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

0:18

Today on Study English, we're going to practise using the words 'some' and any'. We'll also

0:25

build up our vocabulary with some words about 'space' and 'astronomy'.

0:30

But first, we're going to meet a planetary geologist who is fascinated by the planet

0:36

Mars.

0:40

Mars is still a fascinating place. In the solar system, it's one of the most interesting

0:45

places where there may be life, apart from the Earth.

0:49

We want there to be Martians with spaceships, ET, flying saucers, UFOs. We want all of these

0:56

things.

0:58

It's frozen to a depth of about 7 kilometres at the equator, maybe 20 kilometres at the

1:06

pole caps, so there is a very thick, frozen layer on Mars. The people who talk about cold

1:16

the planet is.

1:17

These scientists are hoping to find out about life on Mars. They're looking closely at the

1:24

landscape, and similar landscapes, to try to understand everything they can about the

1:30

planet.

1:30

Listen to Dr Hoffman talking about how the landscape of Mars was formed. Pay special

1:38

attention to how he uses the words 'some' and 'any'.

1:43

Well, if we look at the picture here, cutting down through each of these gullies is a little

1:48

black channel that's bulldozed its way through the snow, carved its way down and pushed the

1:53

snow aside and each springtime, part of the snow collapses as it warms in the sun. It

2:00

doesn't go through a liquid phase, it goes directly from solid to vapour, boils away,

2:04

and falls down the slope and then you have this tumbling mass, a little avalanche of

2:09

some snow, some rock, some sand, some dust, all churning up together.

2:15

What I have shown with this work is that the structures that we see in Antarctica are a

2:21

good place for life to be, if there is life on Mars. It would be very primitive microbes.

2:26

There wouldn't be any sort of multi-cellular life there.

2:32

In English, we use the words 'some' and 'any' to talk about 'how much' or 'how many' of

2:39

something.

2:41

'Some' and 'any' are called determiners.

2:45

They tell us something about the quantity or amount we're discussing.

2:49

Listen to how Dr Hoffman uses the word 'some'.

2:55

It doesn't go through a liquid phase, it goes directly from solid to vapour, boils away,

2:59

and falls down the slope and then you have this tumbling mass, a little avalanche of

3:04

some snow, some rock, some sand, some dust all churning up together.

3:10

He says 'some sand, some dust'.

3:14

The word 'some' suggests an indefinite number or amount. It's not specific.

3:22

We use it when it isn't important exactly how much or how many we mean.

3:28

So, you might say:

3:30

I'd like some milk.

3:32

Or:

3:33

Would you like some tea?

3:36

'Some' is usually used in affirmative clauses, like this:

3:41

There are some letters for you at the post office.

3:46

And we also use 'some' in questions that expect a 'yes' answer.

3:51

For example:

3:52

Would you like some help? Yes please.

3:55
