00:00:00,820 --> 00:00:05,580
En este vídeo vamos a ver la diferencia entre usar el presente y usar el pasado.

2
00:00:06,019 --> 00:00:10,279
En español lo hacemos igual. Yo puedo decir que yo juego con mis juguetes ahora,

3
00:00:10,820 --> 00:00:15,599
o que yo hoy juego con mis juguetes, que nos referimos a que estás jugando ahora,

4
00:00:16,320 --> 00:00:20,780
o podemos hablar de que yo jugué con mis juguetes en el pasado.

5
00:00:21,359 --> 00:00:23,940
Primero vamos a ver cómo se dirían las oraciones en presente.

6
00:00:23,940 --> 00:00:38,000
I play with my toys now or Today I play with my toys. This is in present. It's happening now.

7
00:00:38,820 --> 00:00:44,460
I pass the exam. I pass the exam now.

8
00:00:45,600 --> 00:00:51,979
I work in a hospital. Today I work in a hospital.

9
00:00:51,979 --> 00:01:03,280
I cook pizza with my mom. I cook pizza with my mom now. You do it now, in the present.

10
00:01:04,719 --> 00:01:19,280
I help my brother to study. Today I help my brother to study. I dance very well or I use the computer.

11
00:01:19,280 --> 00:01:30,560
These sentences are in present, but what if I talk about yesterday, yesterday I play with

12
00:01:30,560 --> 00:01:39,319
my toys. Esto sería como decir ayer yo juego con mis juguetes. En español tenemos que

13
00:01:39,319 --> 00:01:45,379
cambiar el verbo cuando nos referimos al pasado, ya no decimos ayer yo juego con mis juguetes,

14
00:01:45,379 --> 00:02:06,040
Decimos, ayer yo jugué con mis juguetes, yo aprobé el examen, yo trabajé en un hospital, yo cociné pizza con mi madre, yo ayudé a mi hermano a estudiar, yo bailé muy bien o yo usé el ordenador ayer.

15
00:02:06,659 --> 00:02:14,620
Vamos a cambiar las oraciones para que ahora nos refiramos a algo que hicimos ayer o en otro momento del pasado.

16
00:02:15,379 --> 00:02:20,939
Yesterday I played with my toys is not correct.

17
00:02:22,280 --> 00:02:29,479
In English we add to the verb these two things, or this one or this one.

18
00:02:29,740 --> 00:02:30,919
We have to choose.

19
00:02:31,979 --> 00:02:33,319
Let's see this one first.

20
00:02:35,219 --> 00:02:38,719
Yesterday I played with my toys.

21
00:02:39,259 --> 00:02:41,840
Now this sentence is in past.

22
00:02:41,840 --> 00:02:50,789
Yesterday I passed the exam.

23
00:02:53,069 --> 00:02:58,210
Yesterday I worked in a hospital.

24
00:03:00,550 --> 00:03:04,610
Yesterday I cooked pizza with my mom.

25
00:03:06,050 --> 00:03:10,669
Yesterday I helped my brother to study.

26
00:03:12,990 --> 00:03:16,610
Yesterday I danced very well.

27
00:03:17,569 --> 00:03:18,629
Pay attention here.

28
00:03:18,629 --> 00:03:21,750
Here we have two e's together.

29
00:03:22,969 --> 00:03:24,810
We don't need two e's.

30
00:03:25,270 --> 00:03:27,310
It's enough with one e.

31
00:03:28,009 --> 00:03:33,370
So in this case, if the verb ends in e,

32
00:03:33,830 --> 00:03:37,849
there's no need to write again e, e, e.

33
00:03:38,469 --> 00:03:43,189
Instead of this, we only write d.

34
00:03:43,189 --> 00:03:53,560
So, the verb in past ends in "-ed", "-ed", "-ed".

35
00:03:55,180 --> 00:03:57,560
Yesterday I used...

36
00:03:59,639 --> 00:04:01,560
...two "-es together".

37
00:04:02,819 --> 00:04:03,580
That's incorrect.

38
00:04:05,099 --> 00:04:10,560
This verb ends in "-e", so we write only a "-d".

39
00:04:10,560 --> 00:04:13,560
I used "-ed".

40
00:04:14,560 --> 00:04:19,620
Let's focus now on the verbs.

41
00:04:21,060 --> 00:04:24,959
If we talk in present, we just write the verb.

42
00:04:25,220 --> 00:04:31,120
The verb play, pass, work, cook, help, dance, use, or any other verb.

43
00:04:31,779 --> 00:04:37,819
But, instead of present, when we want to talk about the past,

44
00:04:38,060 --> 00:04:43,040
something that you did yesterday, or last month, or last week,

45
00:04:43,040 --> 00:04:46,000
We are going to add

46
00:04:46,000 --> 00:04:48,420
ED to the verbs

47
00:04:48,420 --> 00:04:50,600
Played

48
00:04:50,600 --> 00:04:55,480
Passed

49
00:04:55,480 --> 00:04:58,439
Worked

50
00:04:58,439 --> 00:04:59,199
Cooked

51
00:04:59,199 --> 00:05:02,339
Helped

52
00:05:02,339 --> 00:05:07,149
And here we have a verb

53
00:05:07,149 --> 00:05:08,509
that ends

54
00:05:08,509 --> 00:05:10,750
in letter E

55
00:05:10,750 --> 00:05:13,009
So I don't write this

56
00:05:13,009 --> 00:05:14,970
because now we have two E's

57
00:05:14,970 --> 00:05:15,449
together

58
00:05:15,449 --> 00:05:18,970
In this case we just write

59
00:05:18,970 --> 00:05:19,850
a D

60
00:05:19,850 --> 00:05:23,209
Danced, used.
