Hello. Welcome to Study English, IELTS preparation. I'm Margot Politis.
0:19
We're going to look at articles today - indefinite articles 'a' and 'an', and the definite article,
0:27
'the'.
0:29
But first, let's meet an oceanographer. She's talking about using underwater devices to
0:35
predict weather patterns.
0:37
See if you can hear her using articles while she talks about monsoons.
0:42
The monsoon gets a lot of its energy from the equatorial and sub-tropical Indian Oceans.
0:47
Dr Susan Wijffels, an oceanographer from Australia's CSIRO, is hoping that by measuring the state
0:53
of the Indian Ocean in those areas, scientists will be able to learn something about monsoon
0:57
predictability.
0:59
Predicting the monsoon is a very difficult thing and yet it impacts on millions and millions
1:04
of people, and so we think that, if we can predict the monsoon usefully, we can make
1:09
a real difference.
1:10
We know from El Nino that it's a fully global system, so you just can't study one small
1:16
part of the ocean and solve these problems. You really need a global integrated observing
1:20
system, and the Argo program is the first real big ocean attempt to do that, and it's
1:27
the float technology that's allowed us to even think about doing this.
1:30
Using articles before nouns is one of the most difficult things in learning English.
1:36
You can choose between indefinite articles 'a' and 'an', the definite article 'the',
1:43
or no article at all.
1:46
Let's start with the indefinite articles 'a' and 'an'.
1:51
The rule is that 'a' is used before words starting with a consonant, and 'an' is used
1:58
before words starting with a vowel.
2:01
So we have a banana, but an apple.
2:07
There are a couple of exceptions to the rule. Where the consonant 'h' is not pronounced,
2:12
we use 'an'.
2:14
So we say a happy man, but an honest man. The 'h' is not pronounced, so honest sounds
2:23
like it starts with a vowel.
2:26
Where the vowel 'u' is pronounced like a 'y' sound, we use 'a'.
2:30
So we say an umbrella, but a user, because user sounds like it begins with a 'y'.
2:40
'A' and 'an' are only used with singular nouns. We use 'some' with plural nouns.
2:48
The indefinite articles 'a' or 'an' are used to refer to indefinite things, things that
2:55
aren't specific. You use them when you're referring to any member of a group of things.
3:01
The indefinite article does not refer to a particular thing, but one out of many possible
3:07
things.
3:08
If I say I would like a banana, I just want any banana, it doesn't matter which one.
3:16
Let's look at an example of indefinite articles from the clip.
3:19
Predicting the monsoon is a very difficult thing and yet it impacts on millions and millions
3:24
of people, and so we think that, if we can predict the monsoon usefully, we can make
3:28
a real difference.
3:30
She uses the indefinite article twice.
3:34
She says 'predicting the monsoon is a very difficult thing'. There are many things that
3:41
are difficult to do, and predicting the monsoon is just one of them.
3:47
Secondly she says 'we can make a real difference'. There are many differences that can be made
3:53
in the world, but she is just talking about one of them.
3:56
So when do we use the definite article 'the'?
4:06
Well, we use it when we're referring to definite, specific things. We also use 'the' when we're
4:13
talking about one particular member of a group.
4:17
Luckily there is only one form of the word 'the', and it can refer to both singular and
4:24
plural nouns.
4:25
We say the banana and the bananas.
4:29
There is a difference in pronunciation though, when 'the' comes before a vowel sound, we
4:36
say 'thee', the apples.
4:38
So 'thee' before vowel sounds, and 'thuh' before consonant sounds.
4:45
Let's look at the clip again. Listen for 'the'.
4:49
You really need a global integrated observing system, and the Argo program is the first
4:55
real big ocean attempt to do that, and it's the float technology that's allowed us to
5:00
even think about doing this.
5:02
She says 'the Argo program'. She uses 'the' because there is only one Argo program. It's
5:10
a unique, particular thing.
5:12
She also says 'the float technology'. She is talking about a particular type of float
5:19
technology, not just any float technology.
5:24
There was a third 'the'. She said 'the first real big ocean attempt'.
5:30
We use 'the' in front of first, second and so on, because they refer to something particular
5:36
or unique.
5:37
There can be only one first attempt.
5:41
In the same way we use 'the' in front of superlatives - the best example, the biggest banana and
5:49
so on - because there can only be one best, or biggest, of anything.
5:54
OK. So that's the major difference between definite and indefinite articles, but there
6:01
are other rules as well.
6:03
We use 'a' and 'an' with countable nouns, that is, if the noun can be counted.
6:10
I ate an apple. Apples can be counted.
6:15
We use 'the' with uncountable nouns, with things that you can't count.
6:21
I swam in the water. (Water cannot be counted.)
6:25
I drank the milk. (Milk cannot be counted.)
6:30
We also use 'a' with counting expressions like a bottle of, a cup of, a bit of.
6:37
Listen to this:
6:40
The monsoon gets a lot of its energy from the equatorial and sub-tropical Indian Ocean.
6:45
She says, "The monsoon gets a lot of its energy".
6:50
Look at the monsoon, and the Indian Ocean.
6:54
These are both examples of other rules for 'the'.
6:58
We can use 'the' to describe 'generic nouns'.
7:02
A generic noun is a noun that describes a category or type of thing. It can often be
7:09
the same as using a plural noun.
7:12
So sometimes the monsoon means the same as monsoons. She's talking about monsoons in
7:19
general.
7:20
Predicting the monsoon is a very difficult thing and yet it impacts on millions and millions
7:26
of people, and so we think that, if we can predict the monsoon usefully, we can make
7:31
a real difference.
7:32
We know from El Nino that it's a fully global system, so you just can't study one small
7:37
part of the ocean and solve these problems. You really need a global integrated observing
7:40
system, and the Argo program is the first real big ocean attempt to do that, and it's
7:40
the float technology that's allowed us to even think about doing this.
7:40
And here's another rule. We also use 'the' with oceans, seas, rivers and deserts.
7:47
We say the Indian Ocean, the Yangtze River, the Gobi Desert.
7:54
We also use 'the' for points on the globe - the Equator,
7:59
the Tropic of Capricorn, the North Pole.
8:03
Choosing the right article can be very confusing, but if you follow the general rule that you
8:09
use 'the', the definite article, to refer to a particular thing or things, and 'a' and
8:16
'an', indefinite articles, to refer to one of a number of things, you shouldn't go too
8:22
wrong.
8:22
OK, so now we've seen how to use definite and indefinite articles, but sometimes we
8:33
don't use articles at all before nouns.
8:36
Let's look at when to use no article.
8:39
We've already seen that you can leave the article out when talking about plural generic
8:44
nouns.
8:46
Monsoons are unpredictable.
8:48
But this is true for uncountable generic nouns too.
8:53
Coffee is delicious.
8:55
Happiness is hard to find.
8:58
"Balls are round."
8:59
OK, so let's look at some sentences.
9:04
I would like a cake. (I would like one cake, any cake.)
9:09
I would like the cake. (I would like that particular cake.)
9:15
I like cakes. (I like all cakes.)
9:19
Here, cakes with no article is generic. It refers to cakes in general, all cakes.
9:27
Well that's all for today. Don't forget to practice those articles!
9:31
I'll see you next time for Study English. Bye Bye.
