During the Spring Festival, I watch a sci-fi movie The Wandering Earth with my friends. The movie direct by Guo Fan is very popular in China. It is set in 2075, where the earth is no longer safe to live. Unlike most western movies, the heroes do not give up the earth. Instead, they choose to save the earth by send it to another so-like system. I was deep impressed by the three generation of a Chinese family. They devote them to the mission. The movie conveys lots of Chinese values, but I think it is quite worth seeing it.

8 . The story happened in ancient times. A king was so clever that he thought of a good way to test     1     his men were reliable.

One day, he had a huge rock     2     (place) on a roadway at night. Then he hid     3     (him) nearby and watched carefully to see if anyone would remove the big rock. Some     4     (wealth) businessmen and high officials came by, but they simply walked around it. Many of them even loudly blamed the king for not keeping the roads clear, but none of them would bother     5     (get) the big stone out of the way.

Then a villager came along carrying a load of vegetables. On     6     (approach) the big rock, he stopped and laid down his burden, trying hard to move the stone to the side of the road. After much pushing, he     7     (final) succeeded. As the villager picked up his load of vegetables, he noticed a purse lying in the road where the rock     8     (be). The purse contained many gold coins and a note from the king, saying that the gold was for the person     9     removed the huge rock from the road.

The villager learned a valuable lesson that many others would never understand: Every obstacle presents     10     opportunity to improve one’s condition.
