Welcome to the World of Active-Only Verbs!
In your English lessons, you have probably learned how to flip sentences around to create the passive voice (for example: "The chef cooked the meal" becomes "The meal was cooked by the chef"). It feels like a magic trick, right?
But here is a secret: Not every verb can do this trick. Some verbs are "active-only" stars—they simply do not work in the passive voice. Understanding which verbs these are will help you write more accurately in your essays and science reports. Don’t worry if this seems tricky at first; by the end of these notes, you’ll be an expert at spotting them!
1. The Golden Rule: Intransitive Verbs
To make a sentence passive, the verb needs an object (someone or something receiving the action). Think of it like a game of catch: you need a thrower and a catcher. If there is no "catcher" (object), you cannot make the sentence passive.
Verbs that do not have an object are called Intransitive Verbs. These verbs describe actions that stay with the "doer."
Common "Active-Only" Action Verbs:
Happen / Occur: "The accident happened yesterday." (Correct)
"The accident was happened..." (Incorrect!)
Rise / Fall: "The sun rises in the east." (Correct)
"The sun is risen by..." (Incorrect!)
Arrive / Go / Come: "The bus arrived late." (Correct)
"The bus was arrived..." (Incorrect!)
Analogy Time!
Imagine a one-way street. Intransitive verbs are like cars on that street. They can only go forward (Active). They don't have enough space to turn around and go the other way (Passive)!
Quick Review: If you can't ask "Who?" or "What?" after the verb, it’s probably intransitive and cannot be passive.
Example: "He slept." (He slept what? Nothing!) -> No passive voice possible.
2. Verbs of "Being" and "State"
Some verbs don't describe a physical action; they describe a state or a relationship. Even if they have something that looks like an object, they still cannot be used in the passive voice.
The Most Important Ones:
- Have (meaning possession): We say "I have a bicycle," but we never say "A bicycle is had by me."
- Belong to: "This book belongs to Sarah." (We don't say "Sarah is belonged to by the book.")
- Resemble: "He resembles his father." (We don't say "The father is resembled by him.")
- Suit / Fit: "That shirt suits you." (We don't say "You are suited by that shirt.")
3. Academic "Must-Knows" (Language Across the Curriculum)
When you are writing for Science or Geography (what we call Language across the Curriculum), you will often use the verb Consist of. This is a very common trap for students!
The Verb: Consist of
Active: "The mixture consists of water and salt."
Passive: "The mixture is consisted of..." (BIG MISTAKE!)
Did you know? Even though "consist of" describes what is inside something, it acts like an intransitive verb. It never takes the passive form. Always keep it active!
4. How to Avoid Common Mistakes
Struggling with these? Here is a simple "Passive Proof" check you can use:
- Find the Subject (the doer).
- Find the Verb (the action).
- Find the Object (the receiver).
If you cannot find a receiver, or if the verb is about owning something, keep it Active!
Common Error Alert!
"The earthquake was occurred in 1999." -> Wrong!
"The earthquake occurred in 1999." -> Correct!
5. Key Takeaways Summary
1. No Object = No Passive: Verbs like happen, arrive, die, and sleep are active-only.
2. Possession is Active: Verbs like have, belong, and resemble stay active.
3. Science Alert: Always use "consists of" in the active voice.
4. Use Your Ears: Often, a passive version of these verbs will just "sound wrong" because we never hear native speakers use them that way!
Encouragement Corner
Don't worry if you find this a bit confusing at first. English has a lot of "rules," but the more you read and write, the more these "active-only" verbs will become natural to you. You're doing a great job—keep practicing!
