Grammar C1 - Causative and Impersonal Reporting

Boundary Overview

The Rule: At the C1 level, English expands beyond simple active/passive diathesis into sophisticated syntactic mechanisms that manipulate agency, evidentiality, and thematic packaging:

  • The Causative Framework (have / get + Object + V3 & have / get / make / let + Agent + Verb): Governs delegated action, professional commissioning, and experiential misfortune. Instead of executing an action directly, the grammatical subject initiates, arranges, compels, permits, or undergoes an event realized by an external agent.
  • The Impersonal Passive (It + be + V3 + that-clause): Establishes an evidential safety barrier in academic, journalistic, and legal discourse. By deploying dummy preparatory it, the writer reports unverified assertions, institutional consensus, or widespread beliefs without assuming personal authorship of the claim or assigning legal liability.
  • The Personal Reporting Passive (Subject + be + V3 + Infinitive Matrix): Fronts the topical entity of the subordinate clause to matrix subject position. This structural transformation achieves tighter thematic cohesion while encoding intricate temporal and aspectual relationships through simple, continuous, perfect, and passive infinitive matrices.

⚖️ Discrimination Map (Structural Boundaries & Functions)

Zone 1: The Passive Causative Matrix (have / get + Object + V3) — Commission vs. Adversative Misfortune

Zone 2: Active Causatives & Hierarchy of Agency (make, have, let, get)

Zone 3: Impersonal Reporting Passives (It + be + V3 + that-clause) — The Evidential Safety Barrier

Zone 4: Personal Reporting Passives (Subject + be + V3 + Infinitive Matrix) — Thematic Prominence & Aspectual Shifts

Zone 5: Existential Transformations (There is / are said to be...) & Stylistic Traps


🎴 Interactive Web Practice (Comprehension Check)

Question 1 (Causative Word Order & Adversative Meaning): Analyze the morphological and semantic differences between these two sentences: (a) "The asset manager had liquidated the high-yield bond portfolio." versus (b) "The asset manager had the high-yield bond portfolio liquidated." Furthermore, how does sentence (b) change if the context is an external market catastrophe rather than a deliberate strategy?
Answer: Sentence (a) represents a finite Past Perfect Active construction, whereas sentence (b) represents a Passive Causative construction.

Explanation: In sentence (a), the past participle liquidated immediately follows the auxiliary had (`had + V3 + Object`). This indicates that the asset manager personally and directly executed the liquidation in the past.

In sentence (b), the object noun phrase the high-yield bond portfolio intervenes between the causative verb had and the past participle liquidated (`had + Object + V3`). In a standard strategic scenario, this denotes an arranged/commissioned service—the asset manager ordered brokers or custodians to carry out the liquidation.

If framed within an unexpected market crisis, sentence (b) functions as an adversative/experiential causative, meaning the asset manager suffered or underwent the forced liquidation of the portfolio due to external margin calls or regulatory intervention, completely devoid of intentional agency.

Question 2 (Personal Passive Transformation & Aspectual Anteriority): Convert the following impersonal report into a Personal Reporting Passive: "It is widely believed that the rogue trading syndicate laundered over five hundred million dollars through shell corporations during the 2024 fiscal cycle." Why is a simple infinitive ("to launder") syntactically and chronologically invalid?
Answer: "The rogue trading syndicate is widely believed to have laundered over five hundred million dollars through shell corporations during the 2024 fiscal cycle."

Explanation: To transform this into a personal passive, the subordinate subject (the rogue trading syndicate) is promoted to matrix subject position, agreeing with the singular present auxiliary is and the passive participle widely believed.

Because the belief exists in the present (is believed), but the laundering event occurred anteriorly in the past (laundered during the 2024 fiscal cycle), standard syntax demands a Perfect Infinitive (to have + V3: to have laundered). Using a simple infinitive ("is believed to launder") would distort the chronology, incorrectly indicating an ongoing, habitual present action or a future intention rather than a completed historical occurrence.

Question 3 (Existential Passive Shift & Auxiliary Agreement): Transform the following impersonal sentence into an Existential Reporting Passive starting with There: "It is reported that there are significant cybersecurity vulnerabilities in the municipal power grid." Explicitly explain what governs the grammatical number of the auxiliary verb.
Answer: "There are reported to be significant cybersecurity vulnerabilities in the municipal power grid."

Explanation: In this transformation, dummy there is fronted to the matrix subject position. The subordinate copular predicate are collapses into the infinitive to be.

Crucially, although there occupies the structural subject slot, it has no intrinsic grammatical number. Therefore, agreement on the finite auxiliary verb (are reported vs. is reported) is governed by the postponed logical subject (significant cybersecurity vulnerabilities). Because the logical subject is plural, the matrix auxiliary must inflect as the plural are.

Question 4 (Active Causative Passivization & Morphological Shifts): Transform the active causative sentence "Antitrust regulators made the technology conglomerate divest three of its cloud infrastructure subsidiaries" into the passive voice. What crucial morphological change occurs to the dependent verb?
Answer: "The technology conglomerate was made to divest three of its cloud infrastructure subsidiaries by antitrust regulators."

