問題詳情:
A new keyboard can tell whether you are its owner. The keyboard records information about the typing pattern(模式)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 everyone else, even if the person knows the password. What's more, this equipment needs no batteries. It collects all the energy it needs from your actions of 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(納米線)on their surface area, increasing the effective contact areas between the plastics and fingers. This guarantees 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 equipment. "It could also be applied to a touch screen, for example, "Dai says. " Then smart phones and notepads could collect energy from someone's actions of typing or drawing. "
"Future work might make the keyboard even more useful, "Dai adds. " A later design might build tiny capacitors onto the nanowires, "he suggests. Capacitors are little devices that temporarily store electric charge. Those might then be LEDs to light a keyboard in the dark.
Zhonglin Wang is a co-designer of the new keyboard. His team has built a working model of the keyboard. "If a company decides to fund(資助)its production, this keyboard could be in stores in as few as two years, "says Wang.

【分析】
本文是一篇説明文,介紹了一款新型的鍵盤。這種鍵盤通過將輸入模式與正確的用户進行匹配來識別它的主人。
101.細節理解題。根據第一段中的"The program then checks to see if the pattern matches the right user"可知,這種新型的鍵盤通過將輸入模式與正確的用户進行匹配,來識別它的主人,故選A。
102.細節理解題。根據第二段中的" But instead of being smooth, the keys have millions of tiny plastic …as someone types. "可知,鍵盤表面有數以百萬計的微小的塑料納米線,增加了塑料和手指之間的有效接觸區域,保*了人在打字時有足夠的能量運行鍵盤。這説明這些納米線是幫助產生能量的,故選D。
103.推理判斷題。根據第三段中的"Liming Dai,a scientist,did not work on the new keyboard,but he thinks the design could be important in getting better performance from a variety of equipment"可知Dai認為這種設計對於提高各種設備的*能很重要。由此推知,Dai對這個新型鍵盤持積極態度,故選C。
104.主旨大意題。本文為讀者介紹了一款新型的鍵盤,這種新型的鍵盤通過將輸入模式與正確的用户進行匹配來識別它的主人,所以這篇文章最好的題目是一款完全屬於你的鍵盤,故選B。
