Exercise 7
Step 1
1 of 2
Sabrina and Grace are friends and roommates. One afternoon, Grace came home to loud music blasting out of Sabrina’s stereo.

Grace: Hey! Hey! Sabrina!

Sabrina: Oh! Hey, Grace!

Grace: Can you turn it down?

Sabrina: I’m sorry! What did you say?

Grace: I said can you turn the music down? It’s so loud. Turn it down before you go deaf!

Sabrina: Oh, wait. Sorry about that.

Grace: Finally! Thank you. It’s so loud. I almost thought I’m going to lose my hearing.

Sabrina: Really? It wasn’t that loud, at least for me.

Grace: You know, when it gets too loud, it can damage our hearing. I just had a class earlier and we discussed about noise-induced hearing loss. We have these sensitive structures in our ears, which can be quickly damaged if we are always exposed to loud and long-lasting sounds.

Sabrina: I didn’t know. I’m so glad that you have mentioned it. Moving forward, I’ll be more careful about the noises. Sorry! Let me make it up to you. Let’s grab some coffee, my treat!

Grace: Wow! That’s awesome. I’ll just grab my coat.
