Language Use and Conventions
Readers reward prose that is controlled, precise, and appropriately formal because clear language makes the argument easier to trust.
核心知识
Language Use and Conventions rewards control. Grammar should be dependable, diction precise, sentences purposeful, and tone appropriate for a formal argument.
深入理解
This domain is about control, not decoration. The essay does not need ornate language. It needs sentences that are accurate, readable, and appropriate for a formal argument.
- What earns points: grammar that stays out of the way, diction that names the real claim, sentence variety used for emphasis, and a tone that sounds measured rather than casual.
- What weakens scores: vague praise, slang, tangled sentences, or technically correct prose that still feels repetitive and imprecise.
- Revision move: after drafting, do one sentence-level pass where you ask three questions: Is this correct? Is this precise? Is this the tone of an argument rather than a conversation? If not, revise before adding new ideas.
