There is a fish in the north of the sea, its name is Kun. Kun is so big that I don't know how many thousands of miles it is. It turns into a bird, and its name is Peng. The back of the roc is thousands of miles away. It flies in anger, and its wings are like clouds hanging down from the sky. This is a bird that will migrate to the south if it is transported by sea. Nanming is Tianchi. "Qi Xie" is a strange book. "Harmony" said: "Peng moved to the south of the Ming Dynasty, the water hit three thousand miles, the ball rose up to ninety thousand miles, to six months to rest." Wild horses are like dust, and living things blow each other with their breath. Is the sky still green? Is it too far to reach the extreme? He looked down, and that was it.

Eighth grade second volume,"Zhuangzi two"
"Zhuangzi Two Rules" is selected from Zhuangzi. The articles in Zhuangzi had unique artistic attainments and were unique among the works of the pre-Qin philosophers. The first was 'There is a Fish in the Northern Dark', which depicted the grand scene of a kun transforming into a roc. Kun was an incomparably huge fish in the North Sea. It was thousands of miles in size. When it turned into a roc, its back was thousands of miles in size. When the roc flapped its wings and flew, its wings were like clouds hanging in the sky. When the sea moved and the wind blew, the roc moved to the South Sea. During the migration, it hit the water for three thousand miles, flew to the sky of ninety thousand miles by virtue of the whirlwind, and left by virtue of the strong wind in June. The article also mentioned that the fog in the mountains (wild horses) and the dust in the air were the result of creatures blowing with their breath. This explained the truth that the roc needed to ride the wind to fly, and revealed that the existence and activity of anything needed to rely on certain conditions. The second one was "Chuang Tzu and Hui Tzu Traveling on Haoliang", which described the debate between Chuang Tzu and Hui Tzu about the "joy of fish" on Haoliang. When Chuang Tzu saw the fish swimming leisurely, he thought it was the happiness of the fish. Huizi raised the question of "the child is not a fish, how can he know the joy of the fish", which reflected Chuang Tzu's pursuit of equality and symbiosis with all things and the thought of harmony with the outside world. Huizi emphasized on the judgment of knowledge, the language of debate was strict, the logic was strong, and the attitude of understanding things was to get to the bottom of it. The goals of learning these two articles included using annotations and reference books to dredge the meaning of the text, accumulating classical Chinese words and sentence patterns, combing the content of the article through repeated reading, perceiving the image of the roc and understanding the ideas elaborated in the article, and at the same time appreciating the magnificent imagination and witty debate art of Zhuangzi. The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
Teaching Reflection on the Second Volume of the Eighth Grade in 2021
There were some special and challenging aspects to the teaching of the eighth grade in 2021. The eighth grade was a transition grade, and there were many situations that needed to be dealt with. There were many differences in language teaching compared to the teaching of the higher grades. Although the learning of new words was not the focus of teaching, it was still difficult for some students and could not be ignored. Reading should be the focus, but due to the limitations of students 'cognitive level, it was difficult to grasp the "degree" of teaching. The new teaching materials had a large gap, and the teacher's guidance was sometimes ineffective. In terms of teaching materials, the new teaching materials focused on cultivating students 'learning habits and abilities, but some of the language knowledge requirements were not clear enough, such as the use of punctuations, understanding of various sentence patterns, and sentence training. In the teaching of reading texts, it was necessary to make the teaching goal consistent with the students 'actual situation and avoid teaching too deep and difficult. It was difficult to let the students have something to say and feel. This required the teacher to understand the difficulties and interests of the students, make teaching predictions when designing the teaching plan, and constantly adjust it according to the actual situation in the classroom. In the classroom, teachers should pay attention