Margot Politis. Welcome to Study English, IELTS preparation.
Today we have an environmental theme on Study English, but it's an environmental story with
We find out about a new toilet system that has been developed to save the local environment
in a Tasmanian park.
We're going to be looking at how to talk about processes, so listen carefully to David Holman
talk about his new environmentally friendly toilet.
The liquid waste comes from the toilet behind me. There's a containment vessel for the solids.
From the bottom of the solids you drain off the liquid and it comes down here down this
OK. The pipe tips into this tipping bucket arrangement and what this does is it fills
up to a point, and then it suddenly tips and that will measure each time it tips. So we
can calculate the amount of liquid effluent that's gone in.
As that fills up, you can see the towelling material here will come in contact with the
effluent, the air is drawn in through these holes and will actually direct the air in
onto the surface of the water, through the wick and out through the top.
OK, so David was talking about how his toilet, the Enviro-Loo, works.
He was describing a process. Today we're going to look at the type of language you'll need
to describe processes.
We'll listen to David again. This time, listen out for the types of verbs he uses.
