Teaching steps

1. Introduction

Please see the following passage:

Conquest begins with being conquered. For more than 2, years from the 11th century BC to the 11th century AD, the Iberian Peninsula was constantly under fire, and this land was conquered by Romans, Germans and Moors successively. Just like a desperate matador, people living in this land have never stopped fighting against the invaders. Until today, we can still clearly feel the passion for excitement and adventure that seems to be rooted in our genes.

After more than 2, years, tears, pain and sacrifice finally brought precious freedom.

in 1143, an independent monarchy, Portugal, came into being in the war of recovering territory, and was recognized by the Pope. It was the first unified nation-state on the European continent.

Students, please analyze what genre this passage should belong to.

generally speaking, it is an explanatory text, but it is different from the general explanatory text, because we will also strongly feel that there is a strong and rich lyric in it. In fact, this is the first episode of CCTV's 12-episode large-scale TV documentary "The Rise of Great Powers": the commentary fragment of the ocean age. So what are the characteristics of the commentary? Can we also write a beautiful commentary? Today, let's learn about the commentary through the article "The Frontier of the Universe"!

Second, walk into the author

Karl? Carl Sagan (1934-1996), an American, was once the director of the Center for Planetary Studies at Cornell University in the United States. Popular astronomer? And? Public scientist? . With his enthusiasm for science and great personal influence, he led several generations of young people to explore science.

He played an important role in sending unmanned spacecraft into space, and made many achievements in planetary science, the origin of life and the exploration of alien intelligence. He has hosted TV science programs and published a large number of popular science articles and books. His "Flying Dragon in Eden" won the Pulitzer Prize, and the TV series "Cosmos" has received enthusiastic response all over the world. His major works include Cosmic Connection, Cosmos, Bruka's Brain, Shadow of the Forgotten Predecessors, Dim Blue Dot, Billions of Planets and so on.

The Frontier of the Universe is a commentary of a TV film, which is selected from Karl? Sagan's work The Universe. Cosmos has been translated into more than 1 languages and screened in more than 6 countries and regions, with an audience of 5 million. Cosmos, a popular science book matching this TV series, has been the best seller in The New York Times for 7 consecutive weeks, and has the largest circulation among popular science books published in English in history-more than 5 million copies have been distributed in more than 8 countries.

third, browse the full text quickly and think about the following questions

1 What is the order of the explanation of this article? Please write the sequence flow chart.

2 what are the characteristics of the first three paragraphs and the last two paragraphs of the commentary?

3 what does the author know about the universe? What you know about human beings.

IV. Specific analysis

1 From the order of explanation, spatial order is adopted:

Universe-galaxy (galaxy group, sub-galaxy)-star-solar system-planet (earth)

Extension 1: Human understanding of the universe started from the earth. Why doesn't the author's explanation follow the track of human understanding development?

Clear: Of course, it's ok to introduce it according to the course of human understanding of the universe. The introduction order of the text is in line with the law of the evolution of the universe. First there is the universe, then there are galaxies, then there are stars, and then there are planets, so that the introduction is convenient for combing knowledge; Secondly, this is the commentary of a TV film. From a photographic point of view, it is easy to grasp the whole before the part, while the part before the whole is easy to be confused in expression and the visual picture is not well coordinated.

Summary: The commentary features a certain degree of vision, with the camera lens changing from large-scale space to small-scale space.

Extension 2: The basic concept of light-year is introduced (knowledge extension), and the universe is compared to the sea to stimulate readers' imagination of the universe (rational extension). Therefore, the second feature of commentary also shoulders the responsibility of supplementing and increasing the relevant information of the narrator, mainly the expansion of knowledge and reason, so that readers can accept the meaning that the picture and the object themselves cannot be transmitted and expressed.

