Explanation:
The text has different tenses:
- Present perfect simple: it is in the first, third, and sixth points.
We use present perfect to talk about activities in the recent past, like in the first and sixth case where the word "just" and "yet" indicates these recent past events or activities. We also use it to talk about experiences, like point three, where we ask Paul about Prague. The word ever indicates this tense use since we can only use it in interrogative and negative questions in the present perfect.
- Present continuous: point two is telling us what the person is feeling at the moment. In point seven, the present continuous tells us about an activity taking place in the present. In point eight, we use the present continuous tense since it talks about a plan in the future that has already been planed.
- Present simple: Is present in point four to talk about Paul's routine at work. In point nine, we use the present simple tense to talk about a habit, which in this case is something that he says regularly. Lastly, it is in point ten to indicate plans that have a date or time set.
- Present perfect continuous: is in point five, and we use it to talk about activities that started a short while ago and that are still happening. We do not use the present perfect simple tense because it would indicate that the activity started not in the recent past.
