Uso De Passive Voice

Passive voice.
The key to pass the sentences to passive voice is look carefully the main verb. Normally we speak in active voice… for example: Rosa steals the money. But to transform that sentenceto passive… we look the verb STEAL (that in this case is with “S” because we are using “Rosa” (third person)) so, it is in present and the passive would be like this: The money IS STOLEN by Rosa.Active Voice:
Pronoun + verb + complement.
Rosa/ She + Steals + the money.
Passive Voice:
Complement + be + past participle of the verb + by + object.
The money+ is(because “THE MONEY” is thirdperson) + STOLEN + by + her.
The difficulty of transforming from active to passive is… the tense of the “BE” because if active sentence is in present we have to write the “BE” with “Are” if the object isplural, “IS” if the object is singular and the verb in past participle is the same in both cases (present and past).
Examples:
-Luis took the elevator twice.
*The elevator was taken by Luis twice.-Roberto writes his homework really fast.
*The homework is written really fast by Roberto/ him.
-Karla crosses the line.
* The line is crossed by her/ Karla.
-You take the class.
*The class IStaken by you.
-You took the class.
* The class WAS taken by you.

-Someone painted the houses.
*The houses WERE painted. (In this case is not necessary to write “BY SOMEONE”)
-I paint thehouses.
*The houses ARE painted by me.
Summarizing... The only thing you have to be sure of… is THE TENSE WHERE THE MAIN VERB OF THE ACTIVE VOICE IS… if you are talking in present the verb “BE” is goingto be (depending if it’s plural or singular) with “ARE” or “IS” and the next verb is always in PAST PARTICIPLE. And if the verb in the active is in PAST you have to use “WAS” or “WERE”(depending ifit’s plural or singular).
When you use “twice”, “always”, “really fast” “4 times a day”… etc.. it isn’t important where you write them…
-I drink water eight times a day.
*Water is drunk by me eight...
