Write My School Bag with the title of an expository essay at least a column of numbers for example:

A school bag is a bag made of cloth, leather, etc., which students use to carry textbooks, stationery, etc.

My schoolbag has been with me for two years of study, and my study utensils are placed there, it is like a good partner in my life, a little helper in learning. My mom bought it for me when I was in elementary school and junior high school.

My schoolbag is a Li-Ning.

The backpack is generally a vertical box type. It is about 25 cm wide, 45 cm long and 14 cm high. The maximum load capacity is about 10 to 15 kg. Polyester fabric is used.

With a stiffer feel, this material can make the bag more durable and have a higher load capacity.

The outside of the bag is generally black, with some gray in the middle. There are the abbreviations of Li Ning on the front of the school bag. Below the abbreviation is the oblique gray striped Li Ning trademark, which is also mixed with five colors: black, red, green, yellow and blue, symbolizing the five continents.

and the Olympic spirit of the Olympic Games.

On both sides of the bag are two mesh pockets for other items such as water bottles.

The inner part of the schoolbag has two layers, and there are two cables on the outside, which are hollowed out in the middle in the shape of willow leaves, and are engraved with the abbreviation of Li Ning. The larger floor has a mezzanine to distinguish the various types of books; The smaller level has a compartment for pens or other stationery. Most of the remaining space is used for books, which saves space and makes it easier to sort the two items.

The back of the schoolbag adopts a streamlined design, the middle is concave inward, and the top and bottom are more convex, so that the design can relieve the pressure caused by the heavy objects on the backpacker's back The two straps are located at the back of the bag, and there is an elastic fastening in the middle of the strap to facilitate the adjustment of the length of the strap. There is a one-hand pull strap on the top of the bag for easy lifting.

It's stylish, it's not clumsy, it's durable, it's my bag.

My bag has only two layers, and although it is not large, it is very useful.

The schoolbag is purple, and there is a cute bear hanging on the zipper next to it, which accompanies me to and from school every day, and sometimes I will whisper to it, and the relationship between the two of us is deep!

The front layer of the bag is a small compartment, which usually only contains small items such as tissues, gloves, keys, and wallets. Because it is very convenient to gather them in small compartments and take them out when you need them, and it is not easy to find them if you put them in the later layers, so small compartments are very useful.

The first layer behind the bag is a place where you can use textbooks, extracurricular books, triangular rulers, stationery boxes, and other things you need to use during class. In order to keep them lightly scented, I always spray less perfume in the back compartment, which is also very useful.

Schoolbags are indispensable things when we go to school, but some students don't take care of it, when it rains, the schoolbag becomes a "shield", and when playing around, the schoolbag becomes a "new-style" ......

My schoolbag is not outstanding among my classmates, because it is not as colorful as my classmates, it is just an ordinary lilac, but this is not outstanding beauty and beautiful, because it accompanies me to and from school, it is my good friend, and it is an indispensable thing in my life.

My bag is very versatile and I love it.

I have a grass green schoolbag, which has been used for 5 years, although it is worn, but I love it very much After listening to my father's words, I thought, in the old society, in order to survive, it was so difficult for my father to even learn abacus. As for me, I have superior learning conditions, the teacher's patient teaching, I can ask people at any time if I have questions, and compare with my father when I was a child. That night, I seemed to be energized and refreshed.

Lie down on the table and do the abacus problem you got wrong again and again from beginning to end. "Two one adds five, five two times makes four" memorized the mantra well, and understood everything he didn't understand before.

Another time, I was having fun when I suddenly received a geography quiz paper approved by the teacher. When I opened it, my heart was as heavy as a lead: I had scored 2 points.

How can you put such an ignominious score in your school bag? Dad used it to hold party documents! I'm so sorry for this bag.

But then I thought, 2 points have already been scored, and it is useless to be pessimistic and disappointed, I should study hard and catch up with my homework. When I got home, I stopped playing, and I opened my bag and studied geography. After many revisions, I memorized all the geography that the teacher had talked about.

Two weeks later, I took another geography quiz and I got a 4. At this time, I thought: I can't be satisfied, and I can't relax!

I should continue to study my homework, strive for 5 points, and never let bad grades fit into my schoolbag again!

I've been using this bag since I was in second grade. I protected it very well. Once, a copper button fell off in my school bag, and I hurriedly picked it up and ran home to nail it stitch by stitch.

When I was in the fifth grade, my father came home from work one night, opened my school bag to check my homework, and when he opened my abacus book, he saw that the words were written in a mess, the formula was wrong, and the answer was wrong, and he didn't even eat, so he put the abacus in front of me, told me to play again, to see if there was anything wrong, and asked me to read the mantra again. I read the mantra so-so, and my father was very upset when he heard it. When I was about to make a plate, my father saw that I always used my thumb to pluck the beads, so he patiently taught me, but I still only used my thumb to pluck ......Dad said that in the past, whether it was the scorching summer of the red sun or the cold winter of the ninth month, he stood every night to practice the planning board.

My feet are numb, and my hands are sore, but I still practice.
