Why are the square grids on the bookshelf used?

As I grow up, I no longer like sweet and delicious chocolates, nor interesting TV series. I only like my small bookcase, because the bookcase brings me endless fun.

My bookcase has a fat body wearing blue clothes. It is divided into two parts: a writing desk and a bookcase. Below is a writing desk with four layers of rectangular bookshelves, and a small square grid embedded in the second layer. There are many books on the bookshelf, as well as my favorite little things. On the first floor is a set of "One Hundred Thousand Whys" and "Hans Christian Andersen's Fairy Tales"; on the second floor is my photo album, and in the small square grid are paper rolls for my handicrafts and a folder for various exercise books. Small boxes; the third floor contains "Excellent Compositions for Primary School Students", "Xinhua Dictionary", "Idiom Dictionary", etc.; the fourth floor contains "Riddle Collection", "Jokes Collection", "Comic Books" and Barbie dolls, as well as There are table tennis rackets.

When I was worried, I took out the "Jokes" from the bookcase and read it. The jokes in the book immediately threw my worries away; when I encountered a word that I couldn't write, I read it. I took out a dictionary to look it up; when I was writing a composition, I took out "One Hundred Thousand Whys" or "Elementary School Student Composition" from the bookcase for reference; when I was bored, I took out the "Comic Book" and read it. I will also play with my Barbie dolls, or take out my paper roll and make a telescope or a pagoda. Soon my time will be very happy again. Every time I finish reading a book, I put it back in its place and arrange it neatly.

This bookcase is a good helper for my study and a good partner in life. It is not only a teacher full of knowledge, but also a close friend. I love my little bookcase!
