No apologies necessary, but thank you for looking into it. I suppose the accuracy of an automatic check means less to me than the answer and explanation. I was merely using it then as an example to point out so we were aware of what I was referencing.
I didn't know about the readability statistics myself, but the passive I do. I saw something that was unfamiliar to me (in the context of the passive), but it's resolved now—it wasn't the passive, although I suspected it to be.
Okay, when we're talking about whether a sentence is passive or active, we are talking about the
voice of the sentence. This term is unrelated to authorial voice; it's simply grammatical jargon. Voice affects the verb.
I suck at defining things satisfactorily, but the active voice occurs when the subject is not being acted upon by something. So okay, but what does "not being acted upon..." mean? Let's take examples because they're better illustrators (subject in bold, verb in italics):
[1]
A boy ran to a bookstore.
[2]
He is John.
[3]
The knight slew a dragon.
[4]
Sally's boyfriend gave her a book.
[5]
She made him kill that man.
Now, in these examples nothing is being done to the subject by something else. Getting into the nitty-gritty grammatical jargon, [1] has an intransitive verb, which can't take the passive; [2] has a copular verb, which also can't take a passive. [3] is a monotransitive verb, which can take the passive; likewise, [4] is a ditransitive verb, which also can take the passive (note a transitive verb is a verb that takes an object; many verbs can be either transitive or intransitive). [5] is complex transitive verb, meaning it takes an object and an object complement.
Essentially, on the question, "can this type of verb take a passive?":
Intransitive: No
Copular: No
(Mono-/Di-/Complex) transitive: Yes
Additionally, the examples illustrate the dynamic {1, 3-5}/static {2} verb divide which is the monkey wrench in defining the active voice because a subject doesn't have to be acting to be active and can be acted upon
by the verb as well. For example,
[6]
The car blew up.
Something is happening to the subject, sure; the verb is stating what's happening to the subject, but is as active as my early morning runs.
"We" (honestly didn't want to use this word) can conclude that there is a requisite for the passive to (come into) exist(ence): it needs to have at least one object. Why is that?
I guess the best way to truly qualify the voice divide is to show the thesis and antithesis side by side (A=Active, P=Passive):
[7A] Sam punched Ed.
[7P] Ed was punched by Sam.
[8A] Billy kicked the ball.
[8P] The ball got kicked by Billy.
[9A] Joe dropped the ball.
[9P] The ball was dropped by Joe.
[4A] Sally's boyfriend gave her a book.
[4P1] Sally was given a book by her boyfriend.
[4P2] A book was given to Sally by her boyfriend.
[5A] She made him kill that man.
[5P] He was made to kill that man by her.
What can be gathered from those examples, well, the passive versions turns the object into the subject and turns the subject into an object of a preposition, called in this case an
agential by-phrase, which is a completely optional element. [4] has two passive sentences because it has two objects and can choose which to make a subject of the passive sentence. This ties back into that whole transitive verb thing—if you don't have an object, it can't be turned into a subject of a passive sentence. Usually, the by-phrase and an [auxiliary verb + a past participle] (<-a verb phrase) together are good indicators of the passive voice.
Back to the optionality of the by-phrase and the past participle. Past participles can also act as adjectives as well, so when the by-phrase is omitted, it can be particularly nebulous as to whether the there's an adjective modifying the subject or passive verb phrase:
[10?] The house was haunted.
This is ambiguous. Something could be haunting it, or it could just be a predicate adjective defining the houses's state. It's best to say could be a passive verb or an adjective, although sometimes it can be plain as to which it could be. Altered from
here.
Even further still is that past participial phrases are inherently passive (because most of them can be expanded into a relative clause with passive verb phrase) but perform adjectival roles:
[11] The storm summoned in rage wreaked havoc.
[11a] The storm that was summoned in rage wreaked havoc.
Although there is no by-phrase, I wouldn't consider summoned to be an adjective here. I created a similar sentence to [11a] in my word and it says that it is passive, despite the sentence's verb (predicate) is active just because there's a passive relative clause. I would say the relative clause is in the passive voice, but the sentence as a whole is in the active.
Next, a present participial phrase can also be passive:
[12] The newspapers being torn apart are an act of protest.
[13] False information being spread is detrimental to people.
Now, I've recently learned of something called the concealed passive which uses the present participle passively. But I'm not getting into, and based on /my intuition/, it is rare, but I'm unable to substantiate that.
Like all other verbals, the infinitive too can take a passive form"
[14] He wanted /to be left/ alone by his parents.
[15] They desired /to be married/ on the twentieth.
Next on this never-ending ride, a verb in the progressive aspect (it's almost identical to a present participle) is not necessarily passive:
[16] He
was running.
[17] They
were riding their bicycles.
[18] We
were pulverizing those little shits.
But they can become passive as well, if they're transitive:
[16P] None. No passive.
[17P] The bicycles were being ridden (by them).
[18P] Those little shits were being pulverized (by us).
I think that handles the bulk of the passive and active voices. If you are confused about some things, you can ask me. If you don't know what some of the terms mean, I suggest reading Chapter 2 for objects, subject, etc.; Chapter 3c.i.
ff, Chapter 4b, because that's where you'll get immediate answers. If those are unacceptable/unsatisfactory, just ask.
