Active voice

[lee ying]

help me ! I don't understand how can I do the active voice after a present continous passive or present perfect passive:
for example.
THE WORLD WE LIVE IN:

PRESENT CONTINUOS PASSIVE
THE STREETS ARE BEING POLLUTED BY PERSONS THAT TRHOW THEIR TRASH ON THE FLOOR.

PRESENT PERFECT PASSIVE
THE STREETS HAVE BEEN POLLUTED DUE TO PEOPLE THROW THEIR TRASH IN EVERYWEHRE.
ACTIVE VOICE:

HOW IS GOING TO BE THE ACTIVE VOICE,YOU CAN USE PRESENT CONTINUOS OR PRESENT PERFECT, PLEASE HELP ME CAN YOU EXPLAIN ME A LITTLE MORE EXPECIFIC THE ACTIVE VOICE ,I PRECIATE IT.=)

[CrOtALiTo]

I'm not native English, but the second choice is the most formal than the first one.


But at least we leave that another mater explain us it more minutely.

Well, surely I'm the last person who should do it. Maybe I'm wrong, but I'll try to help. If you translated these sentences into Spanish, you could see it:

Las calles están siendo contaminadas por personas que tiran...

Then I transform into active voice:

Las personas (que tiran...) están contaminando las calles...

And later, I translate it into English:

Persons that throw (...) are polluting the streets.

So, present continuous active - present continuous passive

And present perfect active - present perfect passive

But that "due to" doesn't allow me to go on, since I've always seen "by" (as in Spanish we use "por").

So, wait until somebody corrects me

This is impossible. A verb has 5 attributes

1) Person (1,2,3)
2) Number (singular / plural)
3) Voice (Active, Passive, [Middle ])
4) Tense (Present, Perfect, Future, etc.
5) Mood (Indicative, Subjunctive, Imperative...etc)

The TENSE of the verb cannot be Present and Perfect, but a verb can be any combination of the 5 attributes, although some combinations never occur.

You can combine Present tense with Passive voice:
The dinner is being cooked.
You can combine Perfect tense with Passive voice:
The dinner has been cooked.
You can combine Present tense with Active voice
The cat sits on the mat.
You can combine Perfect tense with Active voice
The cat has sat on the mat.

All of these have indicative mood, 3rd person, singular.

Is this of any use?

I think that Lee ying wants to transform passive voice into active, observing the rules of the tenses.

Ah - ok

THE STREETS HAVE BEEN POLLUTED DUE TO PEOPLE THROW THEIR TRASH IN EVERYWEHRE

People have thrown their trash everywhere and have polluted the streets.



THE STREETS ARE BEING POLLUTED BY PERSONS THAT TRHOW THEIR TRASH ON THE FLOOR.

People are throwing their trash on the ground, and are polluting the streets.

ground = outside the house
floor = inside the house

This is not the passive voice, it is already active. It does not really make any sense.

You can't say present perfect. A verb is either present or perfect.

The sentence above is perfect passive.

The preparation of HOT DOG’S CARS has caused several illnesses.

I disagree. The present perfect tense is a very common tense in the English language.
"I have finished," "we have gone," and "John has eaten" are all examples of the present perfect tense. It is formed by using a present tense conjugation of the helping verb (auxiliary verb) have and the past participle.

The past perfect tense uses the past tense conjugation of the auxiliary and the past participle. For example:
I had finished
we had gone
John had eaten

The future perfect is similarly formed:
I will have finished
we will have gone
John will have eaten

The present perfect passive just throws been to the mix.
For example:
We have been given
Jill has been seen

The past perfect passive:
You had been given
Jack had been seen

The future perfect passive:
I will have been given
John will have been seen

Ah - OK it is just a difference in naming tenses: What you call the present perfect is for me simply the perfect tense. What you call the past perfect is what I call the pluperfect. We agree about the future tenses.

Yours must be an American convention, because my notation agrees closely with other European languages.

So my explanations above must be totally incomprehensible on that side of the Atlantic.

I'll leave Lee Ying to you.
