Appreciation of Yin's Works

This is a lyric poem to publicize popular science knowledge. With beautiful language and magical artistic conception, the poet enthusiastically praised the strange talking fossils, showed us the wonders of the mythical biological world hundreds of millions of years ago, and let us know the life information of those extinct creatures and get a glimpse of their charming style. This poem is ingenious in conception, beautiful in language and artistic conception, and very distinctive.

At the beginning of the poem, the poet uses a set of rhetorical sentences, from the individual to the whole, from fish, birds, trees to the whole world, to send out a series of interesting directions, stimulate readers' feelings, activate readers' thinking, and guide us to think and explore the magical world hundreds of millions of years ago. On this basis, the author tactfully used an anthropomorphic sentence: "Can a stone that has been sleeping for hundreds of millions of years talk/sleep?" /Please tell the absurd myths one by one. "Full of passion, clever interpretation, always leading the whole poem. A "sound sleep", a "sound sleep" and an "awakening" make the poem echo up and down, interlocking; The word "please" is very human and makes poetry full of interest.

Then, the poet expounded and recited the fossils in four poems, praised the contribution of fossils, showed us the fantastic biological world hundreds of millions of years ago, and answered our confusion. It is fossils that lead our thoughts back to ancient times, paint us a picture of biological evolution, deny the existence of the creator, answer the ordinary truth of biological evolution, and hide the information of life. It is fossils that enable us to recover dinosaurs and mammoths, making us seem to see their long-necked roaring. It is a fossil that enables us to reproduce ancient trees and see their "lush and elegant" charm. Then, the poet takes the word "ah" as the starting point, expresses his feelings intimately in the second person, discusses lyricism from fossil to nature, and praises nature's "brilliant magician and outstanding sculptor". The poem is beautiful and affectionate. /Cold Skull answers the ordinary truth: "A word is a poetic eye. The poet not only publicized the knowledge of popular science, but also publicized the truth of materialist evolution, making poetry more meaningful.

Finally, the poet made a special poem in the second verse, and skillfully answered it, which produced a kind of beauty that changed. At the end of the sentence, "the fossil that just woke up underground,/what a fascinating and surprising story you told!" It is not only the repetition and repetition of the poetry in the second verse, but also the finishing touch in a natural way, summarizing the whole poem and releasing it in a powerful way. After reading the above, the poet put the whole poem in such a lyrical discussion, which is original and strengthens the main idea. Isn't the story told in Fossil "fascinating and surprising"?

Poetry tells us the fantastic mythological world of fossil preservation hundreds of millions of years ago, praises fossils and publicizes the truth of biological evolution. It contains rich scientific knowledge and materialistic spirit, giving people profound education and enlightenment. It's really commendable!

Yin's speech

I said that the content of the class is Zhang Feng's scientific poem "Petrifaction" in Unit 4, Book 1, Grade 7 Chinese.

First of all, I analyze the content of this lesson as follows: Several articles in this unit of Stone are closely related to science, with rich and colorful contents. Reading these articles can enrich our scientific knowledge and stimulate students' thirst for knowledge.

Requirements of the new curriculum standard: on the basis of understanding the text content, practice summarizing the main points of the text content.

Song of Fossils is about the role of fossils in scientific research: through it, scientists can show us strange pictures on the earth hundreds of millions of years ago. Fossils are indispensable, science is amazing, and scientists are greater.

When studying this lesson, in order to understand the content of the text accurately, we need to contact with the content of biology, such as the evolution of fish, birds, amphibians, angiosperms, dinosaurs, mammoths and so on. But be careful not to explain too much, lest you can't attend biology class.

The text is a scientific poem, which conveys the scientific content in the form of a poem. It has both scientific beauty and literary beauty. In the teaching process, students should be inspired to love science and literature.

According to the above teaching material analysis, considering the psychological characteristics of students' existing cognitive structure, I have formulated the following teaching objectives:

Knowledge goal: 1) Understand and accumulate "fantasy, luxuriance, elegance, seas run dry and rocks crumble."

Rotten, the sun turns and the stars move ".

2) Understand the fantastic biological world revealed by fossils hundreds of millions of years ago.

Ability goal: 1) Understand the content of poetry and appreciate the beauty of rhythm and rhythm of poetry.

Structural features of anaphora.

