Lesson 3 Section A
(3a-3c)
Learning Objectives
In this lesson you will:
1.read an interview about space exploration to extract key information and complete a mind map.
2. identify how a host uses questions and comments to keep an interview flowing.
3.understand the reasons for space exploration, broadening the view of scientific development.
Look and Say
Do you know the following things in China’s space exploration
Milestones of China's Space Exploration
In 1970,China launched its first satellite Dongfanghong-1.
China became the fifth country to send a satellite into space.
In 2003, Shenzhou-5 carried Yang Liwei into space. China became the third country with independent manned spaceflight.
In 2013, Chang’e-3 landed on the moon with the rover Yutu.
China became the third country to soft-land on the moon.
In 2019, Chang’e-4 made the first soft landing on the far side of the moon in human history.
In 2020, Chang’e-5 brought moon samples back to Earth.
China became the third country to achieve lunar sample return.
In 2021, Tianwen-1 landed on Mars with the rover Zhurong.
China successfully explored Mars for the first time.
In 2022, China’s Tiangong Space Station was fully built and began long-term crewed operation.
Why do we spend so much money and effort to explore space
Brainstorm
To learn about the universe
To find new resources
To develop new technology
To answer big questions (Are we alone )
To inspire people
...
Read the interview quickly and find out the three reasons mentioned in it.
First, to improve our knowledge of Earth and its place in the universe.
Second, technology developed for space can benefit us here
on Earth.
The third reason is that we may find new resources in outer space.
3a
Host: Our question today is: Why do we explore space Let's talk
to space scientist Dr Yang. Welcome, Dr Yang!
Dr Yang: Thank you very much. Well, there are three good reasons to
explore space. First, to improve our knowledge of Earth and
its place in the universe.
Host: Could you explain that a bit more
Dr Yang: Sure. The study of other planets helps us better understand
Earth's geology, history, and relationship with other planets.
Host: Oh, right.
Dr Yang: Second, technology developed for space can benefit us here
on Earth.
Read the interview and complete the mind map.
Host: Could you give our listeners an example
Dr Yang: Of course. Some satellites, for example, help us deal
with problems caused by climate change.
Host: Yes, that's very useful. And the third reason
Dr Yang: Well, at some point in the far future, we may find new
resources in outer space. It might sound crazy, but our
Earth may run out of resources. In that case, a new
home for us human beings will be needed.
Host: Wow, interesting! Maybe Mars will be made into our
new home in the future.
better understand
Earth’s geology, history, and relationship with other planets.
benefit us here
on Earth.
find new
resources in outer space
How do you understand these three reasons Try to explain in your own words or with some examples.
Discuss
Why can the study of other planets help us better understand Earth
e.g. The Moon has many craters. Earth has fewer because wind and rain slowly remove them. By comparing the Moon and Earth, scientists understand how Earth’s surface changes over time.
陨石坑
e.g. Scientists found evidence that Mars once had rivers and lakes. This helps us think about where water came from on Earth and how life might have started.
Could you think of more examples for the second reason
Astronauts lose muscle and bone in zero gravity. So scientists made special exercise machines for them. Now those machines are used in hospitals and gyms to help people recover from injuries.
Do you think humans will ever live on another planet
Why or why not
e.g. Mars is the most likely planet for a new home. It has days like Earth, some water, and a thin atmosphere. Scientists are already testing how to live there.
Listen to the interview. Pay attention to how the host keeps the interview going with questions and comments. Then role-play the interview.
3b
Ask for more explanation.
Show interest / comment.
Ask for an example.
Work with a partner to discuss your reasons for space exploration.
3c
In my opinion, the most important reason is ...
I think ... because ...
For example, ...
I agree with you. / That's a good point.
I see your point, but I also think ...
I'm not sure about that because ...
Could you explain that a bit more
Can you give an example
Language Points
1. The study of other planets helps us better understand Earth’s geology, history, and relationship with other planets.
geology n.地质；地质学 为不可数名词，指“地质学”这一学科，或某一地区的“地质特征”。

3.It might sound crazy, but our Earth may run out of resources.
crazy adj. 疯狂的；不理智的
常见搭配:
