junior competition 2021

Junior high school biology experiment operation skills competition was held in many places. There were various contents of the competition. For example, to make and observe the temporary mounting of onion scale and leaf skin cells, one needed to use a microscope, gauze, iodination solution, a drip bottle filled with clean water, a single-sided blade, blotting paper, onion scale leaves, cover glasses, glass slide, tweezers, waste gas bucket, rag, and other equipment. The experimental process included wiping, dripping, taking, spreading, covering, dyeing, observing, sorting, and other steps. Also, observe the structure of the leaves. There are fresh leaves for the experiment.(such as spinach, locust tree leaves), microscope, double-sided blade (Two, side by side, one side glued with tape), tweezers, glass slide, cover glass, permanent horizontal section of the leaf, petri dish filled with clear water, blotting paper, iodination solution, gauze, writing brush, small wooden board, etc. To observe and dissect Crucian Carp, use Crucian Carp (or other fish), scalpel, dissecting scissors, tweezers, dissecting plate, dissecting needle, etc. Observing the structure of fruits and seeds required soaking kidney bean seeds and corn seeds, fresh peaches, blades, scalpels, magnifying glasses, dropper, and iodines. Observing and dissecting earthworms required living earthworms, glass rods, dissecting plates, dissecting scissors, pins, wax plates, cotton balls, and small flashlights. The process of the competition usually included the registration of the contestants, drawing lots to determine the serial number and group, preparation for the examination hall, the start of the competition, the theoretical written test, the judges to change the paper and calculate the results to determine the winner list, and so on. The judges needed to unify the scoring standards in advance. The purpose of holding such competitions included improving students 'biological discipline quality, improving students' practical ability and comprehensive scientific quality, cultivating students 'scientific attitude of seeking truth from facts, laying a foundation for the experimental operation examination of the middle school entrance examination, etc. At the same time, it also helped to improve teachers' experimental teaching level and stimulate teachers 'enthusiasm for innovation in biological experimental teaching. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some common situations regarding the junior high school group of the Youth Host Competition: - ** Group Status **: In the Youth Host Competition of different regions, the division of the junior high school group is usually based on the age range. For example, in the first Junior Host Competition of Gaotang County, the age range of the junior high school group (which can include the junior high school group) is from September 1, 2009 to August 31, 2012. The first youth host competition in Zhaosu County had set up a junior high school group. The contestants needed to show their cultural and artistic accomplishments through multiple links such as self-introduction, talent show, mock hosting, and impromptu commentary. - ** Tournament schedule **: For example, the first Gaotang County Junior Host Competition. The preliminary round includes self-introduction + mock hosting (within 3 minutes). The final round includes self-introduction + mock hosting + recitation (within 5 minutes). - ** Meaning of the competition **: Participating in the competition can help improve the students 'hosting ability, comprehensive quality, and on-the-spot adaptability.

As someone who loves reading novels, I can't get the latest novel content. It is recommended to check the relevant websites or consult the author for more accurate information.

