A
I was part of a crew that was sent into outer space for a task. The task was carried out successfully and I was on my way back to Earth with my friends.
Suddenly, an unknown flying object appeared and it somehow forced our spaceship to land on another planet.
On the planet, a very strangelooking creature met us. This creature took my crew and me to see its master. I saw another alien (外星人) sitting on a very high throne. That must be their master. It wore a crown and looked like all the strangelooking creatures in the room but its head was much bigger. All the aliens had four eyes, two heads and six legs. They had a white body and no hair.
There was a very high wall all around the planet. It had many buildings and wherever you went, you could hear the crying sounds coming from small cells.
We were scared and they gave us some food, which smelt like rotten fish. The smell was so strong that we had to hold our breath in order not to faint (晕倒). No one dared to touch the food.
The next day, we were given a long list of things to do but they spoke a language that we could not understand at all. They whipped (鞭打) us and put us in a small cell. After that, they conducted experiments on us. A few of us died but the rest of us who survived were put back into the cell.
One day, the aliens—who brought us to our cells—forgot to lock the door so we escaped through the door. Soon we boarded our own spaceship and flew back to Earth. We had a horrifying experience but no one believed us! After this, I never dared to go into space ever again.
