Look at the following sentences. Point out the verb, the subject and the object in each of these sentencesand change them into passive voice.

What’s the difference between active voice and passive voice?
Tense The active voice
The passive voice
The simple present
do/does am/is/are done
The present continuous
am/is/are doing am/is/are being done
The present perfect
has/have done has/have been done
The simple future be going to/will do
be going to/will be done
The simple past did was/were done
The past continuous
was/were doing was/were being done
The past perfect had done had been done
Point 1Usually 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 onmy 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 asmake, 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 voiceinstead 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 usedin 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.
It is hoped/believed/reported/thought/… that…. or
Sb. is hoped/believed/reported/thought/… to do sth.
(1) 人们希望他的身体很快会好起来 .