However, the commentary can't be expanded at will. According to the characteristics of the narrator, it should have a clear theme and key points. It can't cover everything. It should highlight the main aspects of things and grasp the key points of things. Even if it is expanded content, it can't deviate from the theme of the commentary. If the object of the text explanation is the universe, then it is necessary to introduce it closely with the composition of the universe, and other problems cannot be caused at will.

So-Feature 3 of the commentary has a clear subject and key points.

2. Strong arguments and lyrical colors, which are integrated with reasoning and lyricism, and naturally cooperate with explanatory words. In fact, the discussion and lyricism in the paragraphs can also be seen everywhere.

Summary: Features of Commentary 4

Commentary is a style that explains exhibitions, objects, movies, pictures, places of interest and historical relics. Through the accurate description of things and the rendering of words, it infects the audience or listeners, makes them understand the context and significance of things, and receives good publicity results. Therefore, the commentary pays attention to literature and art. It is a combination of explanation and description, which has some characteristics of literature. A good commentary is a touching song and a touching poem. Therefore, a lot of discussion and lyricism will not interfere with the introduction, but make the introduction more scientific and humanistic.

3 what does the author know about the universe?

the universe is vast and mysterious. And the earth where human beings live is just a drop in the ocean in the universe. Its existence may only mean something to us? . The universe does not exist because of the earth and the people living on it, but the future of mankind depends on the degree of understanding of the universe.

4. What does the author know about human beings?

human beings are insignificant in the universe. Just a speck of dust flying in the morning window? ; Most of the problems that human beings care about are insignificant and meaningless to the universe; But human beings are brave and glorious. They explore the vast universe with their small bodies, and human beings are as great as the universe in their smallness.

This actually conveys some humanistic spirit and has humanistic connotation!

1. Introduction: the vast universe. Looking up at the starry sky, there will be many reveries. Are there any aliens? Let's watch a video first. Do you believe in aliens? Ask one or two students to explain the basis of the question. Let's go into the text "The Frontier of the Universe" and see what Carl Sagan, who is called the spokesman of science by Americans, says. Does he believe it?

design intent: to stimulate students' interest and introduce the writing purpose of the article? Explore the mysteries of the universe? . (writing on the blackboard)

2. Question 1: What spirit should we have when exploring the universe?

Dare to doubt and be imaginative (writing on the blackboard)

Design intention: Take two spirits as the breakthrough point of the article and grasp the key of the article.

3. Question 2: Which paragraphs in the text reflect the author's doubts and imagination?

When we look back, we will suddenly find that so many paragraphs mention doubt and imagination. It seems that human beings really need these two spirits to explore the mysteries of the universe. No wonder some people call Carl Sagan? Skeptical Martin Luther King? And doubt and imagine the content? Is there any difference in appearance? Is the social form the same? Intelligent life? Civilization phenomenon? (blackboard writing) is the same as our childhood curiosity, we often say? There are people outside, and there are days behind? In fact, we can also say? The universe is vast and boundless, and it is likely that there are people outside? .

4. Question 3: Does the universe have frontiers? Does the universe have a center?

discuss for two minutes

some students think? The universe has no center, no frontier? Because? The universe is vast and boundless, and the scope is unimaginable? The other part thinks? The universe has a center? Because? 8 billion light years is the center of the universe as we know it? . There are still some who think comprehensively? The universe has a known center and a consistent frontier? According to? 8 billion light years is the center of the universe as we know it? And? The surface of the earth is the Wang Yang coast of the universe? .

Summary: The so-called frontier centers are all within the known range of the exploration of the universe. If our generation continues to explore in the future, the central frontier will change accordingly.

5. Question 4: Analyze the function and language features of a paragraph in the article?

Although such paragraphs do not embody the spirit of doubt and imagination, they provide a knowledge background or the result of doubt and imagination. At the same time, using accurate and vivid language makes scientific knowledge not far away from us.

6. Question 5: Looking at the whole text, why should we explore the mystery of the universe?

It is our duty to continue to explore, and the future depends on our understanding of this universe, so as to find a better home for us.
