1
00:00:00,620 --> 00:00:25,460
Okay, we are going to start with the past. The past is what happened the other day. For example, yesterday, the other day, last weekend, last week, or Friday from the last week, or last year, the last summer, the last Christmas. It's everything in the past.

2
00:00:25,460 --> 00:00:45,100
Okay. And for example, how do we do this? For the verb to be, we have today I am at school. So today I am at school. But yesterday, yesterday I was at the school.

3
00:00:45,100 --> 00:00:59,179
When I have I, or see, or he, or it, when we are talking about a thing, we use it, we change am or is for was.

4
00:00:59,179 --> 00:01:14,859
today they are at home today they are home yesterday they were at home they were at home

5
00:01:14,859 --> 00:01:26,799
when we have they or you or we we change are and we put were and that is how we talk about

6
00:01:26,799 --> 00:01:37,480
about what are they or what, where are they or what are they, okay? For example, if we

7
00:01:37,480 --> 00:01:50,359
are speaking about the time, like before, we can say today the weather is sunny. For

8
00:01:50,359 --> 00:02:06,750
example today it is sunny but maybe yesterday it wasn't sunny what was the

9
00:02:06,750 --> 00:02:25,009
weather like yesterday yesterday it was cloudy for example so we are speaking

10
00:02:25,009 --> 00:02:40,169
about another time, in the past. Another example, okay. Weren't you at school on Friday? I'm

11
00:02:40,169 --> 00:02:57,530
speaking about the last Friday. Weren't you at school on Friday? Weren't you? Remember,

12
00:02:57,530 --> 00:03:20,090
Last Friday was the Father's Day. There wasn't a school. So, the answer is no, I wasn't. Were you at home on Friday?

13
00:03:20,090 --> 00:03:38,229
were you at home on friday yes i was so when we answer a question we need to give a complete

14
00:03:38,229 --> 00:03:46,949
a full sentence a complete answer okay so no i wasn't yes i was okay
