What is the best way to change this sentence from active voice to passive voice? You must take the wind, the clouds, and the sky into account when describing the landscape.

When describing the landscape, the wind, the clouds,

and the sky must be taken into account.

Active voice uses the agent (person doing the action) first.

He threw the ball.

The passive voice puts the object first and the agent last.

Usually, the two switch and the verb changes to some form of to be, followed by a participle and the word by.

The ball was thrown by him.

Here is our sentence in the active voice:

You must take the wind, the clouds, and the sky into account when describing the landscape.

To use the passive voice, we need to put the object first.

The verb here is must take with the object being the wind, the clouds, and the sky.

The wind, the clouds, and the sky must be taken into account when describing the landscape.

A lot of times, your ear will be able to tell you what's right and wrong. There are some things I'm not sure about, like how the "you" disappears because we put the sentence into the imperative.

*You could also put "when describing the landscape" at the beginning of the sentrence with a comma, but this isn't necessary.
