知识点 3

Use correct verb tense, aspect, and mood; keep tense consistent when appropriate.

核心知识

Use the verb form that matches the timeline the sentence already gives you.

深入理解

Rule: Tense questions are rarely about memorizing names. They are about sequence. Look for time markers such as "by the time," "before," "already," and "after."

If one action happened before another past action, ACT often wants past perfect. If the sentence stays in one time frame, keep the tense steady instead of shifting for no reason.
