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.[1]not knowing what the stars were為動(dòng)詞-ing形式短語(yǔ)的否定形式,在句中作狀語(yǔ);what引導(dǎo)賓語(yǔ)從句,并在從句中作表語(yǔ)。[2]Our power to investigate⑤ and thus understand space changed dramatically⑥ when the first telescope⑦ was 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 cosmic ocean.[2]本句句子主干為our power to investigate and thus understand space changed dramatically,主語(yǔ)中心詞為our power,動(dòng)詞不定式作后置定語(yǔ);when引導(dǎo)時(shí)間狀語(yǔ)從句;第二個(gè)and連接并列的結(jié)果狀語(yǔ)。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 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 conceivably 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 speed .[3]句中的兩個(gè)where引導(dǎo)的從句均為定語(yǔ)從句,分別修飾gas和planets。[4]句中that引導(dǎo)同位語(yǔ)從句。To see even further into the universe,many countries are now engaged in building ever more advanced telescopes .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 of subatomic particles invisible 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.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 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 for 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.眺望夜空的眼睛從人類(lèi)有史以來(lái),夜空就一直是讓人浮想聯(lián)翩的不竭源頭。例如在中國(guó)考古遺址三星堆發(fā)掘的古蜀國(guó)神秘的巨目銅像,古時(shí)的人們認(rèn)為它能夠看到遙遠(yuǎn)的星空。事實(shí)上,人類(lèi)僅憑肉眼只能看到夜空很小的一部分。并且在很長(zhǎng)一段時(shí)間里,人們都無(wú)法理解他們所看到的事物。古時(shí)的人們并不知道星星到底是什么,所以他們便憑著想象去創(chuàng)造了一個(gè)空中世界。當(dāng)?shù)谝慌_(tái)望遠(yuǎn)鏡對(duì)準(zhǔn)夜空時(shí),我們探索進(jìn)而理解太空的能力就發(fā)生了巨大變化,它不僅增強(qiáng)了人類(lèi)肉眼觀測(cè)的能力,而且也讓我們明白宇宙要比之前想象的大得多。每個(gè)行星都可以被視為和我們地球類(lèi)似的星球,其中許多行星甚至有它們自己的衛(wèi)星。很快,我們明白太陽(yáng)只不過(guò)是銀河系中數(shù)十億計(jì)的恒星中的一顆。大約300年后,我們又得知,銀河系只是數(shù)十億個(gè)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與物質(zhì)組成的大型島嶼。第一個(gè)地基望遠(yuǎn)鏡問(wèn)世將近400年之后,哈勃空間望遠(yuǎn)鏡發(fā)射入軌,不僅讓天文學(xué)家,事實(shí)上還讓我們所有人,都看見(jiàn)了來(lái)自地球之外令人嘆為觀止的宇宙美景。它讓我們史無(wú)前例地看到了如此遙遠(yuǎn)的景觀——從星體誕生的巨大氣體云團(tuán),到巨型黑洞,甚至到可能會(huì)發(fā)現(xiàn)生命跡象的新行星。不僅如此,它還幫助我們測(cè)算宇宙的年齡并分析宇宙的本質(zhì),且發(fā)現(xiàn)了驚人的事實(shí)——宇宙正在以不斷增加的速度擴(kuò)大。為了能更加深入地觀察宇宙,很多國(guó)家開(kāi)始投入研發(fā)更先進(jìn)的望遠(yuǎn)鏡。近來(lái),中國(guó)研發(fā)了世界最大、功能最強(qiáng)的射電望遠(yuǎn)鏡——FAST望遠(yuǎn)鏡,于2016年建成。眾所周知,這個(gè)被稱(chēng)為“天眼”的500米口徑巨盤(pán)用于探尋暗物質(zhì)。暗物質(zhì)被認(rèn)為由亞原子粒子組成,一般望遠(yuǎn)鏡是觀測(cè)不到的。這個(gè)巨盤(pán)還能探索數(shù)十億光年之外的太空領(lǐng)域,那里是看得到的宇宙的邊界。哈勃望遠(yuǎn)鏡以及在它之后建成的太空望遠(yuǎn)鏡將使我們能看見(jiàn)更加遙遠(yuǎn)的太空。我們將能觀察幾十億光年外的星體和星系,回看數(shù)十億年之前的過(guò)去。終將有一天,我們會(huì)使用更巨大的射電望遠(yuǎn)鏡當(dāng)作人類(lèi)之眼,回看在光產(chǎn)生之前的宇宙的最早時(shí)期。但人類(lèi)對(duì)知識(shí)的渴望不止于此。宇宙還有很多的未知領(lǐng)域,我們才剛剛接近這段奇幻發(fā)現(xiàn)之旅的起點(diǎn)。Period

