Step-by-step explanation:
Do you want to know how to identify the main parts of a sentence? Well, you're in luck, because I'm going to show you a simple trick that will make your grammar teacher proud. All you have to do is __under line__ the simple subject once and verb twice in this sentence. What sentence, you ask? How about this one: Dave Kunst took this idea and ran with it about 20 million steps farther. Literally. He walked around the world for four years and three pairs of shoes. Now, let's apply the rule. The simple subject is the person or thing that does the action or is described by the sentence. In this case, it's Dave Kunst, so we underline him once. The verb is the word or words that show the action or state of being of the subject. In this case, it's took and ran, so we underline them twice. And that's it! You've just learned how to find the simple subject and verb in a sentence.
