  1. Hi, my name is alejandra.
  2. I'm an english teacher and today I want to explain you how to use the passive voice
  3. passive voice is a very difficult topic for most of my students
  4. but I think that if you pay attention to the rules,
  5. it might be very easy as it is very very similar to the passive voice in spanish.
  6. So um let's start and let's see if I can help with you in some of your doubts.
  7. So the first thing that we have to learn for a passive voice are the rules.
  8. So here I have some for you, let's go with number one impassive voice,
  9. The object becomes the subject.
  10. Yes.
  11. So we usually turn the object that comes at the end of the sentence
  12. to the beginning of the sentence and that we will see in a moment
  13. let's go to rule number two.
  14. It is much more important the action that the person who performs it.
  15. Yes, we really don't care about who did the action. But what was the action itself
  16. Rule number three,
  17. the main verb is always in passive participle.
  18. It is important to know that the passive voice can be used in every tense.
  19. You know, we have many tenses.
  20. All the simple tenses, the perfect tenses that continues or progressive tenses,
  21. the perfect continuous tenses.
  22. So in all of them passive voice is used
  23. but the main verb always goes in past participle.
  24. So then how can we know in which tense it is if all the verbs are in past participle,
  25. hmm.
  26. This is easy.
  27. The tense is given by the helping verb which is also known as the auxiliary verb.
  28. Yes, We always have a verb phrase,
  29. the main verb goes in past participle but the helping or
  30. auxiliary verb changes depending on the 10th of the sentence.
  31. Rule # five,
  32. the person or thing that performs the action can be
  33. not mentioned unless it's very famous or well known.
  34. It doesn't matter if the person who performs the action is a
  35. waiter or a chauffeur or an unknown person that nobody knows.
  36. We don't care, we care about what he or she did.
  37. But if it is a famous person,
  38. maybe from history or maybe an actor or maybe
  39. someone who the person who is talking to um you
  40. know the group of people who is talking nose
  41. then it is important to mention him or her.
  42. We always add the performer at the end of the sentence using the preposition by
  43. and this we will see in the next examples,
  44. I'm going to show you some examples of this using in one of them
  45. uh the performer because it is a famous person and not in the other.
  46. So let's see
  47. this is our first example,
  48. john Lennon wrote, imagine, imagine was written by john Lennon.
  49. This is a sentence in simple past and we know this because the
  50. main verb in the first sentence in the active sentence is in past tense
  51. and in the second sentence we have was which gives us the tense in past as you can see,
  52. the main verb is in past participle and here is a proposition by we used by
  53. because john Lennon was very famous.
  54. So um most of the people know who is, john who was, john Lennon
  55. in the second sentence. The thief has stolen my bike.
  56. We don't know who the thief is actually.
  57. We don't care, we just care about our bike being stolen.
  58. So my bike has been stolen these sentences in present, perfect.
  59. And we actually don't know who the thief was. So we don't have to mention him.
  60. Then we have another example.
  61. This is in the present continuous, she is washing the dishes,
  62. the dishes are being washed again.
  63. We don't mention the person as we don't care who is she.
  64. It is important to notice that when our verb,
  65. the main bourbon active is in a continuous chance which is I N G O
  66. B I N G has to pass also to be shown in the helping verb.
  67. But we are using in passive voice
  68. and to finish,
  69. I am going to show you um an example of how we change the order in our sentence uh to make
  70. a sentence from active to passive as you can see here
  71. and you can see with the lines in different colors.
  72. Kris makes cakes, the object is cakes and it comes to the beginning of the sentence.
  73. It turns into the subject.
  74. So now cakes is our subject cakes are made Are is the present tense,
  75. as you can see in the active sentence.
  76. Makes is a present tense are made made is the past participle of
  77. the verb make. And then we say by chris adding the preposition passive,
  78. I'm in the preposition by Sorry?
  79. Uh so I hope this um helps you understand better this topic,
  80. which is when most of my favorites
  81. and that's it. Thank you for watching.
