2019-2020年高三英语一轮复习Unit1Greatscientists课时作业新人教版必修.阅读理解A(xx广西重点高中二模)People love cellphones, which is why nine ten Americans own one. But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years. A new study in rats now augments those concerns. Its data linked longterm, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain. The results have yet to be confirmed, the authors note.Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet. He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles. Still, he calls the new studys findings “significant”. They could lead to studies researching how cellphone radiation might cause cancer, he says.Phone signals are relayed between cell towers and cellphones via radio waves. This radio frequencyor RF radiation is a type known as nonionizing(非电离的). Unlike Xrays, nonionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation, such as Xrays. But that does not mean radio waves might not cause harm. In very large doses (量) this radiation will heat the body and cause tissue damage. But its not yet known what much lower RF levels might do, such as those from cellphone use. Five years ago, the World Health Organizations International Agency for Research on Cancer, or IARC, concluded that cellphone use “is possibly carcinogenic (致癌的)” .Its conclusion was based on what little research data was available at that time. But notice that IARC was not certain. It said only that phone use might “possibly” cause cancer. So scientists at the National Toxicology Program, or NTP, investigated further.【文章大意】本文是一篇说明文。人们喜欢用手机，90%的美国人都有手机。那么，过度使用手机是否会有患癌的风险呢？一项新的研究给出了一些线索。【难句分析】Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet.分析：本句为复合句。although引导让步状语从句。why such a link might exist为why引导的宾语从句，作介词to的宾语。译文：Jonathan Samet指出，事实上，尽管在老鼠身上进行的研究发现手机辐射和癌症之间有联系，但却没有提供线索表明这种联系为什么可能存在。1Which of the following can replace the underlined word “augments” ?Afigures out Bputs outCrefers to Dadds to答案与解析：D考查词义猜测。画线词前面提到过度使用手机是否有患癌的风险这一问题多年来引发的争议不断，再根据画线词后的“concerns”和“Its data linked longterm, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain”可知，现在一项在老鼠身上进行的新研究增加了那些忧虑。故画线词与adds to意义相近。2In which aspect does Jonathan Samet think the new study in rats is significant?AIt assists him with his teaching.BIt indicates a new research direction.CIt warns people to mind cellphone safety.DIt makes a breakthrough in cancer research.答案与解析：B考查推理判断。根据第二段中的“They could lead to studies researching how cellphone radiation might cause cancer, he says”可知，这项研究会促使科学家去查明手机辐射可能是怎样致癌的，也就是说它为科学家提供了一个新的研究方向。3What is Paragraph 3 mainly about?AHow phone signals are delivered.BHow cellphones produce radiation.CFeatures of radiation from cellphones.DDifferences between ionizing and nonionizing radiation.答案与解析：C考查主旨要义。根据第三段的内容尤其是“nonionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation.”可知，本段主要讲的是手机辐射的特点，它是非电离的，其危害性远低于电离辐射。4What might be the theme of NTP scientists further research?AWhy cellphone use causes cancer.BWhether cellphone use really causes cancer.CWhat health effects cellphone use has.DHow much exposure to cellphone radiation is safe.答案与解析：B考查推理判断。根据最后一段中的“It said only that phone use might possibly cause cancer. So scientists at the National Toxicology Program, or NTP, investigated further”可知，NTP的科学家进一步研究的主题可能是手机使用是否真的会导致癌症。B(xx济南模拟)A European Union program is letting blind people experience famous paintings for the first time. It uses threedimensional (3D) printing to recreate famous paintings so they can be touched.One painting printed with the new technology is Gustav Klimts “The Kiss”. It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman. Klimt finished the painting in 1908. Until now, people who had trouble seeing could not appreciate the artwork. But thanks to the reproduction they can touch the piece and feel the ridges and depressions. Andreas Reichinger started making 3D versions of artwork in xx. He said this reproduction was his most difficult project because the couples robes are so detailed. Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it she said，“Exactly, can you see these? There are so many details.”Raditsch said she could imagine what the original painting looks like when she touched the reproduction. “Its somehow round.You can feel it.You can feel it.It es with it.And in many places its so smooth.And then I think to myself: it probably shines too！”Raditsch said.The Belvedere is not the only museum to have 3D versions of its artwork. Some of the pieces at the Prado Museum, in Madrid, Spain have reproductions that can be touched. But the piece in Vienna has one special part: it is made with widely available 3D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.【文章大意】本文是一篇说明文。文章讲述了欧盟的一个项目使用3D打印技术重现名画，让它们可以被视障人士触摸到。5What is“The Kiss” ?AA European Union project.BA popular painting.CA 3D technology.DA famous museum.答案与解析：B考查细节理解。从文章第二段的“One painting printed with the new technology is Gustav Klimts The Kiss.

BPuzzled.CExcited. DNervous.答案与解析：C考查推理判断。从文章第四段中的“You can feel it. You can feel it”可以推测出Raditsch“激动的”心情。故选C项。8What is the best title for the text?A. A European Union Program for Museum VisitorsB3D Printing Lets the Blind Experience Famous PaintingsCHow to Reproduce the Worldfamous PaintingsDA Special Museum for Art Fans in Vienna，Austria答案与解析：D考查标题判断。从文章第一段的内容可以看出，用3D打印技术让视障人士体验名画是文章的中心，下文是围绕该话题展开介绍的。故选B项。A项错在“Museum Visitors”太宽泛；C项“如何复制世界名画”只是文章的一部分，不全面；D项没有突出“3D printing”和“blind fans”，故排除。.完形填空(xx长春七校第一次联考)Jake Olson lost his left eye when he was eight months old because of a born cancer. _1_ it was controlled through treatments, it reappeared and _2_ the loss of his right eye.
