  • Hello. I'm

  • 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:

  • actually

  • in fact

  • certainly

  • of course

  • really and

  • surprisingly

  • Let's listen to a Wildlife Ranger, Greg Miles, answering a reporter's question. Listen for

  • attitude markers.

  • 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.

  • Greg Miles says: There has actually been quite a lot done in fact.

  • He uses the attitude markers, actually and in fact to show that he disagrees with the

  • reporter, and to advance his own view.

  • It's a polite way of expressing an opposing opinion.

  • Other examples of words and phrases that are used to do this include:

  • as a matter of fact

  • to tell the truth, or well

  • Let's see some examples.

  • Cane toads look harmless, but as a matter of fact, they're dangerous.

  • I thought you liked cane toads? Well, I don't.

  • Can you hear the attitude expressed in these phrases?

  • Now here's ecologist, James Smith again.

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

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

  • James uses actually here to introduce details. Because the details of the toxins are surprising

  • in nature, and perhaps unexpected, 'actually' provides this subtlety of meaning.

  • Now here's Greg Miles again. He uses two other attitude markers.

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

  • He says: apparently and certainly.

  • He says: the crocodile was apparently killed.

  • He uses apparently because he got his information from someone else, and he's not certain that

  • it's true. Based on appearances, it looks like the crocodile was killed by the cane

  • toad.

  • Greg says: certainly one death adder was found dead.

  • Here, Greg is emphasising that there's no doubt that this is true, that the death adder

  • was killed by the toxins in the cane toad.

  • From the use of these attitude markers, we can tell that he's not completely sure the

  • crocodile was killed by a cane toad, but he's definitely sure the death adder was killed

  • by one.

  • Okay. Let's turn our attention to another way you can express subtleties of meaning

  • in English.

  • They're corelative subordinating conjunctions.

  • The words themselves are short and simple:

  • so that and

  • such that

  • Listen to Greg Miles talking about the number of cane toads eating insects.

  • The flip side of that is that there's 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.

  • Greg says: Cane toads are so numerous that they suck up all the insects from the biota.

  • This means that cane toads are numerous enough to suck up all the insects from the biota.

  • There are enough of them to do that.

  • So that is called an amount construction. It expresses a meaning similar to enough,

  • which means an adequate number or amount.

  • But this construction also adds a meaning of result, using the 'that-clause'.

  • Let's study a sentence to see how this construction works.

  • Cane toads are numerous.

  • How numerous?

  • So numerous.

  • With what result?

  • That they suck up all the insects from the biota.

  • Cane toads are so numerous that they suck up all the insects from the biota.

  • The sentence uses the amount structure 'so that' to define an amount and a result.

  • Here's another example: Have you seen the film Cane Toads?

  • The film was so good that we went to see it twice.

  • So tells us how good the film was.

  • That tells us the result: We went to see it twice.

  • Let's listen to how Professor Madsen expresses amount in relation to cane toads.

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

  • will be millions of cane toads out there.

  • He uses another construction to express the amount. He says such:

  • Cane toads are such prolific breeders.

  • He adds the result clause there will be millions of them, but without using the word that.

  • 'That' is sometimes omitted in informal English. It is understood without being stated. More

  • formally he would have said:

  • Cane toads are such prolific breeders that there will be millions of them.

  • So and such in these constructions also provide emotive emphasis.

  • For example:

  • Cane toads are so ugly!

  • Cane toads are such a pest!

  • So today we've looked at attitude markers and language for expressing emotion.

  • We've also talked about the degree or amount constructions so and such.

  • Using these language features will make your language more interesting, and will show an

  • appreciation of subtleties of meaning.

  • And it's time for me to go, but you'll find today's story and a lot more on our Study

  • English website.

  • I'll see you next time. Bye bye.
