[1]画线部分属于“主语＋be＋过去分词＋不定式”句型。其中“ discovered at... Sanxingdui ”为过去分词短语作定语，修饰statues。 [2]画线部分为现在分词结构作原因状语。其中“what the stars were”为what引导的宾语从句。 2 Our power to investigate and thus understand space changed dramatically when the first telescope was angled④ at the night sky，increasing as it did the power of the human eye and enabling us to understand that the universe is far larger than was previously imaginable⑤. [3] The planets were seen to be worlds ⑥similar to our own，many of them even having their own moons[4]．Soon，it was understood that the Sun was just one star among billions in the galaxy⑦ we call the Milky Way.Some 300 years later，we learnt that the Milky Way itself was just one galaxy among billions of others, spread across the blackness of space like great islands of light and matter⑧ floating in a vast cosmic⑨ ocean. [3]本句是一个主从复合句。“to investigate ...space”为不定式短语作后置定语，修饰Our power；“when the first...night sky”为when引导的时间状语从句；“ increasing ...human eye”和“enabling us... imaginable”是两个并列的现在分词结构作状语。“that the universe...imaginable ”为that引导的宾语从句，其中than引导比较状语从句，从句中省略了主语the universe。 [4]画线部分为独立主格结构，在句中作状语。 3 Almost 400 years after the first Earth­based telescope⑩ was invented, the Hubble Space Telescope was launched into orbit.Giving astronomers—indeed all of us—the first breathtakingly⑪ beautiful images of our universe taken from beyond Earth.Nothing in history has allowed us to see so much over such great distances, from enormous⑫ clouds of gas where stars are being born，to huge black holes，and even to new planets where we might conceivably⑬ find life.[5] Not only that—it has also helped us to work out the age and nature⑭ of the universe, and discover the incredible fact that the universe is expanding at an ever­increasing speed⑮. [5]本句中的两个where引导的从句均为定语从句，分别修饰gas和planets。 4 To see even further into the universe, many countries are now engaged in ⑯building ever more advanced⑰ telescopes.Currently, China operates⑱ the world's largest and most powerful radio telescope, the FAST telescope, completed in 2016.The 500­metre dish of the“Eye of Heaven”，as it is known， is being used in the search for dark matter，thought to be composed of⑲ subatomic particles⑳ invisibleeq \o(○,\s\up3(21)) to ordinary telescopes[6]．This vast dish also has the ability to explore regions of space billions of light yearseq \o(○,\s\up3(22)) away，right at the edge ofeq \o(○,\s\up3(23)) the visible universe. [6]“thought...telescopes ”为过去分词短语作后置定语，修饰dark matter。 5 The Hubble and the space telescopes constructed after it will allow us to see further and further into space.We will view stars and galaxies billions of light years away and look back at a past that was billions of years ago.Using ever­larger radio telescopes as our eyes，we will one day be able to look back toeq \o(○,\s\up3(24)) a time in the very early universe，before the existence of light.But the human quest foreq \o(○,\s\up3(25)) knowledge reaches even beyond that.So much of the universe remains unexplored that we are still close to the start of this incredible journey of discovery. 参考译文 眺望夜空的眼睛 1．从人类有史以来，夜空就一直是让人浮想联翩的不竭源头。例如在中国考古遗址三星堆发掘的古蜀国神秘的巨目铜像，古时的人们认为它能够看到遥远的星空。事实上，人类仅凭肉眼只能看到夜空很小的一部分。并且在很长一段时间里，人们都无法理解他们所看到的事物。古时的人们并不知道星星到底是什么，所以他们便凭着想象去创造了一个空中世界。 2．当第一台望远镜对准夜空时，我们探索进而理解太空的能力就发生了巨大变化，它不仅增强了人类肉眼观测的能力，而且也让我们明白宇宙要比之前想象的大得多。每个行星都可以被视为和我们地球类似的星球，其中许多行星甚至有它们自己的卫星。很快，我们明白太阳只不过是银河系中数十亿计的恒星中的一个。大约300年后，我们又得知，银河系只是数十亿个散落在黑色太空中的星系之一，就像漂浮在宇宙汪洋中的一座光与物质组成的大型岛屿。 3.第一个地基望远镜问世将近400年之后，哈勃空间望远镜发射入轨，不仅让宇航员，事实上还让我们所有人，都看见了来自地球之外令人叹为观止的宇宙美景。它让我们史无前例地看到了如此遥远的景观——从星体诞生的巨大气体云团，到巨型黑洞，甚至到可能会发现生命迹象的新行星。不仅如此，它还帮助我们测算宇宙的年龄并分析宇宙的本质，且发现了惊人的事实——宇宙正在以不断增加的速度扩大。 4．为了能更加深入地观察宇宙，很多国家开始投入研发更先进的望远镜。近来，中国研发了世界最大、功能最强的射电望远镜——FAST望远镜，于2016年建成。众所周知，这个被称为“天眼”的500米口径巨盘用于探寻暗物质。暗物质被认为由亚原子粒子组成，一般望远镜是观测不到的。这个巨盘还能探索数十亿光年之外的太空领域，那里是看得到的宇宙的边界。 5．哈勃望远镜以及在它之后建成的太空望远镜将使我们能看见更加遥远的太空。我们将能观察几十亿光年外的星体和星系，回看数十亿年之前的过去。终将有一天，我们会使用更巨大的射电望远镜，当作人类之眼，回看在光产生之前的宇宙的最早时期。但人类对知识的渴望不止于此。宇宙还有很多的未知领域，我们才刚刚接近这段奇幻发现之旅的起点。 Ⅰ.Reading for main idea Read the passage quickly and choose the best answer.
