Dada and Xiaohu and I came to a stone wall, about two meters high, with only one centimeter of potholes for us to step on. My height1.4m is the tallest among us, and of course I am the bravest. I was the first to go into battle, only to see myself supported by my hands and feet and climb up slowly. When I grabbed the top with my hands, I crossed it with my legs and went up. I added another level and became the commander of 16. Dada also made preparations, and he couldn't get on once or twice ... twelve times. Dada is unconvinced. He insisted on my guidance and finally went up. It's tiger's turn. He said it was too difficult, but he chose to come up. It is also the third time for him to come up.
I see, as long as you make unremitting efforts, you can succeed.
2. My composition about the top ten hazards of climbing a wall This is my resume: Name: * * * Age: 13 years old Height: 166 cm (not bad) Weight: 65 kg (overweight! ) Figure: Super Fat Super Fat
. For a fat and slow-heating guy like me, I stand out among my friends and always do things slowly. No, there's another thing that bothers me-climbing the wall.
I saw several friends crawling from one end of the wall like thin monkeys, and I looked envious. But I don't have the courage to be a monster among my friends. I thought: What should I do? I really envy those little
Partner. If only I could go up there! Even if I go up, I dare not jump down! I face the high wall in front of me, helpless. At this time, my friends cheered me on at the other end of the wall, but I still had it.
Afraid, who made me so fat?
After a long struggle, I finally decided to climb the wall. I didn't expect climbing the wall to be so simple, so I struck out five divisions and two divisions climbed up. Just as I was complacent, another problem came out-jumping off the wall. Faced with such a low
On the ground, I still broke out in a cold sweat. My partners try to encourage me, and I convince myself of my confidence and courage by reducing my losses. I closed my eyes and silently counted: 1-2-3- jump! I jumped without hesitation.
Walking down, although I fell a squat, I was still very happy because I overcame a personal difficulty. Through this incident, I finally understood the truth that "nothing is difficult in the world, and nothing is impossible to a willing mind".
3. How did the gecko climb the wall? Write a composition of 500 words. Gecko is actually one of the best "masters of applied physics" in nature. The strength of its sole actually comes from the most basic physical principle in the universe-molecular gravity. With this power, a 2-inch gecko can theoretically lift a 40-kilogram weight with its sole only a few square millimeters in size!
One seta on the sole of gecko can lift the weight of an ant, while all seta can support the force of 125 kg.
So what is molecular gravity? Molecular gravity, also called van der Waals force, is a weak electromagnetic attraction when neutral molecules are close to each other. Because this kind of gravity is too weak, no one usually pays attention. For example, if we put our hands on the wall, it will also produce molecular gravity, but because the actual contact area is too small, there may be only a few thousand contact points, and people's palms will not be adsorbed on the wall.
But geckos are different. It has millions of extremely fine bristles on each sole, and there are about 400 to 1000 finer branches at the end of each bristle. This fine structure makes the distance between the bristles on the surface of the object and the molecules very close, thus generating molecular attraction. Although the force generated by each bristle can be ignored, it can be accumulated considerably. According to calculation, a bristle can lift the weight of an ant, while 6,543.8+100,000 bristles can lift the weight of 20 kilograms, although their area is less than that of a small coin. If the gecko uses all the bristles at the same time, it can support the force of 125 kg. Scientists say that the gecko can actually support the whole body with only one foot.
Gecko can walk on any dirty surface. Its feet don't automatically secrete liquid, but they have the function of automatic cleaning.
How do geckos control the suction on their feet freely? Scientists recorded the process of gecko crawling on the glass with a microscope camera, and found that when gecko tried to move its feet, it needed to exert 600 times more force than when it sucked the attachments, and stretched its toes to more than 30 degrees to achieve its goal, just like when people tore off the tape. Moreover, even in a vacuum environment, the adhesion on its feet will not fail, which shows that the gecko does not need to secrete anything to maintain the adhesion, nor does it need to "suck" objects with the help of negative air pressure.
Researchers believe that it is possible to develop a new adhesive tape by imitating this structure of gecko soles. It has the advantages of easy disassembly, no damage to the surface of the object and reusability.
Since then, scientists at Lewis-Clark College in the United States have unexpectedly discovered another reason why geckos can easily attach to the surface of objects: they can automatically clean the dirt on the fluff of claws to avoid falling off the crawling surface.
In the past, scientists also speculated that gecko's feet might have the function of self-cleaning, but how it keeps its feet clean and its principle is an unsolved mystery. Geckos never wash their feet, and their feet don't automatically secrete liquid. Keira Aoqiu and Wendy Hansen of Lewis-Clark College studied this magical function of gecko. They found that no matter how dirty the gecko walked on the surface of the object, when it walked a few steps, the dirt on its feet would automatically fall off. They think that after the gecko steps on the dirt, the dirt particles accumulate on the surface of the fluff instead of sticking to it, so the dirt particles will fall off under the action of gravity when they accumulate to a certain extent.
As for the composition about the idea of ants climbing the wall, the homework in the summer vacation of 20 16 is a brainless animal after all. The indomitable spirit is certainly worth advocating, and the thermal steam engine was invented in this way. Now! No matter what setbacks you encounter in the future. So, Watt studied newcomen's invention! Even if it is indomitable spirit, it has climbed up from the root of the wall and never flinched. Two people watched an ant climb the wall with ecstasy and suddenly fell down: "Poor ant. However, after a while, the internal combustion engine diesel engine was invented, but sometimes it should be replaced in time. Everyone should learn from the spirit of compromise of ants. A said that only innovation can be invented; Dissel studied Watt's principle of external combustion engine! Be innovative. Not only now, we can hear and hear the propaganda of "building an innovative society" everywhere: "How tenacious this ant is, we should be smart." B said. In my opinion, only innovation can advance! "yes. As william beveridge, one of the theoretical constructors of the welfare state, said, he did not follow Watt's thought. The change mentioned here is actually "innovation", but the ancients realized the importance of innovation before he went his way. "Only innovation can push history forward and eventually climb halfway. The ants struggled to climb up. " Newcomen invented the pumping turbine.
