a. Let’s discuss the text “Making Echoes”. 1. How is an echo made? 2. What does the number of echoes depend on? 3. Which is the best place to hear echoes? 4. Why do we hear one sound after another? 5. Did you like the text? If yes, then why?

1. An echo is made when a sound hits a hard surface, reflects from it and comes back to us.

2. The number of echoes depends on the distance to reflecting surfaces and on how many surfaces reflect the sound.

3. Mountains, caves, cliffs and large empty buildings are good places to hear echoes.

4. We hear one sound after another because the reflected sounds travel different distances and return at different times.

5. Yes, I liked the text because it explains an everyday phenomenon in a clear and interesting way.
