Try to figure out what to do to change into passive using these examples above, if you still don't get it let us know.
Isn't the above sentence 'Passive' rather than 'Active'?
Yoong Liatexample: Active: He was told to tell her.Yes, the sentence istself is in the passive voice. The infinitive (direct object) is in the active voice.
In any Active sentence there are two pieces: auxiliary verb(s) + main verb
For example: "He will tell her.": The "auxiliary verb" is "will", the main verb is "tell". In a sentence like "He will have told her.": The auxiliary verbs are "will" and "have" (piece 1), the main verb is "told" (piece 2).
To change into passive:
1- rewrite the auxiliary verb(s) after the subject
2- add "verb to be", depending on the auxiliary verb(s)
3- add the "past participle" of the main verb
Let's see an example of yours: "should finish"
1- rewrite the auxiliary verb(s) after the subject: should
2- add "verb to be", depending on the auxiliary verb(s): "Should" is a modal verb so the verb following must be in infinitive = "be"
3- add the "past participle" of the main verb: The "past participle" of "finish" is "finished"
So the passive is: SHOULD BE FINISHED
Try again now.
As for "will go", there's no object, "go" is an "intransitive verb" taking no objects, so you can't change it into the Passive voice. "Will have been gone" is wrong, it has no answer because it has no object.
Just a word of advice …
When we apply passive voice to a context, we should have an awareness if the intended context can receive the passive voice. Theoretically, at least in exercise, we can change active to passive voice with any verb. However, this is not always true in real life. Passive voice should be used with discretion and proper context. For instance, if I say “Mary was given plenty of warning before she was fired for her tardiness”, I intended Mary as my subject and the emphasis is on her. We don't have t ostate the name of the person who carried out the firing. In the active voice, we must state the subject who carried out the firing of Mary, whom in this case is the recipient of the act. Example: Mary’s manager gave her plenty of warning for her tardiness before firing her.
