English for Academic Purposes (EAP) demands a high degree of linguistic precision and formality. Unlike conversational English, where meaning is often negotiated through context and intonation, academic writing relies heavily on grammatical accuracy to convey complex arguments, research findings, and theoretical frameworks. Among the various grammatical components, verbs act as the engine of the sentence, driving the action and establishing the timeline of events. Consequently, errors in verb forms can significantly impair the clarity and credibility of a scholars work.
This guide examines the most prevalent verb form errors encountered in EAP writing. By understanding these pitfalls, writers can enhance the readability of their manuscripts and adhere to the rigorous standards expected by the academic community.
One of the most fundamental errors in academic writing is the lack of agreement between the subject and the verb. In English, a singular subject requires a singular verb form, while a plural subject requires a plural verb. While this rule seems straightforward, it becomes complicated by the presence of intervening phrases, collective nouns, and indefinite pronouns.
A common issue arises when a prepositional phrase separates the subject from the verb. Writers often mistakenly make the verb agree with the noun closest to it rather than the actual subject.
In the example above, the subject is "level" (singular), not "pollutants" (plural). Therefore, the verb must be "indicates."
Additionally, indefinite pronouns such as each, every, either, neither, everyone, and nobody are grammatically singular and require singular verbs, even when they refer to a group of people.
Maintaining consistent verb tense is crucial for establishing a logical timeline in academic texts. Unnecessary shifting between tenses can confuse the reader about when an action occurred. Different sections of an academic paper often adhere to specific tense conventions.
The Literature Review typically uses the present simple tense to discuss established knowledge or general truths, and the past simple tense to describe specific studies conducted in the past.
The Methods and Results sections generally require the past simple tense, as they describe procedures and outcomes that have already been completed. Conversely, the Discussion section often shifts back to the present to interpret the results and explain their significance.
A specific error related to tense is the overuse of the present perfect ("has shown") where the simple past ("showed") is required. The present perfect connects the past to the present, which is less appropriate for reporting isolated historical events in a methodology section.
Passive voice is a staple of academic writing because it allows the writer to emphasize the recipient of the action rather than the actor (e.g., "The solution was heated" rather than "The researcher heated the solution"). However, errors in the formation of passive verbs are frequent.
The standard passive construction requires the auxiliary verb to be followed by a past participle. A common error is using the past tense verb form instead of the participle, or omitting the auxiliary verb entirely.
Furthermore, irregular verbs often cause confusion in passive constructions. Writers may mistakenly use the base form or the simple past form rather than the past participle.
Academic writing requires a cautious approach to claims. Modals such as can, could, may, might, should, and must are essential for "hedging"softening claims to avoid sounding dogmatic. However, EAP writers often struggle with the grammar surrounding these verbs.
A primary error involves adding "to" after modal verbs, which structurally resembles semi-modals like "have to" or "need to," but is grammatically incorrect for pure modals.
Additionally, errors occur in the formation of negative and past modals. For example, the past form of "must" indicating obligation is "had to," not "musted," while the past form of "can" indicating ability is "could."
In EAP writing, particularly in discussing hypothetical scenarios or implications for future research, conditional sentences are frequently employed. The "mixed conditional" or "third conditional" structures are often prone to verb form errors.
The third conditional is used to describe a past situation that did not happen. It requires the structure: If + Past Perfect, would have + Past Participle.
Confusing the conditional forms can alter the timeline and meaning of the argument, leading to misinterpretation of the research limitations.
Mastery of verb forms is a non-negotiable aspect of successful EAP writing. From the foundational rules of subject-verb agreement to the nuances of passive voice and conditional structures, these grammatical tools enable writers to articulate their research with precision and authority. By systematically proofreading for these common errors and understanding the underlying tense conventions of academic papers, writers can significantly improve the quality and impact of their scholarly communication.
