Hello. I'm
0:14
Margot Politis. Welcome to Study English, IELTS preparation.

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?
