The reason I decided to write the book was to highlight important information about communication and the language functions you will use to communicate effectively. Some people are a little confused when I say 'language function' so I'll just quickly explain here:
Grammar - these are the correct verb tenses, noun forms and adjective order rules which are the building blocks of the language. For example, the Present Perfect, uncountable nouns etc.
Language functions (also called Functional Language) - this is what you do with the grammar you have learned. So, 'asking about the duration of an event' uses the Present Perfect tense (How long have you had the pain in your side?).
To communicate well, it's important to understand which functions to use in a given situation. This is more important than correct grammar. For example, if you say 'Can you explain me about the accident?', I will understand what you mean, even though 'explain me' is incorrect grammar. It should be Can you explain TO me....
The role play samples which I write and put on YouTube show you examples of some of the language functions you might use in similar situations. Remember that you should develop your own style, not just copy mine! I give you one or two examples under each function heading - you need to go away and think about the sorts of role plays you might have to do and think of the language you will use in them.
This is why I advise my students to write down some mini-dialogues covering particular functions. Think of how you will advise a patient about caring for a simple dressing at home. Try to have no more than 3 points you might tell the patient.
For example, 1. keep clean and dry 2. change every 2 days 3. tell your GP if you notice any discharge.
You might think of 3 different points ( cover dressing with a plastic before you have a shower, have a shower not a bath, have the stitches taken out after a week to ten days). It really doesn't matter what your points are. It's more important to think about the language you will use to advise - It's a good idea to.... You should....It's best to....Make sure that you..... Try not to.....
When you look at the videos on YouTube, try to identify the language I have used in them and think about the reasons I used those particular functions. Feel free to use them as a guide for your own dialogues but make sure your dialogues reflect your communication style, not mine!
