Hello. I'm

0:15

Margot Politis. Welcome to Study English, IELTS preparation.

0:19

Today we have an environmental theme on Study English, but it's an environmental story with

0:25

a difference.

0:26

We find out about a new toilet system that has been developed to save the local environment

0:32

in a Tasmanian park.

0:34

We're going to be looking at how to talk about processes, so listen carefully to David Holman

0:39

talk about his new environmentally friendly toilet.

0:44

The liquid waste comes from the toilet behind me. There's a containment vessel for the solids.

0:46

From the bottom of the solids you drain off the liquid and it comes down here down this

0:51

pipe.

0:51

OK. The pipe tips into this tipping bucket arrangement and what this does is it fills

0:58

up to a point, and then it suddenly tips and that will measure each time it tips. So we

1:03

can calculate the amount of liquid effluent that's gone in.

1:06

As that fills up, you can see the towelling material here will come in contact with the

1:12

effluent, the air is drawn in through these holes and will actually direct the air in

1:17

onto the surface of the water, through the wick and out through the top.

1:21

OK, so David was talking about how his toilet, the Enviro-Loo, works.

1:28

He was describing a process. Today we're going to look at the type of language you'll need

1:33

to describe processes.

1:36

We'll listen to David again. This time, listen out for the types of verbs he uses.

1:42

The liquid waste comes from the toilet behind me. There's a containment vessel for the solids.

1:47

From the bottom of the solids you drain off the liquid and it comes down here down this

1:49

pipe.

1:50

OK. The pipe tips into this tipping bucket arrangement and what this does is it fills

1:57

up to a point, and then it suddenly tips and that will measure each time it tips. So we

2:01

can calculate the amount of liquid effluent that's gone in.

2:06

David uses a variety of verbs and tenses. But mostly he uses the simple present tense.

2:14

The simple present is often used to describe processes and procedures.

2:19

Let's look at some examples.

2:22
