SAT reading study notes - Grammar

• Subject-Verb Agreement: the verb must agree with the true subject, not the nearest noun. “The group of students IS ready” (group is the subject).
• Pronoun-Antecedent Agreement: pronouns must agree with their antecedents in number and gender. Use “he or she” for singular gender-neutral antecedents.
• Comma Usage: commas separate items in a series, set off introductory clauses, and join independent clauses with a conjunction. Never use a comma alone to join two independent clauses.
• Semicolons: join two independent clauses without a conjunction. “It was late; we went home.” Also separate items in complex lists.
• Modifier Placement: modifiers should be placed next to the word they modify. Misplaced modifiers create ambiguity.
• Apostrophes: possessives use apostrophes (“the dog’s bone”); contractions use apostrophes (“it’s” = “it is”). Never use apostrophes for plurals.

Problem: “Running quickly, the finish line was reached.” Is this sentence correct?

Solution: Step 1: The participial phrase “Running quickly” should modify the subject performing the action Step 2: The subject is “the finish line” — a finish line cannot run Step 3: Correct: “Running quickly, the runner reached the finish line”

Problem: “The experiment failed, the team decided to start over.” Fix the error.

Solution: Step 1: “The experiment failed” is an independent clause Step 2: “the team decided to start over” is an independent clause Step 3: Two independent clauses joined by only a comma = comma splice Step 4: Fix: “The experiment failed**;** the team decided to start over” (semicolon) OR: “The experiment failed**, so** the team decided to start over” (comma + conjunction)

Problem: “Neither the students nor the teacher were aware of the change.” Is this correct?

Solution: Step 1: With “neither…nor,” the verb agrees with the nearer subject Step 2: “the teacher” is nearer and is singular Step 3: Correct: “Neither the students nor the teacher was aware of the change”

Key insight: “Neither…nor” and “either…or” follow proximity agreement — the verb matches the subject closest to it.

Grammar is the infrastructure of communication — like the electrical wiring in a house, you only notice it when something goes wrong. Subject-verb agreement is the matching of the subject to the verb, like making sure the key fits the lock. Pronoun reference is ensuring every “he” and “she” points to the right person — like labelling files so you can find them later. Modifier placement is about keeping related words together — a misplaced modifier is like putting the key to the front door in the kitchen drawer. The SAT tests whether you can spot these structural problems and fix them.

Subject-verb agreement across intervening phrases. The subject and verb must agree in number, even when prepositional phrases, relative clauses, or appositives separate them. For example, “The box of chocolates is on the table” uses “is” (singular) because “box” is the subject, not “chocolates.” Ignore intervening phrases when identifying the subject.

Comma splices joining independent clauses. Two independent clauses cannot be joined by only a comma; this creates a comma splice. Fix it by using a semicolon, a comma plus a coordinating conjunction (FANBOYS), or by making one clause a dependent clause. For example, “It was late, we went home” is a splice; “It was late, so we went home” is correct.

Misplaced modifiers changing meaning. A modifier should be placed next to the word it modifies. A misplaced modifier creates ambiguity or unintended meaning. For example, “Running quickly, the finish line was reached” implies the finish line was running. The corrected version is “Running quickly, the runner reached the finish line.”

• Comprehension — Grammar knowledge supports reading comprehension by clarifying sentence meaning and author intent.
• Writing Language — The writing and language section tests the same grammar concepts applied to editing and revising passages.
• Writing Essay — Correct grammar usage is essential for constructing clear and effective evidence-based essays.
