2、 THE NIGHT1 The night sky has been an endless source of fascination since the start of human history.For example,the mysterious large-eyed,bronze statues of the ancient Shu Kingdom,discovered at the Chinese archeological site at Sanxingdui,were believed to have been able to look across great distanc

3、es into the stars.In reality,humans can see very little of the night sky with the naked eye.And,for a long while,people were unable to understand what they could see.Not knowing what the stars were,people in ancient times used their imaginations to create a world in the sky.Now read the passage and

4、check your prediction.2 Our power to investigate and thus understand space changed dramatically when the first telescope was angled 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 planet

6、cross the blackness of space like great islands of light and matter floating in a vast cosmic ocean.3 Almost 400 years after the first Earth-based telescope was invented,the Hubble Space Telescope was launched into orbit,giving astronomers-indeed all of us-the first breathtakingly beautiful images o

7、f our universe taken from beyond Earth.Nothing in history has allowed us to see so much over such great distances,from enormous clouds of gas where stars are being born,to huge black holes,and even to new planets where we might conceivably find life.Not only that-it has also helped us to work out th

8、e age and nature of the universe,and discover the incredible fact that the universe is expanding at an ever-increasing speed.4 To see even further into the universe,many countries are now engaged in building ever more advanced telescopes.Currently,China operates the worlds largest and most powerful

9、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 of subatomic particles invisible to ordinary telescopes.This vast dish also has the ability to explore regions of space billi

10、ons of light years away,right at the edge of the visible universe.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 e

11、ver-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 for knowledge reaches even beyond that.So much of the universe remains unexplored that we are still close to the start of this incredibl

12、e journey of discovery.What does“eyes”refer to?The“eyes”not only refer to the mysterious large-eyed,bronze statues of the ancient Shu Kingdom,the Hubble Space Telescope and the FAST telescope,but also refer to the great human spirit of exploration.Read the passage and divide it into parts,then summa

13、rise the main idea of each part.Part 1 Paragraph 1The way of understanding the night sky in ancient times.Part 2 Paragraphs 24The development of the telescope and the development of understanding the space.Part 3 Paragraph 5There will be a long and incredible journey of space exploration.The order i

19、impression on you?3 In what different ways do the two reading passages in this unit reflect the spirit of exploration?4 Have you ever used a telescope or been to a planetarium?Share your experience with the class.3 The first passage is about the Challenger disaster.Although it was a tragedy,people d

20、id not stop exploring space.This shows that people will always seek to explore,even if some lose their lives in doing so.The second passage is about the development of the telescope,and how it reflects our desire to explore the unknown.Unlike the exploration conducted by astronauts such as those in

21、the Challenger,the exploration in the second passage was conducted by people located on Earth,at no personal risk.Nonetheless,the knowledge gained from telescopes is immense.The passages show that there are different ways of exploring the universe and gaining knowledge.4Work in groups.Give a talk ab

23、as with the class.Now think about how well you contributed to the group discussion and what you could do to improve.Language points 1.Not knowing what the stars were,people in ancient times used their imaginations to create a world in the sky.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。Not knowing what the

24、 stars were是现在分词结构作原因状语，置于句首。e.g.Believing the story,he kept on searching for further proof.因为相信这个故事，他继续寻找进一步的证据。2.Our power to investigate and thus understand space changed dramatically when the first telescope was angled at the night sky,increasing as it did the power of the human eye and enabling

25、 us to understand that the universe is far larger than was previously imaginable.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发生了巨大的变化,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。(1)when引导时间状语从句，increasing和enabling为现在分词短语作伴随状语，as it did为as引导的方式状语从句，that引导宾语从句，比较级than后面为省略的比较状语从句，省略了主语the universe，其完全形式为“the universe was prev

26、iously imaginable”。(2)v.斜移，斜置 angle for sth.转弯抹角地打听；博取 e.g.He angled his chair so that he could sit and watch her.他斜移了椅子，以便坐着观察她。She was angling for sympathy.她有意博取同情。n.角；角度；立场 at an angle 倾斜地，成一定角度地 from a(n).angle 从角度 e.g.The picture was hanging at an angle.画斜挂着。The rising sun is especially beautif

27、ul to look at from this angle.正在升起的太阳从这个角度看特别美。3.Soon,it was understood that the Sun was just one star among billions in the galaxy we call the Milky Way.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。(1)本句中的it是形式主语，而that the Sun was just one star among billions in the galaxy we call the Milky Way是真正的主语。这种语法现象在英语中很常见

28、。e.g.It is widely known that Earth goes round the Sun.众所周知，地球绕着太阳转。(2)we call the Milky Way为定语从句，修饰先行词galaxy。4.Nothing in history has allowed us to see so much over such great distances,from enormous clouds of gas where stars are being born,to huge black holes,and even to new planets where we might

29、conceivably find life.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。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。5.Not only that-it has also helped us to work out the age and nature of the universe,and discover the incredible fact that the universe is expanding at an ever-increasing speed.不仅如此，它

30、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。(1)that引导同位语从句，作fact的同位语。(2)at a(an).speed 以的速度 e.g.His money was running out at an alarming speed.他的钱用得很快，速度惊人。6.To see even further into the universe,many countries are now engaged in building ever more advanced telescopes.为了能更深入地观察宇宙，很多国家开始投入研发更先进的望远镜。

31、(1)To see even further into the universe为不定式短语作目的状语。(2)be engaged in(doing)sth.从事于，忙于 =engage oneself in(doing)sth.e.g.He wants to be engaged in foreign trade.=He wants to engage(himself)in foreign trade.他想要从事外贸工作。【归纳拓展】be engaged to sb.和订婚 engage in 参与，参加 engage sb.to do sth.雇用某人做某事 engagement n.订婚

32、；约会；雇用7.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 of subatomic particles invisible to ordinary telescopes.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。(1)as it is known为as引导的非限制性定语从句，thought to be composed o

33、f subatomic particles invisible to ordinary telescopes为过去分词短语作后置定语，修饰dark matter。(2)be composed of 由组成。e.g.All living things are composed of cells.所有的生物都由细胞组成。8.But the human quest for knowledge reaches even beyond that.但人类对知识的追求远不止于此。the/ones quest for 对的追求/探索 e.g.the quest for happiness/knowledge/

34、truth 对幸福/知识/真理的追求 My quest for a better bank continues.我继续在搜寻一家更好的银行。【归纳拓展】in quest of sth.寻找某物 e.g.He went off in quest of food.他外出寻找食物去了。9.So much of the universe remains unexplored that we are still close to the start of this incredible journey of discovery.宇宙还有很多未知领域，我们才刚刚接近这段奇幻发现之旅的起点。本句中含有由so

35、.that引导的结果状语从句。so.that和such.that都可以引导结果状语从句，二者的不同之处在于so修饰形容词或副词，such修饰名词或名词短语。e.g.So amazing was his voice that the singer attracted many passers-by.那位歌手的声音如此美妙，以至于他吸引了许多路人。The teacher gave the children such wonderful picture books that they got wild with joy.老师给了孩子们这么棒的图画书，他们高兴得不得了。课堂总结课堂总结Retelling EYES UPON THE NIGHTPart 1 Paragraph 1The way of understanding the night sky in ancient times.Part 2 Paragraphs 24The development of the telescope and the development of understanding the space.Part 3 Paragraph 5There will be a long and incredible journey of space exploration.
