simple sentence, also called an independent clause, contains a subject and a verb, and it expresses a complete thought.

Melt!
Ice melts.
The ice melts quickly.
The ice on the river melts quickly under the warm March sun.
Lying exposed without its blanket of snow, the ice on the river melts quickly under the warm March sun.
