In real life or work and study, many people have written compositions. Writing compositions is an important means to cultivate people's observation, association, imagination, thinking and memory. What kind of composition can be called an excellent composition? The following is the future fourth-grade composition I collected for you. Welcome to share it. The future pen composition 1

Although the pen we use now is very beautiful, it also annoys us sometimes. Because once the pen falls to the ground, the tip of the pen bends, and the hands are usually dirty when filling ink, and the model of the pen cannot be changed, so you can't always buy a good pen. So I want to invent a multifunctional pen.

There is a pen with a diameter less than in the top end of this multifunctional pen. 5 mm microchip, so the model, style and color of the pen can be controlled by voice, which is very novel.

The original shape of the multifunctional pen is a little dolphin, and its shell is made of a changeable super hard crystal, so it won't break when it falls. There are many pigment cells in the second layer, which can change color. The nib is made of a diamond that can change size and color. At the top of the pen, there is a blinking little star, which is very cute.

Another very important feature of this pen is that it can process water into ink. A little above the nib, there is an ink maker and an ink reservoir. As long as you put a little water, you can make ink. Then the reservoir will store three-thirds of the ink, and the rest will be left in the nib.

There are so many new functions: when I write a typo, the little star at the end will "shock" me; When I have words that I can't write, just press "Little Snowflake" and the words will be displayed in the little stars; When I have a question that I can't answer, I can display it in the little star by pressing "Red Apple". The air conditioner in the belly of the pen can also keep your hands warm in winter and cool in summer ...

This is a cheap pen, only ten yuan! Come and buy it. In the future, the era of writing 2

in the fourth grade is developing, science is progressing, and the pens in our hands are constantly upgrading.

now, it is 2xx years. I have been an inventor and invented a multifunctional pen. Now most students use this pen, which is only available in our company. This pen has multiple buttons.

When someone else takes this pen away, you don't have to worry. No matter how others press it, the pen won't listen to him, because this pen has a special function, which is fingerprint confirmation. If someone else's fingerprint is different from yours, the pen won't listen to him. This is the function of the first button. When you want to draw, pick up this pen and press the second button. This button is assigned by sound, and it can be any color you want to use. Magic! This is the function of the second button. When you write a typo, the third button will ring, and there will be a special alarm to remind you that there is a typo, so that you can correct it in time.

The pen body is made of advanced materials, and the pen tip is fixed by a special material. When your pen falls to the ground, it will not leak oil.

When you write homework with questions that you can't do, if you copy the homework, the homework will disappear. As long as you can't do any questions, it will be told to you until you understand it. A monitor is installed on the pen so that you can't cheat.

Is the pen I designed very applicable? I invented this brand-new future pen to benefit mankind! The future pen composition 3

In the future, there will be a magic pen.

The pen of the future is made of an ultra-thin rare metal. You've just started reading it, and you may be surprised, because it's full of water. But the color of the words you write is black! Why is this? Haha, you don't understand this. A converter is installed on the nib, which can convert tap water into ink. If you write a typo, don't worry, just press the red button on the pen, then you turn the pen upside down and aim at the typo, and the typo will be absorbed by the absorber inside without a trace and become tap water again!

If you encounter a problem while doing your homework, just press the yellow button and the answer will appear. By the way, there is also a color-changing device installed in the pen. As long as you press the green button, it will change color according to your requirements.

It's late at night. If you haven't finished your homework, and you're afraid to wake up your family by turning on the light, just press the blue button on the pen, and it will light up for you. If you are sleepy, just press the blue button and the pen will make wonderful music to help you out.

I believe that as long as I study hard, I will definitely invent this magical pen. Future Pens Composition 4

There are not only pencils and pens in my pencil case, but also fountain pens, ballpoint pens and magic pens ... which makes my pencil case full and heavy. With the rapid development of human science, I hope to invent a new comprehensive pen in the near future.

