Question
Choose the correct alternative.
Answer
We use the Present perfect for experiences from the past up to present.
To form the Present perfect we use the Present simple of have + Past participle of the main verb.
The Past participle can be regular or irregular.
In questions, the subject goes after the verb to have.
