I have observed spiders for a while and found that most spiders are not pests, but they are very beneficial to human beings! They caught a large number of pests in their own unique way. As far as I know, there are two ways to catch insects: the first is the "waiting for the rabbit" method. It first weaves a gossip-shaped sticky net with silk in its belly, and then hides in a corner that is not easy to be found, waiting for the arrival of flying insects. If some unlucky flying insect hits the net, its body will get stuck and can't move. At this time, the spider will quickly climb over, bite the prey and inject "anesthetic" into its body to turn the internal organs of the prey into liquid. And finally? Dinner, of course! I have only seen the second method of catching insects once, and I don't know much about it. This method of catching insects is relatively simple, and there are not many prey caught: it will pounce on its prey like a beast. At the speed of spiders, it is ok to catch some reptiles that can't fly, but what about those flying insects? Will greatly reduce the discount!
In addition, spiders are also excellent meteorologists. On a sunny day, it lazily basks in a large horizontal net. Of course, if it can stick to an insect, it will be an unexpected gain for spiders. On rainy days, spiders will leave the horizontal web and weave a vertical web in another shelter. When you come back after the rain clears, you will find that the horizontal net has been smashed by raindrops, but the vertical net is intact. According to this phenomenon, we can know that it will be a sunny day when spiders make horizontal webs; When spiders spin vertical webs, it will rain.
After this introduction, you should know something about spiders! In fact, my observation is only one-sided, and spiders also have pests. Do you want to know? Please use your head and observe more. If anyone knows more about spiders, please communicate with me to enrich our knowledge.
Hope to adopt.
2. The composition about spiders 180 words, urgent "ah-spider!" A female classmate screamed while reading aloud, pointing to the ceiling. Many people stopped reading and looked at the ceiling with her fingers. I also looked up at the spider. That spider is different from what I usually see: huge body, furry eight feet, crawling quickly on the ceiling. The teacher is still standing on it. I put my Chinese book on the table and continued to look up. The spider climbed to a corner and built its nest there. I really don't know. Why did you stay there? A few minutes later, it spit out a thin and long silk, hanging from the ceiling, just above the right of the computer desk, scaring some female students to shout: "The spider fell, ah-"This cry finally attracted everyone, and everyone began to pay attention to the spider's next move. My heart hangs up: will that silk break? What if I fall to the ground? Will you climb to my feet? A gust of wind blew and the spider silk was blown around. The heavy spider kept paying, stretched her legs and reached the computer desk. The spider broke free from its spider silk and crawled out of the computer desk, but I don't know where it went. Ha! It is clever to "overtake" such a short road in such a convenient way. Without this method, no one knows how long it will climb. You have to climb from that corner to the ground, then climb from the ground to the computer desk, and then escape from the window. Animals are certainly not as clever as people, but now spiders seem to be beyond our imagination. That spider is probably the cleverest spider I have ever seen.
Modify it yourself.
Today, I played ball in the yard. Suddenly, I saw a net with an Okumo on it.
This Okumo is a bit scary-it is as big as a walnut and its legs are three centimeters long, which is longer than its body. I saw that spider seemed to be sleeping, but when I looked carefully, it was moving, not sleeping. After a while, it began to walk around on its own internet, as if taking a walk.
I thought it was very interesting, so I caught an ant and threw it on its net. I saw this Okumo, like a bullet, running to the ant's side in a second. This Okumo pointed her head at the ant and bit it in half. Then, this Okumo swallowed its food bit by bit.
After eating the delicious food, it stayed on the internet and waited motionless. Suddenly, another fly flew to its net. This time, however, Okumo didn't eat the fly like he ate ants last time. Its hand seems to be spinning around the fly like magic. After a while, the fly turned into a white ball. Finally, Okumo slowly pulled the fly back to its nest.
I picked up another bug and threw it into the cobweb. Compared with Okumo, that bug is like a grape and a watermelon. Only the watermelon opened its mouth and swallowed the grapes in one bite.
I went back to my room and looked through the encyclopedia. I found that this kind of spider is called spider. This spider should be a male, because the book says that it is about 20 mm long and its web will be round at dusk, so it is called a spider.
4. Composition: Spider's self-report 700 Hi! Hello, I'm a spider.
Hey! Don't go, don't be scared by my appearance. I am ugly, but I am smart. Do you know who Zhuge Liang with eight feet is? That's me.-Spider! I have heard a lot, but I have never heard of it. Gender: male.
Unmarried, although we spiders are just two words, in fact, there are many contents! I have millions of compatriots! Because we are very adaptable.
Of course, I still like this place best, the water town in the south of the Yangtze River. The climate is warm and humid, so I won't worry about what I eat! Weaving webs is our spider's innate ability. The silk that weaves the net is secreted by the textile glands in my abdomen.
