Passive verbs in English are always formed using the appropriate form of the verb "be" and a perfect participle.
The wine was drunk by my guests before I even arrived.
"Was" is a form of the verb "be" and "drunk" is the perfect participle of "drink."
Sometimes the form of the verb "be" is itself in the form of a participle plus an auxiliary.
The wine ...
"I work after I get paid" cannot be changed into passive without the verb "work" having an object.
And then you somehow changed it into passive:- "A work is done after I get paid." How can you change the verb "work" into a noun while changing it into passive?
It should be like :- "I'm paid beforehand" or simply "I'm paid in advance".
You misunderstand how the passive voice works.
In an active sentence with a subject and an object
I eat the cheese.
The cheese is eaten (by me)
But an active clause which has no object cannot be changed to passive.
I work. (There is no passive equivalent)
You can change the verb, for example
I do the work-> The work is done (...
Since it's a short incorrect sentence, it's not obvious what the the speaker meant, and one can't point to just a single error in its construction.
As noted in the comment, "quarantine" is a transitive verb, so it can be passivized. It is also a noun. Here are two examples of correct use of the word that may be what the speaker intended:
1 How many days ...
Although "bent" is the past tense of "bend", it can also be an adjective because it describes a static position. If you bend (verb) a piece of metal, then it is bent (adjective). It can also be a verb, for example "I have bent the metal".
If you spend the day "bending over" that would mean that you were constantly bending, then standing up straight, then ...
I don't think that passive voice is the primary problem with the sentence.
The verb should be "were provided" not "was provided" ("results" is plural).
"The simulation results of the winglet" sounds awkward. It would be better to say "The results of the winglet simulation" or "The winglet simulation results".
The sentence feels like it needs more ...
The usual place for an adverb like still is after the first auxiliary verb, so your feeling is correct.
However, adverbs can go in many places, and right before the verb phrase is also OK, if perhaps not as common.
Probably this is about the necessities for making tests rather than English grammar. If the test constructor hadn't put the still before the ...
In the passive voice, the subject becomes "the assignment". Since this is singular (and not special, like "you"), the correct form of "have" is "has", so it should be:
The assignment has been completed by you.
This sentence is technically not correct, but the error is one which I think most people wouldn't really notice that much, and the meaning is still quite clear. This sort of thing often happens in technical contexts because there is so much jargon and some words have different meanings than their usual ones that things can sometimes seem correct even when ...
The first two of these posts reflects a fundamental ignorance of some English grammar and syntax rules. What makes an English tense passive is using some form of the verb "to be" as an auxiliary verb preceding the main verb, except for the English progressive tenses (I am/was seeing you). This insertion is done to turn the subject of any sentence into the ...
This is actually a trickier question than it seems at first (and it actually took me a little bit of time to figure out what I think is the technically right answer to this). This use of "to be" is something that native English speakers are all pretty much familiar with, but does not seem to be discussed much in textbooks, etc.
This is actually a form of ...
First, I should point out that the first sentence is an abbreviated form of "testing is complete". This kind of abbreviated form is used in newspaper headlinese, notices and computer status displays.
As an adjective, complete means whole, so the following sentence means that all of the pieces of testing have been put together... probably not what you meant.
Yes, it is passive. Consider an active form:
"Landlords and tenants often disagree over paying for someone to mend things".
Since the focus isn't on who will do the mending, it makes sense to make it passive.
No, we don't need to. Both versions are OK, I think, although I would prefer the original. If we say be fully cooked we are describing the (end) state of the turkey, whereas fully cook focuses on the process of cooking.
It is acceptable to use the verb cook intransitively, that is "the turkey cooks", rather than "the oven cooks the turkey". Likewise we ...
The "had broken" form may have a different meaning to the "had been broken." It depends on the rest of the story.
What would have happened if the bridge had broken while we were crossing it?
This means that the person is concerned for the possibility the bridge might have failed when he was on it. Maybe the story is about some rickety rope-and-plank ...
"Break" has both a transitive and intransitive meaning.
My computer broke while I was trying to write my paper
is perfectly idiomatic and grammatical.
We tend to use the verb transitively when the cause of the breakage is known. We tend to use the verb intransitively when the cause is unknown.
It is, however, odd to use "break" with something as ...
