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-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).

Diabetes
Most of the food we eat is turned into glucose(葡萄糖)for our bodies to use for ener-gy.The pancreas(胰腺), an organ near the stomach, makes a hormone called insulin to help glucose get into your body cells.When you have diabetes(糖尿病), your body either doesn't make enough insulin or can't use its own insulin well.This problem Causes glucose to build up in your blood.
You may recall having some of these signs before you found out you had diabetes.
* Being very thirsty.
* Urinating a lot -- often at night.
* Having unclear vision from time to time.
* Feeling very tired much of the time.
* Losing weight without trying.
* Having very dry skin.
* Having sores(疼痛)that are slow to heal.
* Getting more infections than usual.
* Vomiting(呕吐).
Two main types of diabetes are Type 1 and Type 2.Another type of diabetes appears during pregnancy in some women.It's called gestational(妊娠)diabetes.
One out of ten people with diabetes has Type 1 diabetes.These people usually find out they have diabetes when they are children or young adults.The pancreas of a person with Type 1 makes little or no insulin.People with Type 1 diabetes must inject insulin ev-ery day to live.
Most people with diabetes have Type 2 diabetes.The pancreas of people with such di- abetes keeps making insulin for some time, but the body can't use it well.Most people with Type 2 find out about their diabetes after age 30 or 40.
Some risk factors which make people more likely to get Type 2 diabetes are:
* A family history of diabetes.
* Lack of exercise.
* Weighing too much.
Diabetes can hurt your eyes, your kidneys, and your nerves.It can lead to problems with the blood circulation in your.body.Even your teeth and gums can be harmed.And di- abetes in pregnancy can cause special problems.
