"革命是历史的火车头"
— Karl Marx
Simplified Meaning:
Big changes in history often happen quickly and dramatically, like a train speeding down the tracks. For example, think about the American Revolution. Before the revolution, the American colonies were ruled by Britain and had no say in their laws. Then, people got together and fought hard for their independence. After winning the war, they created a new, democratic country – the United States. Revolutions work like this because they push things forward fast. Instead of small, slow changes, revolutions bring about big shifts in power and society. They remove old ways of doing things and make room for new ideas and systems. So, if you want to understand why some periods in history are marked by swift, important changes, it's often because a revolution acted like the engine making these changes happen quickly and powerfully.