Explanation: In active causative constructions governed by make, the complement verb appears strictly as a bare infinitive without to (made the conglomerate divest).

However, when the construction is passivized, English historical syntax obligatorily reinstates the full to-infinitive (was made to divest). Omitting the infinitive particle to in the passive (❌ "The conglomerate was made divest...") is a severe grammatical error at the C1 level.

Applied Practice Tasks

Practice 1 (Personal Passive & Perfect Continuous Infinitive): It is understood that the pharmaceutical laboratory ______ (negotiate) licensing terms with overseas partners for the past eighteen months.
Answer: is understood to have been negotiating

Explanation: The reporting matrix is in the present simple (is understood), while the reported negotiation represents an extended progressive action stretching across the past into the present. We use the personal passive with the perfect continuous infinitive to have been negotiating.

Practice 2 (Existential Personal Passive Agreement): There ______ (estimate / be) approximately two million undiscovered marine species in deep ocean trenches.
Answer: are estimated to be

Explanation: The postponed logical subject approximately two million undiscovered marine species is plural; consequently, the auxiliary verb must agree in the plural form (are estimated to be).

Practice 3 (Passive Perfect Infinitive): The whistleblower is thought ______ (intimidate) by private security contractors prior to delivering her testimony.
Answer: to have been intimidated

Explanation: The action occurred prior to the present belief (requiring perfect aspect) and the subject was the victim/receiver of the intimidation (requiring passive voice). We employ the passive perfect infinitive to have been intimidated.

Practice 4 (Passive Causative - Commission): The chief executive ______ (her keynote address / translate) into Mandarin and Japanese before the international trade symposium opened.
Answer: had her keynote address translated (or: got her keynote address translated)

Explanation: Demonstrates an arranged professional service using the past simple causative frame had + Object + Past Participle (had her keynote address translated).

Practice 5 (Active Causative with Persuasion): After intense cross-examination, the defense counsel finally managed to get the star witness ______ (admit) the discrepancy in her alibi.
Answer: to admit

Explanation: While active make, have, and let govern bare infinitives, causative get strictly requires the full to-infinitive when inducing or persuading an agent (get someone to admit).

📊 Quick-Reference Table

Construction Type Canonical Syntactic Formula Temporal & Aspectual Value Evidential & Discourse Function Transformation Pair High-Frequency Pitfall
Passive Causative (Service) Subject + have/get + Object + V3 Flexible (governed by auxiliary tense) Arranging or paying for a third party / professional to execute an action "The firm had the software debugged by external engineers." Misplacing participle before object (had debugged the software = past perfect active)
Passive Causative (Adversative) Subject + have/get + Object + V3 Flexible (typically past completed) Undergoing an unintentional, negative, or catastrophic incident "The embassy had its communications intercepted." Assuming the subject intentionally instigated the action
Active Causative (make) Subject + make + Agent + V1 Governed by matrix tense Enforcing mandatory compliance, coercion, or necessity Active: "They made him testify."
Passive: "He was made to testify."
Using to in the active (made him to testify ❌) or dropping to in passive (was made testify ❌)
Active Causative (get) Subject + get + Agent + to + V1 Governed by matrix tense Persuading, incentivizing, or coaxing an agent to act "We got the client to approve the expanded budget." Dropping the required particle to (❌ got the client approve)
Impersonal Passive It + be + V3 + that-clause Matrix reflects reporting time; clause reflects event time Institutional distancing; evidential safety barrier against libel; collective consensus "It is hypothesized that the asset bubble will deflate gradually." Inserting human agents inappropriately into dummy It slots
Personal Passive (Simple Inf.) Subject + be + V3 + to + V1 Event is concurrent with reporting moment or oriented to future Fronts topical entity; provides thematic continuity across sentences "The pipeline is projected to open next December." Using simple infinitive for anterior/completed past events
Personal Passive (Continuous Inf.) Subject + be + V3 + to be + V-ing Event is unfolding progressively at the reporting moment Highlights ongoing active developments concerning the topical subject "The diplomat is reported to be drafting a ceasefire treaty." Confusing simple infinitive (to draft) with ongoing progressive (to be drafting)
Personal Passive (Perfect Inf.) Subject + be + V3 + to have + V3 Event completed anteriorly prior to the reporting moment Encodes historical anteriority while keeping reporting stance in the present "The treasurer is rumored to have fled the country." Dropping auxiliary have (❌ is rumored to flee distorts historical time)
Personal Passive (Perfect Passive) Subject + be + V3 + to have been + V3 Event completed anteriorly; raised subject is patient Expresses anterior passive experience undergone by the topical entity "The artifacts are believed to have been stolen in 1944." Omitting participle been (❌ to have stolen changes voice to active)
Existential Reporting Passive There + be + V3 + to be + Noun Phrase Matrix matches reporting time; agrees with logical subject Reports existence or presence of phenomena without personal attribution "There are estimated to be over forty variants of the pathogen." Failing number agreement on matrix auxiliary (❌ There is estimated to be many variants)
