The Game-Changing Two-Change Rule
🎯 The Secret: Every Part 4 transformation involves exactly two changes from the original sentence. Master this rule, and you'll never overcomplicate transformations again.
This "two-change rule" means you should:
- Identify the first change (usually grammatical structure)
- Identify the second change (often lexical or register)
- Stop there – don't overcomplicate
| Change Type | What It Involves | Examples |
|---|---|---|
| Grammatical | Structure transformation | Active → Passive, Direct → Reported speech |
| Lexical | Word substitution | Formal → Informal, Synonyms |
| Register | Formality level change | Phrasal verbs ↔ Formal verbs |
Two-Change Rule in Action:
Original: "I'm certain Tom didn't take my book," said Mary.
Key word: DENIED
Complete: Mary ______________ her book.
Analysis:
- Change 1: Direct speech → Reported speech structure
- Change 2: "I'm certain...didn't" → "denied" (lexical change)
Answer: Mary denied that Tom had taken her book.
(5 words including 'denied')
