Question

the past passive of this sentence : we had lost all hope
is : All hope was lost or all hope had been lost

Answer 1

Answer:

The correct passive form for "We had lost all hope" is ⇒ All hope had been lost by us.

The trick to get correct answer is,

⇒ First check the number of verbs in active voice.

⇒ Therefore the passive voice will have one more verb added to the number of verbs in active voice.

The reverse of this can be done for changing passive to active.

Example :

Active ⇒ They are eating fruits.(2 verbs)

Passive ⇒ Fruits are being eaten by them.(3 verbs)
