Hello, and welcome to Study English, IELTS Preparation. I'm Margot Politis.

0:17

Today we'll look at some strategies for meeting the requirements of vocabulary, one of the

0:23

criteria used to assess IELTS candidates.

0:26

When writing, you can expand what you want to say by adding words that give more detail,

0:33

or are more specific and descriptive.

0:35

This is a good way of showing the extent of your vocabulary.

0:41

Take this sentence for example:

0:44

Collection services can reduce rubbish.

0:48

What can you say to make this sentence more specific and descriptive?

0:52

First, look at 'collection services'. Ask yourself who, what, why and where?

1:03

What sort of collection services reduce rubbish?

1:06

They could be 'weekly collection services' or 'better collection services'. You could

1:15

also say 'more frequent collection services':

1:20

More frequent collection services can reduce rubbish.

1:26

You can do more than just use words in front of 'collection services'. You can also add

1:31

a phrase after it.

1:32

Ask yourself the same sort of questions: 'what is collected, who is collecting it'?

1:40

So you can add:

1:42

More frequent collection services for recyclables can reduce rubbish.

1:49

You don't have to stop at just one phrase. You might also want to say who does the collecting.

1:56

So:

1:57

More frequent collection services for recyclables by councils can reduce rubbish.

2:08

You can also add words to the verb in the sentence. We know more collection can reduce

2:14

rubbish - but by how much?

2:17

It can substantially reduce rubbish.

2:20

So:

2:22

More frequent collection services for recyclables by councils can substantially reduce rubbish.

2:32

Substantially is an adverb. It's one of the forms of the word substantial.

2:38

Adverbs often end with '-ly'

2:41

Other words that mean a large amount are vast, considerable and great.

2:50

Their adverbs are vastly, considerably and greatly.

2:58

Any of these words could be used instead of 'substantially'.

3:01

A good vocabulary is not simply the number of words you know. It's being able to use

3:10

all the forms of a word correctly.

3:13

For instance 'reduce' means to become smaller or to lessen. Listen to how it's used in this

3:20

clip from a story about sealing roads:

3:25

In Asia the cost of re-doing roads is very high. We can address that issue and give them

3:32

a tightly bound surface, which will reduce the costs for the regional councils.

3:38

Will reduce the costs. Reduce - that's the base form of the verb. Reduce is a regular

3:46

verb with the forms reducing and reduced. He uses one of these here:

3:54

Here you have a car that is travelling along an untreated section of road and then hitting

4:00

a treated section of the road. You can see that the dust is reduced by a significant

4:05

amount.

4:09

Is reduced by a significant amount. That's a verb form. But what form of reduce would

4:15

you use as an adjective?

4:19

Our product very effectively binds the soils and particles that make up the materials for

4:24

the roads. This means you can have a reduced cost in terms of the number of times that

4:29

road authorities have to maintain and repair that road over a long period of time.

4:34

A reduced cost. The -ed form can also be used as an adjective like this.

4:44

reduced price reduced pressure

4:49
