Countable and uncountable nouns
In English, we can count some things, e.g. rivers and mountains. We cannot count other things, e.g. water and air.
Countable nouns Uncountable nouns
one animal, two animals some rubbish
I have a world map at home. There is an article about the Earth. All plants need light and water.
This plant is beautiful. These animals are dangerous. Air has no smell.
