Hello. I'm

0:14

Margot Politis. Welcome to Study English, IELTS preparation.

0:18

Today, we're going to talk about expressing attitude, and using the words so and such.

0:26

And we're going to find out about some nasty creatures called cane toads, and all the trouble

0:31

they can cause.

0:33

Curious? Let's watch the clip.

0:34

You can see these large glands he's got behind his eyes, which contain a lot of toxin. It's

0:42

got various compounds in there but basically what it does is give you a heart attack. The

0:45

toxin's actually all throughout the skin but the main concentration is in these glands.

0:49

So basically, something bites it, if it gets into its bloodstream, there's a good chance

0:53

it will be killed very quickly.

0:55

We found a dead freshwater crocodile, which was apparently killed. Certainly a one death

1:00

adder, which is a venomous snake, quite an important Australian snake, we found one of

1:03

those freshly dead with a small toad in its mouth. And even to small children, if a child

1:08

was to put them in their mouth, the toxin is quite severe.

1:12

The flip side of that is that there are a whole lot of animals which will be out-competed

1:15

by cane toads. So they're other animals, which eat insects for instance, 'cause cane toads

1:20

are so numerous that they suck up all the insects from the biota, like big vacuum cleaners

1:25

and so they can actually cause other animals to starve.

1:27

Why are we literally sitting back and watching the cane toad invasion move further and further

1:34

up through Kakadu and through the Northern Territory?

1:35

Well there has actually been quite a lot done, in fact, over a period of perhaps 10 years

1:39

prior to this, a huge amount of effort and money has already been spent on looking at

1:43

some way and means of controlling cane toads. All that work has come to nothing, and most

1:48

people understand that now.

1:49

What we have to do is wait on the big guns in Canberra with their genetic engineering

1:54

and biological control work. That's the only hope there is.

1:58

Cane toads are such prolific breeders, each female would produce 50 thousand eggs. There

2:04

will be millions of cane toads out there.

2:09

Unfortunately, cane toads are a big environmental problem in Australia. They're a species that

2:15

was introduced from another country. We'll use their story to talk about attitude or,

2:21

more specifically, attitude markers.

2:25

Attitude markers can indicate the attitude of someone to what they are saying or what

2:31

others have said.

2:33

I just used one. I said: Unfortunately', cane toads are a big environmental problem.

2:39

The word unfortunately indicates my attitude to cane toads.

2:45

Other words that are attitude markers include:

2:49

actually

2:50

in fact

2:51
