ACT English: Maintain Consistent Formality and Tone

Marker 1: Contractions (don't, can't, it's) signal informal tone. Formal writing spells them out (do not, cannot, it is). Marker 2: Slang or colloquial phrases (cool, super, totally) are casual; formal writing uses standard vocabulary. Marker 3: Sentence length. Short, punchy sentences feel casual; long, complex sentences feel formal. Marker 4: Personal pronouns (I, we, you directly) feel informal; passive constructions feel formal. Marker 5: Exclamation points signal enthusiasm or informality; periods feel neutral or formal. A single switch in formality signals either a mistake or an intentional shift in the author's voice.

Example: "The study shows that results were incredibly surprising!" vs. "The study indicates results were surprising." The first is informal; the second is formal. On ACT English, consistency matters unless the context requires a shift (like a quoted informal speaker within a formal essay).

Error 1: Mixing "the researcher discovered" with "you'll find out." Inconsistent pronouns and formality. Error 2: Starting formal, then inserting "but hey, this is cool!" Abrupt tone shift. Error 3: Using "don't" in formal writing or spelling it "do not" in casual writing. Error 4: Shifting from active voice (formal) to passive voice mid-sentence without reason. On ACT English, assume the established tone is correct and flag any deviation as an error.

Strategy: Reread the passage's opening. Determine if it's formal or casual. Then check each sentence against that baseline. If a sentence contradicts the tone, flag it for correction.

Passage excerpt: "The scientific community has conducted extensive research on climate change. Studies indicate that human activity plays a significant role. We totally think this is a big deal." Identify the problem: "totally" is too casual for the formal tone of the previous sentences. Fix: "We recognize this as a significant concern" or similar. The shift to "totally" and "big deal" breaks the professional register.

Try finding three tone inconsistencies in your next practice passage. Mark them and rewrite for consistency. This exercise trains your ear to notice tonal shifts quickly.

ACT English tests tone consistency because professional and academic writing demands a stable voice. Employers and college professors expect writers to maintain register. Tone consistency questions account for 5-10% of English questions, and most test-takers miss them because they don't read for voice.

This week, read two academic articles and note the tone. Then read a blog post and compare. By test day, you'll easily spot when ACT passages veer off tone, and you'll earn quick points on consistency questions.