to the formation of students 'learning habits and abilities. The role of teachers in junior high school is more important. Independent learning also needs teachers' guidance. Teachers should constantly reflect on teaching behavior, improve theoretical level, update concepts, and improve classroom teaching. At the same time, there would be bottlenecks in teaching. For example, students would feel bored if the teaching mode was single, and the effect of composition teaching would be poor. Teachers needed to recharge their studies, read more educational theory books, increase their cultural background, learn from others, reflect on teaching, and improve their grasp of teaching materials and classroom control. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Jellyfish, Biology, Volume One, Eighth Grade
Jellyfish belonged to the coelenterate species and had the typical characteristics of the coelenterate species, such as the body's radiation symmetrical, the surface of the body had stinging cells, and there was a mouth but no anus. In terms of its relationship with humans, jellyfish was edible and had high nutritional value. In terms of reproduction, coelenterate animals (including jellyfish) could reproduce by growing buds. The buds grew into small jellyfish and then shed from the mother to live independently. In the structure of the jellyfish, there were stinging cells in the outer layer. The stinging cells contained thorns and venom, which were sharp weapons for attack and defense. The movement and digestion of jellyfish were related to the commonality of coelenterate. For example, in terms of digestion, the endomorph formed a digestive cavity that was connected to the mouth. Food and digested residue were passed in and out of the mouth. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Eighth grade, second volume of physics knowledge combing
Eighth grade physics knowledge: 1 moves Movement refers to the state and change of an object in time and space. The motion could be divided into uniform linear motion, variable linear motion, curved motion, and so on. 2 Strength Force is the result of the interaction between objects. It can be used to describe the changes in the state of motion of objects, as well as to change the direction and speed of motion of objects. Newton's First Law Newton's first law stated that no object was affected by an external force or was affected by an external force but the acceleration was zero. Newton's second law Newton's second law stated that the acceleration of an object is proportional to the force acting on it and inverse to the mass of the object, which is F=ma. 5 inertia The inertia refers to the property of an object to maintain its original state of motion. That is, an object will maintain a uniform linear motion or a static state when there is no external force. The Law of Movement The law of motion referred to the state of motion and the law of change of an object, including uniform linear motion, variable linear motion, curved motion, and so on. 7 point mass A point mass refers to an object without volume or mass, such as a point of electric charge, a point of gas, and so on. 8 Electric Charge Electric charge referred to the objects with electric charge, including positive and negative charges. Positive charges refer to objects with positive charges, and negative charges refer to objects with negative charges. 9 Electric Field The electric field refers to the electric field generated by electric charges. The strength of the electric field refers to the magnitude of the electric field force of the electric charges in the electric field. Electric Potential Potential difference refers to the energy difference between two electric charges in the electric field. Potential difference refers to the distance between two electric charges. Electric Current Current referred to the power of electric charges flowing in a conductor. The current intensity referred to the amount of electric charges passing through the cross-section of the conductor per unit time. Electromagnetic Induction Electromagnetic induction referred to the effect of a magnetic field on an electric current, which could be described by the law of electromagnetic induction. Electromagnetic Waves Electromagnetic waves were electromagnetic waves generated by alternating electric and magnetic fields that could be transmitted and received through an antenna. The above is some of the key content of the second volume of physics knowledge for the eighth grade. I hope it will be of help to you.
