Everyone knows that cars are people's special means of transportation. With the improvement of people's living standards, there will be more and more cars, but it will also bring people a heavier burden, such as traffic jams, traffic accidents, carbon dioxide emissions will pollute the environment and so on.

I want to invent a different kind of car. This kind of car is particularly advanced in technology. The driver is a supercomputer. It controls all the program systems in the car and can navigate automatically. It can not only travel on land, but also fly in the sky, fly like an airplane, go into the sea like a submarine, sail freely in the sea and automatically detect uninhabited islands. This kind of car is called a new car, which has three functions: sea, land and air.

Its energy is carbon dioxide, which releases oxygen and makes the air very fresh. If you are in the car and see the harmony between nature and the bustling high-tech city outside the window, you will be intoxicated and enter the dream world.

How's it going? Is the new car I invented not bad? I think this initial hope will come true one day.

At present, it is inconvenient for pens to absorb ink for a long time. Sometimes, just after absorbing ink, a big drop will suddenly appear and make the book dirty. Therefore, I want to invent a new multifunctional pen.

This pen is very special. The pen holder of this pen is made of carbon alloy, which is durable and unscathed when it falls to the ground or even steps on it several times. There is a micro robot in the nib to control the flow of ink. In this way, the ink will not flow out too much or too little, maintain a uniform flow, and write words with even strokes. You can also enter your favorite music. When the pen is out of ink, the robot in the nib will send a signal to remind you to fill it with ink. If your house is out of ink, the hole at the top of the pen container will open automatically. As long as you put some tap water, it will become ink within one minute, so it can be used for one or two months at a time.

This pen also has many wonderful settings: yellow button, green button and blue button, each with its own function. The yellow button has the greatest effect! You are writing with this pen. Because you are not careful, you wrote the word "old horse is hard to catch" as the word "four" for four people. It will beep and light up a red light on the wrong word to remind you that it is wrong! The green button plays a big role! When you have a word you don't know, when you are thinking hard, the shape and pronunciation of the word will be displayed on the pen cover to let you know the word. The blue button is big, too! If you have just finished your homework and the pen cover is not covered properly, the pen will beep when you are about to leave, reminding you to cover the pen before playing.

I will work hard for it and invent this pen as soon as possible! I hope I can bring more convenience to teachers and classmates, and I hope my wish can be realized as soon as possible.

I want to be a scientist when I grow up. I want to invent something called a measuring instrument, which can predict in advance how many earthquakes, tsunamis and storms will occur in that place. It mainly measures the exact location and time of earthquakes and storms. Let people no longer be buried in the ruins by earthquakes, and let people in houses no longer be attacked by big storms; Let people not die in vain.

My measuring instrument must be a hundred times stronger than the seismograph invented by Zhang Heng, a scientist in the Eastern Jin Dynasty. It can "talk" When there are earthquakes and strong winds, it will "tell" all of us two days before the tsunami: how many earthquakes, storms and tsunamis will occur there. Tell people to find a safe place to hide quickly. The accuracy of this measuring instrument I invented reaches 100%.

After I invented it, I want people all over the world not to be afraid of tsunamis, big storms and earthquakes. At that time, my mother, father and all those who love me will definitely praise me for being great.

Hey! Don't think about it, or study hard to realize my wish!
