00:00The present perfect continuous and the present perfect progressive are exactly the same.
00:10Just two different words that mean the same.
00:13Now you need the auxiliary verb have.
00:16So let's go with this.
00:18Very simple.
00:19Don't forget has, he has, she has, it has.
00:22And you also need been.
00:25Been is the verb to be at the past participle.
00:30So be was been, the third one.
00:33And you also need the progressive form.
00:36So you need the ing verb.
00:38This is actually the present participle, but you don't need to remember that.
00:43So the present perfect continuous would be, I have been studying.
00:48You have been studying.
00:49He has been studying.
00:52The present perfect continuous has three main uses.
00:57Here they are.
00:59Okay.
00:59Actions started in the past that continue to the present.
01:03Actions that have just stopped.
01:05And temporary actions.
01:07Let's take a look at the first one.
01:09So the main use of the present perfect continuous is when we have an action that started in the past
01:18and it continues in the present.
01:21For example, I have been saving money for my trip around the world.
01:26I have been saving.
01:28So it's an ongoing situation.
01:31It's an ongoing action.
01:33I started saving in the past and I am still saving right now.
01:38So that's why we use the ing because it's still happening right now.
01:44Here's another example.
01:46The company has been investing in research and development.
01:50The company started investing many years ago in the past and it continued to invest until right now.
02:00The company is still investing now.
02:03So the company has been investing.
02:06Number two, actions that have just stopped.
02:10But watch out, there is a visible result in the present.
02:15So this one is interesting.
02:17You look at the picture and you see this girl.
02:20She looks tired and she looks terrible.
02:24So, hey, you look terrible.
02:27Have you been drinking?
02:29Have you been drinking?
02:31So you started drinking in the past and you have just stopped.
02:36And now I can see your face.
02:38I can see your eyes.
02:39I can see your hair.
02:41And I'm like, whoa, I think she has been drinking.
02:46Another example.
02:48You have flour all over your face.
02:51Ah, sorry, I've been baking.
02:53So the baking event or the baking action has just finished and now you can still see the result in
03:02the present.
03:04Temporary actions or situations.
03:07My car is being fixed.
03:09So I've been biking to work for the past few days.
03:13For the past few days.
03:15So it's an ongoing event.
03:18It started in the past and it's still happening today because my car has not been fixed yet.
03:24But it is only temporary because eventually I will get my car back.
03:30My car will get fixed and then I will drive to work instead of biking to work.
03:37Last example.
03:39I have been working late to meet the project deadline.
03:43But next week I'll be back to my normal 9 to 5 schedule.
03:49So once again, he has been working late.
03:53It's a temporary situation only to meet the deadline.
03:57As soon as the project is finished, he will go back to his normal schedule.
04:02So that's why we say, I have been working late.
04:06Let's move on to the present perfect progressive.
04:09Now this one is a little bit tough.
04:12It's an ongoing action up to the present.
04:15And the duration is important.
04:18And we don't know if it's going to continue into the future or not.
04:23Here's an example.
04:24You have been running for an hour.
04:27Okay, you have been running for an hour.
04:30You see it in the diagram here.
04:32So the running started in the past and the running has been happening.
04:37It's been ongoing for one hour up to the present.
04:41We don't know if he's going to stop running or not.
04:45You could also use the contraction.
04:48You've been running for an hour.
04:51Now how about the negative form?
04:53You have not been running for an hour.
04:57Or you haven't been running for an hour.
05:00The question form?
05:02Have you been running for an hour?
05:05Now the third person, watch out here.
05:08I think you can guess what I'm going to say.
05:11She has been running for an hour.
05:14She has been running for an hour.
05:16Or you could say, she's been running for an hour.
05:20The negative form?
05:21She has not been running for an hour.
05:24She hasn't been running for an hour.
05:27Can you guess the question form?
05:30Has she been running for an hour?
05:33That would be a perfect question.
05:35Of course, you could say, where have you been running for an hour?
05:39Or why has she been running for an hour?
05:43The negative question is also possible.
05:47Haven't you been running for an hour?
05:49I'm surprised that you haven't been running for an hour.
