1.Ever since J.K.Rowling planted the idea of an invisibility coat in her blockbuster(大片) Harry Potter book series,scientists have been falling all over themselves to create a material that can not only camouflage(伪装) people,but also camouflage buildings.Now a Canadian company claims to have won that race with a magical textile that it properly calls"Quantum Stealth".
British Columbia based Hyperstealth Technology Corporation claims that the material makes its wearer completely invisible,even to people with night glasses.Also,just like the young wizard's coat,it is lightweight and does not need cameras,batteries,lights or mirrors to operate.But best of all,it is cheap to manufacture!
So how does it really work?Well that is a top secret.Besides stating that they have successfully managed to bend light waves,so that they go around the material instead of through it,the company is not giving out any details.What it does detail is all the good uses'Quantum Stealth'could be put to-Ranging from protecting US and Canadian soldiers forced to step into enemy region,to allowing special armed forces to carry out surprise attack without any fear of being seen.And if that is not enough they even imagine creating aircrafts and submarines that can go completely undetected.
To prove that Quantum Stealth really exists,the company has released photos and even a video showing its magical properties.For those that are still skeptical,they have only one thing to say-Both the US and Canadian Military officials have witnessed it live and are so impressed that they are now working with Hyperstealth Technology to create the next generation'survival blanket'that could make the soldier invisible all at once!If this is indeed true,we have only one question-When will this magical fabric be available to the rest of us?

分析 这是一篇说明文,J.K.罗琳在她的大片《哈利•波特》中埋下了发明"隐形外套"的想法,如今科学家们通过不懈的努力,使之成为现实.它的用途很广,不仅可以伪装人,也可以隐藏建筑物.
解答 47.C.词义推测题题.由划线词所在句子scientists have been falling all over themselves to create a material that can not only camouflage(伪装) people,可知,科学家怎样地研发一种能够伪装人们的材料.推测此处应当是尽力的意思,故选C.
48.A.细节理解题.由第一段末句的with a magical textile that it properly calls"Quantum Stealth"一个神奇的纺织品正确地称之为"量子隐形,以及第二段the material makes its wearer completely invisible,even to people with night glasses.这种材料使它的穿着者完全看不见,甚至对于带着夜视镜的人.可知,它是一种可以使穿戴它的人变得不可见的材料.故选A.
49.D.段落大意题.由第三段可知,主要讲述这种材料能隐身的原理及它的用途.故选D.
50.B.细节理解题.由最后一段they are now working with Hyperstealth Technology to create the next generation"survival blanket"that could make the soldier invisible all at once!可知,科学家需要进一步开发新一代的材料,以满足需要.故选B.
