A new keyboard can tell whether you are its owner. The keyboard records information about the typing pattern and sends it to a computer program. The program then checks to see if the typing pattern and sends it to a computer program. The program then checks to see if the pattern matches the right user, If not, an alarm sounds, and the computer locks the typist out. It locks out anyone else, even if than person knows password. What’s more, this device needs no batteries. It harvests all the person knows your password. What’s more, this device needs no batteries. It harvests all the energy it needs from the action of your typing. Besides, the keyboard is also self-cleaning and the keys are free of damage from water, oil and dirt.
The keys of the new keyboard are made of the same inexpensive plastic that might be found on any other standard keyboard. But instead of being smooth, the keys have millions of tiny plastic nanowires(纳米线)on their surface area to every key, increasing the effective contact area between the plastics and fingers. This ensures that there’s enough power to run the keyboard as someone types.
Liming Dai, a scientist, did not work on the new keyboard, but he thinks the design could be important in getting better performance from a variety of devices. “It could also be applied to a touch screen, for instance,” Dai says. “Then smartphones and notepads could harvest energy from the action of someone typing or drawing.”
“Future work might make the keyboard even more useful,” Dai adds. “A later design might build tiny capacitors(电容器)onto the nanowires,” he suggests. Capacitors are little devices that temporarily store electric charges. Those might then LEDs to light a Keyboard in the dark.
Zhonglin Wang is a co-designer of the new keyboard. His team has build a working model of the keyboard. “If a company decides to fund(投资)its production, this keyboard could be in stores in as little as two years,” says Wang.

答案：1.A; 2.D; 3.C; 4.B
解析：1.细节理解题。由第一段第二、三句“The keyboard records information about the typing pattern and sends it to a computer program. The program then checks to see if the pattern matches the right user. ”可知,这种新的键盘通过将输入模式和正确用户的输入模式进行匹配来识别它的主人,故选A项。
2.细节理解题。由第二段末句“This ensures that there’s enough power to run the keyboard as someone types."可知,键盘表面有许多纳米线是用来帮助产生电力的,故选D项。
3.推理判断题。由第三段中的“Liming Dai, a scientist,did not work on the new keyboard, but he thinks the design could be important in getting better perfonnance from a variety of devices. "可推断出,他对这个新型键盘持积极态度,故选C项。
4.主旨大意题。本义为读者介绍了一款新型的键盘,这种新的键盘通过将输入模式和正确用户的输入模式进行匹配来识别它的主人,所以这篇文章最好的题目是“ 一款完全属于你的键盘”,故选B项。
