🔥 Exam Tip & The Advanced Transformation Cheat Sheet:
- Formula 1 (Contrast):
👉 Simple: In spite of / Despite + (Verb+ing / Noun)
👉 Compound: Subject + Verb, but / yet + ...
👉 Complex: Though / Although / Even though + Subject + Verb...- Formula 2 (Reason):
👉 Simple: Being / On account of / Due to ...
👉 Compound: Subject + Verb, and so / therefore + ...
👉 Complex: As / Since / Because + Subject + Verb...- Formula 3 (Result):
👉 Simple: too ... to (too weak to walk)
👉 Compound: very ... and so (very weak and so he cannot walk)
👉 Complex: so ... that ... cannot (so weak that he cannot walk)- Golden Rule: A Simple sentence has ONE main verb. A Compound sentence joins two independent sentences with FANBOYS (for, and, nor, but, or, yet, so). A Complex sentence uses binders like When, If, Though, As.