Young spiders float to the mountains with hairsprings, and hunting spiders wander around to hunt pests, so they usually leave some "clues" in the places they pass. Spiders like us use tough and elastic silk to build their homes and live a stable life.
I am still single, because after we get married, spiders will be eaten by female spiders, in order to have baby spiders with them! We don't have any feelings. We only got married for the next generation, and I want to live a few more months. But because of different habits, we repair houses according to our own needs: awning nets, funnel nets, basin nets and so on.
My web is wheel-shaped and radial, just like the "gossip" of human beings! So I'm a little skeptical: was the inventor of "Bagua Array" my ancestor? I, a spider, never picky about food. In fact, we spiders eat a wide range of insects, such as centipedes and earthworms. One of my cousins has eaten birds! I really don't know how it tastes.
I am not only clever, but also gentle and patient. I won't be like a wolf or a tiger when "goods" come to my door. I have to add some seasoning-anesthetic to my food first, and then I will eat it after those bugs paralyze me.
If you encounter a big bug, you will have to go through more difficulties. Especially the guy with armor, with great effort, finally tied this foot with silk, and that foot came out again.
To make matters worse, once, the beetle I had tied for a long time struggled to escape from the net. I really lost my "food" and "home", so I could only watch it fly away and come back helplessly to mend the net.
Hearing this, do you think our spider business is so easy to do? No, no, no. In fact, there are quite a few dangers we encounter. For example, if you meet food with a javelin, it tastes delicious, but you should always be on your guard. If he throws the javelin, you will "die with him".
This is not very difficult, just be careful. If you meet a newt, it's a narrow escape.
It touched it gently on the internet first, and when we got the information and went out to watch it, it took us away for dinner. However, spiders have their own nature, and I am still alive! Ha ha! "Shh ..." The net shook again, just right. I'm a little thirsty. Wait a minute, wait till I get back.
I'm going out first. "Ah, it's a salamander! Help! " "Oh, my God! Why don't you even let me drink the last sip of water and let me die! " .
5. Take the sports meeting as the center and write a composition with action description. Today, the sun is shining, and our school held the spring track and field meeting.
Looking around, the students sitting safely on the playground, as well as the eager athletes, are all excited. Listen! The deafening drums and trumpets on the playground made us jump for joy.
The shouts of students have become the source of motivation for the athletes who will play. Bang, the 60-meter sprint began, and all the students in Grade One and Grade Two sitting next to them were very excited.
Shouting "Come on, come on", the athletes chased each other and sprinted bravely. Whether they succeed or not, they still don't lose heart and strive for the first place. I am really proud of them.
The 400-meter race has started, and all the students are desperately cheering for the athletes. Suddenly a familiar figure appeared, a little athlete. I stood up excitedly and shouted "Come on! Come on! " In the cheers of all his classmates, he struggled to run forward, fast, fast, and it was almost the end. This is the final sprint stage, and it is a crucial moment to decide the outcome.
The cheerleaders in the audience were all flushed and shouted "Quick! Quick! " , "Come on! Come on! " Some students simply stood up and jumped to cheer for them. Sure enough, this classmate lived up to expectations and won the first place. Suddenly, cheers rang out on the playground.
Look, after the graceful run-up, the high jumpers jump, draw an arc in the air, sink quickly and close their feet. After that, he excitedly waved his fist and ran to the teacher for a big hug. His face is full of joy.
Yes! Every jump is a challenge and a transcendence. Nothing can't be surpassed as long as you do it boldly. The most interesting thing is definitely the teacher's relay race. Female teachers are dignified and elegant at ordinary times, and they are desperate when they arrive at the competition site. Although I don't run too fast, I work hard all over my body, and my tenacious struggle has lost my gentleness and kindness in class.
It's the male teacher's turn. They are all "Scud". The fastest one must be Mr. Li. He came running like a gust of wind, faster than a rabbit. The funniest thing is the director. He was the last one. When he runs, his head and neck shake back and forth greatly, which is particularly interesting. In the cheers and cheers of his classmates, he took the lead in crossing the finish line and won the first place.
This sports meeting is not only a big stage to show students' physical quality, but also a platform to promote inter-school friendship. This is really a wonderful and United sports meeting.
6. The 700-word character description fragment of the writer's composition shows her dark face, revealing an indomitable character. A pair of glass ball-like eyes sparkle under her thick black eyebrows, carefully observing her opponent's every move, alert and flexible.
The uneven outline outlines her unremitting pursuit of table tennis. Although she is short and not strong, she is still crazy about sports.
Just like her shocking name-Thunderstorm Point, the thunder keeps coming! Action description A black spot suddenly appeared in the center of the moon, and the black spot became bigger and bigger. I opened my eyes in surprise. The black spot suddenly turned into a slender figure and landed on the opposite high building. The big black trench coat fluttered in the air, and the slender figure wanted to break the wind. Against the background of the full moon and space, this picture exudes a strong strange and charming atmosphere.