2) Learn the reading methods of fast reading, screening and summarizing key points.

The goal of moral education: to know the beauty of science, and to cultivate interest in biology and enthusiasm for science.

Teaching emphasis: read repeatedly and feel the beauty of thoughts, feelings and rhythm of poetry.

Teaching difficulties: contact with biological knowledge, activate associative imagination thinking, and deeply understand poetry content.

Second, about teaching methods: To this end, I use the following teaching methods:

1, reading method: poetry has clear rhythm, harmonious tone and rhythmic beauty. At the same time, using anthropomorphic techniques to address fossils with the second person "you" is kind and natural, showing admiration between the lines. You can't appreciate its beauty unless you read it. Guide students to read repeatedly and feel the beauty of emotion and music.

2. Associative imagination: hundreds of millions of years ago, the magical scenes and fossils on the earth were recorded one by one, and scientists restored the image of paleontology accordingly, requiring students to describe the imaginary ancient world according to the materials provided by poetry, and to describe it with beautiful language and organized thinking, which is of great benefit to training students' thinking ability in images.

3. Explore the methods of inspiration: give full play to students' initiative and enthusiasm in teaching, so that students can truly become the main body of learning, and independently explore the content of poetry and the structural beauty of beginning and end.

Third, study legal guidance.

Teaching is a bilateral activity between teachers and students. Follow the teaching philosophy of "teacher-oriented, student-centered, questioning as the main line", and take subjective thinking and group discussion as the guidance of teaching methods.

In the process of guidance, we should first arouse the enthusiasm of students to participate in classroom learning, and then let students think, analyze and discuss independently according to a series of problems closely related to teaching, so as to solve the problems. Students can learn knowledge and improve their abilities from perception to understanding, from sensibility to rationality, and from learning to learning.

Teaching assumption: It is estimated that it will take two class hours.

The first lesson: project and show words, and complete the knowledge goal 1. Show paleontological pictures and complete knowledge goal 2. Read aloud, experience the rhythmic beauty of poetry, understand the structural characteristics of poetry before and after reference, associate imagination, and draw a fantastic picture of fossils.

The second class: give full play to the initiative and enthusiasm of students and explore the content of poetry.

Look for information, write a short article about dinosaurs and advocate poetry.

I take the first class as an example to talk about the specific classroom implementation.

Verb (abbreviation of verb) teaching procedure:

1) Prepare preview in advance: 1) Underline the words you think you don't know or understand, read and write.

2) Be familiar with the text.

2) Well-designed introduction: Students, whenever we walk into the Natural History Museum or see an album introducing paleontology, facing the restored paleontology, our thoughts will always bring us into the ancient world that once left a brilliant life. The cold fossil is the interpretation of life information yesterday, telling the absurd myth hundreds of millions of years ago. Today, we will learn a lyric poem praising fossils-Song of the Stone.

3) The projector displays the prepared words, completes the knowledge target 1, and checks the mastery.

Projecting paleontological pictures into the computer can broaden students' horizons and stimulate their enthusiasm for learning.

4) Teachers demonstrate poems, students pay attention to understanding, and then refer to students to read aloud.

Pay attention to protecting students' enthusiasm, find out the advantages of reading aloud and give encouragement. As for their shortcomings, they communicate privately after class.

Question: Find out which two paragraphs in the poem are similar in structure and what role they play in the content and structure of the whole text.

5) The ancient creatures mentioned in the poem can be said to include the three-dimensional ancient biological world of land, sea and air. What a wonderful picture you should see if we roam to that world in several exploration groups through the time machine. Let's discuss in groups and see which group has a reasonable imagination and a strange and beautiful description. (Ask by group discussion: each group chooses a representative to express the group.

6) Summary: Scientists studied the fossils that preserved the life information of paleontology, from which they got a glimpse of the biological world that was like an absurd myth hundreds of millions of years ago. Poet Zhang Feng praised these strange talking fossils with a scientific poem Song of Stone, and led us to roam the ancient wilderness. I am thinking about how to protect the rare animals on the earth as much as possible, instead of leaving future generations in museums.

course content

Song of Fossil is a scientific lyric poem, which shows the achievements of human research on fossils and reproduces the magical scene hundreds of millions of years ago, thus praising the magic of science and the greatness of human beings. A series of questions in the poem brought people into the fantastic mythological biological world, praising the strange talking fossils with beautiful language. Learning this poem can make students develop rich associations and imaginations, understand the content of the poem and appreciate the poet's feelings.

