2. The practical function of the cup combination multifunctional water cup
In the 22nd century, almost every household has a magic cup. No matter adults or children, they are full of praise and can't put it down! There are six beautiful and lovely buttons on this magical water cup. The first button is red with a straw painted on it. Just press this button and the straw will "rush" out of the cup like a naughty child. As soon as you finish drinking, the straw will automatically retract into the cup, and it will be sterilized and used next time. The second button is Huang Chengcheng's and it says: Hot, Warm, Cold. Three words. As the name implies, pressing the "hot" button will turn into hot water, pressing the "warm" button will turn into warm water and pressing the "cold" button will turn into cold water.
The third button is gold with drinks and juice painted on it. If you press the button and silently think of your favorite drink or juice, there will be the drink or juice you need in the cup. The fourth button is green with a rag painted on it. When the cup is dirty, the rag will stick out and wipe it spotless. The fifth button is purple, and many cartoon characters are drawn on it. As long as you press the button and say your favorite cartoon character, the cup will look like this cartoon character. Look! The little boy said, "Mickey Mouse!" The cup turned into Mickey Mouse at once. Look! The little girl said, "beautiful sheep!" " "The cup immediately turned into a beautiful and lovely beautiful sheep. The last button is colored and the most magical. It will automatically detect the water in your body. If you are short of water, it will automatically come to remind you to drink water. If you don't drink it, there will be a shortage of water on this button and you will be coaxed to finish this cup. Do you think this cup is amazing?
3. Write a paper about straw transportation.
It's a beautiful day today. Looking for the cool breeze in the morning and bathing in the sunshine all the way, I arrived at the Golden Pen School. As soon as I entered the classroom, I saw what my classmates were discussing. It turned out that I was guessing what game I would play in today's activity class!
"Jingle bells" was accompanied by a crisp class. Teacher Liu came into the classroom with a book and a mysterious smile on her face, and let the students guess for a long time before the teacher announced that he would play the game of "straw transportation" today. While the students were still wondering, the teacher explained the rules of the game in detail: in the process of transportation, hands should not touch the key ring, and the ring should not be dropped, otherwise it would be necessary to start over, and the losing group would be punished by "taking the top book and taking the model step"!
After the class was divided into two groups on average, the teacher asked a classmate to come to the stage and gave us a simple demonstration, leaving us five minutes to practice. The students in our group practice against the clock. At first, everyone was not skilled and didn't know how to live. After several exercises, they slowly found the trick: facing the person in front, slowly put the straw into the key ring. At this time, the students in front tilted the straw down a little, while the students in the next class tilted the straw up a little, and then the students in front slowly pulled the straw out of the key ring, so it was sent back to ................................... in turn. Sure enough, after several times, our group A lost to the students in group B. ...
This activity class ended in our reluctance, and the interesting game made me deeply feel the importance of unity and cooperation, and unity and mutual assistance can win!
4. Primary school students' third grade composition: pass straws and straws to pass rubber bands.
Changjiang Road Primary School San (3) Banqiu
Today, Mr. Wu took us to play a unique game-passing rubber bands through straws.
As soon as the teacher took out the foreskin tendon, the students straightened up for fear that the teacher would not invite them to play. Then Mr. Wu took out a bag of straws from his bag. Everyone sends one, and each row of hair has a rubber band.
The rules of the game are: the former classmate puts the straw on the rubber band, and the next classmate picks the rubber band with the straw and passes it on to the next classmate. Which row passes first wins.
The game has started. I saw our quarrel. Wang Hecheng passed it to Hu, and Hu passed it to Bi Sheng. Bi Sheng, my turn. You see, Bi Sheng turned to me with a straw and a rubber band hanging on it. I was going to pick it up with a straw, but Bi Sheng accidentally put the rubber band on his mouth, which made it difficult for me to pick it up. I put the straw in the middle of the rubber band and picked it up. Bi Sheng hurriedly drew back the straw, but the rubber band fell off in an instant. I used my quick wits to grab the rubber band that was still in the air, and immediately put it on the straw and uploaded it to Zhang Tianle.
Then, I saw another row of Liu pass it to Banya Arno, and Banya Arno easily passed it to Mao Xueyun. Oh! I admire them for spreading so smoothly!
Oh, great! I forgot to tell you, our group transmitted it. However, failure is the mother of success, and I won't be angry.
This game is really close!
5. The experiment of making bottles blow bubbles One day, I read an interesting thing in a book: under certain conditions, plastic bottles will "drink water" and blow bubbles by themselves. I think this experiment is very interesting, so I plan to do it myself to find out why the bottle "drinks water" and blows bubbles. According to the tips in the book, I prepared the following materials: several flexible straws, a big plate, a cup of tap water, a cup of hot water, a cup of ice water, adhesive tape, plasticine, ink and a big plastic bottle. After everything was ready, I began to do the experiment. First, I sealed the bottle with plasticine, and then I used a straw. Second, I taped another straw. In order to see the experimental phenomenon that will appear clearly, I poured the ink in and dyed the water blue. Step four, I put the big bottle on the plate, bent the straw and inserted it into the tap water cup. The above four steps are only preliminary preparations, and the next steps will lead to experimental phenomena. I first poured hot water on the outer wall of the plastic bottle. At first, nothing happened, so I continued to pour hot water on the bottle and watched the movement of the water cup. After a while, it's time for the bottle to "drink water". I took out half-frozen ice water from the refrigerator and poured it on the bottle wall. At first, it seemed to fail. While staring at the straw, I continued to patiently repeat the action just now. Many things happen. Blue ink really dripped from the straw, and the bottle "drank water"! My experiment succeeded! The scientific truth contained in this experiment is that objects expand when heated and contract when cooled. When hot water is poured on the outer wall of the plastic bottle, the air in the bottle expands when heated and runs into the cup, and the internal pressure increases, so the water pressure in the cup increases and bubbles appear in the straw. Pour ice water on the outer wall of the bottle, the air in the bottle will be cooled, the pressure inside will be reduced, and water will run into the bottle. I also know a lot about the phenomenon of thermal expansion and cold contraction in life, which is really interesting. Students who love brains, let's explore together.

