3. Overall Perception

1. About the Author

Carl Sagan (1934-1996), American, former Cornell Director of the Center for Planetary Research at Waldorf University, he is known as a "popular astronomer" and "public scientist." With his enthusiasm for science and his huge personal influence, he has guided generations of young people on the path of exploring science. He played an important role in sending unmanned spacecraft into space, and also made many achievements in planetary science, the origin of life, and the exploration of extraterrestrial intelligence. He has hosted TV science programs and published a large number of popular science articles and books. His "Dragons of Eden" won the Pulitzer Prize, and the TV series "Cosmos" has received enthusiastic responses around the world. His major works include "Cosmic Connection", "Universe", "Bluca's Brain", "Shadows of Forgotten Predecessors", "Pale Blue Dot", "Billions of Planets", etc.

2. Stylistic characteristics of the commentary

The text is the commentary of a TV film, which has the following characteristics:

(1) The commentary should be According to the characteristics of the explanation object, there should be a clear theme and focus of explanation. It should not cover everything. It should highlight the main aspects of things and grasp the key points of things. Even if it is expanded content, it should not stray from the theme of explanation. If the object of the text explanation is the universe, then the introduction must be based on the composition of the universe, and other questions cannot be randomly raised.

(2) The commentary supplements and increases the relevant information of the explanation object, mainly to expand knowledge and reason, so that readers can accept the meaning that the pictures and objects themselves cannot convey and are difficult to express. For example, the text introduces the basic concept of light years (knowledge expansion) and compares the universe to the sea to stimulate readers' imagination of the universe (emotional expansion).

(3) The commentary is an organic whole, but each part is relatively independent. The text ranges from the universe as a whole to the composition of galaxies and then to the solar system. Although each part is closely connected, it has its own focus and center.

3. Interpretation of the structure of the article

Title: Use famous quotes to indicate the main theme.

1. Explain the significance of human exploration of the universe and the vastness of the universe. (Paragraphs 1-6)

2. Explain the composition of galaxies. (Paragraph 7-11)

3. Explain the nature and number of stars and the possibility of life in planets. (Paragraphs 12-14)

4. Explain the comet nucleus, the solar system and its planets. (Paragraph 15-16)

5. Conclude with the beautiful earth and human knowledge and exploration. (Paragraph 17-18)

4. The explanatory sequence of this article

The explanatory text has a certain visual nature. As the camera lens moves from large-scale space to small-scale space, it slowly advances .

As far as our reading is concerned, the text has been separated from the visual images of the TV (you can also feel the influence of the TV images on the text, such as introductory words such as "We are now back in our backyard"), and it has become an independent article, starting from the order of explanation. Looking at it, the spatial order is adopted:

Universe galaxies (galaxy groups, sub-galaxies) stars, solar systems, planets

The advantage of this order of explanation is:

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

(2) The spatial scale is from large to small, allowing readers to understand the whole, and then go into the details to understand the details. This way, the order is clear and the levels are clear, which is in line with the readers' thinking habits.

(3) From the vast universe, through endless space, and finally return to the home of mankind, this is a process of exploration and discovery, which expresses mankind's admiration for the universe and "controlling our own destiny" "enthusiasm. "The future of mankind depends on how well we understand the universe." Looking back from the universe to the earth is the future of mankind. The order of explanation is consistent with the author's thoughts.

5. The object of explanation and the focus of the explanation of this article

Object of explanation: The object of explanation of this article is the universe, and the purpose is to introduce knowledge about the universe to readers (or viewers).

Key points of explanation:

1. Explain the vast nature of the universe, such as the distance between the earth and the sun, the distance between the earth and the known center of the universe, the distance between galaxies and the distance between galaxies The distance between galaxies.

2. Explain the composition of the universe. For example, there are hundreds of billions of galaxies in the universe. Each galaxy is composed of an average of 100 billion stars...

3. The third important point is speculation. When explaining the vastness of the universe and the composition of planetary systems, the existence of life or advanced animals was speculated twice.

