The document provides instructions on how to change sentences from active to passive voice. It explains that only transitive verbs can be passivized and lists the steps to passivize as: 1) make the object of the active sentence the subject of the passive sentence, 2) add the auxiliary "be" in the correct tense, and 3) add the main verb in its past participle form. It provides examples of applying these steps to sentences in different tenses and with different auxiliaries. It also discusses how the tense of the passive sentence is determined by the auxiliary "be" and preserving tense when changing between active and passive.

1. Relating Sentences - Passive Active: Mary sang a song . Passive: A song was sung by Mary. Active: John ate the cake . Passive: The cake was eaten by John. The object of the active sentence becomes the subject of the passive sentence . The subject of the active sentence becomes an optional argument of the passive sentence . This is called a “ by phrase ”

Sue will watch a movie.  5. Bill likes Mary.  6. We had fun.  7. She has had a baby.  8. I will believe her.  A cigar is being smoked. Bill was hit. A book was being read.

11. Active and Passive - Argument Structure What is the argument structure : Sam kissed Jane. kiss : verb; 1 2 NP NP 2. Jane was kissed by Sam. kiss (passive) : verb; 1 (2) NP PP 3. Jane was kissed. kiss (passive) : verb; 1 (2) NP PP Remember the “ By- Phrase” is optional! When there’s no By-Phrase the sentence is a Truncated Passive

12. Active and Passive - Argument Structure What is the argument structure : Bill washed his car. wash : verb; 1 2 NP NP 2. The car was washed. wash (passive) : verb; 1 (2) NP PP 3. The bills were paid. pay (passive) : verb; 1 (2) NP PP

13. Convert to Truncated Passives 1. The lions chased the gazelles. 2. Clark walked around the campfire. 3. You can use those. 4. They will make a pie. 5. They had discovered a treasure. 6. We were watching this DVD yesterday. 7. Many farmers raise sheep. 8. GM has manufactured cars for decades. 9. We had lunch. 10. They will publish the book.

14. How to recognize a passive sentence? Passive sentences always contain the auxiliary “ be ”, followed by a verb in the past participle form . Example : Passive: John was kissed . Active: John was kissing Mary. II. Passive sentences contain a verb that selects (at least) two arguments , yet one of these arguments is always optional, and could only appear in a by-phrase ! Passive: John was kissed (by Mary).

15. Active or Passive? 1. They bought the house by the railroad tracks. 2. Their daughter had been selected for that honor. 3. Mary was enjoying the cake by herself. 4. The monument is being designed by a known sculptor. 5. Billy was staying at that hotel by the beach. 6. The milk was once delivered every morning. 7. The population of N.Y has increased by a million. 8. The judge has been detained by his clerk. 9. The door will be locked by the night custodian. 10. The investigator was walking by the courtroom.

16. Subjects Note what the book says about Subjects of passives : The book says that in passive sentences the subject does not come before the verb . This is a serious mistake!!!

17. Subjects Two important properties of Subjects are : I. Only s ubject pronouns can be subjects – 1. I repaired this computer. 2. This computer was repaired by me .  “ me ” cannot be the subject of sentence 2. II. Only the Subject “agrees” with the verb – 1. They like cake. 2. He like s cake. 3. Cake is liked by them. 4. Cake is liked by me. 5. Cakes are liked.

19. Relating Sentences - Questions  Every declarative sentence corresponds to a “yes/no” interrogative sentence – 1. She has been living in N.Y. all her life. 2. Has she been living in N.Y. all her life? 3. John will study tonight. 4. Will John study tonight? To form a yes/no question we do – Subject – Aux. Inversion.

20. The Auxiliary “ do ” John loves basketball. Does John love basketball? If there is no auxiliary , we add the auxiliary “ do ” . Aux . “ do ” requires the verb that follows it to be in the Base Form ! Aux . “ do ” determines the tense of the sentence: “ do ” / “ does ” – Present simple “ did ” – Past simple

21. Relating Sentences - Negatives Every positive sentence corresponds to a negative sentence – 1. John will eat the cake. 2. John will not eat the cake. 3. Mary has been singing at the opera. 4. Mary has not been singing at the opera.  To make a sentence negative we add the word “ not ” after the first auxiliary .

22. The Auxiliary “ do ” 1. John loves basketball. 2. John Does not love basketball. If there is no auxiliary , we add the auxiliary “ do ” . Aux . “ do ” requires the verb that follows it to be in the Base Form ! Aux . “ do ” determines the tense of the sentence: “ do ” / “ does ” – Present simple “ did ” – Past simple

23. An Important Exception – The verb “ be ”  We form a question by doing: Subject – Aux. Inver.  If there is no Aux., we add the auxiliary “ Do ”.  We form a neg. by adding “not” after the first Aux.  If there is no auxiliary, we add the auxiliary “ Do ”. But look what happens when the verb is “ be ” : 1. John is a student. Question : Is John a student? Negative : John is not a student. Conclusion : For purposes of question or negative formation the verb “ be ” behaves like an auxiliary . No Aux. added!!
