Passive
Using the active and passive voice
An active sentence like I drank two cups of coffee has the subject first (the person or thing that does the verb), followed by the verb, and finally the object (the person or thing that the action happens to). So, in this example, the subject is I, the verb is drank and the object is two cups of coffee. |

But, we don't always need to make sentences this way. We might want to put the object first, or not say who did something, for lots of reasons (see the explanation further down the page).
In this case, we can use a passive, which puts the object first: for example, two cups of coffee were drunk. We can add by me if we want, but it isn't necessary.
How to make the Passive in English We make it by putting the verb 'to be' into whatever tense we need and then adding the past participle.
(For regular verbs, we make the past participle by adding 'ed' to the infinitive -play becomes played)
Verbs with two objects
Some verbs that have two objects can make two different passive sentences: For example: ‘give’ - Active: He gave me the book / He gave the book to me.
You can choose either of the two objects to be the subject of the passive sentence.
Passive: I was given the book (by him)/ The book was given to me (by him)
Other verbs like this are: ask, offer, teach, tell, lend, promise, sell, throw. Try an exercise about this here

When should we use the Passive?
- When we want to change the focus of the sentence:
- The Mona Lisa was painted by Leonardo Da Vinci. (We are more interested in the painting than the artist in this sentence)
- When who or what causes the action is unknown or unimportant or obvious or ‘people in general’:
- He was arrested (obvious agent, the police).
- My bike has been stolen (unknown agent).
- The road is being repaired (unimportant agent).
- The form can be obtained from the post office (people in general).
- In factual or scientific writing:
- The chemical is placed in a test tube and the data entered into the computer.
- In formal writing instead of using someone/ people/ they (these can be used in speaking or informal writing):
- The brochure will be finished next month.
- In order to put the new information at the end of the sentence to improve style:
- Three books are used regularly in the class. The books were written by Dr. Bell. (‘Dr. Bell wrote the books’ sound clumsy)
- When the subject is very long:
- I was surprised by how well the students did in the test. (More natural than: ‘how well the students did in the test surprised me')
