2. Introduce a product in 600 words. I will introduce several new types of glass, each of which has its own function.
First of all, I want to introduce a kind of glass called "ocean exploration glass". This kind of glass allows you to see the scenery in the ocean at home. There is a receiving device and a screen in the glass. You can receive the scene in the ocean through the receiving device and then play it on the screen. This kind of glass can be used by people at home because it can let you see more kinds of fish than the aquarium.
There is also a kind of glass, which is not used for seeing things, but also for listening to music. This kind of glass is called "music glass". There is a miniature "player" in it, as well as all kinds of songs, and there is a very special device that can detect what kind of songs you like to listen to and then release music from the player. When you can't sleep, it will play a relaxing lullaby to make you fall asleep quickly. When you are angry, it will play very lyrical music to calm people down and let your anger slowly disappear. "Contact glass" is also good. It can be invisible and used for theft prevention. This kind of glass can be used to make doors. It's hard, and ordinary attacks have no effect. Besides, glass is invisible. When the thief saw it, he thought there was no door, so he ran over and was hit. This glass has the function of shooting, and the thief's appearance is clearly photographed. When the owner comes home, he can contact the police, so that the thief is caught.
In modern cities, people can't breathe fresh air, but "air evolution glass" can help you breathe fresh air. There is an air evolution device in the glass, which sucks in air, filters out all the dust inside and then releases it, so that you can breathe fresh air.
Nowadays, glass has more and more functions, and more magical glasses will go to the world in the future.
Introduce a 600-word composition (2) Flying Hat
One afternoon, as soon as I got home from school, I shouted, "Help! Somebody please. Yes, yes, there are ghosts! " At that time, the home was very deserted, and my crying broke the lonely mirror. My feet trembled with fear. Do you know why? Because there is a hat on the ground, and this hat can actually move! I picked up the stick I found in front of my house and touched the hat on the ground. Unexpectedly, it hid as soon as I touched it. Boy! I plucked up my courage and provoked the hat on the ground: "Gee, white startled me, it turned out to be a turtle!" " "
This guy is cute, with a green and heavy house on his back, two thin and red patterns on his face, and his small eyes staring at me as if to say, "Hey, you monster, let me go!" " "This little turtle is so cute, but no matter how cute you are, you piss me off. See how I torture you. Do it. I mixed detergent with water, blew out many small bubbles with a thin straw and put them on his back. Very interesting. I saw this guy struggling desperately in the "swimming pool", his limbs kept waving and there were some small bubbles in his mouth. He looked at me imploringly with innocent eyes, as if begging for mercy there, which made me very uncomfortable. Forget it. I'm a gentleman. If I don't tell you the truth, I'll let you go. See if you have courage in the future!
In the future, this guy will live and work in my home. I have to wait on him every day. He is very picky about food. He likes eating meat, and he must clean his room regularly. Otherwise, he will protest to me and hide in the shell and not play with me! Sometimes I put it in my hat to scare my brothers and sisters!
This "moving hat", I really became your servant. Hey, but who made me like you?
Introduce a 600-word composition (3) Wonderful axle secret
Everything in the world is beautiful and must be pondered over and over again to understand. Science is like this, as long as you think hard, experiment and explore, you will understand. The other day in science class, the science teacher talked about the fourth lesson "The Secret of Axle". I read a science book. There is a faucet in the book. The book says, "Like a faucet, the machine that fixes the wheel and the shaft together is called a shaft." Yes, just turn the tap switch. It looks like a small wheel. Look at the small iron bars below. Put them together and they will come out as soon as you twist the water. Very convenient. If the wheel is removed, I imagine it is very laborious to smooth the iron bar, then the wheel and shaft will be really labor-saving. If it is laborious, why should people invent it? Everything is to save labor and facilitate people's lives. There is also a screwdriver in the book. It asks, "Is there anything in common between the screwdriver and the axle?" Honestly, I don't know. After returning home, I found a screwdriver, studied it carefully and finally found it. The shaft and the runner can rotate together with the shaft, thus opening the faucet and discharging water. Screwdriver also works by rotating. A screw is firmly embedded in the board. It is impossible to pull it out by human strength, make it rotate and take it out by hand. With a screwdriver, put it on the dent of the screw and turn it in one direction all the time. After a while, the screws will come out slowly. Therefore, the screwdriver and the wheel shaft have one thing in common, that is, they all rely on constant rotation to complete the task. In fact, the axle brings other conveniences to our life. Such as wheels and door handles. People used to use fans, but now with electric fans, the blades start to turn and drive the shaft, thus generating wind and people will be cool. I finally figured it out, so excited and happy. I hope to explore and study more things that are beneficial to mankind in the future.
3. Introduce the products of a hometown (composition) 400 stones in my hometown Looking at so many grotesque stones, we all have some fondle admiringly.
I begged my mother to buy a stone to take home, but even the cheapest cost several thousand yuan, so my mother had to take some photos of the stone with her camera. Mother said, "With these photos, we can enjoy them slowly."
..... In my hometown, strange stones can be seen everywhere along the road and in front of shops. In order to see more beautiful stones, my mother decided to take me to see the stone hall in Lingbi.
