Analyzing Sentence Improvement for "had been hijacked"

The question asks us to examine the bracketed part of the sentence, "(had been hijacked)", and determine if it needs improvement from the given options. The sentence is: "The footpath (had been hijacked) by gigantic blue-and-green barricades."

Understanding the Original Phrase: "had been hijacked"

The phrase "had been hijacked" is in the past perfect passive tense. Let's break this down:

• Tense: Past Perfect (had + past participle)
• Voice: Passive (be + past participle, with the subject receiving the action and the doer often introduced by "by")
• Meaning: This tense and voice indicate an action that was completed by the barricades at some point before another past event or time, with the footpath being the recipient of the action (being hijacked).

The sentence structure "The footpath... by gigantic blue-and-green barricades" clearly indicates that the footpath is the object receiving the action (hijacked), and the barricades are the agents performing the action. This aligns perfectly with the passive voice.

Evaluating the Improvement Options

Let's look at the provided alternatives:

1. <p>have been hijacked</p>
   • This is the present perfect passive tense.
   • It indicates an action that started in the past and continues to the present, or an action that happened in the past with a result relevant to the present.
   • While grammatically correct, using the present perfect might change the meaning compared to the original past perfect, implying a current state or recent completion with present relevance. The original sentence uses past perfect, suggesting completion before another past point.
2. <p>have being hijacked</p>
   • This option is grammatically incorrect.
   • The passive voice structure with "have" or "had" requires "been" followed by the past participle, not "being".
3. <p>had been hijacking</p>
   • This is the past perfect continuous tense in the active voice.
   • It would mean the footpath was actively performing the action of "hijacking" continuously up to a point in the past.
   • This completely changes the meaning and is incorrect because the footpath is the recipient, not the doer, of the action.
4. <p>no improvement</p>
   • This option suggests that the original phrase "had been hijacked" is correct and fits the sentence.
   • As analyzed earlier, "had been hijacked" is a correct grammatical construction (past perfect passive) and makes sense in the context of the sentence, where the footpath is acted upon by the barricades.

Conclusion on Sentence Improvement

Comparing the options, only the original phrase "had been hijacked" and "have been hijacked" are grammatically correct passive constructions. However, the original uses the past perfect, which is a valid tense to describe a past action completed before another past point. The provided context doesn't necessitate a change to the present perfect. Options 2 and 3 are grammatically incorrect or change the meaning entirely.

Therefore, the original sentence using "had been hijacked" is grammatically sound and likely conveys the intended meaning. No improvement is necessary.

Additional Information on Passive Voice and Past Perfect

Understanding the passive voice and the past perfect tense is crucial for sentence improvement exercises like this. Let's briefly recap:

• Passive Voice: Used when the focus is on the action and the recipient of the action, rather than the performer of the action. The structure is typically subject + form of "be" + past participle + (optional) "by" + doer. Example: The ball was kicked (by the player).
• Past Perfect Tense: Used to talk about an action that was completed before another action or point in the past. The structure is "had" + past participle. Example: She had finished her homework before the movie started.
• Past Perfect Passive: Combines these two. Structure: subject + had + been + past participle + (optional) "by" + doer. Example: The letter had been sent before he called.

In the sentence "The footpath had been hijacked by gigantic blue-and-green barricades," the footpath is the subject, "had been hijacked" is the past perfect passive verb phrase, and "by gigantic blue-and-green barricades" indicates the agent performing the action. This structure is correct and effectively conveys that the barricades completed the act of taking over the footpath at some prior point in time.
