New technology may help cool it, and give information technology a unique twist, says Jairo Sinova, a professor. Laptops are getting increasingly powerful, but as they get smaller they are heating up, and dealing with the excessive heat has become a headache, Sinova explains? “The heart of the problem is the way information is processed, ” Sinova notes. “Laptops and some other devices use flows of electricity to process information, and thereby also produce heat. Theoretically, excessive heat could melt the laptop, and also wastes considerable energy. ” Sinova，s research is on an alternate way to process information. “Our research looks at the spin（旋转）of eloctrons（电子），tiny particles that naked eyes cannot detect, ” he explains. “The directions they turn can be used to record and process information. ” To process information, Sinova says, it is necessary to create information, transmit the information, and finally read it. The question is, can we change the way thi s i s done? “The device we' ve designed arranges the el ectrons according to spin together with the infooiation we want to process. We then transmit the electrons to another place in the device but with the spin still surviving, and finally are able to me.asure the direction of their spin throug h a voltage （电 压）that they produce, ” Sinova explains. The biggest challenge to create a s pin based device was the distance the electrons could travel while still keeping their spin?“Transmission is no problem now. Whereas before the limit was several hundred feet, with our device information can easily be transmitted hundreds of miles, ” he says. “This new device, as the only spin based device for infonnation processing, has a lot of real practical pote nt ial, ” he says. “One huge adva nt age is that i t is operational at room temperature, which nobody had been able to achieve until now. It may lead to a new and more efficient way to process information. n 1. To deal with hot laptops, we need to _ ? A. make them smaller B? protect them with special materials C? find a new way to process information D? speed up the movement of electrons 2. What can we 1 earn about Sinos device? A.

From the last paragraph we can infer that _ ? A. laptops can only be used at room temperature B. the new device has not yet been put to practical use C. 1aptops are the most efficient way to process information D. 1aptops function best indoors 4. What might be the most suitable title for the text? A. New Laptops Can Be Used to Fry Eggs B. New Laptops Waste No Enorgy C- New Technology May Cool the Laptop D.
