Voice change---Perfect Tenses
In perfect tenses we use the past participle form of the main verb in the Active voice too. The rules for voice change dictates that we have to use the past participle form of the main verb in the passive voice. But how can we do that? The main verb in the active voice is already in the past participle form. Can we 'double' it? We cannot. So? There is a way-out of course. again we have to take the help of the BE verb. The past participle form of the BE verb is BEEN. We have to use it. Let us take some examples;;
1. Ranjit Guha has written a beautiful poem. (Active)=A beautiful poem has BEEN written by Ranjit Guha.(Passive).
2. Debolina has painted an awesome landscape.(Active)= An awesome landscape has BEEN painted by Debolina.
Negative and interrogative forms are not discussed here because I am sure you can write them. Use NOT after has/have and you will get what you want.
In case of past perfect tense just use had in place of has or have.
In case of future perfect tense the use only HAVE after will or shall. All the other rules are same. No problem whatsoever.
Just identify the following sentences .
1. The picture has been taken by Apratim.
2 .Had the monument been built by the king of Burdwan?
3. The task will have been finished by me before you come back
4 The chair has not been broken by Mamoni.
I am sure you can identify the sentences easily. In our next lesson we shall discuss some peculiar problems. Till then. H A P P Y L E A R N I N G **