Aunt rolled up her sleeves and rolled up her trouser legs. She moved slowly in the stream, raised her left foot slightly, took a small step forward, and dragged her right foot forward slowly, as if wearing a thousand-pound shoe.
She twisted her hat, hunched her back, lowered her head, narrowed her eyes, and her hands seemed to be holding something. At this time, she stopped, stopped looking around, stared at a place on the right, and suddenly reached into the water with a small fish in her hand.
Near, near, the team leader finally came to his side, standing in front of him like a Mount Tai, shouting, "Hand in your homework!" " "He" hey hey "smile, expression is so funny, it is so mysterious, all of a sudden, he plunged down, like a slippery loach broke free from the group leader's arm, feet like oil ran away.
7. Motion scene description composition is 700 words. In this crisp September, we are facing the autumn sunshine and ushered in a cheerful and wonderful school sports meeting in the harvest season.
Early in the morning, all the teachers and students came to the playground. Some of them decorate venues, some decorate clothes and some put sports equipment. They were very busy, and the originally silent stadium suddenly became lively.
With the announcement of the official start of the sports meeting, all classes of teams entered the stadium in turn. At this time, the March suddenly sounded, and one class after another lined up in neat formation and strode to the rostrum. They are all well-dressed, smiling and strutting, showing the unique vigor and vitality of young people.
When the conference announced the official start of the sports competition, the whole stadium suddenly boiled and cheers came one after another. Watching the athletes in the track and field field fly away from the starting point like rabbits and rush to the finish line like sharp arrows, attracting the audience present. Whether the players win the first prize or not, they will be praised and encouraged by the audience. Because in the hearts of the audience, these athletes have played an indomitable and tenacious spirit of sports. They are heroes in sports and "Liu Xiang" of XX school. Women's 800m and men's1500m are events that test athletes' physical strength and perseverance. Although not as exciting and exciting as sprinting, it is definitely more touching than sprinting. In the competition, players have to face not only physical tests, but also psychological tests. The athletes who participated in this project truly embodied the spirit of hard work and never giving up, and gave us much richer feelings than their achievements.
Look at the athletes in the track and field, all rubbing their hands and showing no weakness. In order to get better results, high jumpers do their best and never give up even if they fail. They took firm steps towards the goal and jumped again and again. This spirit of constantly surpassing oneself is a huge personal wealth and a solid cornerstone for going higher and further in the future. Players participating in the shot put competition compete with each other and get farther and farther. The shot put in their hands seems to have turned into a wishing ball full of hope, constantly chasing their dreams.
The sports meeting showed the students' youthful demeanor and tested their physical and mental practice. It exercises physical strength, activates life, enhances personality and youthful vitality, and gains a smiling face and mental outlook. All the athletes have made achievements in this sports meeting, displayed their elegant demeanor, carried forward the spirit of friendship first and competition second, found more glory and dreams in the competition, and created more beauty and glory in the competition.
Students learn to compete, cooperate and communicate while enjoying hard work and happiness. At the sports meeting, we can get a lot of things, the most important thing is not ranking and honor. Some may be more valuable than these, such as friendship, help and sincerity between people.
8. Write a 700-word composition with details. Perhaps it is because physical education class used to be free to move around, so all the students in our class like sports very much.
This is another brand-new physical education class. To our great dismay, the PE teacher was replaced by a short and fat Mr. Tang, who didn't know what new things would be used to greet us.
I came to the basketball court and learned that I was going to leapfrog today! Some people are in high spirits, but I am sad. Who doesn't know that leapfrog is very laborious? This distance is still far. Divide into four groups, the first group goes on stage. Those boys who were full of confidence at first forgot their "confidence" as soon as they got on the court. Look at Lu Zhijie's nervousness. He can't even jump 50 centimeters a step, so he knows it's not easy. It's finally my turn to play. When the teacher calls for preparation, shake your hand vigorously and get ready to take off. At the beginning, everyone was desperately breastfeeding, push forward. I'm not to be outdone. Bite your teeth, stretch your feet, close your eyes and jump to the finish line. There are still a few steps, and persistence is victory. Finally, I struggled to reach the finish line. Although my feet were numb, I got the joy of success. Have a rest, and we will start the second leapfrog. Everyone looked up and shouted out their hearts: "Oh, my God!" Really complaining. However, this round, everyone has already understood the "hidden rules." Pay attention to fast and good, and don't finish the task. Go! At the moment when we stood on the same starting line, some experts were far ahead, and there was still half way to the finish line. We are flushed and exhausted, and it is inevitable that some people will be impatient. One person stops jumping, and one person stops jumping with another person. "If you can't bear it, it's a mess." There's nothing wrong with that.
After a few come back, even pick Jin Xian may not survive. With Mr. Tang's permission, we were dissolved. Frog jumping is a little tired. It can be seen that we all like it because it is a new thing.
