as a subject
The subject of the sentence is who or what the sentence is about. Most of the time in simple sentences like this one, the subject is at the beginning of the sentence. A gerund is a verb that acts like a noun and ends in -ing.
Direct objects receive the action of the verb. This sentence does not have an action verb so it does not have a direct object. The indirect object receives the direct object. For example. I gave Jack the ball. Ball is the direct object because it receives the action "gave". I also think about it in terms of what do I touch first if I'm going to do the action. Then the indirect object is Jack because he receives the ball. He is where I'd go to second. An appositive is a noun that renames or describes another noun. It is usually set off by commas. For example, Jack, my brother, took the ball. My brother is the appositive because it is renaming or describing who Jack is.
