Grammar explanation
We use the present perfect simple (have or has + past participle) to talk about past actions or states which are still connected to the present.
Unfinished time and states
We often use the present perfect to say what we've done in an unfinished time period, such as today, this week, this year, etc., and with expressions such as so far, until now, before, etc.
They've been on holiday twice this year.
We haven't had a lot of positive feedback so far.
I'm sure I've seen that film before.
We also use it to talk about life experiences, as our life is also an unfinished time period. We often use never in negative sentences and ever in questions.
I've worked for six different companies.
He's never won a gold medal.
Have you ever been to Australia?
We also use the present perfect to talk about unfinished states, especially with for, since and how long.
She's wanted to be a police officer since she was a child.
I haven't known him for very long.
How long have you had that phone?
Finished time and states
If we say when something happened, or we feel that that part of our life is finished, we use the past simple.
We visited Russia for the first time in 1992.
I went to three different primary schools.
Before she retired, she worked in several different countries.
We also use the past simple for finished states.
We knew all our neighbours when we were children.
I didn't like bananas for a really long time. Now I love them!
Past actions with a result in the present
We can use the present perfect to talk about a past action that has a result in the present.
He's broken his leg so he can't go on holiday.
There's been an accident on the main road, so let's take a different route.
They haven't called me, so I don't think they need me today.
Again, if we say when it happened, we use the past simple.
He broke his leg last week so he can't go on holiday.
However, we often use the present perfect with words like just, recently, already, yet and still.
We've recently started going to the gym.
She's already finished season one and now she's watching season two.

Hello again Gloria,
The first thing to note is that the difference here is very nuanced and not one which is a hard and fast rule.
An intermittent action here is one which occurs many times over a given period of time. This contrasts with an action which is constant and unbroken. In other words, if I do something for three hours then it suggests I spent the whole time on the task. If I do something over three hours it suggests I did in in that time, but may have taken breaks or done it in a series of repeated efforts. That is why over seems slightly more appropriate to me in your example, but either would be perfectly fine.
As I said, the difference is very slight and in most cases both can be used.

Hello Hamdy Ali,
I'm afraid we don't provide answers to these kinds of questions. We're happy to help users with their English through explanations are clarifications, but we don't provide answers to tasks from elsewhere. If we did so, we'd end up doing users' homework and tests for them!

Hello Kim Hui-jeong,
Yes, both sentences are correct. The present perfect is possible in the second sentence because even though Mozart is dead, his music can still influence people today. Well done!

Hello brian1010,
It would depend on the actual situation described here (that is, how long this reform has been in place), but it sounds to me as if there would be little if any difference in meaning between the present continuous and present perfect continuous here. The latter form would emphasise the fact that the lack of funding began in the past, but the present continuous also suggests this. This is why I'd say there's little difference in this specific case.
This is not always the case, though. Hope this helps you make more sense of this.
All the best,

Hello brain1010,
If you say 'has kept', it communicates much the same idea and speaks about a situation up until the moment of speaking. 'is keeping' and 'has been keeping' suggest that the situation may change, whereas 'has kept' doesn't express this idea as much (though neither does it exclude the possibility).
If you have any further questions about this, could you please provide more context? What exactly tenses mean is highly contextual and so it's difficult to say for sure without knowing more.
All the best,
Kirk
