Present Perfect with Lengths of Time - Lesson 4

So, we know we can use present perfect with experiences until now. Right, well, how do we use it with lengths of time? Well, the same applies in a question which asks how long if that action still continues. Now, you use present perfect if not past simple let me give you an example. Oh, you study English cool. How long she wants to say? I study English five years. still continues. Now, remember still continues. Now, so present perfect. What’s the sentence? Now, we have two options here. We could say I have studied or I have been studying for five years, five years ago. Until now studying English still continues present perfect. Again, we can use two options here present perfect simple or continuous we explain the difference between those in the next video.

But, first let’s look at another example. For example, for one month she studied Italian. She does not study Italian. Now it finished and started in the past. So, what could she say? Present perfect or past simple? Of course in this case she uses past simple. Because, that month happened in the past and it’s a finished time. It doesn’t continue now. So, this is me Ali and in my life. My job is a teacher and I want to say I’m still a teacher. Now, the length of time is nine years. What can I swallow nine years is a long time. Jesus Christ, ah, anyway what’s my sentence? Me teacher nine years.

Still continues. Now, easy, right it still continues. Now I have been teaching or I have taught English for nine years, god damn it. So, long and before teaching my job was in an office for one year. How can I say that? of course that time was finished. I don’t work in an office now. So, I worked in an office for one year and your next question, yes, this is in continuous. So, we could make this past continuous I was working in an office for one year. That’s fine too. Another example and now comes the part of our story, it gets a little bit sad. Ah so, this next example is quite sad.

But, you’ll probably remember afterwards. So, in this case the guy has a dog and she wants to know how long have you had a dog. Compare this with how long did you have a dog past simple. Because, the dog has gone to puppy heaven. So, to compare the two this one the dog is still there. He still has the dog. Yay, how long have you had a dog? This one, the dog is dead. How long did you have a dog passed simple. because, he doesn’t have a dog. Now it was only in the past. I’m sorry a super common mistake with this. I see it very often is with since and for let me give you an example. For example, this one I worked there since 2010 until 2012. Now, yes, since gives the reference of time. But, it’s a reference of time in the past which still continues.

Now, so, if you use since, you must have a present perfect which means you must have a present perfect situation. So, for this, it doesn’t work. Because, that’s not this year. So, for this sentence, don’t use since. Use from I worked there from past eight to or until past date. just to remember since is a past date until now. So, let’s use my example again. I have been teaching since 2007. I’m still a teacher now. So, it’s okay to use since. So, since gives the time reference in the past 2007 if I want to give the length of time I must use for so the full sentence I have been teaching since 2007 or I have been teaching for nine years. That is ridiculous .

My god. if a couple are still together she could say I’ve been dating Harry Styles for one year. But, if they break up, then now they are not together and dating happen in the past. It doesn’t continue. Now, she wants to say this how can she say it? I dated all yeah continuous. I was dating Harry Styles for one year. So, I hope that all makes sense for lengths of time. If it still continues present perfect simple or continuous. If it’s finished past simple past continuous. Ready for the next lesson.
