since the start of human history．For example，the mysterious large-eyed，bronze statues of the ancient Shu Kingdom，discovered at the Chinese archeological② site at Sanxingdui，were believed to have been able to look across great distances into the stars．In reality③，humans can see very little of the night sky with the naked eye④．And，for a long while，people were unable to understand what they could see．[1] Not knowing what the stars were，people in ancient times used their imaginations to create a world in the sky． Period 5　课时练案 课文整体教学(Developing ideas) [1]Not knowing what the stars

angled⑧ 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 imaginable．The planets were seen to be worlds similar to our own，many of them even having their own moons．Soon，it was understood that the Sun was just one star among billions in the galaxy⑨ we call the Milky Way⑩．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 matter floating in a vast cosmic⑪ ocean． Period 5　课时练案

ideas) Almost 400 years after the first Earth-based telescope was invented，the Hubble Space Telescope was launched⑫ into orbit，giving astronomers—indeed all of us—the first breathtakingly⑬ beautiful images⑭ of our universe taken from beyond Earth．Nothing in history has allowed us to see so much over such great distances，[3]from enormous clouds of gas where stars are being born，to huge black holes，and even to new planets where we might conceivably⑮ find life．Not only that—it has also helped us to work out the age and nature of the universe，and [4]discover the incredible fact that the universe is expanding at an ever-increasing speed⑯． Period 5　课时练案 课文整体教学(Developing ideas) [3]句中的两个where引导的从句均为定语从句，分别修饰clouds of gas和planets。 [4]句中that引导同位语从句。 Period 5　课时练案 课文整体教学(Developing ideas) To see even further into the universe，many countries are now engaged in⑰ building ever more advanced telescopes⑱．Currently，China operates the world's largest and most powerful radio telescope，the FAST telescope，completed in 2016．The 500-metre dish of the “Eye of Heaven”，as it is known，is being used in the search for dark matter，thought to be composed of⑲subatomic particles⑳ invisible㉑ to ordinary telescopes．This vast dish also has the ability to explore regions of space billions of light years away，right at the edge of the visible universe． Period 5　课时练案 课文整体教学(Developing ideas) The Hubble and the space telescopes constructed㉒ 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 ever-larger radio telescopes as our eyes，we will one day be able to look back to a time in the very early universe，before the existence of light．But the human quest for㉓ 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． Period 5　课时练案 课文整体教学(Developing ideas) 眺望夜空的眼睛 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。 Period 5　课时练案 课文整体教学(Developing ideas) 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颗。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。 Period 5　课时练案 课文整体教学(Developing ideas) 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，不仅让天文学家，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。 Period 5　课时练案 课文整体教学(Developing ideas) 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。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。 Period 5　课时练案
