一天晚上，我睡觉前爸爸给我讲故事，他说：小明和爸爸去郊外， 他们看到一列火车飞驰而过。
One night, before I went to bed, my father told me a story. He said: Xiao Ming and his father went to the countryside, and they saw a train flying by.
小明查了好几本书，他对爸爸说：爸爸最早的汽车是蒸汽机车，后来发明了内燃机车，再后来有发明了电力火车、磁悬浮火车，爸爸说：你真棒!
Xiaoming checked several books, he said to his father: Dad's earliest car was a steam locomotive. Later he invented the diesel locomotive, and then he invented the electric train and maglev train. His father said: you are wonderful!
我也要向小明学习，有问题自己动手查找答案。
I also want to learn from Xiao Ming and find out the answers to the questions by myself.
