Milk is used for making butter .(voice change)
Answers
The correct passive of the given sentence is given below:
It is known that milk is used for making butter.
Explanation
This is a special passive structure. We can use this structure when we cannot say or do not need to say who the speaker is. Here is the list of verbs that can be used in this structure: agree, allege, announce, assure, believe, consider, decide expect, explain, hope, know, report, say, suggest, suppose, think, understand
Answer:
Passive voice: "Milk is used for making butter."
Active voice makes the subject "do" something:
- Active voice 1: "Butter comes from milk."
- Active voice 2: "People make butter from milk."
- Active voice 3: "Churning milk separates butterfat from buttermilk, creating butter."
A linking verb makes the subject "be" something:
- Linking verb: "Butter is a milk product." (The verb *is* makes the subject, butter, "be" a milk product).
Explanation:
First, the exercise is pointless because passive voice is justifiable and correct in this instance, though there is another problem with it that makes it seem strange to a native English speaker. Just know that any effort to eliminate passive voice when passive voice is desirable leads to awkwardly distracting sentence constructions (as many of your responders seem to demonstrate).
Rule of thumb: It is not necessary nor desirable to avoid passive voice when the agent of the action is ridiculously obvious or completely beside the point. "He was arrested for burglary" does *not* generally benefit in any way by rewriting it as active voice, stating that law enforcement officers arrested him (Duh! This insults the reader's intelligence). Likewise, we do not *care* who churns butter to make milk. That's simply how butter "is made" (passive voice, and just fine and dandy that way). Going out of our way to avoid passive voice in this case -- JUST to avoid passive voice -- is a misunderstanding of English grammar.
However, if you simply wish to present a challenge or just wanted to illustrate the difference between passive and active voice, all you need to do is recast it as having a subject that *does* the verb, rather than have a subject that has a verb "done to it."
Alternatively, you could also use a linking verb. Linking verbs (based on forms of *is*) are sometimes confused for passive voice constructions. But forms of is make statements of "being" rather than "action."
In short, passive voice means there is a subject having something done to it. To eliminate passive voice constructions, choose a subject that is doing something (action verb) or being something (linking verb).
My examples demonstrate both.
(Passive voice means the "agent of the action" -- i.e., who is "using" -- isn't the subject of the sentence and isn't even known. On the other hand, active voice characteristically distinguishes itself with a subject *doing* the verb. The subject either "verbs" or "verbs an object."
But again, rewriting the sentence to eliminate passive voice wasn't necessary. The sentence is weakly constructed for a different reason.
