The benefits of children's encyclopedias

1, I like reading children's encyclopedia very much.

Today, I am at home and have nothing to do. I took a children's encyclopedia. I opened the second page of the book and saw an article about how the camera was invented.

Written in the18th century, a French painter projected a figure on paper with a candle and outlined the figure with a pencil. This is the earliest photo shoot. 1802, an Englishman named Wichiude made a printing paper to take pictures of people. 1872, Frenchman Knibbs studied photography. 1839, Frenchman Daguerre was also keen on photography. Once, he happened to find that a metal plate coated with iodine could take pictures of objects. After repeated experiments, he knew that mercury evaporation could develop negative films, so he invented negative films and development technology. Later, a man named Huck Jill invented a fixing method. His invention combined with Vichud's printing paper to form a whole set of photographic techniques. Later, people improved it. The camera was born.

After reading this invention, I know that I should pay more attention to the things around me, and I know that through my unremitting efforts, I will certainly gain something. I also think that we are now in the learning stage, so we should study hard and master the skills. When I grow up, I want to invent something useful that people have never seen before, so it can bring convenience to people.

2, reading' Children's Encyclopedia' feelings

I like reading. There seem to be endless books on the bookshelf, desk and piano. Among these books, I like reading children's encyclopedias best.

This set of books includes more than ten categories such as earth knowledge, cosmic mystery, animal world and plant world. Among them, I like Animal World and Plant World best.

Marine life, land life, insects and beasts are common in the "animal world", but do you know the mystery? Why do whales commit mass suicide? Because of the pollution of the deep sea environment, whales swim to the shallow sea, and because of their overweight, their internal organs are squeezed and they "commit suicide".

The plants introduced in Plant World include flowers without fruit, fruits without flowers, fruits underground, fruits hanging on branches, those growing in the ocean, those growing on land, those growing in rivers and so on.

After reading this set of books, I really benefited a lot The phenomena in nature seem simple, but in fact they contain many complicated truths. We must observe and think more to get the correct answer and make our life more mysterious!

In this summer vacation, I read a book called Children's Encyclopedia. After reading this book, I know a lot about animals. Do you want to know? Then look carefully below!

Do you know why chickens like pebbles? That's because the chicken's stomach is very special and can bear stones. The stomach wall membrane of chicken is very hard, like an elastic plastic bag, which has strong digestive function. It has no sharp teeth in its mouth, so it is difficult to chew grains, rice grains, wheat grains and so on. So you need to eat some pebbles to grind food to help digestion and absorption.

Why do chickens like pebbles? How do swallows build nests? Bird's nest is usually built under the eaves where people live. When it builds a nest, it first stands on the wall, supports itself with feathers, piles broken mud on the wall, and then mixes broken tiles and grass stalks from other places into the mud, encloses it with mud, and puts hay and feathers inside, thus forming a comfortable nest.

After reading this "children's encyclopedia", I feel that my knowledge is endless and I can't finish learning. If we read more books, our brains will be full of strength.
