Researchers from Georgia Tech say that they have come up with a low-cost device (装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence (节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses.
These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by extension, whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right.
It also doesn't require a new type of technology that people aren't already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch”four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
21. Why do the researchers develop the smart keyboard? A. To reduce pressure on keys. C. To replace the password system.
B. To improve accuracy in typing D. To cut the cost of e-space protection.
22. What makes the invention of the smart keyboard possible？
A. Computers are much easier to operate. B. Fingerprint scanning techniques develop fast. C. Typing patterns vary from person to person. D. Data security measures are guaranteed. 23. What do the researchers expect of the smart keyboard？ A. It'll be environment-friendly. C. It'll be made of plastics
24. Where is this text most likely from?
A. A diary. B. A guidebook C. A novel. D. A magazine. B
We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product through -out its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. \replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house,\said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.
So what's the solution? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%. 25. What does the author think of new devices?
A. They are environment-friendly. B. They are no better than the old.
B. It'll reach consumers soon. D. It'll help speed up typing.
C. They cost more to use at home. D. They go out of style quickly. 26. Why did Babbitt's team conduct the research?
A. To reduce the cost of minerals. B. To test the life cycle of a product.
C. To update consumers on new technology. D. To find out electricity consumption of the devices. 27. Which of the following uses the least energy?
A. The box-set TV. B. The tablet. C. The LCD TV. D. The desktop computer. 28. What does the text suggest people do about old electronic devices?
A. Stop using them. B. Take them apart. C. Upgrade them. D. Recycle them.

Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes (糖尿病),Thomas would need to inject himself with insulin (胰岛素) three times a day for the rest of his life or risk nerve damage, blindness and even death. And if that weren't bad enough, he had no health insurance.
After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton,Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rock star, and created diabeticrockstar.com, a free online community fordiabetics and their loved ones — a place where over 1 100 people share personalstories, information and resources.
Jason Swencki'sson, Kody, was diagnosed with diabetes at six. Father and son visit the online children's forums(论坛) together most evenings.“Kody gets so excited, writing to kids from all over，” says Swencki, one of the site's volunteers.“They know what he's going through, so he doesn't feel alone.”
Kody is anything but alone; Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.
These days,Thomas's main focus is his charity (慈善机构), Fight It, which provides medicine sand supplies to people — 225 to date — who can't afford a diabetic's huge expenses. Fight－it org, has raised about $23 000 — in products and in cash. In May, Thomas will hold the first annual Diabetic Rock star Festival in the Caribbean.
Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full time job waiting tables. “Of the diabetes charities out there,most are putting money into finding a cure，” says Bentley Gubar, one of Rock star's original members. “But Christopher is the only person I know saying people need help now.”

It is reported that in the near future robots and humans will probably work together to create jazz. A singing robot is being taught to create jazz with human beings in a project.
Antonio Chella from Italy is working with a Telenoid robot. To start with, the Telenoid robot will be trained to imitate (模仿) the movements and simple sounds made by a human singer, and then connect music with different human emotions.
Precious (以前的) robots had the ability to find common connections between things. But Chella suggests that conscious (有意识的) robots should be able to go a step further and find new connections.
The Telenoid robot is of this kind. This work raises interesting questions about the connection between consciousness and music creating. ” says Philippe Pasquier. A musician needs a physical body.
Pasquier argues that the robot musician is faced with a big challenge. \software has already been developed and it can imitate The Beatles, a famous band. However, what made The Beatles famous were not only their songs but their wonderful performance of the songs, \
It is not clear how a robot would perform music in a new way. But by imitating humans, the Telenoid robot could provide some useful information. What is important is that human musicians often listen to and compare music made by others for a long time before creating music of their own. So the Telenoid robot had better listen to more jazz music first? 32. What will the Telenoid robot be taught to do first? A. Communicate with human beings B. Connect music with human emotions C. Live and work comfortably with human beings
D. Imitate the movements and simple sounds of a human singer