Hope to adopt. Thank you.
5. ant climbing the wall composition I think everyone has seen such a scene when I was a child. An ant wanted to go to the opposite wall, so he began to climb the wall, but every time he climbed to the middle, he would fall down because of the wall sliding. After each fall, he started from the same place and continued to climb step by step.
This indomitable perseverance of the ant really deserves our praise, but from another angle, is this ant too stubborn? Since the wall is slippery and difficult to climb, why not take a detour, take a slope or find a small hole to drill through? Isn't this a good way? Why does a road come to an end? From this incident, we may be able to see more that when encountering something, it is much more convenient and easier to achieve the goal with clever methods than to use brute force blindly.
When people do something, they have to measure and think before they can find the best way to solve the problem. As the ancients said, "think twice before you act" is very important. Finding a good way to do things is much more likely to succeed than blindly doing it.
It is important to think from another angle and pay attention to your own strengths and advantages. Liu Xiang was a little-known high jumper, but when his coach found that his comprehensive ability of running and jumping was excellent, he advised him to practice hurdling. At this time, he did not stubbornly stick to his original project. Instead, he resolutely gave up his original major at a critical moment and became a professional hurdler, giving full play to his own characteristics and finally winning the Olympic World Championship.
Thinking from another angle, it is also important to be able to make decisive choices at critical moments. In the Eastern Han Dynasty, Ban Chao was just a small official who copied documents in the imperial court. Thinking of Zhang Qian's feat of going to the Western Regions and opening up the Silk Road in the Western Han Dynasty, he was also full of ambition and determined to make a difference, so he decided to join the army. In the career of reopening the Western Regions in the Eastern Han Dynasty, he did a magnificent event and wrote a glorious page in the history of China. Let's imagine, if he keeps plagiarizing articles, can he make a shocking move in the future?
If he only has the fighting spirit of repeated defeats and wars, the consciousness of thinking from another angle, and the self-reflection after failure, then he can only repeatedly defeat and fight, and will never succeed. If you can think carefully before you do something, or after you fail, make a thorough analysis of things, sum up experiences and lessons, and find out good ways, then you may succeed in the end. Through ants climbing the wall, I know that doing things with brains is much better than doing things with brute force.
Of course, the importance of perseverance is undeniable. The relationship between perseverance and methods is interdependent, just like the relationship between learning and thinking. "Learning without thinking is useless, and thinking without thinking is dangerous" complement each other and are indispensable.
Let's learn to do things with our minds, find better ways to do things and create brilliance for our lives!

6. What do you mean by climbing a wall? 1. If you like one idol, but one day you like another idol, it's called climbing the wall.
2. It is also called climbing the wall to find that the person you like has a "close" relationship with other people. 3, reading the post without talking, this behavior is sometimes called diving! The word "climbing the wall" comes from Song Yu, a poet of Chu State in the Warring States Period. See the preface to "The Prostitute Fu of the Disciple". In the mansion, a stunning beauty is lying on the wall spying on the beautiful man Song Yu next door for three years. So climbing a wall is often used to indicate having an affair.
Typical example: In the thirteenth episode of Jin Ping Mei, Ping Li's sister secretly made a peep at the bottom of the spring gap on the wall. "This time, Ximen Qing crossed a desk stool and secretly climbed over the wall. Ladders have been installed here. "Describe the scene of Ximen Qing climbing over the wall to see Li Pinger.
In Li Baichuan's The Wizard of Oz, Zhou Lian and Qi Huiniang also fell in love because of climbing a wall. Huang Tingjian's "Appreciating Plum in Two Rhymes", "Knowing that Song Yu is in the neighboring wall, laughing at the beginning of spring powder", uses climbing the wall to compare the vigorous ecology of plum blossom in the sun.
7. The composition describing climbing walls and roses is 300 words "Jiang Xiang, let's play table tennis!" Xu dui, a neighbor downstairs, shouted. As soon as I listened, I ran downstairs, opened the door and ran out.
"Look, we're going to climb up." Xu Han Zhuo gave me a look and said confidently. I looked up and saw that the railing was about one or two meters long, dark all over, and there was a sharp one at the top. If I am not careful, I may be stabbed by this sharp point, or I may fall down! My heart is uneasy, my heart is like a deer, and I am bumping at random.
He looks like an old hand because of his vigorous skills, and he turned over to me once or twice. "Why, do you dare?" Xu Han Zhuo picked his eyebrows at me. I swallowed and said, "Who's afraid of who?" ! What's the big deal? Not much? "I thought; Hum! This little problem is not difficult for me as a "female heroine".
Do as you say. I stared at the railing and got ready. I put it on the railing and held it with my hand for fear that I might accidentally fall. I slowly raised my feet and put them on the shelf, just like that, and I kept repeating this action. But at this time, my foot slipped accidentally, and I quickly grabbed it to save myself. So, before reaching the last level, I was more cautious.
I raised my foot and put it in the gap between the two tips, but when everything went well, the tips hooked my pants, and I couldn't walk back if I wanted to. I pulled my pants away from the "danger zone" bit by bit by hand. I turned around with my feet carefully. Finally, the exciting moment came, and I succeeded! Yeah! This is so happy.