4. Text Interpretation

Understand the following sentences

1. From a macro perspective, most issues that humans care about can be said to be insignificant. , even trivial.

Human beings are small or even insignificant to the universe.

2. These exploration activities remind us that curiosity is human nature, understanding is a pleasure, and knowledge is a prerequisite for survival.

Humanity’s exploration of the universe is instinctive. It is a responsibility that humans must bear if they have wisdom, and it is also the hope of mankind for the future.

3. When we explore the universe, we must have the courage to doubt and be imaginative. Imagination can often lead us to new realms. Without imagination, we will hit walls everywhere. Doubt can free us from illusions and test our speculations.

The courage and quality required for human beings to explore the universe.

4. Because most of the universe is empty. The only typical place is in the vast, cold vacuum of space, in the eternal night of interstellar space.

Most of the universe is void (of course not an absolute vacuum), so humans are very lucky to live on a solid planet.

5. The vast ocean of the universe is boundless and the scope is so large that it is difficult to imagine, and this planet is just one of them, completely submerged in the ocean of the universe. Its existence may only be meaningful to us.

The universe is vast, the earth is just a drop in the ocean, and human beings are even smaller. Human existence may be meaningless to the universe.

6. Our world is full of talents, and people are diligent in learning and asking questions. Our age prides itself on knowledge, and we are very lucky. Human beings are products of the universe and now temporarily live on a planet called "Earth".

Although human beings are small, they are also great. Human beings have proven the value of their existence with knowledge, wisdom and courage.

5. In-depth exploration

1. Question: This article uses a lot of discussion and lyricism. What is the role?

It is clear that the text supplements a lot of relevant knowledge, but What is more prominent is that the author expresses his own thoughts and feelings, including large sections of discussion and emotion. For example, the three paragraphs at the beginning and the two paragraphs at the end have strong argumentative and lyrical colors, integrating reasoning and lyricism, and they naturally match the explanatory text, conveying the author's understanding of the universe and human beings. The discussion and lyricism in the passage can also be seen everywhere, such as "If we are randomly placed in the universe, the chance of us attaching or falling on a planet is only one in 1033. In daily life, such a chance is' Enviable'. This shows how precious celestial bodies are."

2. Question: Human understanding of the universe began from the earth. Why does the author’s explanation not follow the trajectory of the development of human understanding?

Clearly, of course, according to human understanding of the universe It’s not a bad idea to introduce the process of getting to know each other.

The order of introduction 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 stars, and then planets. This introduction facilitates the sorting out of knowledge. Secondly, this is the commentary of the TV movie, from the perspective of photography. It seems that first the whole and then the parts are easier to grasp, but first the parts and then the whole, the expression is easy to be confused, and the visual picture is not easy to coordinate.

3. Ask the author what his understanding of the universe is?

Make it clear that the universe is vast and mysterious. The earth where humans live is just a drop in the ocean of the universe, "its existence may only be meaningful to us." The universe does not exist because of the earth and the humans living on it, but the future of mankind depends on our understanding of the universe.

4. Ask the author what his understanding of human beings is?

Make it clear that human beings are small in the universe, "just a speck of dust flying in the morning window"; human beings care Most of the problems are insignificant and meaningless to the universe; but human beings are brave and glorious. They use their small bodies to explore the vast universe, and human beings develop the greatness of the universe in their smallness.

5. Question: Does the text include a large section of discussion and lyricism that interferes with the explanation of the universe?

It is clear that as a commentary for a TV film, it not only allows the audience to understand the universe The objective composition and related knowledge must also express human beings' subjective understanding of the universe and the significance of human exploration of the universe, so as to infect the audience and stimulate their interest in the universe. Therefore, argumentation and lyricism not only did not interfere with the introduction, but made the introduction more scientific and humanistic.

6. Summary

Through the explanation of many pictures of the universe, the full text shows us the mysteries of the universe, the physical characteristics of celestial bodies and the gains from traveling in space, inspiring the world to explore the universe. The interest inspires the courage and fighting spirit to dedicate oneself to cosmic science and benefit mankind.
