Second Lesson
1. Teaching Objectives
1. Using the text language materials, understand how the astronauts flew to the moon and the development of modern aerospace industry , stimulate the interest in science and exploring the mysteries of the universe.
2. Able to read texts correctly, fluently and emotionally.
2. Teaching is important and difficult
Focus: Understand the process of astronauts flying to the moon.
Difficulty: Understand the great significance of the moon landing and stimulate interest in exploring the universe.
3. Teaching process
(1) Introduction
1. Teacher: July 16, 1969, this is a great day, Apollo 11 The U.S. spacecraft carried three astronauts out of the earth and onto the moon. American astronaut Armstrong was the first to set foot on the moon, which humans have dreamed of for thousands of years. Let us relive this exciting moment. scene.
(Courseware demonstrates the live moon landing)
2. Teacher: After watching this short video, what do you want to say the most? You can use sentences from the text.
(Mankind finally realized the dream of landing on the moon and took the first step into space)
(2) Continue to study the second part of the text
1. Students study the second part of the text independently. Find the sentences that interest you most, draw them, read them, and tell your classmates what you think.
2. Students learn independently
3. Discussion and communication.
It breaks away from the gravity of the earth and causes weightlessness.
●Read the sentences describing weightlessness in the text
?The astronaut felt that his body was light and he could not stand firm in the cockpit. He would jump up if he lifted his feet a little. Three or four meters high. ?
?They are floating around in the cockpit
Catch the words "light, unable to stand, momentarily, floating around" to let students experience the feeling of weightlessness. Feel and guide reading.
●How to sleep:
? There is no distinction between up, down, left, right and front and back in the cockpit, so they can sleep floating in the air, or sleep hanging with their heads up and their feet down. ?
●How to eat.
The food they eat is specially made. When eating, first put the food into a plastic bag, then fill it with water, knead the food into a paste, and then squeeze the food into your mouth like toothpaste. If you are eating hard granular foods such as peanuts, let them float in the air and then catch them in the air like fish looking for food. ?
Here is how the astronauts eat after losing weight. The author uses some words to express order, can you find it?
(? First? Then? Then? indicates the order in which astronauts eat)
In order to make it clear about aerospace How do astronauts eat hard pellet food? What sentence is used in the text to explain?
(Use "like a fish looking for food" to compare the way astronauts eat hard pellet food) Experience the feeling , guide reading.
●See the scene of the universe in the spacecraft:
The moon: As the angle of the light changes, it displays strange colors. (Gray, brown, yellow?)
Earth: blue and white light
(3) Study Part 3
1. Transition: Passage After more than three days of flight, humans are getting closer and closer to the moon of their dreams. Is the process of astronauts landing on the moon as easy as we imagined?
Students read the third part by themselves and look for words that indicate that this process is not easy.

2. Teacher: It was 22:56:20, US time, on July 20, 1969. After a long period of preparation, Armstrong slowly came down the escalator. . The teacher learned from the information that the hanging ladder had nine steps, but it took Armstrong three full minutes to reach the moon, one step at a time. At this time? (Human beings finally landed on the moon, which they have been fascinated by for thousands of years.)
3. Teacher: Let us take a look at this great moment and remember this great moment.
(Courseware demonstration: At 22:56:20 on July 20, 1969, the first human footprints were finally made on the moon)
Teacher: Facing the long-sleeping The moon, what do you think the astronauts want to say most at this moment?
(Thousands of years of dreams have finally come true, and we have finally landed on the moon that we have longed for)
Teacher : Armstrong once said this after landing on the moon: "This is a small step for me, but a giant step for mankind." ?
(Courseware demonstration: This is a small step for me, but a giant step for mankind!? Armstrong)
Teacher: Read this sentence for yourself, Think about what Armstrong’s sentence means?
Students free reading
Teacher: What a meaningful sentence! Can you understand its meaning?
(For a person, it is a small step from the ladder to the moon, but for science~~)
(This moon landing plan embodies the efforts of many people, and many scientists are How many days and nights have been devoted to this~~)
(This small step spans five thousand years)
Teacher: Who can read this sentence well? Name it
Teacher: ? Small step?, ? Big step? What a huge contrast! Who can read it again? Read by name
Read together
4. Armstrong is the first man to land on the moon. How is he feeling at this moment? (In addition to happiness, he is also excited and proud) Please read this sentence with pride again. (Human beings finally landed on the moon, which they have been fascinated by for thousands of years.)
(4) Study the 7th natural paragraph
Transition: So what is the real situation on the moon? ?Invite students to read the seventh natural paragraph of the text together.
1. Read paragraph 7 together.
2. Complete the fill-in-the-blank question
Based on this passage, students should try to complete the following fill-in-the-blank question. As long as you can fill in the blank, it means you have understood it.
On the moon there is neither , nor , only . Scientists analyzed and studied the materials collected from the moon and drew conclusions.
(Fill in the blanks and read together)
Four. Summary, sublimation, expansion and extension
1. (Supplementary writing on the blackboard): This trip to the moon is Humankind's (dream) for thousands of years has finally (realized) today. What power was used to realize this? (Science)
2. Armstrong was the first man to land on the moon, and No one from China has landed on the moon yet. On October 15, 2003, astronaut Yang Liwei flew into space on Shenzhou 5 and circled the earth 14 times, becoming the first Chinese person to fly into space. With the successful launch of Shenzhou-6 and Shenzhou-7 manned spacecraft, six astronauts from our country have now flown into space.
3. Students, the moon is there, and it will never stop us from exploring. Do you want to make the moon serve us through your own research and design? There are countless numbers hidden in the endless universe. The teacher hopes you will study hard about the unclear mysteries, study them and develop them in the future, so that more resources can benefit mankind.
5. Assign homework
1. Read the text thoroughly
2. Collect information after class and write a blackboard report with the title "Magical Universe" .