Eighth grade, first volume, biology, boys 'development
Eighth grade biology, second volume, ear structure
The ear is divided into three parts: the outer ear, the middle ear, and the inner ear. 1. ** Outer ear ** - [Ear: Its function is to collect sound waves.] - ** External ear canal **: The main function is to transmit sound waves. There are ear hair and some glands in the external ear canal. The secretion of the glands and the ear hair have a certain blocking effect on foreign objects such as dust. 2. ** Middle ear ** - [Teardrum: An oval-shaped membrane located at the bottom of the external ear canal. It can vibrate under the effect of sound waves.] - ** Tympanic cavity **: It is connected to the throat through the eustachian tube. Air can enter the eardrum through this tube, thus maintaining the balance of air pressure on both sides of the eardrum. - ** Ossicles **: Including the malleus, incus, and stapes. These three ossicles form an " ossicle chain " that can transmit the vibrations produced by the eardrum. - ** Eustachian tube **: From the drum to the throat, it can adjust the pressure difference on both sides of the eardrum. 3. ** Inner ear ** - ** Ear **: There are hearing sensors inside. Under the stimulation of vibration, it can produce nerve impulses and have hearing functions. - ** Vestibular **: There are sensors that can sense the changes in the head position. - [** semicircle canal **: It also has the ability to sense the changes in the position of the head.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The first volume of the eighth grade English is difficult to understand
The important and difficult knowledge points of the first volume of English in the eighth grade included the following aspects: ** 1. Terminology related ** 1. ** Word Memory Method ** - For example,"advice" could be split into code "a d" plus code "v" plus the number "eyes" to remember. - For example,"should" was the combination of "shou" and "ld". - Familiar vocabulary, like "understand" was equivalent to the familiar word "under" plus the familiar word "stand." - For the phrase "write down", you can remember it by writing down some important phone numbers. 2. ** Word Usage ** - "Enough", when used as an adjective, was followed by a verb, such as "enough water" or "enough money"; when used as an adverb, it was used to modify adjectives or adverbs, and was placed after them, such as "good enough" or "run quickly enough". - "Dislike" could be used as a verb, which was equivalent to "don't like" or "doesn't like". It could be followed by "to do" or "doing". As a verb, it could be used to describe something that one didn't like or disliked. - The usage of "as" was complicated. As an adverb, it could be "like". As a conjunction, it could be "like" followed by a sentence, or "when". - "Because of" and "of" were prepositions followed by a verb or a word that was equivalent to a verb (pronoun or gerund). Pay attention to the difference between them and "because"(followed by a sentence that had a subject and a verb). - Some words have different usages depending on their parts of speech. For example,"hungry" is an adjective that can be used as a predicative after a "be" verb (such as "I am hungry"), or it can be used to modify a verb as an attribute (such as "a hungry boy"). - Pay attention to the use of articles for countable pronoun, such as umbrella, which originally began with a syllable, so it is said to be an umbrella. ** 2. In terms of grammar ** - The vocabulary, phrases, sentence patterns, and grammar of each unit were the key points of learning. Not only did they have to memorize them, but they also had to be able to use them. For example, there were some fixed collocations such as "wait for somebody","at the top of", etc. At the same time, the position of different parts of speech in sentences was also important, such as the position of adjectives to modify a verb, the position of adverbs to modify adjectives or adverbs, and so on. ** 3. Unit Focus ** - For example, some of the key words in the first unit (top, wait, umbrella, wet, etc.) and their usage, phrase matching, etc. were all important content that needed to be mastered. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the difficulties in the first volume of the eighth grade English?
The difficulties in the first volume of the eighth grade English were mainly focused on vocabulary and grammar. In terms of vocabulary: - Some words had more parts of speech and complicated usages. For example, when used as an adjective, it was followed by a verb. When used as an adverb, it was placed after an adjective or adverb, such as "enough water" or "good enough." - Some word combinations needed to be remembered, such as "at the top of" and "wait for someone". - Words with similar meanings or similar usages were easy to confuse, such as "arrive in + big place","arrive at + small place", and "because of + name/generation/V-ing","because+ clause". In terms of grammar: - The usage of the infinitive pronoun was more complicated, such as the difference in the usage of some and any (some is mostly used in affirmative sentences, any is mostly used in negative sentences, interrogative sentences, and conditionals, but some is used in some questions because the person asking the question wants to get an affirmative answer from the other person), and the compound infinitive pronoun formed by some, any, no, every, body, one, and thing as the subject, the predicative verb was used as a singular, and if the infinitive pronoun was modified by an attribute, the attribute should be placed after it (such as something interesting). - Similar structures in key phrases are easy to confuse, such as "stop doing something." stop doing something stop to do something forget doing something forget doing something - The position of the adverbs of frequency in the sentence (usually placed before the actual verb, after the be verb or auxiliary verb, often used in the general present tense) and the different expressions of the number of times (once once, twice, three times or more: cardinal number + times) were also difficult. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
