Question

Identify the subject and verb in this sentence i gazed at the mountain

Answer 1

The verb of the sentence is "gazed", the subject of the sentence is the mountain.

Answer 2

Actually, I is the subject. Gazed is the verb. At the mountain would be your prepositional phrase, with mountain being the object of the preposition. At the mountain is also your predicate as it occurs right after the verb gazed.