7. Bottle combination that can blow bubbles Today, Uncle Mao Mao and I did an interesting experiment: water that can blow bubbles.
Let's prepare a plastic bottle, some straws, a cup of cold water, a cup of hot water and a piece of plasticine first. "Ready."
"The experiment begins." "I understand."
Uncle Mao Mao and I first sealed the bottle with a piece of plasticine, put a straw in the plasticine, and then reached for the bottle. Then, we put the straw in cold water and poured hot water on the bottle wall, only to see small bubbles coming out of the straw mouth. "It's amazing."
I can't help but praise. "There is even more amazing!" I saw Uncle Mao Mao put a straw into hot water and pour cold water on the bottle wall, only to see the water slowly sucked into the plastic bottle by the straw.
I was in a daze, but Uncle Mao Mao told me with a smile that this is the principle of expansion with heat and contraction with cold. It suddenly dawned on me. A small experiment, but let me know a scientific truth, really not simple.
8. Look at the pictures and write a composition in English. Two goldfish drink water through straws. I have nine little goldfish. Eight goldfish are all orange, and one is black. I like the black one best. We call it blackie. Its body is black. It has big round eyes, a big mouth and a big tail. Although it is big, it swims fast.
I often feed them and change their water. We are good friends.
9. The composition experiment should be done first, and then refer to the examples. The world is changing with each passing day, and new technologies are sweeping the storm of social development. Many things are quietly changing.
However, some of them have been frozen in lost time and become unchanging scenery. What is changing is the increasingly updated technology, and what remains unchanged is the true feelings between people.
Fu Lei's "Letter from Home" is still regarded as a classic, and the heartfelt words are full of love for children. The persuasive teaching naturally flows out of the words of "Letter from Home". These famous sentences "Reading is wise enough, enjoying enough and being talented enough" also give us inspiration.
With the development of science and technology, letters from home have been gradually replaced, but our affection remains the same. A carefully written short message, a cordial greeting and a happy holiday card are all sincere expressions.
These real feelings are irreplaceable by new technology. However, as long as China keeps our friendship, heaven is still our neighbor. It is no longer a distant dream. A telephone call can connect distant friendships.
The true feelings between people last forever in the rapidly developing society. What is changing is the increasingly noisy environment, and what remains unchanged is the innocence in people's hearts.
Social development has brought colorful cities, and the quiet atmosphere has been replaced by noise, but Shi Tiesheng has always maintained his inner innocence. He came to the quiet altar in a wheelchair, isolated from the noise outside and perceived life with his heart.
When many people are chasing fame and fortune, he looks at the world with a sincere heart like a child, forgets the physical pain, and writes attentively, leaving readers with a series of well-known articles that move and support us. The country has become rich, but our hearts can't change, frugality can't turn into extravagance and waste, down-to-earth can't turn into ambition, and self-persistence can't turn into two-sided pleasing.
The environment can be changed, but the innocence in the heart cannot be changed. What has changed is that the fame is getting bigger and bigger, and what remains unchanged is that you don't forget the simplicity of your roots.
The warm sunshine sprinkled on Zhu Zhiwen's dark face, and a thick smile lit up the sky. With his outstanding performance on the stage, Zhu Zhiwen, the "big coat brother", is gradually known by everyone, and his fame is getting bigger and bigger. But he has no "star" at all, and he is bent on carrying out the "grassroots" culture to the end.
A reporter went to interview him, but he has gone back to his hometown to do farm work. His happy smiling face shed hard sweat, which moved many people. Yes, why should it be changed because of external changes? Isn't it the most beautiful attitude in life to "not rejoice in things, not grieve for yourself"? No matter how the environment changes, we can't forget our roots and change our wishes.
Life is getting better and better, technology is becoming more and more developed, and more and more things are changing. But some unchangeable things, no matter how many times they are washed, should remain unchanged and evergreen forever.
Test analysis: This is a material composition question. Candidates are required to conceive and conceive according to the materials. The center reflected by the material is the source of the center of the article. Without the center revealed by the material, they can't write it. Therefore, the material composition is also called "destiny composition", that is, the questioner has provided the examinee with the "basic center (meaning)" of the composition. When reviewing questions, we should grasp the key sentences and focus on thinking.
According to the characteristics of the material content in the topic, the "refining center method" can be adopted. This is the most common and safest way to examine questions in writing material compositions.
First of all, reading the materials carefully, grasping the key words, or analyzing the characters' activities and plot development, and extracting a center from them, as the theme of the article, will certainly make the article both relevant and profound. This material can be roughly conceived from the following aspects: 1. There is no end to learning; 2. Change and invariability; 3. Process and result, method and result; 4. Charm and flexibility of thinking; 5. Relative space and absolute space, etc.
It can be written as a speculative essay or a beautiful essay.
