Eyes upon the night
眺望夜空的眼睛
Do you know any of the astronomers in ancient China
Can you name some of their names and their contributions to the world
Lead-in
In ancient China, things like "EYES UPON THE NIGHT" are too numerous to mention. Here are some of the well-known figures who contributed to the exploration of the cosmos:①Zhang Heng (78-139 AD): An astronomer and inventor of the Eastern Han Dynasty, he created the world's first seismoscope and an armillary sphere to observe celestial movements.②Zu Chongzhi (429-500 AD): A mathematician and astronomer of the Southern and Northern Dynasties, he calculated pi with remarkable precision and improved the Chinese calendar, contributing significantly to the study of celestial mechanics.③Guo Shoujing (1231-1316 AD): An astronomer and hydraulic engineer of the Yuan Dynasty, he designed various astronomical instruments, such as the simplified armilla and the gnomon, and compiled the “Shoushi Calendar”, which greatly enhanced the accuracy of astronomical observations.④Yi Xing (683-727 AD): A Tang Dynasty astronomer and Buddhist monk, he led large-scale astronomical observations and compiled the “Dayan Calendar”, which had a profound influence on later generations.
These astronomers not only advanced the field of astronomy in ancient China but also left an enduring legacy in the history of global astronomy.
在中国古代，像“眺望夜空眼睛”的为探索太空做出重要贡献天文学家枚不胜举。以下举一些著名的人物事例：
① 张衡（78-139年）：东汉时期的天文学家和发明家，他发明了世界上最早的地动仪和浑天仪，用于观测天体运动和地震。
② 祖冲之（429-500年）：南北朝时期的数学家和天文学家，他精确计算了圆周率，并改进了历法，对天体运动有深入研究。
③ 郭守敬（1231-1316年）：元代天文学家和水利专家，他设计了多种天文仪器，如简仪和仰仪，并编制了《授时历》，极大地提高了天文观测的精度。
④ 僧一行（683-727年）：唐代天文学家和佛学家，他主持了大规模的天文观测活动，编制了《大衍历》，对后世影响深远。
这些天文学家的贡献不仅推动了中国古代天文学的发展，也为世界天文学史留下了宝贵的遗产。

The power of the human eyes changed dramatically
Later people knew 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.

Why do you think people have always been interested in the stars
People have always been interested in the stars because the night sky has been an endless source of fascination since the start of human history. Ancient people used their imaginations to create a world in the sky, and the stars have always been a mystery that humans wanted to understand.

2. Which development in astronomy mentioned in the passage has made the greatest impression on you
The development in astronomy that made the greatest impression on me is the launch of the Hubble Space Telescope. It provided breathtakingly beautiful images of the universe and helped us understand the age and nature of the universe, including the fact that it is expanding at an ever-increasing speed.
Think & Share
3. In what different ways do the two reading passages in this unit reflect this spirit of exploration
The two reading passages reflect the spirit of exploration in different ways.
The first passage is about the Challenger disaster. Although it was a tragedy, people did 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 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 of gaining knowledge.
Think & Share
4. Have you ever used a telescope or been to a planetarium Share your experience with the class.
I have used a telescope to observe the moon and some planets. It was an amazing experience to see the details of the moon's surface and the rings of Saturn. I also visited a planetarium where I learned about different constellations and the scale of the universe. It was both educational
and inspiring.
Think & Share
What do you think eyes in the passage refer to
“Eyes” in the passage refer to not only the mysterious large-eyed bronze statue of the ancient Shu Kingdom in China, the Hubble Space Telescope and the 500-metre dish of the “Eye of Heaven” built in Guizhou of China, but also stand for the spirit of space exploration.

Supporting examples: I can not agree with the saying more.
Take reading for example. The more you read good books, the more shallow you will feel, and the less when you realize that you know too little, you will actively do more reading. On the contrary, those who have read fewer books often think that they know a lot, but they do not realize that the ocean of knowledge is endless. As the saying goes, “My life is limited while knowledge is infinite.”

Dear Stephen,
I’m writing to seek your help.There exists a problem between my parents and me,making it impossible for me to concentrate on my study.I’m at a loss how to deal with it.
So crazy am I about space exploration that in my spare time I often go to the library to read something about space exploration.I think healthy hobbies are beneficial to our overall development.But my parents don’t understand me,which upsets me.They think my hobby will have a bad effect on my study sooner or later.As a consequence,
they do what they can do to prevent me from going to the library.To them,good marks mean everything and I should spend more time on my lessons.
I’d appreciate it if you could offer me some valuable suggestions.
Looking forward to your early reply.
Yours,
Li Hua
