Even the lights at the Sydney Opera House were out for an hour.This saved a lot of electricity.The same amount of electricity could power thousands of computers or television sets for an hour. When the lights were out, the stars were clearer in the sky.

(1) Do you think Earth Hour is useful Why or why not
(2) Have you ever taken part in Earth Hour events before
If yes, describe what you did.
If not, would you like to take part next March
What do you think you will do
Tips：（1）Possible Answers:
Yes, because it raises awareness about climate change and shows how small actions (like turning off lights) can inspire bigger changes.
Yes, but it's not enough alone. We need daily habits (e.g., using renewable energy) to truly protect the Earth.
No, because one hour doesn't save much energy. Instead, people should focus on long-term solutions like solar power.
Tips：（2）Possible Answers:
If YES:
"Last year, my family turned off all lights and used candles. We played board games and talked about how to save energy every day."
If NOT:
"Next March, I'll join by switching off lights and organizing a stargazing event with friends. I'll also remind my school to participate!"

Tips：
How to Calculate Savings:
Check your electricity bill: Find the average hourly usage (e.g., 1 kWh per hour).
Multiply by participants: If 100 families join, that's ~100 kWh saved!
Compare: "This could power a school for X hours or charge Y smartphones!"
Why It Matters:
For Earth: Less CO emissions → slows global warming.
For Us: Teaches mindfulness about energy waste.
