Callum: Hello and welcome to 6 Minute English, I'm Callum Robertson and joining me today is Kate, hello Kate.

Kate: Hello Callum.

Callum: Now Kate, something which we both have in common is that we are both Scottish, though you couldn't tell from my accent and today's programme is all about what is perhaps the most famous mystery associated with Scotland. What do you think that is?

Kate: Mmm, let me think. Is it perhaps Nessie? The Loch Ness Monster?

Callum: Yes, it is, indeed. What is Loch Ness, Kate?

Kate: Well Loch Ness is a lake, called Ness, Loch Ness. And loch is the Scottish word for lake.

Callum: We'll hear more about the loch and the monster shortly, but first, our question, which should be an easy one for you Kate, I think. Loch is the Scottish word for Lake, but what is the Scottish word 'dreich' used to describe: a: cold wet weather b: deep dark water c: deep soft snow

Kate: Ah, well I know this one. I love this word 'dreich'. It means a: cold wet weather.

Callum: We'll find out if you're right at the end of the programme. Now back to Loch Ness. Could you tell us a bit more about it?

Kate: Well Loch Ness is a very big loch; it's about 37 km long and holds the largest amount of water of any lake in UK. The water is very deep and very dark. And it's also known as the home of the Loch Ness Monster.

Callum: When did all this talk of a monster in the loch begin? Let's listen now to part of a report about new information which has been revealed regarding the monster. Listen out for this information. When did the legend start and when did it become world famous? Here's the BBC's Colin Blane:

Colin Blane

The legend of the Loch Ness Monster goes back more than a thousand years but the story attracted world-wide attention in the 1930s after a Scottish newspaper reported the beast had been seen crossing the road.

Task. Listen to the talk and mark the sentences True or False.
