Hello. I'm Margot Politis. Welcome to Study English IELTS preparation.

0:18

Today we're going to focus on word form groups - noun, verb and preposition phrases.

0:26

Then, we'll look at some words that can be used as both nouns and verbs, and we'll learn

0:31

how to tell which is which.

0:33

But first, we visit an automotive factory - a place where they build cars - and we see

0:39

how a new piece of machinery is helping to avoid mistakes in the manufacturing process.

0:48

Here, we have two faults, which are very common in the automotive industry, where the weld

0:52

has deviated from the seam here.

0:55

Paint and grease are very common faults in the automotive industry and where we've welded

1:01

over the paint, you can see that there's bubbles in the weld. Typically we call this porosity.

1:07

At the moment, you only take a sample of the cars. You're not able to test every weld in

1:12

every car, and that's a major advantage of our technology. We can test every weld in

1:16

every car.

1:19

Understanding English is much easier if you understand how words can be grouped together.

1:26

Knowing the function of a group of words can help you to follow a sequence of ideas when

1:32

you're reading or listening.

1:34

The main word form groups are noun phrases, verb phrases and preposition phrases.

1:45

Let's begin with noun phrases.

1:48

A noun phrase is made up of a determiner.

1:53

That might be an article, like a, an or the.

1:59

A determiner could be a number, like one, two or three.

2:07

Or it could be a demonstrative adjective, for example this or those.

2:15

As well as a determiner, a noun phrase can have a modifier.

2:21

A modifier can be an adjective, like big, green or impressive.

2:28

Or it could be a possessive, like my or John's.

2:34

And finally, a noun phrase must have a noun.

2:39

An example of a noun phrase is the IELTS test.

2:44

It has a determiner, a modifier and a noun.

2:54

Now, let's take a look at a verb phrase.

2:57

There are a variety of verb phrases.

2:59

The simplest verb phrase is a single main verb standing alone.

3:06

Other verb phrases are formed by an auxiliary verb + main verb or different combinations

3:13

of auxiliary verbs + main verbs.

3:17

For example:

3:19

She finished her homework.

3:22

She had finished her homework.

3:26

She was required to finish her homework.

3:30

She finished doing her homework.

3:33

OK. So that's noun phrases and verb phrases. There are also preposition phrases.

3:41

A preposition phrase begins with a preposition. It could be a preposition of time, place or

3:50

direction.

3:52

So a preposition phrase starts with words such as at, on, during, up or down.

4:01

Let's put a noun, verb and preposition phrase together.

4:06

In the sentence: The IELTS test finished at one o'clock on Friday.

4:13

we have a noun phrase, a verb phrase, and a preposition phrase.

4:24

The function of verb, noun and preposition phrases depends on their position in the sentence.
