Question

2．Raymond Wang，17，of Canada was awarded first place for a device that improves air quality on airplanes while cutting down the spreading of diseases at this year's Intel International Science and Engineering Fair （ISEF）．
According to Intel，Wang's system improves the quality of fresh air in a plane cabin by more than 190 per cent，while cutting diseases by up to 55 times，compared to conventional designs．Intel noted that Wang's invention could be easily and economically fixed into existing airplanes．
Two other teen researchers earned awards of﹩50，000 each at the event．One developed a technique to more quickly diagnose diseases caused by HIV．It's the virus responsible for AIDS．The other invented a device to more quickly shut down undersea oil spills．
"Intel believes young people are the key to future innovation and that in order to confront the global challenges of tomorrow，we need students from all backgrounds to get involved in science，technology and engineering，"says Wendy Hawkins，executive director of the Intel Foundation．"We hope these winners will inspire other young people to pursue their interest in these fields，"she says，"and apply their curiosity and creativity to the common good．"
This year's Intel International Science and Engineering Fair featured approximately 1，700 young scientists selected from more than 75 countries and regions．In addition to the top winners，600 finalists received awards and prizes for their innovative research．
The Intel International Science and Engineering Fair honours the world's most promising student scientists，inventors and engineers．Their projects are then evaluated online by nearly 1，000 judges from almost every scientific field．
The 2015 Intel ISEF is funded jointly by Intel and the Intel Foundation with additional awards and support from dozens of other academic，governmental and scientific organizations．This year，US﹩4 million was awarded．

25．Compared to traditional designs，Raymond Wang's systemB．
A．prevents oceans from oil pollution quickly
B．improves air quality on airplanes effectively
C．treats diseases happening on airplanes quickly
D．costs more but can be easily fixed into airplanes
26．For what purpose is Intel ISEF carried out？D
A．To inspire teenagers to challenge the authorities．
B．To persuade more teens to do good to the society．
C．To get more teens involved in computer exploring．
D．To encourage young people to get interested in science．
27．What do we know about 2015Intel ISEF？A
A．More than 30% of finalists receive awards and prizes．
B．Scientists all over the world compete for grand prizes．
C．Nearly 1000judges are present at the site of competition．
D．US4millionawardsandprizesareofferedbyIntelalone．

Answer 1

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了今年的英特尔国际科学与工程博览会精选了来自75多个国家和地区的约1700名年轻科学家，除了获奖者外，600名入围者获得了他们的创新研究奖和奖品；旨在告诉我们年轻人对未来的创新很重要，是应对全球挑战的明天的钥匙．

解答 25．B．细节理解题．根据文章第一段中的"Raymond Wang，17，of Canada was awarded first place for a device that improves air quality on airplanes…"以及第二段中的"Wang's system improves the quality of fresh air in a plane cabin by more than 190 per cent…"可知，Raymond Wang发明的装置改进了航空飞机上的空气质量，故获奖第一名；故选B．
26．D．细节理解题．根据文章第四段中的"We hope …will inspire other young people to pursue their interest in these fields…"可知，实施这项ISEF目的是吸引年轻人对此感兴趣；故选D．
27．A．推理判断题．根据文章第七段阐述"This year's Intel International Science and Engineering Fair featured approximately 1，700 young scientists selected from more than 75 countries and regions．In addition to the top winners，600 finalists received awards and prizes for their innovative research．"得知，这次博览会大约1700名年轻科学家中600多因他们的革新研究获奖．即是最终获奖的超过30%；故选A．

点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
