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(偽裝) 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 這是一篇說明文,J.K.羅琳在她的大片《哈利•波特》中埋下了發(fā)明"隱形外套"的想法,如今科學家們通過不懈的努力,使之成為現(xiàn)實.它的用途很廣,不僅可以偽裝人,也可以隱藏建筑物.
解答 47.C.詞義推測題題.由劃線詞所在句子scientists have been falling all over themselves to create a material that can not only camouflage(偽裝) people,可知,科學家怎樣地研發(fā)一種能夠偽裝人們的材料.推測此處應當是盡力的意思,故選C.
48.A.細節(jié)理解題.由第一段末句的with a magical textile that it properly calls"Quantum Stealth"一個神奇的紡織品正確地稱之為"量子隱形,以及第二段the material makes its wearer completely invisible,even to people with night glasses.這種材料使它的穿著者完全看不見,甚至對于帶著夜視鏡的人.可知,它是一種可以使穿戴它的人變得不可見的材料.故選A.
49.D.段落大意題.由第三段可知,主要講述這種材料能隱身的原理及它的用途.故選D.
50.B.細節(jié)理解題.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,科學家需要進一步開發(fā)新一代的材料,以滿足需要.故選B.
