Review — How to Find the Subject

In English exams, students often choose the most important noun. But the subject is not the “important word” — it is the doer.

2-Step Method

  • 1. Locate the main verb.
  • 2. Ask: who or what does that verb?

Common Traps

  • Objects (receive action)
  • Words inside prepositional phrases (for, in, on, at)
  • Adverbs (how, when, where)
If you cannot answer “who does the verb?”, you have not found the subject yet.
