The Frontier of the Universe PPT, Part 2: Stylistic Characteristics of the Commentary

(1) The commentary should have a clear theme and focus of explanation based on the characteristics of the explanation object. It should not be exhaustive. It should highlight the main aspects of the thing and grasp the key of the thing. Even if it is an expanded content, it should not stray from the theme of the 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 emotions, allowing readers to 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, stimulating 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.

The Frontier of the Universe PPT, Part 3: Thoughts and Discussions

In what order does the author introduce it, and summarizes the main content of each part.

Judging from the order of explanation, the author follows the spatial order, advancing from large-scale space to small-scale space. The first part introduces the universe and explains the significance of human exploration of the universe; the second part introduces galaxies; the third part introduces stars; the fourth part introduces planets and solar systems; and finally returns to the home of mankind.

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 goes from large to small, allowing readers to understand the whole, and then go into details to understand the details. This way, the order is clear, the levels are clear, and it is in line with the readers' thinking habits.

(3) From the vast universe, through endless space, and finally back to the home of mankind, this is a process of exploration and discovery, which reflects mankind's admiration for the universe and enthusiasm for "controlling our own destiny." "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.

The Frontier of the Universe PPT, Part 4: Understand the following sentences

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

Human beings are small or even insignificant to the universe.

2. These explorations 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 due to their wisdom, and it is also the hope of humankind for the future.

3. When we explore the universe, we must be both skeptical and 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 assumptions.

The courage and qualities 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 the universe, 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.

The Frontier of the Universe PPT, Part 5: Writing Reference

The plain explanation is extremely scientifically accurate. This article uses numerical illustrations in almost every description of celestial space. Otherwise, people will be confused about the characteristics of celestial bodies.

Vivid descriptions enhance the readability of the article. A large number of metaphors vividly present unimaginable scenes of the universe to readers, enhancing the readability of the expository text.

The writing of this article has great jumps, but the whole article is very layered. This is the biggest feature of TV commentary. It must change the content of the description at any time with the TV screen.