Let's first walk into a stone hall called "Kistler Pavilion". As soon as I entered the door, I saw a big stone with many patterns on it, which looked like a bird.
I think it's strange. I think: Is the pattern on its body artificially carved or natural? My uncle in the Stone Museum seems to see my doubts. He told me: "This stone is called bluestone, and the patterns on it are all natural. If you knock it with your hand, it can still make a wonderful sound. "
This kind of stone is only available in Lingbi! "I also saw a stone like Maitreya, with a big belly and a string of beads hanging around his neck. We walked into another stone hall called Jinshizhai.
Wow! I gave a cry. Mom said, "What's the matter? Shout! " I said, "I saw a crystal stone."
My mother came over at once and couldn't help admiring: "How beautiful!" The young lady standing by said, "I want to eat rice." It turns out that my little sister ate it as a meal.
Crystal stone is crystal clear, much like petals, and each petal is really like a grain of rice. Then we walked into the "Wu Guan".
Here, I see a stone that looks like a frog. Its shape is hand-carved, and its eyes and patterns are naturally formed. It really looks like a big frog lying there! Looking at so many strange stones, we are all a little fondle admiringly. I begged my mother to buy a stone to take home, but even the cheapest cost several thousand yuan, so my mother had to take some photos of the stone with her camera.
Mother said, "With these photos, we can enjoy them slowly." On the way back, I was still very excited, but my mother was silent.
I asked my mother if she was sick, and she shook her head. My mother told me with a heavy heart: "There are fewer and fewer Lingbi stones. Many people dig stones without restraint for money. Maybe in a few years, we won't even see the mountains in our hometown, let alone the strange stones.
If you continue to destroy the environment like this, you will be punished one day. "Listen to my mother, I also lost in thought.
Yes, I love my hometown, and I love the stones in my hometown, but I hope people in my hometown can develop them rationally, and don't forget to protect our limited earth resources while beautifying our lives.
I stood on the podium, very excited, just standing there, smirking, as if I were the smartest person in the world. I am so proud that countless flashlights are shooting at me!
Recently, the examination stage has come and there are more homework. I lay in my cot, daydreaming outside the window. I see the stars in the sky are dense, busy and silent, but it seems that I only feel the excitement in the sky. A comb like the moon describes a young girl, but people are not shy, and the light and outline are fresh and carved, which can gradually set off the night scene. The path is quieter and the moon is brighter. The night wind is still blowing quietly, the swaying shadows are still shaking, and the fields exude a fragrance. The round moon climbed the treetops, the bright moonlight shone on the leaves, the birds slept in the warm nest, and slowly, I fell asleep. In the dream world, we can roam freely. My dream is to be a "scientist" who can invent many strange things for people. Now my dream has come true.
I am a great scientist, and I have invented an all-round environmental protection car that can change its shape at will. In the water, it is as flexible as a fish and can swim freely in the water. Put away four tires, and it becomes a submarine, which allows you to go anywhere in the water. We don't have to go to the aquarium to see fish anymore. You can see it at any time On land, it travels as fast as light. When you want to go to any corner of the city, just press the button and you will be delivered in the blink of an eye. You don't have to waste time on the bus anymore! In the air, there is nothing to talk about. It is more convenient than an airplane, and the spread wings can make a car fly more stably in the air than an airplane. I will never be affected by the weather again. I can fly whenever I want. That's cool! My invention won the Nobel Prize.
When I stood on the podium, I was so excited that I just stood there giggling as if I were the smartest person in the world.
"Jingle bells-Jingle bells-"My little alarm clock pulled me back from my beautiful dream. I stared at the alarm clock as if he were saying to me, "Get up, lazy boy. You should go to school. If you want to realize your dream, you must go to school first! " I will definitely work hard towards my dream and become a scientist who can serve the broad masses of people in the future.
In the dream world, I am not far from my dream, and so is my real life. As long as I work hard now, I can turn that short distance into zero distance in the future.

6. Write a composition recommending a product, 40o words. Hello, everyone, I am a' universal doctor' who can provide information for those good scholars; It is also a' bad guy' who can make those primary and secondary school students go astray and live in an empty network all day; I am everyone's favorite computer.

I, the younger brother of TV, have a square head and only one hand, which is equivalent to the "heavy" body of the brain. I have many brothers and sisters, such as Zheng Fang Computer, Lenovo Brand, Tsinghua Tongfang ... I can do many things. A small CPU in my body can check all the new things in the world. The internet is like a spider web all over the world. You can appreciate the length of the Great Wall by looking up information on the Internet. You don't have to go to Jiuzhaigou to appreciate its beauty. You don't have to go to Qinglong waterfall to know the ferocity of the waterfall ... but I use it occasionally. As long as the person who works for me is a hacker, he will "kill someone with a knife" and steal confidential documents from other companies. I have many uses: if you miss the movie that my' brother' lost on TV, you can use me; I can also let you play online games for a while, but don't be too excited to carve moxibustion and smoked abalone to wipe your fans, which will delay your study and don't even think about upgrading all day.
