Passive Voice (Unit 15)

I want to know the difference between simple present tense with present perfect tense and when do we use them.

[size=150]The difference between them as follows:
= Use present tense: to show that something is done habitually e.g every day …etc
for example: Somebody cleans this room every day. (active)
[color=blue]This room is cleaned every day. (passive)

= Use present perfect: to show that something has been done before this moment.
for example: The room looks nice. Somebody has cleaned it. (active)
[color=blue]The room looks nice. It has been cleaned.

[color=darkblue]follow these rules to form :
[/size]
[size=150]( present tense) : Object + is/ are / am + verb (p.p)
( present perfect tense): Object + has / have + v (p.p)[/size]
With my best wishes.

ali close window .

Window is closed by Ali

[size=150]My friend Rifat…,
Your sentence must be written like this:
= Ali clos[color=blue]es the window. as a " Present active" sentence and to change it to ā€œpassiveā€ it must be changed like this
= The window is closed( [color=blue]by Ali ).

The subject ( [color=blue]by Ali ) in passive sentences is not necessary to be mentioned , because this target structure is based upon not knowing
the subject, unless if we want to show " who has done the verb." Or in other words the importance of the subject.[/size]

Hi !
I want to ask you what is the difference between meanings of these two sentences:
A pizza is eaten by me. (It was taken from Beeesneees
answer above on page 5)
And
A pizza has been eaten by me.

is - It is happening now.
has been - it happened in the past and I have recently stopped eating it.

And one more question. What distinguishes this two sentences :
I was being treated as …
And
I was treated as…
May I ask you to clarify for me using word ā€œbeingā€ ?

ā€˜Being’ here is the participle of the verb ā€˜be’. To me, it emphasises the continuous nature of the act.

Without additional context, the difference is small, though. The majority of native English speakers use them as interchangeable options unless the greater context means that one would be more appropriate than the other.

Hi Yankee

Thanks for your contribution. Just a word of warning: you won’t find that the Present Perfect,the Past perfect and the Future Perfect continuous passive forms are really used in practice. The future perfect would be: will have been written and of course don’t forget the present perfect: has been written.

thank you so much, this very handy

i don’t understand what is the meaning of (Mike has written a letter)? what does it means?
is my guestion write?

Your question would be better written like one of these:

Please can someone tell me the meaning of ā€˜Mike has written a letter’. Thank you.
I don’t understand the meaning of ā€˜Mike has written a letter’. What does it mean, please?
What is the meaning of ā€˜Mike has written a letter’, please?

Which part of the sentence are you having difficulty with? Is it the tense ā€˜has written’? This is the simple present perfect form of ā€˜to write’ and it indicates that the letter was written at an unspecified time in the past.

Dear Torsten,
I hope your doing well.

Excellent!
The way you have explained passive voice is awesome! Very easy and interesting.
Thank you very much!

I have a question about ā€œpassive voiceā€

[color=blue]Those girls confuse him. (active voice)
[color=brown]He is confused by those girls. (passive voice)

[color=blue]Those girls excite him. (active voice)
[color=brown]He is excited by those girls. (passive voice)

The question is about ā€œ[color=red]passive voiceā€ and ā€œ[color=red]participial adjectivesā€ (the past participial form of a verb used as an adjective)
It seems to me that these are the same thing.

So, are these sentences BOTH passive voice and also participial adjectives?

Does it depend on what verb is used?

[color=blue]Those girls love him. (active voice)
[color=brown]He is loved by those girls. (passive voice) — is this still a participial adjective? The grammar is the same as the other sentences.

I think that the [color=red]passive voice sentences always include [color=red]participial adjectives.