This pen is lovely in appearance and easy to operate. Except for one display screen, all the others are voice intelligent control. A pen can integrate all the functions: error correction, identification, troubleshooting, audio and video recording and so on. For example, I love to be careless, and I always lack pens and paintings when writing. With this pen, when I do my homework, it will prompt me by voice at any time and the correct answer will appear on the display screen. Or when I accidentally slip the number in class, the smart pen will not only remind me to pay attention to the lecture, but also record all the contents of the class for my review after class. This kind of pen can also switch the pen tip at any time, not only can it become a pen, pencil, fountain pen at any time, but also can become a colorful pen. This kind of pen is also very durable, without irrigation, and uses high technology to automatically generate the required ink.

this is the pen I hope will appear in the future. With the rapid development of science and technology, this kind of pen will definitely appear in our real life. Let's wait and see! In the year of 2xx, the scientific and technological level of human beings has been continuously improved, and a new type of pen has come out.

Because it is high-tech, this pen can change color and pattern. Just give the order and wait for three seconds, and it will be a brand-new pen.

Nowadays, students need too many kinds of stationery, so this kind of pen divides all pens into two categories, namely writing and drawing. Just say the pen you want and it will automatically stretch out. Therefore, it is enough for primary school students to take it with them when they go out to school.

Pupils have to bring dictionaries, dictionaries, idioms dictionaries and English-Chinese dictionaries to school every day, and their schoolbags are getting heavier and heavier. If you bring this multifunctional pen, it will be much easier. This pen has the function of looking up words. Say the type of words you want to look up, then say the words you want to look up. Point the small screen at the table like a projector, and you can clearly see the words, meanings and meanings that this word can combine.

Even if you occasionally lie there doing homework and writing, hunchback may occur, but the multifunctional pen solves this problem. Like a pen with a positive posture, there is an eyeball. As long as the eyeball sees that the student is sitting incorrectly, it will make a sound and recycle the nib. Some students wrap their eyeballs before writing, but once the eyeballs of multifunctional pens are invisible, they will recycle the nib, making it impossible for him to write.

this is a 2xx multifunctional pen. In the pen world, there are pens, pencils, ballpoint pens, writing brushes, crayons and so on. Among all kinds of pens, the ballpoint pen is the one I want to improve most.

Since my art class, my pen is always broken, and I borrowed it from my classmates many times, so I have a plan to improve my ballpoint pen.

In the future, I will definitely create a multifunctional pen! When I write with it, this one has an automatic speed-up switch. When I turn it on, I can write freely. When I write a composition with it, it can patiently guide me so that I won't be ill. With this pen, you don't have to worry about encountering words that you can't write, because this pen has the function of automatic prompt, like a gentle teacher teaching you how to remember how to write this new word; It is equipped with a typo discriminator. When you write a typo, it will make a beep to remind you.

There are also several induction lamp in it. When your head is away from the book normally, he will send out a blue light to tell you: the writing posture is right; If your head is too close to the book, it will give off a dazzling light, so that you can't read the words clearly. It, like a miniature air conditioner, will make you warm in winter and cool in summer. In winter, if you press the red button, it will emit heat to make you very warm. In summer, if you press the green button, it will make you feel very cool, like drinking a glass of manna, which is very comfortable!

The pen of the future is a magic pen, which can help us to write good words, draw good pictures, write touching articles, arouse our will, transform mountains and rivers and build a beautiful home. There is a good saying in the future fourth grade composition 7

: "Today's dream is the future reality." The present pen can do nothing but write, but the future pen can meet all your requirements, so that you have no worries. Now let me introduce you to

the future pen.

The future pen looks no different from ordinary pens, but its internal structure is more complicated, and it has many functions. What if the pen runs out of ink when you write? Don't worry, there are two small holes in the pen. One hole absorbs carbon dioxide in the air, converts carbon dioxide into ink, and converts excess carbon dioxide into oxygen to be discharged from the second hole. The longer you use this pen, the better your spirit will be.

do you feel very bored sometimes? You can listen to NP3 by pressing a small blue button on the pen, and watch NP4 by pressing a small red button. If you press a small green button, a big piano will appear, so that you can play the piano at any time.

I will study hard now, and I will definitely invent this pen in the future. The future pen fourth grade composition 8

We go to school with a big schoolbag on our backs every day. There are heavy stationery in the schoolbag and many pens in it. If the pencil case is lost, the pens in it must be gone, what a pity!