探求,探索EYES UPON THE NIGHTThe night sky has been an endless source of fascination① 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 knowingwhat the stars were,people in ancient times used their imaginations to create a world in the sky.[1]not knowing what the stars were為動(dòng)詞-ing形式短語(yǔ)的否定形式,在句中作狀語(yǔ);what引導(dǎo)賓語(yǔ)從句,并在從句中作表語(yǔ)。[2]Our power to investigate⑤ and thus understand space changed dramatically⑥ when the first telescope⑦ was 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 cosmic ocean.[2]本句句子主干為our power to investigate and thus understand space changed dramatically,主語(yǔ)中心詞為our power,動(dòng)詞不定式作后置定語(yǔ);when引導(dǎo)時(shí)間狀語(yǔ)從句;第二個(gè)and連接并列的結(jié)果狀語(yǔ)。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 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 conceivably 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 speed .[3]句中的兩個(gè)where引導(dǎo)的從句均為定語(yǔ)從句,分別修飾gas和planets。[4]句中that引導(dǎo)同位語(yǔ)從句。To see even further into the universe,many countries are now engaged in building ever more advanced telescopes .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 of subatomic particles invisible 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.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 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 for 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.眺望夜空的眼睛從人類(lèi)有史以來(lái),夜空就一直是讓人浮想聯(lián)翩的不竭源頭。例如在中國(guó)考古遺址三星堆發(fā)掘的古蜀國(guó)神秘的巨目銅像,古時(shí)的人們認(rèn)為它能夠看到遙遠(yuǎn)的星空。事實(shí)上,人類(lèi)僅憑肉眼只能看到夜空很小的一部分。并且在很長(zhǎng)一段時(shí)間里,人們都無(wú)法理解他們所看到的事物。古時(shí)的人們并不知道星星到底是什么,所以他們便憑著想象去創(chuàng)造了一個(gè)空中世界。當(dāng)?shù)谝慌_(tái)望遠(yuǎn)鏡對(duì)準(zhǔn)夜空時(shí),我們探索進(jìn)而理解太空的能力就發(fā)生了巨大變化,它不僅增強(qiáng)了人類(lèi)肉眼觀測(cè)的能力,而且也讓我們明白宇宙要比之前想象的大得多。每個(gè)行星都可以被視為和我們地球類(lèi)似的星球,其中許多行星甚至有它們自己的衛(wèi)星。很快,我們明白太陽(yáng)只不過(guò)是銀河系中數(shù)十億計(jì)的恒星中的一顆。大約300年后,我們又得知,銀河系只是數(shù)十億個(gè)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與物質(zhì)組成的大型島嶼。第一個(gè)地基望遠(yuǎn)鏡問(wèn)世將近400年之后,哈勃空間望遠(yuǎn)鏡發(fā)射入軌,不僅讓天文學(xué)家,事實(shí)上還讓我們所有人,都看見(jiàn)了來(lái)自地球之外令人嘆為觀止的宇宙美景。它讓我們史無(wú)前例地看到了如此遙遠(yuǎn)的景觀——從星體誕生的巨大氣體云團(tuán),到巨型黑洞,甚至到可能會(huì)發(fā)現(xiàn)生命跡象的新行星。不僅如此,它還幫助我們測(cè)算宇宙的年齡并分析宇宙的本質(zhì),且發(fā)現(xiàn)了驚人的事實(shí)——宇宙正在以不斷增加的速度擴(kuò)大。為了能更加深入地觀察宇宙,很多國(guó)家開(kāi)始投入研發(fā)更先進(jìn)的望遠(yuǎn)鏡。近來(lái),中國(guó)研發(fā)了世界最大、功能最強(qiáng)的射電望遠(yuǎn)鏡——FAST望遠(yuǎn)鏡,于2016年建成。眾所周知,這個(gè)被稱(chēng)為“天眼”的500米口徑巨盤(pán)用于探尋暗物質(zhì)。暗物質(zhì)被認(rèn)為由亞原子粒子組成,一般望遠(yuǎn)鏡是觀測(cè)不到的。這個(gè)巨盤(pán)還能探索數(shù)十億光年之外的太空領(lǐng)域,那里是看得到的宇宙的邊界。哈勃望遠(yuǎn)鏡以及在它之后建成的太空望遠(yuǎn)鏡將使我們能看見(jiàn)更加遙遠(yuǎn)的太空。我們將能觀察幾十億光年外的星體和星系,回看數(shù)十億年之前的過(guò)去。終將有一天,我們會(huì)使用更巨大的射電望遠(yuǎn)鏡當(dāng)作人類(lèi)之眼,回看在光產(chǎn)生之前的宇宙的最早時(shí)期。但人類(lèi)對(duì)知識(shí)的渴望不止于此。宇宙還有很多的未知領(lǐng)域,我們才剛剛接近這段奇幻發(fā)現(xiàn)之旅的起點(diǎn)。THANKS
