Ex.4. Read the following dialogue and invert your own: - You see, I’m a bit confused. I thought Britain, Great Britain and the British Isles mean the same. Am I right?
- Well, in everyday speech Britain, Great Britain and the British Isles are used to mean the same country, but it is not quite correct.
- Can you explain why Britain is called Great Britain?
- In fact, it is only one of about 5500 British Isles. It is the biggest one. That is why it’s called Great, because of its size.
- I see. Does it also mean the United Kingdom, then?
- No, it consists only of the country’s three parts. The fourth part, Northern Ireland, is on the next largest island – Ireland.
