EYES UPON THE NIGHT 眺望夜空的眼睛
Para1:
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,
(过去分词短语作后置定语，修饰statues)
were believed to have been able to look across
great distances 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.
(Not knowing..., 现在分词短语作原因状语；
what引导的从句作knowing的宾语；
to create a world in the sky不定式短语作目的状语）
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。
Para2:
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 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 galaxy 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 matter floating in a vast cosmic ocean.
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亩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。
Para2:长难句分析
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.
1. to investigate and thus understand space
动词不定式短语作后置定语修饰power
2. when引导时间状语从句
3. and 连接两个并列的现在分词短语作状语
4. as it did the power of the human eye
是由as引导的方式状语从句，
其中助动词did代替实意动词 “increased” ;
5. that the universe is far larger than...; that 引导的是宾语从句
6. 比较连词than连接的比较状语从句，
省略了主语the universe,
其完全形式为 “the universe 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亩要比之前想象的大得多。
Para3:
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, 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 discover the incredible
fact that the universe is expanding at an
ever-increasing speed.
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一一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。
Para3:长难句分析
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.
1. where stars are being born,
where引导定语从句，修饰clouds of gas
2. where we mightconceivably find life.
where 引导定语从句，修饰new planets.
它让我们史无前例地看到了如此遥远的景观一一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。
Para4:
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.
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。
Para4: 长难句分析
The 500-meter 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.
[句式分析]
1. “as it is known” 意为“众所周知”;
2. “thought to be composed of subatomic particles invisible to ordinary telescopes.”为过去分词短语作后置定语，修饰dark matter
3. “invisible to ordinary telescope” 为形容词短语作后置定语修饰名词 subatomic particles.
[尝试翻译] 人们逐渐了解，直径天500米的圆盘望远镜被用于寻找暗物质，人们认为暗物质是由普通望远镜无法观测到的亚原子粒子组成。
Para5:
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.
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。
Para5: 长难句分析
So much of the universe remains unexplored that we are still close to the start of this incredible journey of discovery.
so…that 引导的结果状语从句
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。
Not only that—it has also helped us to work out the age and nature of the universe, and discover the incredible fact that universe is expanding at an ever increasing speed.
