5、g damaged. The figure of 60 rems has been agreed on.篇章导读：本文是一篇说明文。太阳和其他星体发出的射线对人类既有利又有弊，那么大气层对此又是如何起作用的呢？人们能承受的安全射线数是多少雷姆呢？1A.for Bwith Con Das答案：Dact as “充当，起作用”。句意：大气层再次对我们起到防护的作用。2A.stars Bsun Cearth Dspace答案：C由上题可知，大气层起到防护的作用，保护的应该是地球。故选C项。3A.with Bfrom Cunder Dfor答案：Dbe essential for “对来说是首要的/基
6、础的”，为固定搭配。4A.use Blive Ceat Dget答案：C由常识可知，植物依靠阳光来生长出我们吃的食物，故选C项。5A.again Balso Cbesides Dtoo答案：Dalso一般紧跟动词；besides一般用在句首；too可用在句中，用逗号隔开。此处指热量也使得我们的生活环境温度适宜。6A.environment Bspace Catmosphere Dearth答案：C由第1空所在的句子可知，地球周围有大气防护层，因此推知这里紫外线穿透大气层。故选C。7A.across Bto Cfrom Dthrough答案：D这里的come through相当于penetrat
7、e“穿透”。come across “偶遇”；come to “来到”；come from “来自”。句意：各类来自外太空的宇宙射线穿透大气层。故选through。8A.valid Benormous Cvarious Dproper答案：B由空格前but表转折和句末的“are screened off (被隔开)”可判断此处表述大量的来自太阳的辐射被隔离掉了。valid “有效的”；various “各种各样的”；proper “合适的”。enormous “大量的”符合文意。9A.As soon as BAs well as CAs much as DAs possible as答案：Aa
8、s soon as “一就”。此处表述人一离开大气层就会接触到射线。故选A项。10A.shown Bexposed Cfaced Dcovered答案：Bbe exposed to “暴露于”，符合语意。11A.but Bbecause Cso Dso that答案：A本句前半句的意思：人一离开大气层就会接触到射线；后半句的意思：他们的太空服和太空船的外壁会阻止射线造成的损害。前后应该是转折关系，故用but。12A.get Bmake Chave Ddo答案：D“do动词原形”结构强调谓语动词。13A.Mars Batmosphere Cspace Dplanet答案：C由Radiation和
9、explorers可推测，应选space (太空)。句意：射线是探险者在太空中所知的最大危险。14A.pieces Bunits Cparts Dsystems答案：B此处表述射线的剂量可用“雷姆”这个测量单位来测量，故选B项。15A.receive Baccept Cbring Dcatch答案：A由第16空所在句子中的“radiation that we receive each year”可知，此处表示受到辐射，故选A项。16A.conventional Bcommon Cgeneral Dnormal答案：D此处表述我们每年接受的正常辐射量大约为2毫雷姆。故选normal。17A.pu
10、zzles Bfloats Ccombines Dchanges答案：D由句意“所处地点不同，所能承受的正常的辐射量也不一样”可确定答案为D项。18A.what Bwhich Cthat Dwhy答案：C本句应填入引导宾语从句的连接词，而从句不缺少成分和语意，故选择that。19A.put up with Bkeep up with Ccome up with Dcatch up with答案：A此处表述人类可承受的辐射量。put up with “忍受”，符合语境。20A.from Bthan Cas Daway答案：B由前面的“more”和后一句中的“The figure of 60 re
11、ms”可知，应选than，表示“远超0.1雷姆的辐射量”。阅读理解AEdmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets (彗星) which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could ot
12、her scientists who dealt with such problems.However, Halley had a friend named Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem，but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellip
13、se (椭圆)Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart.This seemed
14、very strange to Halley. The different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back ag
15、ain.It was an astonishing idea! Halley felt certain enough to make a prediction of what comet would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halleys prediction could be tested. In 1758 the comet appeared in the sky. Halley did n

Ever since then that comet has been called Halleys comet, in his honorp2.1Halley made his discovery _.Aby doing experimentsBby means of his own careful observationCby using the work of other scientistsDby chance答案：C细节理解题。由文章第一段第二句及第三段第二、三、四句“He figured o
17、ut the orbits of some of the comets that had been observed by scientists.He made a surprising discovery.The comets that had appeared in the years 1531,1607，and 1682 all had the same orbit.”可知应选C。2Halley made a surprising，but correct prediction in the year _. A1704 B1705 C1706 D1707答案：B细节理解题。由第五段第三、四
18、句“He decided that this comet would appear in the year 1758. There were 53 years to go before Halleys prediction could be tested.”可知，他预言彗星出现的时间是1758年，而这个预言还要经过53年才能验证，由此可以计算出哈雷得出这个预言的时间是1705年。3This passage in general is about _.AHalley and other scientistsBthe orbit of a cometCNewton and HalleyDHalle
