can give us some fruit, too, such as apples, bananas.
Oranges. We can also get wood from the trees. We
use it to make chairs, beds, and houses. In summer,
Sometimes it is very hot,we can sit in the shade under
the trees. Plants can take energy from the sun and
turnit into food. The plants can make air clean and fresh.
They can protect our environment and make it more beautiful. In a word, we can‘t live without plants.
