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--not the old-styled body worn or over-the-ear aid, but an advanced personal sound system so small that it's like contacts (隐性眼镜) 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).

第三篇 Is the News Believable?Unless you have gone through the experience, yourself or watched a loved one's struggle, you really have no idea just how desperate cancer can make you. You pray, you rage, you bargain with God, but most of all you clutch at any hope, no matter how remote, of a second chance at lifE.For a few excited days last week, however, it seemed as if the whole world was a cancer patient and that all humankind had been granted a reprieve (痛苦减轻). Triggered by a front-page medical news story in the usually reserved New York Times, all anybody was talking about-- on the radio, on television, on the Internet, in phone calls to friends and relatives -- was the report that a combination of two new drugs could, as the Times. put it, 'cure cancer in two years.'In a matter of hours patients had jammed their doctors' phone lines begging for a chance to test the miracle cancer curE.Cancer scientists raced to the phones to make sure everyone knew about their research too, generating a new round of headlines.The time certainly seemed ripe for a breakthrough in cancer. Only last monthscientists at the National Cancer Institute announced that they were halting a clinical trial of a drug called tamoxifen (他莫昔芬) － and offering it to patients getting the placebo (安慰剂) --- because it had proved so effective at preventing breast cancer (although it also seemed to increase the risk of uterine (子宫的) cancer). Two weeks later came the New York Times' report that two new drugs can shrink tumors of every variety without any side effects whatsoever.It all seemed too good to be true, and of course it was. There are no miracle cancer drugs, at least not yet. At this stage all the drug manufacturer can offer is some very interesting molecules, and the only cancers they have cured so far have been in micE.By the middle of last week, even the TV talk-show hosts who talked most about the news had learned what every scientist already knew: that curing a disease in lab animals is not the same as doing it in humans. 'The history of cancer research has been a history of curing cancer in the mouse,' Dr. Richard Klausner, head of the National Cancer Institute, told the Los Angeles Times. 'We have cured mice of cancer for decades － and it simply didn't work in peoplE.'第 41 题 According to the passage, a person suffering from cancer willA.give up any hopE.B.pray for the health of his loved ones.C.go out of his way to help others.D.seize every chance of survival.
