"The class" is the indirect object. In English, the indirect object is usually something that could also be expressed by putting "to" in front of it. The sentence could be rephrased "The teacher told a story to the class."
First, this is an imperative sentence-- it gives a command. The subject of the sentence refers to the person or persons being told to perform the action-- "class" (in other words, the command is being given to the members of the class). The predicate means the verb-- the action word. So, what is the speaker (probably the teacher) asking the class to do? The action word here is "read." The class is being asked to "read" something, and that is the simple predicate.
The word "his" is a possessive adjective, a pronoun placed before a noun to describe that noun (story) as belonging to a male.The word "he" is a subject pronoun, and "him" is an object pronoun.
You say "He laughed." Trying to use fancy terms instead of just saying "he said," or "she laughed," or "he coughed" just ends up being confusing and the reader loses interest in your story.
