We often use the passive in scientific or technical processes. Oil and gas are found beneath the ground or sea. when it is obvious who performed the action, e.g. teachers, or we do not want to use a general subject e.g. people, they. Aztec boys were trained to fight. The missing children have been found safe and well. more often in formal speech and writing than in everyday speech.

Passive (2) Reporting verbs The passive is often used with say, believe, understand, know and similar verbs used in reporting speech to avoid an impersonal they or people. People say that John Wilson lives in New York. John Wilson is said to live in New York John Wilson is said to live in New York.
Other verb forms can also be reported in this way They say John Wilson is travelling in Africa. John Wilson is said to be travelling in Africa. People say John Wilson has arrived in Australia. John Wilson is said to have arrived in Australia
Have/Get something done When someone does some work for us, we can use have something done Last year I had new tiles put on the roof. I'm having my hair cut this afternoon.
The same construction can describe bad luck caused by an unspecified person. Peter had his car stolen last week. And then he had his leg broken playing football
Using get instead of have in the previous above would be more informal. Using get can also suggest managing to do something difficult. It was difficult but we got the painting done in the end.