19、y and his discovery答案：D主旨大意题。文章的中心大意就是哈雷以及他的发现。4What can we infer from the text?AEdmund Halley was an American scientist.BHalley made his discovery by doing experiments.CNewton was a famous mathematician.DThe orbit of a comet had the shape of a circle.答案：C推理判断题。从文章首句可知A项错误；从第1题的分析中可知B项也错误；牛顿告诉哈雷彗星的轨
20、道是椭圆形的，可排除D。1astonishing adj. 令人惊讶的2prediction n. 预言1figure out 解决；计算出2in sb.s honor 向某人致敬B“Hello, Earth! Can you hear me？” Thats the voice more than 400,000 people received recently. It was from Philae, a space vehicle that landed on a comet in 2014. However, its transmissions (传送信号) back home went
21、 silent since then.It took a long time for Philae to make its way across the solar system and reach comet 67P/CG. The space vehicle got there aboard the Rosetta probe (探测器), which has been circling around the comet since Philae separated from it in November, 2014. Philaes job was to collect material
22、s to study the comets composition. And for about two and a half days after landing, it did just that, sending the information back to scientists on Earth. But Philaes landing on the comets icy surface had not been smooth. While touching down, it jumped up and ended up in the shadow of something like
23、 a huge rock. Philae runs on solar power, but there was no light in the place where it landed. In the end, it failed to work. However, as comet 67P/CG moved closer to the sun, more sunlight reached the space vehicle, allowing it to power up and come back online. Philae then sent something to Rosetta
24、, which passed on the information back to Earth.“We only received the information for about 85 seconds, but thats enough to let us know it is alive and well，” says Stephan Ulamec, who works for the European Space Agency.“We hope to work out where it landed exactly on the 4kilometerwide comet. Now we
25、 plan to change how Rosetta moves so that Philae can keep on communicating and receiving instructions.”5Hearing Philaes voice，those people must have felt _. Aafraid Bcalm Cexcited Dworried答案：C推理判断题。由第一段中的“Philae . landed on a comet in 2014. However, its transmissions (传送信号) back home went silent sin
26、ce then.”可知，Philae于2014年着陆彗星后就失联了，所以当人们再次听到它传来的声音时一定很兴奋，故选C项。6According to the text, Philae _.Awas damaged when it landedBmoved around comet 67P/CGCneeds light and gas to keep workingDhelps scientists learn about a comet答案：D细节理解题。由第三段首句“Philaes job was to collect materials to study the comets compos
27、ition.”可知，Philae的任务是帮助科学家了解一颗彗星的相关情况，故选D项。7What Stephan says in the text suggests that _. ARosetta will move around another comet BPhilae will continue to work for scientists Cmost comets are as wide as four kilometers Dhe wonders whether Philae is still alive答案：B细节理解题。由最后一段尾句“Now we plan to change
28、how Rosetta moves so that Philae can keep on communicating and receiving instructions.”可知，Philae将会继续为科学家们服务，故选B项。8What does the author mainly talk about in the text?AA sleeping space vehicle wakes up.BIt is very dangerous to travel in space.CA new comet was discovered recently.DPhilae was sent into
29、space successfully.答案：A主旨大意题。总览全文可知，文章主要介绍了彗星着陆器Philae的一些情况。它在“沉睡”了好久之后“醒”了过来，并向地球发出了信息。1composition n. 成分；构成 2.instruction n. 命令；指示1make ones way 行进；前进2end up 最终处于，以而告终七选五根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。If something that youre doing doesnt challenge you, then it doesnt change you.
