Margot Politis. Welcome to Study English, IELTS preparation.
Today, we're going to talk about expressing attitude, and using the words so and such.
And we're going to find out about some nasty creatures called cane toads, and all the trouble
they can cause.
Curious? Let's watch the clip.
You can see these large glands he's got behind his eyes, which contain a lot of toxin. It's
got various compounds in there but basically what it does is give you a heart attack. The
toxin's actually all throughout the skin but the main concentration is in these glands.
So basically, something bites it, if it gets into its bloodstream, there's a good chance
it will be killed very quickly.
We found a dead freshwater crocodile, which was apparently killed. Certainly a one death
adder, which is a venomous snake, quite an important Australian snake, we found one of
those freshly dead with a small toad in its mouth. And even to small children, if a child
was to put them in their mouth, the toxin is quite severe.
The flip side of that is that there are a whole lot of animals which will be out-competed
by cane toads. So they're other animals, which eat insects for instance, 'cause cane toads
are so numerous that they suck up all the insects from the biota, like big vacuum cleaners
and so they can actually cause other animals to starve.
Why are we literally sitting back and watching the cane toad invasion move further and further
up through Kakadu and through the Northern Territory?
Well there has actually been quite a lot done, in fact, over a period of perhaps 10 years
prior to this, a huge amount of effort and money has already been spent on looking at
some way and means of controlling cane toads. All that work has come to nothing, and most
people understand that now.
What we have to do is wait on the big guns in Canberra with their genetic engineering
and biological control work. That's the only hope there is.
Cane toads are such prolific breeders, each female would produce 50 thousand eggs. There
will be millions of cane toads out there.
Unfortunately, cane toads are a big environmental problem in Australia. They're a species that
was introduced from another country. We'll use their story to talk about attitude or,
more specifically, attitude markers.
Attitude markers can indicate the attitude of someone to what they are saying or what
others have said.
I just used one. I said: Unfortunately', cane toads are a big environmental problem.
The word unfortunately indicates my attitude to cane toads.
Other words that are attitude markers include:
