1. Since ancient times, the evolution of human works is largely due to curiosity, the law of gravity, the law of buoyancy, the invention of electric lights and telephones, and all these earth-shattering feats are due to people's curiosity and their coming out one by one.

I remember that year, our classmate Dayong took us to a deep mountain. On the rugged mountain road, a group of fourth-grade pupils struggled forward. Everyone is in a bad mood except Dayong. Finally, this guy took us to a cave. We were shocked. A hole? A hole only 40 cm wide, Yong said, "Maybe there will be treasures left by pirates in this hole!" " Could it be a treasure map? "

We were all confused because his words were so false that we didn't help him. We looked at his hole and reached for a long time, but there was nothing. So, we broke up in discord.

I also have a classmate, Xiao Zhang, who loves invention and is curious about the world. However, his invention failed in the end, and he wanted to fly in the sky like a bird. However, the wings he invented caused him an accident and he was hospitalized for half a month. His family also blamed him for this for a long time. He also promised his family not to mess with the plane. After that, he never did anything drastic, but I found that he had been reading relevant reports.

I think it is not a good thing for people to keep too much curiosity! But a few years later, I found that my point of view was wrong ... This year, in my third and sixth grade, the school held the "I am an inventor" contest, and the solar plane model developed by Xiao Zhang made us shine. The biggest difference between this toy and ordinary toys is that its circuit board adopts solar energy technology, which can convert solar energy into electric energy and fly infinitely in the sun.

6. This invention won the first prize in the competition and won a prize of 50,000 yuan. The country is going to transplant this technology to the space shuttle.

7, curiosity, sometimes can not kill the cat.
