     UNIT 25

   In order to form a passive2 sentence, we must bear in mind the following:

     —The direct object of the active becomes the subject of the passive.

     —Then, we add the verb be + the past participle of the active verb.

     —When we have a direct object and an indirect object in the active, both of them can be the subject of a passive sentence, but the indirect object3 is usually preferred as the subject of a passive sentence. If we wish to give emphasis to the thing (DO) rather than the person (IO), we make the direct object the subject of the passive sentence:
       Somebody gave her (indirect object) an ice lolly (direct object). (active)
       Somebody gave an ice lolly to her. (active)
       She was given an ice lolly. (passive→indirect object)
       An ice lolly was given to her. (passive→direct object)
       My mother has bought me a cardigan. (active)
       My mother has bought a cardigan for me. (active)
       I have been bought a cardigan. (passive→indirect object)
       A cardigan has been bought for me. (passive→direct object)

     —If the information given by the subject of the active is important, it must be mentioned in the passive by using by4 + the subject of the active. This is called "the agent". An active sentence like Someone stole my car becomes My car was stolen in the passive. We cannot say My car was stolen by someone because "someone" does not provide any useful information. Compare the following example with the one just seen: Peter stole my car→My car was stolen by Peter. In this case, the agent is necessary because if we remove it, we omit some important information. A sentence such as The police arrested the thief becomes The thief was arrested in the passive, as there is no need to mention the agent here, since it is already implied by the context that the job of the police is to do things of this sort.

   Change the following sentences from the active voice to the passive voice.

   The window cleaner cleans these windows once a week. (active)

   I would like you to send me A COPY OF THE CONTRACT. (active)

10 Example:
   He saw an ice-cream van park in front of his house. (active)
   An ice-cream van was seen TO park in front of his house. (passive)

   Some verbs are followed by an object + an infinitive without to, but take a to-infinitive in the passive. For more details, see unit 23, section 5.

a  They made him work in shifts.
b  He heard her say that her van was in its last legs.
c  Everyone watched him strike her with a stick.
d  They made us confess everything.

   He is said to be a raver. (passive)
   It is said (that) he is a raver. (passive)
   People say (that) he was a raver. (active)
   He is said to have been11 a raver. (passive)
   It is said (that) he was a raver. (passive)

   The two passive constructions seen above are synonymous and only possible with verbs such as say, think, believe, consider, find, know, report.

a  They claimed he stole/had stolen her purse.
b  They expect that the match will take place on Friday evening.
c  People think she is touched.
d  They alleged that he robbed/had robbed the jeweller's.

12 Examples:
   She suggested breaking into the house by night. (active)
   She suggested that they should break into the house by night. (active)

   They advised us to buy a new tractor. (active)
   They advised buying13 a new tractor. (active)
   They advised that we should buy a new tractor. (active)
   They advised that a new tractor should be bought. (passive)

   They decided that they should not lend him ANY MONEY. (active)
   They decided that he should not be lent any money. (passive)
   They decided that NO MONEY should be lent TO him. (passive)

   After some verbs we can have two structures in the active: a gerund or an infinitive and a should-construction; the latter being more formal. In the passive, the should-construction is required, unless we have a verb such as "advise", in which case the indirect object may be the subject of a passive sentence; thus, we can avoid using "should". For further information, see unit 22, section 36. Despite what we have seen here, there are other options, but they are usually less common than the ones used in this section. For these options, see the next section.

a  She urged her boss to expand the business.
b  He ordered14 his men to take up their positions right then.
c  The authorities recommended not making any fires in the area.
d  The Prime Minister insisted upon reducing the public expenditure.
e  We suggested employing another accountant.

13 Examples:
   People have demanded that the government should create more jobs. (active)
   It has been demanded that more jobs should be created. (passive)
   They decided15 not to lend him any money. (active)
   They decided that they should not lend him ANY MONEY. (active)
   It was decided not to lend him any money. (passive)
   It was decided that he should not be lent any money/that NO MONEY should be lent TO him. (passive)
   People suggested16 not demolishing the building. (active)
   People suggested that no-one should demolish the building. (active)
   It was suggested not demolishing the building. (passive)
   It was suggested that the building should not be demolished. (passive)

   We can use it as a preparatory subject of a that-clause, an infinitive construction or a gerund phrase to make a passive sentence, as has just been seen above. Nonetheless, you must take into account that this is only possible with some verbs, such as "demand", "decide" and "suggest". Compare this section with the previous one.

a  They have recommended not to use dynamite in the mine.
b  They have recommended that nobody should consume this trademark of cheese, as they say that some batches are off.
c  One may well think that one should put a traitor to death.
d  They have announced that they are going to cut down public spending.
e  People are demanding to know the whys and wherefores of their decision.

