Look at the following sentences. Point out the verb,

the subject and the object in each of these sentences

and change them into passive voice.

We keep food in the fridge.

The boy broke the glass.

You must close the windows and the door.

Food is kept in the fridge.

The glass was broken by the boy.

The windows and the door must be closed.

What’s the difference between

active voice and passive voice?

Point 1

Usually the doer of the action needn’t be

mentioned in the passive sentence, but if

it is needed, we use by to introduce the

doer of the action. For example,

How can it be used in other ways?

( It is difficult to say who the doer is.)

Upon reaching the top of the mountain, a

feeling of happiness and a sense of

achievement will be experienced.

( It is not necessary to mention the doer.)

Point 2

When a verb is followed by two objects,

either of the objects can be used as the

subject in the passive sentence. However,

you should know the difference between

using the person and the thing as the subject.

For example:

Our teacher often tells us some interesting stories

in English.→

We are often told some interesting stories in English.

Some interesting stories are often told to us

in English.

My friends gave me some nice presents on

my birthday.→

I was given some nice presents on my birthday

by my friends.

Some nice presents were given to me on my

birthday by my friends.

My mother will make us a cake this Saturday.→

We will be made a cake by my mother

this Saturday.

A cake will be made for us by my mother

this Saturday.

Point 3

When an infinitive is used as an object

complement after some verbs, such as

make, let,notice, observe,see, watch, or hear, in the active voice, the infinitive maker to should be omitted,but if the sentence is changed into the passive voice, to should be used before the infinitive. More examples:

I often hear the girl play the piano in the

afternoon.→

The girl is often heard to play the piano in

the afternoon.

The teacher makes his students

write a composition every week.→

The students are made to write

a composition every week.

Point 4

Get can also be used in the passive voice

instead of be. For example,

My bike got stolen last night.

You’d better get changed quickly, for the

party will begin soon.

This window seems to have got broken.

Point 5

Some verbs used in the active

give a passive meaning. For example,

This sweater washes well.

The pen writes smoothly.

Point 6

Some transitive verbs cannot be used

in the passive voice, for these verbs

indicate states not actions. For example,

I like pop songs and often listen to them.

He has a big house near the river.

You can depend on her to deal with the situation.

There are two special sentence patterns

which can be used in the passive voice.

Sb. is hoped/believed/reported/thought/… to do sth.

(1) 人们希望他的身体很快会好起来.

It is hoped that he will be better soon.
