How to make the Passive in English?

Use

Тhе Passive is used:

1. when the agent (the person who does the action) is unknown, unimportant or obvious from the context.

My purse was stolen оn the train. (unknown agent)

Не was arrested. (obvious agent)

The plants are watered every evening. (unimportant agent)

2. when the action is more important than the agent, as in processes, instructions,

events, reports, headlines, news items and advertisements.

Тhе local bank was robbed this morning. (news report)

Bread is baked in an oven for about 45 minutes. (process)

Taking pictures is not allowed. (written notice)

The Fine Arts Museum will bе opened to the public on November 14th. (formal notice)

We make the passive by putting the verb 'to be' into whatever tense we need and then adding the past participle. For regular verbs, we make the past participle by adding 'ed' to the infinitive.
