Almost Human?
Scientists are racing to build the world's first thinking robot. This is not science fiction:some say they will have made it by the year 2020. Carol Packer reports.
Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (机器人) which scientists have built at the Massachusetts Institute of Technology (MIT). Kismet is different from the traditional robot because it can show human emotions. Its eyes, ears and lips move to show when it feels happy, sad or bored.Kismet is one of the first of a new generation of androids -- robots that look like human beings---which can imitate human feelings. Cog, another android invented by the MIT,imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old.
The optimists (乐观主义者) say that by the year 2020 we will have created humanoids (机器人) with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public.What kind of jobs will they do? In the future, robots like Robonaut, a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertain us by dancing and playing the piano.
Some people worry about what the future holds: will robots become monsters (怪物)?Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers, connected to the Intemet in the future.People will have micro-chips in various parts of their body, which will connect them to a wide variety of .gadgets (小装置). Perhaps we should not exaggerate (夸大)the importance of technology, but one wonders whether, in years to come, we will still be falling in love, and whether we will still feel pain. Who knows?
第 31 题 Kismet is different from traditional robots because
A. it thinks for itself.
B. it is not like science fiction.
C. it can look after two-year-olds.
D. it seems to have human feelings.
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).
