We use present perfect simple when we talk about a period that continues until now with trigger words such as – recently, in the last few days, since, for a long time, etc.

1. I’ve met a lot of people in the last few days.
2. Have you heard anything from Ben recently?
3. Everything is going well. There haven’t been any problems so far.
4. The weather is bad here. It’s (= It has) rained every day since I arrived. (= from when I arrived until now)
5. It’s good to see you again. We haven’t seen each other for a long time.

In the same way, we use present perfect simple with today, this evening, this year, etc. when these periods are not finished at the time of speaking:

1. I’ve drunk four cups of coffee today.
2. Have you had a holiday this year?
3. I haven’t seen Tom this morning. Have you?

We sue present perfect simple when we are giving news:

1. I can’t go skiing because I have broken my leg.
2. I’ve bought a new house
3. At last! I’ve finished the project!
