2. Do and did and other auxiliary verbs

What is the present simple of the verb to like? Sometimes it is

I do like 

You do like etc

We do this when we want to be more emphatic. See this example:

Do you enjoy your job?

I  enjoy my job [no emphasis]

I do enjoy my job [emphasis – you’re now going to say exactly why]

We can do this with almost any auxiliary verb in English. But to make it work you need to be able to use short forms too. See this

I’ve been to the USA [short form showing no emphasis – the way we normally speak]

I have been to the USA [stressed long form – unusual to show special emphasis]

Pronunciation again

Just as before it helps to use your voice to stress the words in bold – this time it’s the auxiliary verbs.
