THE
PASSIVE VOICE
Compare the two sentences:
Your little boy broke my kitchen window this morning.
That window was broken by your little boy.
The first kind of sentence is called
"active". The second kind of sentence is called "passive".
Passive structures are
used when we want to talk about an action, but we are not interested in saying
who or what did it.
Those pyramids were built around 400 A.D.
Too many books have been written about
the second world war.
Passives are very
common in scientific writing, and other kinds of expression where we are most
interested in events and processes: in things that happen.
PASSIVE
VERB-FORMS
Passive
verb-forms are made with:
TO BE + PAST PARTICIPLE
Present simple: English
is spoken here.
Present continuous: The
house is being painted.
Past simple: I
wasn't invited, but I've come
anyway.
Past continuous: I
felt as if I was being watched.
Present perfect: Has Mary been told?
Past perfect: I
knew why I had been chosen.
Future: You'll be told in advance.
Future perfect: Everything
will have been done by the 26th
Going to: Who's
going to be invited?
Modal structures: The
house should be cleaned.
You
might have been hurt.
PASSIVE: by + agent.
In sentences like:
The trouble was caused by your mother
the part of the
sentence introduced by by is called the agent.
The agent is only expressed when it is important to say who or what
something is done by. In most passive sentences, there is no agent.
A new supermarket's just been opened.
I'm always being asked for money.
With is used when we talk about an instrument (tool, etc.) which
helps the agent to do an action.
He was shot (by a policeman) with a revolver.
PASSIVE: verbs with two
objects.
Many verbs, such as give, send, show, lend, explain, invite, ask,
tell, teach, pay, promise, offer.
can be followed by two objects, which usually refer to a person and a
thing.
She gave her sister a book.
When these verbs are
used in the passive, there are two possibilities.
Her
sister was given a book.
A book
was given to her sister.
Most often in such
cases the person becomes the subject of the passive verb.
I've
been sent a lot of information.
You
were lent ten
thousand pounds last year.
We
were shown all the different ways of making whisky.
