Select the option that correctly expresses the given sentence in passive voice. The teachers of our school have already taken this training.

Correct — A. The active verb is have already taken — present perfect — so the passive has to stay present perfect.

Present perfect passive = has/have + been + past participle. The new subject is "this training", which is singular, so the auxiliary is has, not have.

That gives has already been taken, with "already" keeping its slot between the auxiliary and "been".

The agent phrase is carried across word for word: by the teachers of our school → option (a).

Why the others are wrong

• (b)
  This training has already been taken by the our school teachers. — The verb group is right, but the agent reads the our school teachers. An article cannot stand in front of a possessive determiner — English allows "the teachers" or "our teachers", never "the our".
• (c)
  This training was already taken by the teachers of our school. — Was taken is simple past. Changing the voice may not also change the tense, and this option turns a result that still stands into a finished past event.
• (d)
  This training has been taken by the teachers of our school. — The grammar is sound, but already has been dropped. Every adverb in the active sentence must survive the transformation, and losing this one loses the point of the sentence.

A voice change moves who occupies the subject slot. It does not move the time of the action.

So map the active verb onto its passive twin first: have/has taken (present perfect) becomes has/have been taken.

Then make the auxiliary agree with the new subject, not the old one. Here the old subject was plural (teachers) and the new subject is singular (this training), so have becomes has.

Adverbs of time such as already, just and never sit between the auxiliary and been: has already been taken.

Key facts

• Present perfect passive is formed as has/have + been + past participle.
• The passive auxiliary agrees with the new subject, so a plural active subject can still end up with "has".
• An adverb such as "already" goes between the auxiliary and "been" in a passive verb group.
• A determiner such as "the" cannot be placed in front of a possessive determiner such as "our".

Common traps

• Sliding to simple past because the shorter passive sounds smoother
• Making the auxiliary agree with the old subject instead of the new one
• Dropping an adverb such as already when the rest of the option looks correct
