1 00:00:00,110 --> 00:00:09,029 good morning welcome back again to our online class today's content you're 2 00:00:09,029 --> 00:00:14,189 going to see that today's presentation is shorter than any other than other 3 00:00:14,189 --> 00:00:23,329 days and that is because the tense that we're going to look at today has a very 4 00:00:23,329 --> 00:00:35,250 simple structure in this tense is the past perfect um you're going to see that here we 5 00:00:35,250 --> 00:00:42,289 refer to the past simple too because it's necessary but today we're not going to look 6 00:00:42,289 --> 00:00:46,890 at them together we're not going to practice the two of them together that we will leave it for 7 00:00:46,890 --> 00:00:57,890 another day okay so in order to understand how the past perfect works i would like you 8 00:00:57,890 --> 00:01:07,969 to imagine or to picture yourself in a situation like the one that you have in the example 9 00:01:07,969 --> 00:01:18,909 Okay. So, first of all, we've got Sarah, who went to a party last week. 10 00:01:20,750 --> 00:01:28,150 Paul went to the same party, but they didn't see each other. 11 00:01:28,150 --> 00:01:41,290 and you know why because paul left the party at 10 30 and sarah arrived at 10 at 11 o'clock 12 00:01:41,290 --> 00:01:51,150 so this is paul saying goodbye at 10 30 and here is sarah arriving so it's impossible to see to 13 00:01:51,150 --> 00:02:01,069 meet each other, okay? So, when Sarah arrived at the party, Paul wasn't there. 14 00:02:01,069 --> 00:02:16,610 He had gone home. Had gone is the past perfect. In other words, we use the past 15 00:02:16,610 --> 00:02:31,430 perfect to talk about an action that happens in the past of the past so all 16 00:02:31,430 --> 00:02:40,310 these example all these party everything happened last week in the past so before 17 00:02:40,310 --> 00:02:48,650 Sarah went to the party, Paul had gone. Before that past action, Paul did something, which 18 00:02:48,650 --> 00:03:00,270 is going. So, the past of the past, we use past perfect for the past of the past. Let's 19 00:03:00,270 --> 00:03:09,849 see more in detail how it works. Here you have three more examples. When I woke up, 20 00:03:10,310 --> 00:03:13,330 The garden was all white. 21 00:03:14,129 --> 00:03:14,550 Can you imagine? 22 00:03:15,490 --> 00:03:20,650 So, before I woke up, it had been snowing. 23 00:03:20,650 --> 00:03:24,729 So, when I woke up, the garden was all white. 24 00:03:25,229 --> 00:03:27,889 It had snowed during the night. 25 00:03:28,370 --> 00:03:32,449 This action happened before than this one. 26 00:03:34,759 --> 00:03:35,539 Another example. 27 00:03:36,159 --> 00:03:41,020 I suddenly realized that I had left my mobile in the taxi. 28 00:03:41,020 --> 00:03:49,479 so first I left my mobile in the taxi and then I realized it when she got to 29 00:03:49,479 --> 00:03:55,639 class she realized that she hadn't brought her book so she didn't bring her 30 00:03:55,639 --> 00:04:00,099 book that's the action that happened first and then she got to class and she 31 00:04:00,099 --> 00:04:07,840 realized so the past of the past past perfect so we use the past perfect when 32 00:04:07,840 --> 00:04:16,060 we are talking about the past and we want to talk about an action that 33 00:04:16,060 --> 00:04:25,180 happened before, an earlier past action. Go back to the first example again. When 34 00:04:25,180 --> 00:04:30,879 I woke up the garden was all white, it had snowed during the night. It snows 35 00:04:30,879 --> 00:04:38,680 before I woke up. We make the past perfect. All this was about the 36 00:04:38,680 --> 00:04:45,100 use of the past perfect. If we focus on the form of the past perfect it is super 37 00:04:45,100 --> 00:04:55,779 hyper mega easy because what we have to use is this structure. We write the past 38 00:04:55,779 --> 00:05:03,100 of the verb to have which is had and then the past participle of the main 39 00:05:03,100 --> 00:05:12,519 verb in the negative form hadn't past participle this does not change for any 40 00:05:12,519 --> 00:05:21,579 person so it's always the same I he she had gone whatever doesn't matter if it 41 00:05:21,579 --> 00:05:27,699 is a question how would that be if it is a question we write the auxiliary first 42 00:05:27,699 --> 00:05:33,279 like you know what we always do had she gone that's it 43 00:05:33,279 --> 00:05:41,040 auxiliary had subject she passed with this in the rest of the sentence had she 44 00:05:41,040 --> 00:05:49,720 gone as you can see in example number two had is sometimes contracted to the 45 00:05:49,720 --> 00:05:54,139 And this is all that I have to say about the past perfect. 46 00:05:54,540 --> 00:05:56,019 You just have to practice, okay? 47 00:05:56,980 --> 00:06:04,420 So, again, revise your irregular verbs and go on into the practice of the book.
