Active, Passive, Tenses and Modal auxiliaries

  1. Active Voice

Active voice is used to indicate the grammatical subject of the verb is performing the action or causing the happening denoted by the verb. With the active voice, you learn ‘who’ or ‘what’ is responsible for the action at the beginning of the sentence. In other words, the subject performs the action denoted by the verb. With help of active voice more powerful sentences can be build than passive voice.

Use of active voice:

  1. Active voice is used in a clause whose subject expresses the agent of the main verb.
  2. Subject can be easily identified by asking ‘who’ or ‘what’ to the verb.
  3. Sentences are short and easily understandable.

2.   Passive Voice

In Passive voice the sentence focus on object i.e. who/what is receiving the action and not on who/what is performing the action. In passive voice, the actor of the of the verb (action) is either understood at the end of the sentence or maybe not told. The passive voice is used in writing facts, truth, lab or technical reports in which the actor is not important or unknown, but the action happening on the object is very important.

Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.

Use of passive voice:

  1. It is used if it doesn‘t need to know or we don‘t know the actor performing the job.
    2. In the end of the clause or sentence “by” is prefixed to know the actor performing the job.
    3. It is used if we are more interested in the job than the actors who work.

Form of Passive

Subject + finite form of to be + Past Participle (3rd column of irregular verbs)

Example: A letter was written.

When rewriting active sentences in passive voice, note the following:

  • the object of the active sentence becomes the subject of the passive sentence
  • the finite form of the verb is changed (to be + past participle)
  • the subject of the active sentence becomes the object of the passive sentence (or is dropped)

Example:

This house was built in 1895.

This is a passive sentence. Compare:

Somebody built this house in 1895. (active)

This house was built in 1895. (passive)

We often prefer the passive when it is not so important who or what did the action. In this example, it is not so important who built the house.
