Question

tthe police have caught the thief change into passive voice​

Answer 1

The thief has been caught by the police.

Or

The thief has been caught.

In the given question, we are required to change a sentence from active to passive voice. While doing so we should keep few things in mind. They are as follows-

• There should be an addition of the word 'by' in a sentence that is in passive voice. However, that is done in sentences that mention the subject at the end.
• There must be a change in the tense of the verb as well. Here the verb has been changed from 'have caught' to 'has been caught'.
• The subject is usually mentioned at the end.
• It is not always mandatory to mention the subject. In certain cases where the subject can be easily guessed or assumed, we can omit mentioning the subject.
