First, we came to the Traffic Safety Museum, where there are two machines that look like cars instead of cars. A child excites them, doesn't it It turned out to be a machine that taught you to drive. A child was anxious to try, but the clutch was too loose for the car to start. Another child came up, and the clutch finally passed, but when shifting gears, the car stopped again and did not step on the clutch. "Let me do it," a loud voice shouted. It turned out to be my brother who is a racing fan. He got on the machine, stepped on the clutch unhurriedly, and then released it gently and smoothly. The car slowly moved forward, only to see his right foot step on the accelerator and the car moved forward quickly. It was not until it was time to shift gears that he stepped on the clutch with his right foot, adjusted the gear lever to the first gear with his right hand, and then released it, and the car moved forward smoothly. He has driven along this track twice in a row, and finally stopped firmly by the side of the road. "Amazing" I couldn't help but praise, and other children on both sides also praised it. Another child is not convinced and wants to show off. Who knows that his car stepped on the accelerator before it started, which made us laugh and cry.
We also visited the Museum of Popular Science Knowledge, where a cone-shaped object rolled down a slope, loaded it and returned automatically. There are laser sound, wind power generation, hydropower generation, power generation, virtual gun launch, as well as three "bottomless pits" and magnetic balls. ...
Next, we walked into the National Defense Security Museum, and we were presented with glittering ammunition, including bullets, shells, grenades, old telephones and telegraph boxes. As soon as I looked back, I saw the heroic deeds of revolutionary martyrs. I think this beautiful life today was bought with the lives of those revolutionary martyrs, so we must cherish it!
