teaching process

First, introduce the new course:

Victor, a great French romantic writer in the 19th century? Hugo has a famous saying: the widest thing in the world is the sea, the sky is wider than the sea, and the human mind is wider than the sky.

How broad-minded is a person? Please let us know the sky first-the vastness of the universe.

To have the broadest mind, please first understand the vastness of the sky-the universe!

Today we study Carl? Sagan's masterpiece "Frontier of the Universe"

Is there a boundary in the universe?

Yes, it is temporary; Every time people explore, the frontier expands once;

No, it's expanding; With the development of human knowledge, it continues to expand.

So in the face of the unknown universe, the initiative is in the hands of human beings. Man is brave and glorious. With our small bodies, we can learn the scientific spirit and explore the future of the vast universe. ...

Secondly, the author introduces:

Carl. American Sagan is the director of the Center for Planetary Research at Cornell University. Known as the "popular astronomer". He guided generations of young Americans to explore planetary science, the origin of life and extraterrestrial intelligence.

His TV series "Universe" has aroused strong repercussions in the world. The popular science book Cosmos with TV series Cosmos has been published in more than 80 countries. It is the best-selling English popular science book in history.

His major works include Dragon in the Garden of Eden, Cosmic Connection, Brouca's Brain, Shadow of the Forgotten Predecessors, Dim Blue Dot, One Billion Planets, etc. His Dragon in the Garden of Eden won the Pulitzer Prize.

Third, quickly read the text, the overall perception:

1. The text is the commentary of a TV movie, which has the following characteristics: (clear object, clear order and beautiful language)

Commentary is a style to explain exhibitions, objects, movies, pictures, places of interest and historical relics. Through the accurate description of things and the rendering of words, the audience or listeners are infected, so that they can understand the context and significance of things and receive good publicity results. Therefore, commentary pays attention to literature and art, which is a combination of explanation and description and has some characteristics of literature. A good commentary is a touching song and a touching poem. Commentary is a kind of written description with pictures or objects. With the help of certain written introduction, the audience can gain a deep understanding. Often appear in sports meetings, parties, etc.)

(1) The commentary should be based on the characteristics of the narrator, with clear themes and key points, and cannot cover everything. It should highlight the main aspects of things, grasp the key points of things, and even the expanded content should not deviate from the theme of the commentary. If the object of text explanation is the universe, then it should be introduced in close connection with the composition of the universe, and other problems should not be brought up at will.

(2) Commentary supplements and increases the narrator's relevant information, mainly the expansion of knowledge and reason, which makes readers accept the meaning that pictures and objects themselves cannot convey and express. For example, the introduction of the basic concept of light-year (knowledge expansion) in this paper compares the universe to the sea and stimulates readers' imagination of the universe (rational expansion).

(3) Commentary is an organic whole, but each part is relatively independent. From the whole universe to the composition of galaxies to the solar system, although all parts are closely related, they have their own emphases and centers.

What should be paid attention to in the writing of commentary?

Commentary should be closely related to the characteristics of the narrator, with clear themes and key points, and should not be comprehensive, divorced from the theme of the commentary and other issues. Commentary should make readers accept the meaning that pictures and objects themselves can't convey and express. We should make good use of the expansion of knowledge and reason.

2. Read the full text quickly and circle the explanatory object of each paragraph. .

3. How to understand the order of this article? (Answer: Is this explanation in good order? Or answer: Why use this to explain the order? )

Get spatial order:

Universe (1-6)- galaxy (galaxy group, sub-galaxy 7- 1 1)- star (12- 14)- solar system (15-/kloc-)

From large to small, from far to near, the whole first and then the part, in line with readers' thinking habits.

There is a universe first, then a galaxy, then a star, and then a planet, which conforms to the evolution law of the universe.

Television commentary, commentary as the camera lens slowly advances, commentary and picture are synchronized and coordinated, and the expression is clear.

Jumping out of the universe can be introduced more clearly and intuitively.

Thinking is used to the universe, and the camera moves forward.

