|If you're ever fortunate enough to be addressed with the lesser spotted "how do you do?" or more commonly, "how's it going?", "what's up?" or "alright?", do you respond by telling the truth? If someone says "let's do lunch sometime" should you whip out your diary and tentatively pencil in a date? And why do the Brits say "sorry" when someone else bumps into them with their trolley in the supermarket? As language teachers one of our main aims is to equip learners with the tools to be effective communicators in English. In our quest, we often teach vocabulary and grammar as separate items, but this doesn't help our learners know that the response to "how do you do?" is "how do you do?". Knowing how to react to certain phrases, that is, functional language, in certain situations is key for effective communication to take place. In this practical session we'll explore functions of the language and how they can be taught in the classroom using examples from the new International Express. This session will give you several ideas to help you help your learners function in English.