The following are the general writing points of the junior high school biological model competition manual: * * 1. Basic Information ** 1. * * Model Name **: Give the name of the biological model, such as "Plant Cell Model". The name should be concise and accurately reflect the model content. 2. * * Contestant Information **: Including the contestant's school, grade, name, etc. * * 2. Model Design Concept ** 1. * * Knowledge Connection **: Explain the connection between models and junior high school biology knowledge. For example, if you are making a cell model, you can mention that cells are the basic unit of biological structure and function. Making this model will help you understand the functional relationship of the complex structure inside the cell. 2. * * Source of Creation **: Explain the source of the model's creativity, such as being inspired by classroom experiments, extra-cursory books, or life observations. * * 3. Model making materials ** 1. * * List materials **: List the materials used to make the model in detail. For example, the ultra-light clay used to make the plant cell model, colored cardboard, small plastic balls (representing cell organs), etc., and explain the reasons for choosing these materials. For example, ultra-light clay was easy to shape and could be used to make the shape of cells and the rough outline of some organelle; colored cardboard could be used to make the cell wall of cells, because its texture was hard and could better express the structural characteristics of the cell wall; small plastic balls were colorful and round, suitable for representing different organelle. 2. * * The environmental protection and economy of the materials **: If the environmental protection and cheap factors are considered in the selection of materials, it can also be mentioned. For example, the use of waste materials to make models reflects the concept of environmental protection and also shows the wisdom of resource reuse. * * 4. Model Making ** 1. * * Construction steps **: describe the steps of making the model in order. For example, first, use the ultra-light clay to pinch out the rough shape of the cell, then cut out the cell wall with colored cardboard and stick it on the outer layer of the cell. Then, place the small plastic balls representing the different organelle according to the structure of the cell. 2. "Difficulties and solutions in production": Point out the difficulties encountered in the production process, such as how to accurately represent the size ratio of the organelle, and how to solve these problems, such as obtaining accurate data on the size ratio of the organelle by consulting biology textbooks, and then making appropriate adjustments to the production materials. * * 5. Scientificity and accuracy of the model ** 1. * * Structure accuracy **: Explain how the model accurately represents the biological structure. For example, when making the cell model, the shape, size ratio, and position of each cell organ are all made according to the scientific description in the junior high school biology textbook. 2. Function Manifestation: If possible, explain how the model reflects the functions of biological structures. For example, in cell models, the functional characteristics of certain organelle can be displayed through movable parts or color labels. For example, mitochondria is the "power workshop" of cells. It can be made of red materials and a brief explanation can be attached to it. * * 6. Model's aesthetics and creativity ** 1. * * Exterior design **: describe the overall appearance of the model, including color matching, styling design, etc. For example, the color matching is harmonious, which can distinguish different structures and give people a visual aesthetic. The model is novel and unique. It is not a simple imitation, but has its own creative elements. 2. * * The innovation **: The model is more innovative than traditional models, such as the use of new production technology (3D printing, etc.), new display methods (disassembled structure to show internal details, etc.), or unique material combinations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Writing an essay for a junior high school English speech competition could start from the following aspects: ** 1. In terms of structure ** 1. ** Beginning ** - To get the audience's attention, you could use an interesting story, a thought-provoking sentence, or a question. For example, if the topic of the speech was about environmental protection, you could start it with: "Have you ever imagined a world without clean water or fresh air?" Have you ever imagined a world without clean water or fresh air? - Be clear about the topic of your speech and tell the audience what you want to say. For example,"Today, I'm going to talk about the importance of environmental protection." Today, I'm going to talk about the importance of environmental protection. 2. ** Host ** - state one's views or events in an organized manner. If it was a discussion topic, such as the importance of environmental protection, you could list a few sub-arguments, such as "First, environmental protection is crucial for our own health." (First of all, environmental protection is very important to our own health.)“Secondly, it benefits the future generations.”(Secondly, it benefits future generations.) Wait. Each argument had to be supported by specific examples or data. If it was a narrative, it had to be told according to the sequence of events, including the cause, process, and outcome of the event. - Keep it logical and use some connecting words, such as "and","but","however","more","therefore", etc. For example,"We all want to live in a beautiful world, but we are constantly polluting it. However, we can still take actions to change the situation." We all want to live in a beautiful world, but we keep polluting it. However, we can still take action to change the situation.) 3. ** Ending ** - He summarized the main content of the speech and emphasized the key points. For example,"In conclusion, environmental protection is not only a responsibility but also a necessity for all of us." In short, environmental protection is not only a responsibility but also a necessity for all of us. - Ending the speech in a forceful way could be an appeal, such as "Let's take action right now to protect our environment!" Let's take action to protect the environment now! Or a vision, such as "I believe that with our joint efforts, our earth will become a more beautiful place in the future." I believe that through our joint efforts, our earth will become a more beautiful place in the future. ** 2. Language ** 1. ** Words ** - Try to use accurate and rich vocabulary. Try to avoid repeating simple words. If you often use "good", you can change it to "excellent","wonderful","magnificent", etc. according to the context. - Accumulate some professional vocabulary related to the topic of the speech, such as "pollution","recycling","sustainable development", etc. under the theme of environmental protection. 2. ** Sentence Patterns ** - In addition to simple sentences, some compound sentences can be used appropriately, such as attributive clauses (I like the park which has a lot of trees. I like the park with a lot of trees.) When we protect the environment, we are protecting ourselves. and so on to increase the complexity of the sentence. - You can use some fixed sentence structures to increase literary grace, such as "It is + adj.+ for sb. to do something." it's Not only good for someone to do something but also...”(Not only…but also…) At the same time, you can also use a negative word plus a 'without' construct (as in I can't succeed without your help.) This kind of more advanced sentence structure made the essay more outstanding. 3. ** Avoiding mistakes ** - Pay attention to the correct grammar, including the agreement of subject and verb, correct tenses, etc. For example,"He likes reading books." (Not 'He likes reading books'.) "I went to the park yesterday." (Not "I go to the park yesterday") - Pay attention to the correct spellings and check them carefully after writing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The speed reading competition was a competition that tested the reader's ability to read and understand quickly. Usually, speed-reading competitions require participants to read a large amount of text in a very short time and try their best to understand its meaning and gist. This kind of competition usually involved a variety of novels, essays, poems, and other literary works. Therefore, the contestants needed to have certain reading and comprehension skills and abilities. Some speed-reading competitions also required participants to switch between speed reading and intensive reading to better understand the content of the text. The speed reading competition was designed to improve readers 'reading efficiency and comprehension ability, and at the same time, provide new ideas and inspiration for literary creation.

As a fan of online novels, I don't have any updates on novel competitions or original online novel competitions. However, they could use search engines or related novel websites to inquire about the latest novel competitions and original online novel competitions.

I recommend " The All-Rounder," which was a novel about sports events written by someone who had overcome all obstacles. The protagonist was an all-rounder, proficient in all kinds of sports, and broke records in the Olympics. This was the first creation of the all-around competitive style, and its creativity was superb. The description of the sports background and sports techniques in the book was not bad. It was good to grasp it well, but the character creation was a little weak. There were too many sports events in the later stages, and the emotional description was stiff. However, it was a good niche sports novel with more than 10,000 orders. The first part was exciting and the book was in short supply. I recommend Dleer's " The Ball is Beneath Your Feet " and " Victory is in Your Hand." These two books were sports and football novels. The author really knew football. He could clearly explain the characteristics of the players and the configuration of the team. It was a work with practical content. Although the author's writing style was dry and did not know how to create an atmosphere, these shortcomings could be ignored if one read competitive literature. One could also learn a lot of football knowledge from it. " I Really Don't Want to Be the Director of a Mental Hospital " was a sci-fi evolutionary novel written by Dubhe. The story was interesting, and there were many characters. The character information was clear. Those who liked this type of sci-fi story could read it. League of Legends: I am Captain was written by Wasai, a gaming and esports novel. The protagonist was a golden rookie who took the training system back to the LOL period of S2 and joined We to build an independent team to fight in the league. The novel had its own characteristics. The talents of each team were summarized in place. The golden finger was neither too big nor too small. It looked pretty good. LoL fans could give it a try. " Reborn: Hot Blood Ping-Pong " was a novel about sports events written by Xi Baisha. The protagonist was reborn as a professional ping-pong player, and it was very enjoyable to write. Table tennis was a rare theme, and it was a unique existence on the sports channel. If there was a shortage of books or if you wanted to change your taste, you could watch it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
