    Last year the empty land across from my bus stop was a sad, empty, ugly space, with dead bushes and one short tree. Then some1. (gardener) changed that. They were tired of looking at the sad space while they were waiting2.the bus, so they made it into a beautiful garden. Now you can see colorful vegetable plants and sweet-smelling flowers. Yellow butterflies fly from plant to plant3. (happy), and tiny birds sing in the green trees. I love taking the bus now.