People in the future will invent a multifunctional pen, which can be converted into the pen we want to use according to our needs. In other words, we don't need to bring a pencil case, we just need to bring a pen when we go to school. When you want to write with a pen, you press the yellow button on the pen, and the pen will immediately become the pen you want; If this is an art class, don't worry, just press the pink button, and this pen will immediately become a watercolor pen of all colors you need; If you use a pencil, just press the green button gently. Haha, it's as simple as that.

this pen also has a special function, that is, it has the function of reminding people of mistakes. Every time we make a mistake in our homework, it will automatically send out a red alarm to remind us that we have done something wrong, and the red alarm will be automatically lifted until we write this question correctly. If you are lucky enough to muddle through, this pen will directly turn your homework into a blank. With this pen, mother no longer has to worry about our study.

The future pencil is very magical, and its refill will never be worn, broken and thickened. Because it has a magical refill-nano-refill. This kind of refill has a special function, that is, its "head" eraser. As long as you write a typo, it will emit red light and beautiful music, so that you can correct it in time.

When you take an exam, if your pen is out of water, just press the button on the right and it will give you inexhaustible ink. When you make a typo, just press the button on the right. There will be an eraser on its "head" that can check the pen.

The future red pen is used to correct students' homework. When you take out the test paper to be corrected and press the middle button, it can't wait to help you correct it. You just need to watch it correct it. When you correct the test paper, this question is wrong but feels right, or this question is right but you correct it, it will send out a voice: "Wrong, wrong, please correct it."

ballpoint pen, its effect is very, very good. If you run out of ink when writing and the teacher won't let you change the refill, just press the yellow button and it will automatically change the refill. When you don't understand, just press the green button and it will mark you with Pinyin.

ah! How magical and interesting the pen of the future is. Future Pencil 1

One day, I dreamed of a future pencil. Although the pencil looks the same as the present pencil, it has many functions.

that day, when I was doing my homework at school, I accidentally came across a button, and the pencil suddenly turned into a pen. I thought it was very novel, so I pressed another button, and the pen turned into a ballpoint pen, a writing brush and a colored pen ... The most interesting thing was the colored pen. I drew the frame in black, and when I finished the frame, I began to worry: I didn't know how to change the color. Suddenly the crayons said, "Young master, all you have to do is hold down the button and say the color you want, and I will become the color you want." I was very surprised, but I tried it, and it turned into the face bag I wanted. After a few days, I said, "I don't know how many days I can use it." The crayons said, "It doesn't matter, I can never use up this water." "Why?" I asked, "I will have ink wherever there is light." The colored pen said.

This pencil can not only become other pens, but also correct sitting posture! There is a liquid crystal screen on the pencil. When you sit incorrectly, the liquid crystal screen will flash red and make the pen unable to write, and it will not recover until you sit correctly.

"get up!" A voice woke me up. How I wish scientists could develop this pen as soon as possible. The future pen fourth grade composition 11

pens are indispensable stationery in our lives, but sometimes they are lost; Sometimes, a ballpoint pen will be crossed out if it is misspelled, and the roll surface is a little untidy. So, I want to invent a magic ballpoint pen.

This kind of ballpoint pen is particularly handy. There is a pen light on the tip of the pen, which will show the colors of red, blue and green. What should I do if I accidentally lose it? In fact, you don't have to worry, the pen light on the pen will show red, and it will keep flying, flying and flying to the owner's home; When I get home, the red color turns to blue, which makes it fly faster. At the door of the house, the blue color turns green, and a loud voice is made to tell the owner to open the door. When the host opened the door, the pen fell to the ground and let the host pick it up.

This ballpoint pen can not only go home by itself, but also correct the wrong words! When taking a test, taking notes or writing a composition, if a word is written incorrectly, tap the ballpoint pen gently and the nib will retract immediately. Then aim at the typo a little and it will disappear. Tap it again, and the nib will come out, so you can continue to write.

The pen is our faithful partner, and it accompanies us to study every day and night. I think: in the near future, this pen will be warmly welcomed by people and become
