Write A if the verb is in the active voice and P if it is in the passive voice. Then, rewrite the sentence using a verb in the opposite voice, adding or dropping words as necessary.

1. The ship took in all the cargo.

A: A = active voice.
All the cargo was taken in by the ship.

2. The groans of the dying turned the scene into almost inconceivable horror.

A: A = active voice.
The scene was turn into almost inconceivable horror by the groans of the dying.

3. Two of the wretches were drowned.

A: P = passive voice.

4. Eventually we were landed on Barbados.

A: P = passive voice.

(I'm not sure about this one.)

All are right.

4. P = passive voice.

Eventually Barbados was landed on by us.
(Well, that's quite a peculiar way to visit a destination!)

Actually, sentence 4 is already in the active voice. So the corrected answer is:

4. Eventually we landed on Barbados.

A: P = passive voice.

Eventually Barbados landed us.
(I'm not sure about this one.)
