What we have just seen is the whole process of human visiting the moon, so how did the author Zhu Changchao record this real process with his notes? Today, let's experience the thrilling moment of 1969 with space heroes. ...

Design III (background music: Beethoven's Moonlight Song, A Bing's Two Springs Reflecting the Moon)

Students, accompanied by the familiar nursery rhyme "a curved moon, a boat, a boat with two pointed ends", we unconsciously passed through childhood. Indeed, the washed blue sky and full moon are eye-catching, and the rich connotation lies in myths and legends, lyrics of articles and folk customs. The lonely Chang 'e with long sleeves and the sound of WU GANG chopping laurel all tempt people to imagine the situation on the moon. The wonderful fantasy finally spread its wings and flew to the moon with Apollo11"-1969, the space eagle of Kennedy Space Center in the United States. Today, let's relive that moment under the guidance of Zhu Changchao. (blackboard writing, author)

This article is a popular science essay, which truly records the whole process of the first moon landing. In this paper, select and circle the phrases that represent time, and think about:

(1) The whole process of landing on the moon can be divided into several stages according to time development and spatial position. Try to summarize the main points of each stage. Use a schematic diagram to mark the journey of the spacecraft to the moon (indicate time, distance, speed, etc. ).

Students discuss and answer, and the teacher makes it clear:

The whole process of landing on the moon can be divided into four stages: preparation before launch, spacecraft flying to the moon, successful landing of the lunar module and spacecraft returning to the earth.

(2) In what order did the article report the whole process of landing on the moon?

Explicit: Described in chronological order. Clear time clues enable readers to know the specific time of landing on the moon in detail, and also enhance the vividness of the event.

3. The named students retell the event process in detail and ask for specific details. The rest of the students supplement the missing' plot'.

What did the astronauts do after landing on the moon? Mark it in the text.

The astronauts did the following things after landing on the moon:

(1) Check the landing of the lunar lander;

(2) collecting moon soil and moon rock samples;

(3) Setting up a moon landing monument;

(4) install TV cameras, solar wind measuring devices, laser instruments and lunar seismographs for scientific exploration;

1969 July 16, the Kennedy Space Center in the middle of Florida Peninsula, USA, astronauts Armstrong, Collins and Aldrin.

6. Read and recite the last paragraph of Armstrong's comment on the significance of landing on the moon.

7, teachers and students * * * with the text idea:

The article adopts the structure of "summary-comment" (blackboard writing):

The first part: An overview of the moon landing event and its significance.

Part II: Comment on the whole process of landing on the moon.

The first stage: take off. The second stage: March.

Stage 3: Landing on the Moon Stage 4: Returning to the Moon

Part III: Re-emphasize the great significance of the moon landing event.

8, imagination training:

According to the situation, expand your imagination and describe a segment orally.

You are driving a spaceship, looking for alien life in the vast space. It's been several days since you left the earth. At this time, through the porthole, you see a beautiful blue planet. ...

Third, read the text intensively and discuss the details.

1. Let a student read the fifth paragraph of the text. Other students mark sentences with numbers in their textbooks. Thinking: What is the function of a series of figures listed in detail by the author?

The teacher is very clear:

Attractive figures, such as "Apollo 1 1", are 2650 kilometers high and 7.67 kilometers per second; 2 1 morning, 1 1: 39, the door of the lunar module is opened; 1969 July 2 1 day 1 1: 56: 20, etc.

Because this is an article about space exploration, space exploration requires very high precision of numbers. These figures are mainly to reflect the accuracy, scientificity and authenticity of this article, to reflect the characteristics of factual reports and to help readers increase their knowledge.

2. Discuss the argumentative sentences and the contents of the projection display in paragraph 4 of the text: Why is the first moon landing a "great leap for all mankind" and a milestone for human exploration of space?

Projection:

(1) This small step is a small step for a person; This is a huge leap for the whole mankind.

The first step on the moon is to set foot on the planets in the solar system, and finally on other planets in space. "One small step for one person" is a fact, and "One giant leap for all mankind" is a hope for the future.

(3) 21~ In the 22nd century, human beings will emigrate to the moon and establish the Moon Village. Moon Village will use solar energy for heating, use the water found on the moon to produce vegetables and grains, and establish various living facilities. The important task of Moon Village is to mine helium 3 and transport it back to the earth, and use this heat energy to generate electricity and supply the electricity needed by the whole earth. Humans will also develop tourism and let the people of the earth visit the Moon Village.

Students speak freely and answer freely, and the teacher gives a hint: "One small step" refers to a small step for astronauts to cross the surface of the moon from the spaceship, which is a statement of facts. However, this small step is the first step taken by mankind in the field of space. It shows the outstanding intelligence of human beings, and indicates that modern technology has reached the development level of outer space, and the pace of human beings entering the universe will be more solid and longer.

The author recorded the process of landing on the moon in plain language. Although there is not much lyricism, what thoughts and feelings does the author express between the lines? Give a segment description.

Clarity: It expresses the author's joy and admiration for human intelligence and astronauts.

Such as the victory and heroic feelings revealed in the moon landing monument.

Fourth, class summary.

More than thirty years ago, man successfully landed on the moon for the first time. Looking back at the history and revisiting the classics, while marveling at the great achievements of human beings written with wisdom, the mystery of the moon still attracts the pace of human exploration, which is pregnant with the creation of wonderful myths. We have reason to believe that in the near future, the dream of Moon Village will become a vivid reality. Let us pray for a better future for mankind.

Verb (abbreviation of verb) classroom practice

Read the passage and complete 1 ~ 4 questions:

Projection:

Apollo 1 1 The moment when the spacecraft landed on the moon for the first time was really amazing. But the spacecraft must get rid of the strong gravity of the earth before it can fly to the moon. Therefore, the first few minutes of launch, that is, within a few kilometers of the beginning of the whole voyage, are the most difficult moments, and the power consumed often exceeds hundreds of thousands of kilometers in the future.

Habit is the same, it has a great "gravity", but many people don't pay attention to it or refuse to admit it. If we want to get rid of bad habits such as inflexibility, impatience, picky, selfishness and lack of willpower, we can't carry out drastic reforms, so it is difficult to do everything. It takes a lot of effort to take off, but once we get rid of the fetters of gravity, we can reach the ideal situation.

1. From the full text, what does the first paragraph mean about the spaceship? Answer with sentences in the text.

At 9: 32 pm on July 19, it was sent from the ground command center.

Shout (shout, save, shout). Three people got up quickly. On this day, they should land on the moon as planned. The spacecraft began to fly (average speed, deceleration, acceleration), and it won't be long before they reach the long-awaited moon. Three astronauts worked nervously, holding joysticks in their hands to prevent manual operation in case of computer failure. Fortunately, the computer gives normal instructions, and when the spacecraft slows down to a certain speed, it automatically gives a cease-fire instruction. At 7: 32 am on July 20, Armstrong and Aldrin put on the lunar module and talked to the ground command center. Soon, the lunar module was separated from the spacecraft and the spacecraft continued to fly around the moon. The lunar module began to land and slowly descended in an elliptical orbit.

He landed on the moon at 5: 00 a.m. on July 2 1 7: 40.