Analysis on Teaching Methods and Learning Methods

The teaching method of this poem is suitable for the combination of reading and questioning. This poem is a scientific lyric poem with distinct rhythm, harmonious tone and strong musicality. When teaching this article, we should contact the content of biology, so that students can understand what is written in the poem, and read it repeatedly on this basis to feel the beauty of thought, emotion and rhythm. At the same time, through reading, let students search for doubts in their minds and solve them through discussion between teachers and students.

Teaching design

First, import carefully.

1, import with music. Play the music "The Legend of Muyu Stone". The teacher explained: "There is a beautiful legend that a beautiful stone can sing ... it tells kindness ... it tells beauty ..." After listening to this song, the students will imagine how a beautiful stone sings. How does it distinguish good from beauty? There is a poem that says: "Can the world that has passed away for thousands of years reappear to sleep?" Please tell me this absurd myth one by one. "Stone can really tell us a magical story? Let's study a scientific lyric poem "The Story of the Stone".

2. Show the topic and analyze the topic: explain "what is a fossil" and play pictures of fossils for the teacher to explain.

All fossils are biological remains, relics or traces of life, which were buried in the stratum for some reason and gradually formed after tens of thousands of years of complex changes. Therefore, fossils can be used as the main evidence to study the evolution of life on earth. Most fossils are formed by hard parts of organisms, such as plant stems, animal teeth, shells, bones and so on. Some fossils are imprinted fossils of living things, etc. )

Second, the perception of content.

1, what is the meaning of the word "Yin" in the title of this poem, and what is the praise? Please listen to the recording of the text and summarize the main content of this poem in concise language. This poem was written by scientists. By studying fossils, they showed the magical scene hundreds of millions of years ago, thus praising the magic of science.

2, students are free to read aloud, thinking in reading: What did the stone that has been sleeping for hundreds of millions of years say? Please find out the relevant paragraphs, layer the poem and summarize the general idea.

(Poetry is "a little altogether" in structure; It is divided into three layers: Section 1-2 arouses association by asking questions; Sections 3-6 are very detailed and have infinite reverie; Section 7 answers questions and is responsible for the beginning. )

Writing on the blackboard: ask questions, imagine, dream and jump, answer and echo.

Third, independent inquiry.

1, students read paragraphs 3-6 together, find out their favorite sentences and talk about the reasons; You can also talk about the confusion encountered in the process of reading poetry.

Example of problem group:

A. What role does the phrase "You lead my thoughts to ancient times" play in the whole poem?

The thought in the article leads to ancient times, which not only causes the following, but also shows the author's thought.

B. What does the sentence "You deny the existence of the Creator, and the cold bones answer the ordinary truth" tell us?

C How to understand the sentence "Black body wraps the information of life, leaving a precious password for history"

Because organic compounds, as the basic substances of life, remain in fossils, which provides necessary conditions for scientific research.

D. "Time wrinkles your face, just like sketching a life file." Is it about people? How to understand it?

("Carving wrinkles" is a metaphor to describe fossils. Facial wrinkles are portraits of life course. Comparing fossils with facial wrinkles shows that fossils are a witness to the history of the earth, a metaphor, a vivid image and a concrete and abstract thing. )

2. The teacher asked: What rhetorical devices are used in the 1 verse of the poem, and what is its function?

Parallelism rhetoric, through four consecutive questions, strengthens the language potential and has a strong sense of rhythm. It also shows the author's strong scientific interest and thirst for knowledge, and opens the valve of readers' imagination and association.

3, let students read the whole poem again, to further understand the emotions contained in the poem.

Fourth, reflection and expansion.

1. "The world reappears after thousands of years" (showing pictures of ancient creatures reappearing), thinking: Students, what do you feel when faced with the restored dinosaurs and mammoths?

According to the science and technology you know or can design, talk about ways to regenerate extinct species.

How do you feel after learning this poem? This poem expresses the author's admiration for the wonder of science and the greatness of mankind. )

(blackboard writing: magical scenery-the greatness of mankind-praising science)

Fifth, assign homework.

1, write some thoughts after visiting or consulting materials. The topic can be named "Ancient Fantasy-Reading (Watching) ×× Feeling".

