雅思阅读练习及答案：

Key and Explanations:

1. D

See Paragraph 3: ...Alex Mischenko, ofCambridge University. Using commercially availableparaelectric film, he and his colleagues havegenerated temperature drops...

2. C

See Paragraph 5: The first Pentium chips sold byDr Moore’s company, Intel, in 1993, ran at 60mcycles a second.

3. F

See Paragraph 8: ...Rama Venkatasubramanian, of Nextreme Thermal Solutions in NorthCarolina, claims to have made thermoelectric refrigerators that can sit on the back of computerchips and cool hotspots by 10℃. 4. E

See Paragraph 8: Ali Shakouri, of the University of California, Santa Cruz, says his are evensmaller梥o small that they can go inside the chip.

5. B

See Paragraph 9: To improve on this, IBM’s research laboratory in Zurich is experimentingwith tiny jets that stir the liquid up and thus make sure all of it eventually touches theoutside of the channel--the part where the heat exchange takes place.

6. TRUE

See Paragraph 2: ...paraelectric materials. These act like batteries when they undergo atemperature change: attach electrodes to them and they generate a current.

7. FALSE

See Paragraph 3 (That may be enough to change the phenomenon from a laboratorycuriosity to something with commercial applications. ) and Paragraph 4 (As to what thoseapplications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up acompany to pursue them. He foresees putting his discovery to use in more efficient domesticfridges? 8. FALSE

See Paragraph 5: Heat is released every time a logical operation is performed inside amicroprocessor, so the faster the processor is, the more heat it generates. Doubling thefrequency quadruples the heat output. 9. NOT GIVEN

See Paragraph 9: In the future, therefore, a combination of microchannels and eitherthermoelectrics or paraelectrics might cool computers.

10. D

See Paragraph 6: Tweaking the processor’s heat sinks ?has reached its limit. So hastweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems?also seems to have the end of the road in sight.

11. heat

See Paragraph 1: Today’s high-tech world, however, demands high-tech refrigeration. Heatpumps are no longer up to the job. The search is on for something to replace them.

12. paraelectric

See Paragraph 3: Using commercially available paraelectric film, he and his colleagues havegenerated temperature drops five times bigger than any previously recorded.

13. thermoelectric

See Paragraph 7: ...the thermoelectric effect. Like paraelectric materials, this generateselectricity from a heat source and produces cooling from an electrical source. Unlikeparaelectrics, a significant body of researchers is already working on it. 14. radiator

See Paragraph 9: The last word in computer cooling, though, may go to a system even lesstechy than a heat pump--a miniature version of a car radiator.
