UNIT 41. passive (1) (is done/was done)

A. Study this example:

This house was built in 1930.

'Was built' is passive. Compare active and passive:

Somebody built this house (object) in 1930. (active)

This house (subject) was built in 1930. (passive)

We use an active verb to say what the subject does:

* My grandfather was a builder. He built this house in 1930.

* It's a big company. It employs two hundred people.

We use a passive verb to say what happens to the subject:

* This house is quite old. It was built in 1930.

* Two hundred people are employed by the company.

B. When we use the passive, who or what causes the action is often unknown or unimportant:

* A lot of money was stolen in the robbery. (somebody stole it but we don't know who)

* Is this room cleaned every day? (does somebody clean it?--it's not important who)

If we want to say who does or what causes the action, we use by...

* This house was built by my grandfather.

* Two hundred people are employed by the company.

C. The passive is be (is/was/have been etc.) + the past participle (done/cleaned/seen etc.):

(be) done (be) cleaned (be) seen (be) damaged (be) built etc.

For irregular past participles (done/known/seen etc.), see Appendix 1.

Study the active and passive forms of the present simple and past simple:

Present simple

active: clean(s)/see(s) etc.

Somebody cleans this every day.

passive: am/is/are cleaned/seen etc.

This room is cleaned every day.