Jumping out of the universe is easy to explain and more clear and intuitive.

Benefits of spatial description:

(1) Although we live in the universe, we jump out of the universe and explain it as a purely objective object, so that we can introduce it more clearly and intuitively.

(2) The spatial scale is from large to small, so that readers can first understand the whole and then go deep into the local details, so that the order is clear and the levels are clear, which is in line with readers' thinking habits.

(3) From the vast universe, through the endless space, and finally back to the home of mankind, this is a process of exploration and discovery, which shows human admiration for the universe and enthusiasm for "mastering their own destiny". The future of mankind depends on our understanding of the universe. Looking back at the earth from the universe is the road to the future of mankind. The order of explanation accords with the author's idea.

Fourth, cooperative exploration.

1. Draw argumentative papers and lyric sentences that you think are more important in the text with curves.

2. How do arguments and lyricism express the author's point of view? (Discussion object+author's point of view)

3. How to understand the function of these arguments and lyric sentences?

Abstracts of argumentative essays and lyric sentences:

1 As long as we think about the universe, we are excited.

Most human concerns can be said to be insignificant, or even insignificant. We human beings are full of vigor and vitality, brave and eager to learn, and have a bright future. Human exploration of the universe reminds us that curiosity is a habit of human beings, understanding is a pleasure, and knowledge is a prerequisite for survival. We are just a dust flying in the morning sky in this universe, and the future of mankind depends on our understanding of this universe.

When we explore the universe, we should be both skeptical and imaginative.

The sea just didn't reach our toes, at most it just splashed our ankles. The sea is charming. The sea is calling us. We were born in this ocean. We are eager to go home.

No planet, star or galaxy is typical. The only typical place is in the vast and cold cosmic vacuum, in the eternal night of interstellar space. This is a strange and desolate place. Planets, stars and galaxies are especially rare and precious.

There may also be creatures, intelligent life and civilization in the universe in the Milky Way.

The universe is likely to be full of life everywhere.

10 The natural laws of the whole area are the same.

13 Our correct understanding of the universe is gradually formed.

14 Some planets may already have advanced animals.

17 the existence of the earth may only be meaningful to us.

Man is lucky to come to the earth. We have the wealth of knowledge accumulated by mankind at great cost for millions of years. Our world is full of talents, and people are diligent and eager to learn. Our times are proud of knowledge. Man is the product of the universe, and now he lives temporarily on a planet called "Earth". Man's long journey home has begun.

Discuss and summarize the main points of lyric sentences;

(1). This paper uses a lot of arguments and lyrical techniques. What's the effect?

Obviously, the writing has supplemented a lot of relevant knowledge, but what is more prominent is that the author expressed his thoughts and feelings, including a long discussion and lyricism. For example, the first three paragraphs and the last two paragraphs are strongly argumentative and lyrical, integrating reasoning and lyricism, and naturally cooperating with explanatory words to convey the author's understanding of the universe and mankind. Comments and lyricism in the paragraph can also be seen everywhere, for example, "If we are left in the universe at will, our chances of attaching to or falling next to a planet are only one in 1033. In daily life, such opportunities are' enviable'. It can be seen how precious celestial bodies are. "

1. expresses the author's understanding of human beings and the universe and the significance of human exploration of the universe.

2. It can better infect the audience and stimulate the audience's interest in the universe.

Teaching innovation

This article is located in the fourth unit of the third module and belongs to popular science articles. This kind of article is theoretical and abstract. The students don't like it, and neither does the teacher. The teaching effect is not ideal. And this course involves a lot of interdisciplinary knowledge, such as geography and physics. If you just study, you can't finish it in the limited classroom time.

On the one hand, as a task, and on the other hand, it can't reflect the subject characteristics of Chinese, so I chose "explanation" as the starting point. "Explanation" is a new content in the new textbook. It is hoped that this course will be used as a carrier, and through cooperative inquiry, students will understand the characteristics of comments and learn to write comments initially.
