单选题 Digital Jewelry A. Jewelry is worn for many reasons—for aesthetics, to impress others, or as a symbol of affiliation or commitment. Basically, jewelry adorns the body, and has very little practical purpose. However, researchers are looking to change the way we think about the beads and bobbles we wear. In the next wave of mobile computing devices, our jewelry might double as our cell phones, personal digital assistants (PDAs) and GPS receivers. The combination of shrinking computer devices and increasing computer power has allowed several companies to begin producing fashion jewelry with embedded intelligence. Today, manufacturers can place millions of transistors on a microchip, which can be used to make small devices that store tons of digital data. Give me a ring B. Soon, cell phones will take a totally new form, appearing to have no form at all. Instead of one single device, cell phones will be broken up into their basic components and packaged as various pieces of digital jewelry. Each piece of jewelry will contain a fraction of the components found in a conventional mobile phone, according to IBM. Together, the digital-jewelry cell phone should work just like a conventional cell phone. Various components are inside a cell phone: microphone, receiver, touchpad, display, circuit board, antenna and battery. C. IBM has developed a prototype of a cell phone that consists of several pieces of digital jewelry that will work together wirelessly, possibly with Bluetooth wireless technology, to perform the functions of the above components. D. The following are the pieces of IBM's computerized-jewelry phone and their functions. Earrings—Speakers embedded into these earrings will be the phone's receiver. Necklace—Users will talk into the necklace's embedded microphone. Ring—Perhaps the most interesting piece of the phone, this 'magic decoder ring' is equipped with light-emitting diodes (三极管) (LEDs) that flash to indicate an incoming call. It can also be programmed to flash different colors to identify a particular caller or indicate the importance of a call. Bracelet—Equipped with a video graphics array (VGA，视频图形阵列) display. This wrist display could also be used as a caller identifier that flashes the name and phone number of the caller. E. With a jewelry phone, the keypad and dialing function could be integrated into the bracelet, or else dumped altogether—it's likely that voice-recognition software will be used to make calls, a capability that is already commonplace in many of today's cell phones. Simply say the name of the person you want to call and the phone will dial that person. IBM is also working on a miniature rechargeable battery to power these components. F. In addition to changing the way we make phone calls, digital jewelry will also affect how we deal with the ever- Increasing bombardment of e-mail. Imagine that the same ring that flashes for phone calls could also inform you that e-mall is piling up in your in-box. This flashing alert could also indicate the urgency of the e-mail. Of mice and monitors G. Two of the most identifiable components of a personal computer are the mouse and monitor. These devices are as familiar to us today as a television set. However, in the next decade, we could witness the disappearance of these devices, at least in their current form. Several companies, including IBM and Charmed Technology, are working on ways to create a head-mounted display. IBM is also working to shrink the computer mouse to the size of a ring and create a wrist-worn display. H. The mouse-ring that IBM is developing will use the company's TrackPoint technology to wirelessly move the cursor (光标) on a computer-monitor display. You're probably most familiar with TrackPoint as the little button embedded in the keyboard of some laptops. IBM researchers have transferred TrackPoint technology to a ring, which looks something like a black-pearl ring. On top of the ring is a little black ball that users will rotate to move the cursor, in the same way that the TrackPoint button on a laptop is used. I. This TrackPoint ring will be very valuable when monitors shrink to the size of watch face. In the coming age of ubiquitous (无处不在的) computing, displays will no longer be tied to desktops or wall screens. Instead, you'll wear the display like a pair of sunglasses or a bracelet. Researchers are overcoming several obstacles facing these new wearable displays, the most important of which is the readability of information displayed on these tiny devices. J. While IBM is in a stage of development, Charmed Technology is already marketing its digital jewelry, including a futuristic-looking eyepiece display. The eyepiece is the display component of the company's Charmed Communicator, a wearable, wireless, broadband-Internet device that can be controlled by voice, pen or handheld keypad. The company says that the device could be ready for the mainstream market by the end of 2001 or early 2002. The Communicator can be used as an MP3 player, a video player and a cell phone. The Java Ring K. It seems that everything we access today is under lock and key. Even the devices we use are protected by passwords. It can be frustrating trying to keep with all of the passwords and keys needed to access any door or computer program. Dallas Semiconductor is developing a new Java-based, computerized ring that will automatically unlock doors and log in to computers. L. The Java Ring, first introduced at Java One Conference, has been tested at Celebration School, an innovative K-12 school just outside Orlando, FL. The rings given to students are programmed with Java applets that communicate with host applications on networked systems. Applets are small applications that are designed to be run within another application. The Java Ring is snapped into a reader, called a Blue Dot receptor, to allow communication between a host system and the Java Ring. M. The Java Ring is a stainless-steel ring, 16-millimeters (0.6 inches) in diameter, which houses a 1-million-transistor