14 Examples:
   I had/got my fountain pen pinched. (= Somebody pinched my fountain pen.)
   We had/got our van fixed yesterday. (= A mechanic fixed our van yesterday.)

   We use have/get something done17 to denote that somebody does something to us or for us. Get is colloquial, and may indicate some sort of difficulty or effort, or the idea of having something to do. For additional information, see units 6 (part 4, sections 5 and 6) and 23 (section 10).

a  A translator is going to translate this letter into English for us.
b  This tap is dripping. We'll have to employ a plumber to mend it.
c  Somebody bruised my eye in a fight.
d  Someone has broken my spectacles.

f  They have promised us the earth.
g  He proposed our giving them a pay rise.
h  I'd love you to take me to the opera tonight.
i  She's not responsible for telling the enemy our intentions.
j  He allows18 his students to use dictionaries in his examinations.
k  Somebody helped her to exterminate the plague of rats.
l  The government has decided to spend more money on education.
m  The murderer had ripped the phone wires out so that no-one could ring the police.
n  Her boss sent her to London last month.
o  I'm sick and tired of people taking me photographs.
p  A mechanic is going to check my brakes.
q  We saw and killed the enemy when they were sliding into the barracks.
r  We hate people ordering us around.
s  The painter is painting my bungalow.
t  People believe that he has not gone out with a woman in his life.

w  We saw her speaking to Mrs Green.
x  Peter Jones holds the world record for javeling throwing.
y  We'll have to invest more money in the project.
z  The strangler strangled her with a scarf.

1  Not all transitive verbs take the passive voice:
     She has a car (active)
     *A car is had. (This passive construction is not correct.)

   Reflexive and reciprocal pronouns cannot be the subject of a passive sentence:
     I sent myself a bunch of flowers. (active)
     *Myself was sent a bunch of flowers. (This passive structure is impossible.)
     We kissed each other. (active)
     *Each other was kissed. (This passive sentence is not possible.)
2  Deserve, need, require and want plus a gerund have a passive meaning: This plant needs watering/to be watered. For more details, see unit 23, section 18.
3  This passive construction is impossible in some languages; for instance, in Catalan and Castilian.
4  Occasionally, another preposition can occur in place of by:
     What she said amazed me.
     I was amazed by/at what she said.

   Note also:
     My heart filled with sadness.
     Sadness filled my heart

     My heart was filled with sadness. (not by sadness)
5  Note the word order.
6  Swear in is normally used in the passive.
7  Infinitives continuous are avoided in the passive:
     They can't be cleaning the swimming-pool.
     *The swimming-pool can't be being cleaned.
(This structure is not generally used so as to avoid the combination "be being".)
8  Perfect continuous infinitives are avoided in the passive:
     They ought to have been fixing my car.
     *My car ought to have been being fixed.
(This construction is not normally used so as to avoid using "been being".)
9  In order to avoid saying "been being", we do not usually put perfect continuous tenses into the passive voice:
     They have been attacking us for the last two days.
     *We have been being attacked for the last two days.
(Avoid this.)
10  This object is singular.
11  The perfect infinitive refers to a previous action.
   Another instance: The authorities reported (a later action) that he was murdered/had been murdered (an earlier action) with a knife.He was reported to have been murdered with a knife/It was reported that he was murdered/had been murdered with a knife. Compare this with the following:
     People said he was handsome.
     He was said to be handsome.
("to have been handsome" would imply that he was not handsome any more or that he was already dead.)
     It was said (that) he was handsome.
12  The subjunctive is also possible with these verbs; the only thing you have to do is to leave out the word should: She suggested that the house be broken into. For the employment of the subjunctive, see unit 22, sections 35, 36 and 37.
13  See unit 23, section 7.
14  This structure indicates that he told his men direct; the one with should, that he told somebody else, which is why it would be much better not to use the should-construction here.
15  Note the position of the agent:
     His employer decided not to lend him any money.
     His employer decided that he should not lend him any money.
     It was decided by his employer not to lend him any money.
     It was decided by his employer that he should not be lent any money/that no money should be lent to him.

16  Notice the position of the agent:
     The authorities suggested not demolishing the building.
     The authorities suggested that no-one should demolished the building.
     It was suggested by the authorities not demolishing the building.
     It was suggested by the authorities that the building should not be demolished.

17  However, it is possible to say the following as well:
     My fountain pen was pinched.
     Our van was fixed yesterday.

18  See unit 23, section 7.
