Sentence Structure and Formation
This ACT English topic asks two things first: is the sentence complete, and does its structure show the relationship between ideas clearly?
核心知识
Strip the sentence down to subject, verb, and clause boundaries. Then choose the version that keeps the sentence complete, keeps modifiers and references attached to the right words, and shows whether ideas are equal, dependent, or sequential.
深入理解
Rule: ACT tests this topic through fragments, run-ons, agreement, modifier placement, pronoun reference, and clause-building. The surface wording changes, but the fix usually starts with the sentence backbone.
Cross out long interrupters if you need to. Once you can see the core clause, it becomes easier to spot a missing main verb, a bad clause join, or a phrase attached to the wrong noun.
When a sentence combines ideas, pay attention to hierarchy. A reason, condition, or time frame usually belongs in a subordinate clause. Two equal ideas can be coordinated.
