Whenever I go to the teacher's office, I will see a hill of exercise books and papers piled up on the teacher's desk. I think: how tired it is for teachers to correct so many papers and so many homework! I really want to invent a magic pen to correct the homework for the teacher and make the teacher relaxed!

One day, when the weather was sunny and the gongs and drums were loud, I walked to the podium to show my invention: a magic pen with a green coat and two buttons on it, one red and the other green. Its nib is a scanner, and there is a micro calculator on its cap. When the teacher points the pen at the paper, he scans the paper through the tip of the pen to judge whether the questions on the surface of the paper are correct. If the question is right, the green light on the pen will light up, and when the question is wrong, the red light will light up and make a beep. The most amazing thing is that after the papers are corrected, the calculator on the pen cap will automatically calculate the score of each paper, so that the teacher can easily correct each paper.

"smile, the sun is shining, don't get up!" " Ha ha! It was a dream. I really want to grow up quickly. When I grow up, I want to make this kind of pen for teachers, so that teachers can easily correct their homework with the pen I invented! 2.

[Magic pens for writing] pens are indispensable things in our lives, including pencils, pens, crayons, ballpoint pens, brush pens and watercolor pens ... However, these pens are not very good, and they are magic pens for writing. For example, pencils have lead, and pens need to be sharpened; It is troublesome to add ink to the pen; Crayons are gone when they are used up, which is not good; Ballpoint pen, need to change the refill; Brush, hair will fall off, unreliable, add ink, trouble; Watercolor pen, what should I do if the color is finished? Now, when I am in the third grade, I need to write with a pen. However, I often encounter the phenomenon of paper cutting, unsatisfactory ink filling and ink leakage. For this reason, I want to make a new type of pen. This pen looks like an ordinary pen. When I type ink, as long as the nib touches the ink, it will automatically absorb the ink in a blink of an eye. If I drink the ink once, it can last for a week. When I hold it correctly. It's all recessed a little, which is convenient for holding the pen. If the posture of holding the pen is incorrect, the pen will sense it, and you won't be able to write any words. If you write something wrong, don't be afraid. Just gently press the pen hanging on the pen cap and wipe it with the head of the pen cap, and the typo will disappear without a trace, which is guaranteed to be like never written. Students, look! My pen is amazing enough! I hope this pen can help you. 4. If I had a magic pen to write 3 words < P > If I had a magic pen. I believe that everyone has had such an idea in their minds.

Before I know it, I have become a famous inventor and invented a magical pen. Let's have a look! Nowadays, there are many kinds of pens, such as pencils, pens, ballpoint pens, etc., which are too many, messy and annoying! So, the pen I designed said it was magical, and it was really magical because it had several characteristics.

This pen can be used as any pen, because it also has a voice control system. When you want to use what kind of pen, just gently call out the name of that pen, such as pen, and it will immediately appear a pen, which will ensure your satisfaction.

not only saves the space of the pencil case, but also is convenient to use, isn't it good? This is its first major feature. Nowadays, children, especially girls, like beautiful patterns on pens best.

lovely patterns, small hanging chains on pens, and some beautiful decorations. And I can't wait to be the same every day. How can parents be satisfied? However, this matter can't be difficult for me! The second characteristic of this pen I designed can be said to be specially prepared for girls! When you buy this pen back, you may be surprised to find that there is a very small pen, a large pile of thin plastic paper and many cloth balls in the package.

I guess you will be surprised, but you can either forget it afterwards or throw it away as waste paper. If you really do this, it's all wet! Because all you have to do is pick up that small pen, draw some patterns you like on plastic paper and cloth, then wrap the plastic paper on the pen and wait for three seconds, and the pen will be completely new and transformed into another pen.

what? Surprised? Ha ha! To tell you the truth, those plastic paper and cloth balls are magical! Ok, stop talking, or you won't finish talking for three days and three nights. Let's experience it slowly when you have this pen. 6. I am a magical person

With the continuous improvement of science and technology, the members of the pen family are increasing, such as feather pens, dip pens, pens, pencils and ballpoint pens ... Among them, the ballpoint pen is the most popular one. However, the ballpoint pen also has many shortcomings, such as error correction, color size and so on. I want to invent a magic ballpoint pen to correct these shortcomings.

The appearance of this kind of ballpoint pen is no different from that of ordinary ballpoint pen, but no one can compare with the structure inside. Pull off the cap of the pen, and there are three buttons in the pen, namely red, yellow and green. The buttons are very small and won't affect your writing. The first red button is specially used to deal with typos. When you write a wrong word, you can erase it by pressing the red button lightly, which is as convenient as erasing pencil words with an eraser. The second yellow button is to change the color of the pen and pen. As long as you write the color you want on the paper, the pen and pen will show this color immediately. The third green button is used to adjust the length of the ballpoint pen. As long as you write the length of the pen you want on paper, the ballpoint pen will become what you want immediately. It's easier to carry. There is also a blue button at the end of the ballpoint pen. As long as you press this button, the ballpoint pen will emit bright light and become a flashlight, which is your little assistant when you travel at night.

Next, I will introduce another function of this pen, which can help you prevent myopia. When you are writing with this pen, when you are too close to the desktop, the pen will make wonderful music to remind you that you should hold your head high when you are too close to the desktop. Also, this kind of pen can be used indefinitely, unlike a pen, which needs to be filled with ink constantly.

How about this kind of ballpoint pen? I believe that with the continuous progress of science and technology, children will definitely have this kind of magic ballpoint pen in the near future. 7. Composition Unit 6, Volume 2, Grade 3. A magical thing. How to write this composition