2. Be familiar with the text.

Attached book:

Ask questions, imagine-leap-answer, echo

Magical scenery-human greatness-praise science

Further reading

1. Read the poem and answer the questions.

Satellites and answers:

By the way, I was just about to tell you,

I rely on remote sensing technology,

Found the hidden ruins of the ancient city—

It was in the jungle of southern Mexico,

You have two ancient Mayan cities;

There are pyramids in both ancient cities.

There are also various stone buildings.

This eternal ruin,

Its archaeological value is a treasure:

It shows that between 600 and 900 BC,

The prosperity of ancient Mayan culture!

(1) This is what the satellite said to the earth. The technology used in this poem shows the important role of satellite technology in the work.

(2) This is the archaeological value of understanding the history of that time from ancient ruins. Please refer to the resources and give examples to prove this point.

2. Read the passage and answer the questions.

Last June, Pat Leckie, a paleontologist at the Loki Museum in Montana, unearthed a Tyrannosaurus rex skeleton about 12 meter long, which is about 75% of the complete skeleton. Except for a small part of the tail, it is almost a complete skeleton of Tyrannosaurus rex. Based on this, scientists can begin to solve some unsolved mysteries of Tyrannosaurus Rex.

Usually, a Tyrannosaurus rex with a body length of12m, a weight of 3,000kg and teeth as sharp as17.7cm is hard to understand if it is not classified as a carnivore. However, some archaeologists believe that the forelimbs of Tyrannosaurus rex are pitifully short (on a 4.5-meter-long trunk, the forelimbs are only 9 1 cm long).

In order to study the running ability of Tyrannosaurus Rex, scientists conducted biomechanical analysis on the leg bones, pelvis and toe bones of Tyrannosaurus Rex. They measured the tendon attachment on the left forelimb of Tyrannosaurus Rex. According to the size of the bone, the degree of tendon attachment and the approximate muscle mass on the bone, it is calculated that each forelimb of Tyrannosaurus rex can bear about 545 kilograms, which is enough to meet the needs of predation, and scavengers will never have forelimbs that can exert such a powerful force. Besides, scavengers will never have forelimbs.

(1) Fill in the sentences on the middle horizontal line, and the most appropriate one is ().

A. That is the only complete short forelimb and the most complete skeleton fossil.

B. This is the most complete and only skeleton with a short forelimb.

C. that is the only complete short forelimb and the most complete skeleton so far.

D. This is the most complete and only complete short forelimb skeleton fossil.

(2) Researchers have two different views on Tyrannosaurus Rex. The first one is considered as a scavenger, based on: ①, ②, and the second one is considered as a carnivore, based on: ① _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

3. Some succulent fish in the late Devonian may have been threatened by extreme drought, forcing them to try to find new ponds or streams to survive in, which forced them to climb the dry land first. As a result, some carnivorous fish have found new water sources, so they can continue their fish life; Most explorers are likely to die tragically; However, perhaps the most successful are those individuals and their descendants who have learned a new land lifestyle. Since then, they have created a new living space on land, got rid of the restrictions of water on vertebrates, and laid the foundation for a more advanced evolutionary direction.

Suppose you are the first fish to climb ashore from the water, please expand your imagination and try to write a composition in the first person with a self-made topic.

Sharp eyes

1. Judge whether the following statement is right or wrong, and tick "√" for the right statement and "×" for the wrong statement.

(1) "Why didn't the earliest fish have a chin, and why did the earliest birds have mouths and teeth?" Using rhetoric means, it leads to the following situations. ()

(2) "Time has carved wrinkles on your face" uses metaphor and personification rhetoric to show that fossils hide paleontological information. ()

(3) Fossils that just woke up underground uses anthropomorphic techniques to show human's profound understanding of fossils. ()

Specific analysis: These questions examine the understanding of rhetorical devices and their functions. The two questions in the sentence (1) are not rhetorical questions, because rhetorical questions are self-questioning and self-answering, and these two questions are only asked without answering, so they are in the sentence. (2) Compare the traces of life course to wrinkles, and compare fossils to human faces, so √. (3)

Learning prediction

1. Independent investigation.

(1) Design a table to accurately list the types, characteristics and brightness of clouds, as well as the weather conditions predicted by them respectively. The requirements are concise and clear.
