e.g. Mike, this is Adams.

In this sentence, Mike and Adams are content words, so they are stressed.
What about 'is'? 'Is' is a verb. Verbs are content words, which are stressed. I know that a verb is stressed in a sentence. Do we have to stress 'is' in e.g.?

John, this cannot be a complete sentence unless you delete the "e.g."

What is the entire context of this phrasing? (Context = the sentences around this)

If you delete the "e.g." --

Mike = noun, person being spoken to
this = pronoun referring to Adams, subject of sentence
is = linking verb
Adams = noun, predicate noun

If you're referring to HOW you would pronounce this, I'll re-write it below, with the stressed syllables in bold.

Mike, this is Adams.

Let me know if this does or doesn't answer your question.

Thank you. Do you mean 'is' is not stressed? How about the follwoing?

1. How are you?
2. Yes, they are.

In the two sentences, I think the verb 'are' is stressed.

Yes, you're right. In those last two sentences, the verb "are" is stressed. But not in the sentence of introduction. The names are the only words stressed in that particular sentence. In fact, "this is" actually sounds like this: "this'z" -- we don't even pronounce the "i" in "is."

In the sentence "Mike, this is Adams," the word "is" is a form of the verb "be." While verbs are typically content words and stressed in a sentence, in this specific case, the word "is" does not need to be stressed.

When saying "e.g. Mike, this is Adams," the abbreviation "e.g." stands for "exempli gratia" in Latin, meaning "for example." Abbreviations are often pronounced differently from the full words they represent. In this case, "e.g." is usually pronounced as two separate letters, "ee" and "gee."

Therefore, when saying the sentence out loud, you can place stress on the names "Mike" and "Adams," but there is no need to stress the word "is" since it is part of the abbreviation "e.g." and is pronounced as a separate entity.
