Identifying Grammatical Errors in English Sentences

Let's analyze the given sentence to find the segment that contains a grammatical error: "The little boy was run away from his mother."

The sentence describes an action performed by "The little boy". The action is "run away".

Analyzing the Verb Phrase: "was run away"

The phrase "run away" is a phrasal verb. In this context, it means to escape or flee from someone or something. The verb "run" in this sense is typically intransitive, meaning it does not take a direct object. For example, "He ran away."

The structure "was run" uses the past tense of the verb "to be" ("was") followed by the past participle of "run" ("run"). This structure is characteristic of the passive voice. However, the passive voice is generally used with transitive verbs, where the object of the action becomes the subject of the passive sentence. Since "run away" (meaning to flee) is intransitive, it cannot be correctly used in the passive voice in this way.

The subject, "The little boy", is the one performing the action of running away. Therefore, the sentence should be in the active voice.

The correct way to express this action in the past tense, active voice, is to use the simple past tense of the verb "run", which is "ran".

The correct sentence should be: "The little boy ran away from his mother."

Examining the Options for the Grammatical Error

Let's look at the provided segments:

• his mother: This is a prepositional phrase indicating where the boy ran away from. It is grammatically correct in this context.
• The little boy: This is the subject of the sentence and is grammatically correct.
• was run: This is the main verb phrase in the passive voice. As analyzed above, the intransitive phrasal verb "run away" is incorrectly used in the passive voice here. This segment contains the grammatical error.
• away from: This is part of the phrasal verb and the prepositional phrase. Individually, "away" and "from" are used correctly here in context. The error lies specifically in the auxiliary verb and the form of "run".

Summary of Grammatical Error Analysis

The segment "was run" is grammatically incorrect because the verb "run away" (meaning flee) is intransitive and should be used in the active voice ("ran away") when the subject is performing the action.

Conclusion on the Grammatical Error

Based on the analysis, the segment containing the grammatical error is "was run".

Additional Information: Active vs. Passive Voice and Intransitive Verbs

Understanding the difference between active and passive voice is crucial for identifying grammatical errors.

• Active Voice: The subject performs the action. Structure: Subject + Verb + (Object). Example: "The dog chased the ball." (The dog is the subject performing the action 'chased' on the object 'ball').
• Passive Voice: The subject receives the action. Structure: Object of active sentence becomes Subject + be (conjugated) + Past Participle of Verb + (by Subject of active sentence). Example: "The ball was chased by the dog." (The ball, the original object, is now the subject receiving the action 'was chased').

Intransitive verbs are verbs that do not take a direct object (e.g., arrive, go, sleep, run (in the sense of moving quickly), happen, smile, walk (when just referring to the act of walking)). Since there is no direct object to become the subject of a passive sentence, intransitive verbs generally cannot be used in the passive voice.

In the sentence "The little boy was run away from his mother," the verb "run away" means 'to flee', which is an intransitive use of 'run'. The boy is the one doing the fleeing. Therefore, it must be in the active voice: "The little boy ran away..."
