Why do you write 400 words after reading100000?

You can refer to the information on the Internet.

There is a lot of content in "100,000 Why". I talked about many aspects, such as communication, transportation, military, human body, plants, medicine, animals and so on. No wonder he is called "100,000 Why".

I like an article in it best. What is the Big Dipper? The Big Dipper is the seven stars in Ursa Major, shaped like a spoon. The two stars of Polaris on the spoon-shaped side of the Big Dipper are connected together and extend five times in the direction of the spoon mouth.

When I was a child, I also heard grandma tell the legend of the Big Dipper. After reading a hundred thousand why, I think there are many interesting things in nature. Or we didn't find it. Therefore, in life, we should be good at discovering and thinking seriously.
