Answers to the exercises:
Exercise 1: Check your answers from Before You Watch.
□ airplane butterfly □ city computer
diver frog □ horse polar bear
□ ship submarine volcano whale
Exercise 2: Complete these quotes with the words you hear in the video.
1) Emily Ainsworth: “It’s part of human nature to be curious and to want to learn more about the world.
2) Juan Martinez: “It’s where you find yourself, where you find new things, where you grow.”
3) Lee Berger: “We think we know this place, but we don’t. We think we know ourselves, but we don’t. We think we understand how things work, but we don’t.”
4) Catherine Workman: “By knowing what’s out there, we care about what’s out there.”
5) Cory Richards: “And if we have more to care about, then we engage more fully with our world and more fully with our human family, and we act—you know—with love.”
Why is it important to explore?
To satisfy curiosity and learn more about the world, know about ourselves and new things, help us grow, keep life exciting, challenge ourselves, know about the place, ourselves and how things work, know and care, and engage and act with love.
Exercise 3:
1) a first flight—D butterfly with a tag
2) used to explore an inaccessible place—E drone
3) a new species—B frog
4) eight new species—A fish
5) a natural alarm clock—C polar bear
2. Watch the short video again to understand it better. And then reconstruct the text by summarizing the main content of the video.
Activity 4 Post-viewing
Discuss the following questions in groups and share answers.
Suggested answers:
1. Of the explorations in the video, which seems the most important? Which seems the most interesting? Why?
The most important is the one with the butterflies, because butterflies are easily affected by climate and pollution, and so their lives can tell us a lot about how the world is doing.
The most interesting is the cave diving where they found the animal bones. It Just seems so strange and mysterious, and one would not expect to find bones there.
2. Why is it important to explore, in your opinion?
I think it is important to explore because exploration is a part of human growth, both as an individual and society. Through exploration, we develop ourselves. Our interests and curiosity cause us to learn, to improve, and to be better.
3. How would you like to explore our world? Why?
I would like to visit places with my camera and take photos of interesting places and people, as I enjoy photography and love travelling and finding out about new cultures.
