Describe a time you watched the sky.
You should say:
when this happened
who you were with
what you saw
and how you felt about watching the sky.
I remembered when I was a boy, ten years old maybe, my parents took me to the countryside to take a summer holiday. There, I was really into watching the sky especially at night to count the countless stars. I sometimes laid down in the grass for hours with dad to watch the shining stars because I was fond of imaging the folk stories about the stars.
As my hometown is a tourism city and there is no any industrial pollution, the sky is always clean and clear, and I could see the stunning night sky with countless and glittering stars and sometimes even the galaxy. But unfortunately now in a metropolis like Beijing light pollution makes the night sky invisible.
When I watched the borderless dark sky, I wished that I could one day take an airplane or an space ship to explore the universe, like the Japanese cartoon, Robotech. Maybe that was the reason why I was fond of reading science fiction novels when I was in middle school later.