processor, called an iButton. The ring has 134 KB of RAM, 32 KB of ROM, a real-time clock and a Java virtual machine, which is a piece of software that recognizes the Java language and translates it for the user's computer system. N. At Celebration School, the rings have been programmed to store electronic cash to pay for lunches, automatically unlock doors, take attendance, store a student's medical information and allow students to check out books. All of this information is stored on the ring's iButton. Students simply press the signet of their Java Ring against the Blue Dot receptor, and the system connected to the receptor performs the function that the applet instructs it to. In the future, the Java Ring may start your ear. O. Mobile computing is beginning to break the chains that tie us to our desks, but many of today's mobile devices can still be a bit awkward to carry around. In the next age of computing, we will see an explosion of computer parts across our bodies, rather than across our desktops. Digital jewelry, designed to supplement the personal computer, will be the evolution in digital technology that makes computer elements entirely compatible with the human form. (选自The Economist)

单选题The economy in the United States is heavily dependent on aluminum, a material widely used in the construction of buildings and in making such diverse things as cars, airplanes, and food containers. In 1979 Americans used over five million tons of new aluminum, and one and a half million tons of recycled aluminum. Some ninety percent of the bauxite (矾土) ore from which new aluminum is normally derived had to be imported, to meet the demand. Poorer ores are abundant in the United States, however, and researchers at Purdue University may recently have found a way to obtain aluminum magnetically from these. Although aluminum is not attracted by ordinary magnets, under special conditions it becomes temporarily "paramagnetic", or very weakly responsive to a magnetic field. This is achieved by immersing ore particles in water to which certain salts have been added and then filtering the ore through steel wool in the presence of a strong magnetic field. It is hoped that this technique will reduce the amount of high-grade aluminum the United States must import.

单选题Income inequality in the United State remained relatively stable for a period of nearly forty years. Beginning in the 1970's, however, this period of stability ended, as the first signs of widening income inequality became apparent. Over the course of the 1970's and 1980's , an increasingly clear trend toward greater income inequality emerged. By the end of the 1980's, the top 20 percent of workers were receiving the largest share of income ever recorded by government figures, and the bottom three fifths were receiving the lowest shares ever recorded. This trend has continued into the 1990's and currently shows no signs of decline. When the indicators of growing inequality were first observed in the 1970's, some researchers argued that the effects were merely temporary artifacts of short-term labor market disturbances. The new occupational structure appears to be one with an increase of well-paid technical, scientific and professional jobs at the top, a sliding middle class, and a growing poorly-paid service and retail jobs at the bottom. Several important labor-force changes appeared to be contributing to the shifting occupational structure. As occupational reconstructing and growing income inequality have become increasingly evident, a heated debate as to the causes and magnitude of these changes arose. Two dominant bodies of thought emerged around the issue: the job-skill mismatch thesis and the polarization thesis. Mismatch theorists argue that there is an increasing distance between the high skill requirements of post-industrial jobs and the inadequate training and mediocre qualifications of workers. They see the post-industrial economy leaving behind unskilled workers, especially women and minorities. For the mismatch theorist, the trend toward greater inequality is temporary arid will dissipate once the supply of workers acquires the skills demanded by a post-industrial economy. And they predict that the workers will experience an upgrading in their wages over the long run. Polarization theorists, on the other hand, believe that the rise in inequality is permanent, a result of the shift to a service-based economy. This vision of the postindustrial economy is characteristically polarized. The problem according to these theorists, is the type of jobs being generated in the new economy, not worker attributes. Because they believe the causes are structural and permanent, polarization theorists would deny the efficacy of public policies designed to educate and train unskilled workers. They predict a long-term continuation of the trend towards increasing income inequality. Studies show that the long-run increase in income inequality is also related to changes in the Nation's labor market and its household composition. The wage distribution has become considerably more unequal with more highly skilled, trained and educated workers at the top experiencing real wage gains and those at the bottom real wage losses. One factor is the shift in employment from those goods-producing industries that have disproportionately provided high-wage opportunities for low-skilled workers, towards services that disproportionately employ college graduates, and towards low-wage sectors such as retail trade. But within industry, shifts in labor demand away from less-educated workers are perhaps a more important explanation of eroding wages than the shift out of manufacturing. Also cited as putting downward pressure on the wages of less-educated workers are intensifying global competition and immigration, the decline of the proportion of workers belonging to unions, the decline in the real value of the minimum wage, the increasing need for computer skills, and the increasing use of temporary workers.
