Present Perfect to express “experience”. ESL: tenses – from pre-intermediate to advanced levels.
We use the present perfect to talk about experiences in the past up to the moment of speaking. The present perfect is “subject + auxiliary ‘have’ + past participle”. We often shorten ‘have/has’ to ”ve/’s’.
I’ve eaten in this restaurant many times.
To make the negative we add ‘not’ between the auxiliary ‘have’ and the past participle.
I haven’t had it before.
The question form is auxiliary ‘have/has’ + past participle.
