Update my to-do list (Student’s Book, page 5)
- Water is everywhere.
Surface water covers over 70% of our planet. There is more water underground; we call it “groundwater”.
- Clean fresh water is rare.
→ About 97% of the Earth's water is sea water.
→ $\frac{2}{3}$ of the fresh water is locked up in ice or deep underground. We can reach $\frac{1}{3}$, but most of that is polluted.
→ Only about 0.3% of fresh water is left for us to drink.

答案： over 70%; About 97%; $\frac{2}{3}$; $\frac{1}{3}$; Only about 0.3%
