Author Purpose, Perspective, and Structure
These questions ask why the author made a move, who is speaking, and what job each part of the passage is doing.
核心知识
Read for function, not just content. A purpose, perspective, or structure answer is right only if it matches what the passage is trying to accomplish in that exact spot.
深入理解
Start with the job of the passage. Ask whether the writer is trying to explain, argue, narrate, compare, critique, or qualify a claim.
Then track the local move:
- Speaker: whose voice or viewpoint is active here?
- Purpose: what is that voice trying to do?
- Function: does this paragraph introduce, concede, shift to evidence, or judge between ideas?
This skill can appear in literary narrative, humanities, social science, or natural science passages. Do not treat it as literary-only analysis. ACT can ask the same purpose, perspective, or function question in an informational passage, a paired set, or a passage with visual support.
