How to Connect Cause and Effect
Sometimes, simply saying "very" isn't enough.
"The food was very spicy." (Okay, but what happened?)
To explain the result of that feeling, we use the So... That... pattern.
The Rule
Subject + Verb + SO + Adjective + THAT + Result Sentence
Step-by-Step Construction
Start with the Cause (using SO): "The car was so expensive..."
Add the Connector: "...that..."
Add the Result: "...I didn't buy it.
Full Sentence: "The car was so expensive that I didn't buy it."
Examples
Cause: The exam was hard. Result: Everyone failed. "The exam was so hard that everyone failed." 📝
Cause: She is funny. Result: Everyone likes her. "She is so funny that everyone likes her." 😂
Common Mistakes to Avoid
Don't use "very" in this structure.
❌ Incorrect: "It was very cold that we stayed home."
✅ Correct: "It was so cold that we stayed home."
Your Turn
Complete this sentence: "I was so hungry that I ate ______."
Did you eat a whole pizza? A horse?
