Hello. I'm Margot Politis. Welcome to Study English IELTS preparation.
Today we're going to focus on word form groups - noun, verb and preposition phrases.
Then, we'll look at some words that can be used as both nouns and verbs, and we'll learn
how to tell which is which.
But first, we visit an automotive factory - a place where they build cars - and we see
how a new piece of machinery is helping to avoid mistakes in the manufacturing process.
Here, we have two faults, which are very common in the automotive industry, where the weld
has deviated from the seam here.
Paint and grease are very common faults in the automotive industry and where we've welded
over the paint, you can see that there's bubbles in the weld. Typically we call this porosity.

Understanding English is much easier if you understand how words can be grouped together.
Knowing the function of a group of words can help you to follow a sequence of ideas when
you're reading or listening.
The main word form groups are noun phrases, verb phrases and preposition phrases.
Let's begin with noun phrases.
A noun phrase is made up of a determiner.
That might be an article, like a, an or the.
A determiner could be a number, like one, two or three.
Or it could be a demonstrative adjective, for example this or those.
As well as a determiner, a noun phrase can have a modifier.
A modifier can be an adjective, like big, green or impressive.
Or it could be a possessive, like my or John's.
And finally, a noun phrase must have a noun.

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