文章第三段“Moreover, its superior design is energy efficient, so batteries can last months.”，意为“然而，它卓越的设计是高效节能的，所以电池可以持续使用数月。”由此可知，水晶耳的非凡设计使其十分节能，所以正确答案为D。

单选题 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

【正确答案】 B

【答案解析】[解析] 细节题。利用题干关键词hearing loss可以定位到第三段，其中“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.”，意为“虽然听力损失是现在世界头号健康问题，近90%的患有失聪的人选择不对其进行治疗。”所以正确答案为B。

单选题 Many people leave their hearing problem untreated, because ______.

A. it is not serious
B. Crystal Ear is not yet available
C. it is not easy to have it treated
D. they don't want to look old

【正确答案】 C

【答案解析】[解析] 细节题。利用题干关键词hearing loss和untreated可以定位到文章最后一段“...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”可知，许多失聪患者有病不治的原因可能需要去很多次医院，检测的成本昂贵以及需要多次调整来适合病人的耳朵，所以选项C最合适。
