There are many technological things around us, such as rice cookers, computers, televisions and electric lights. Our science is really getting better and better, which is created by everyone's efforts.

Science brings us many benefits and makes our life better! The efforts of scientists have not been in vain! The former yellow mud road → mud road → cement road → has evolved into today's asphalt road, which shows that our traffic has improved. The previous moonlight → fireflies → oil lamps → kerosene lamps → evolved into today's electric lights, indicating that our fire lamps have improved. Now there is something new. The details are as follows: Recently, we found that there would be a car running through the traffic lights on our road, so we installed a camera. Once the car runs a red light, it will be fined 200 yuan. That thing will film the scene! My uncle is an example because of the curiosity of my cousins. Now we can all cross the road safely! How convenient!

We have cars on the road, ships on the sea, planes and rockets in the sky ... we have got rid of the "two-legged vehicle", which is a scientific progress. Science will bring us a better life!
