In study, work, and life, everyone is familiar with composition. Composition is a narrative method that expresses the meaning of a theme through words.

So have you ever understood composition?

The following is my smart schoolbag composition that I compiled for everyone. You are welcome to share it.

My Smart Schoolbag Essay 1 In 20xx, I became an excellent designer and designed a smart schoolbag.

It is similar to an ordinary schoolbag. The difference is that it has a row of colorful buttons, including red, orange, yellow, green, cyan, blue, purple, and two LCD screens. The key is that these buttons have different functions.

?Press the red button and it will turn into a small bookshelf that can give you the books you need.

Pressing the orange button can help you study. If you encounter a question you don't know, you can scan it in front of an LCD screen to get the ideas and answers you want.

What is the other LCD screen for?

It turns out that it can send information about your absenteeism in class or cheating in exams to your parents’ mobile phones, so you can be scolded when you get home!

Press the yellow button, which has an anti-theft function. If you leave your schoolbag and someone comes to rummage through your schoolbag, an alarm will sound. If someone continues to rummage, an electric current will be emitted to knock him down.

If you are going to be late, just press the green button and he will fly you to your designated place to avoid being late.

If it rains, press the cyan button and an umbrella will appear, so you can go to school or go home safely.

By pressing the blue button, you can change it to the size, color and style you like, and you can keep it for several years without changing the bag.

When you are tired of reading, press the purple button. It can help you do eye exercises and relax you.

?Do you like this smart schoolbag?

If you want it, hurry up and order it!

My Smart Schoolbag Essay 2 Everyone has their own whims and whims, of course I am no exception!

My fantastic idea is to invent a smart school bag.

Because students’ schoolbags are too heavy!

The pressure made us hunched over and bent over.

The smart schoolbag is composed of blue and green.

The schoolbag is also decorated with clouds and rainbows, which is very beautiful.

Next, let’s take a look at the functions of smart schoolbags!

There are four buttons on the schoolbag strap, namely red button, yellow button, blue button and green button.

The red button can predict weather conditions in advance.

If it rains, I press the red button, and a cute pink umbrella will slowly come out of my bag to protect me from the wind and rain.

This way the clothes won't get wet.

The yellow button is like a treasure chest of snacks.

As long as I'm hungry, the smart schoolbag will produce all kinds of snacks I want to eat, which makes people very satisfied just thinking about it.

The blue button is the music button.

Whenever I'm in a bad mood and want to listen to music.

It will automatically play the songs you want to listen to, making you feel a hundred times more comfortable and instantly refreshed.

The green button is the flight button.

If you are too tired from walking, just press the green button and the bag will turn into an aircraft.

Take you wherever you want to go.

My whimsical idea-isn’t a smart schoolbag interesting?

My Smart Schoolbag Essay 3 I saw that my schoolbag was getting bigger and heavier, and it was like a big stone weighing me down.

How I want my schoolbag to reduce stress!

Finally one day, my dream came true.

I have a magical smart school bag.

The appearance of this smart schoolbag is no different from that of an ordinary schoolbag, but it is equipped with zoom-in and zoom-out keys.

When I carry my schoolbag to school and I can't carry it anymore on the way, I just press the shrink button and it will immediately make the schoolbag smaller and lighter.

When I got to school, I pressed the zoom button and the schoolbag immediately returned to its original shape.

If I don’t want to shrink my schoolbag, but my shoulder hurts, I just need to lightly activate another massage button on the smart schoolbag, and I will immediately feel the gentle vibration similar to a two-hand massage.

There is another feature that is most reassuring for parents.

This function is called a sensor. If there is a car in front of me but I haven't noticed it yet, it will sound an alarm based on the distance. This allows me to avoid danger and makes our family happy.

What attracts me most is the reminder button.

As long as I'm next to my schoolbag, it can remind me to do things on time: when it's time to go home, when it's time to do homework, when it's time to wash my schoolbag... It has never been left behind once. It is really a veritable reminder.

"Housekeeper"!

... "Dududu, get up! Dududu, get up!" I rubbed my hazy eyes, ah?

It turned out to be a dream!

My Smart Schoolbag Essay 4 In the past, in the summer, every time school was over, students would walk home carrying their schoolbags.

At that time, the schoolbag was unlucky. It became wet and smelled of sweat.

Moreover, the schoolbags were stuffy, the students were sweating profusely, and they were extremely hot.

In winter, the schoolbag is as cold as ice.

Now, I have invented a smart school bag that can solve all problems.
