The subject
Please can you make your question clearer. Are you talking about a sentence that starts with the word 'Are'? Or are you talking about a sentence that starts with the words 'Are it'? If you are talking about a sentence that starts with the word 'Are', such a sentence must be a question. If you are talking about a sentence that starts with the words 'Are it', such a sentence is ungrammatical. When you have made that clear, please also make it clear exactly what your question is with respect to the sentence. Then someone will be happy to help you. Thank you.
no, it's a sentence fragment.
No, not if that is the whole sentence. "I was talking to you" is correct as a sentence. It is also correct to use "I were talking to you" as part of a sentence: "If I were talking to you, I would probably say something that I would regret."
The gerund phrase in the sentence is "talking to my friend Omaha."
No. The pronoun 'we' includes 'I/myself' so 'we' cannot be talking to 'myself'. These sentences are correct I am talking to myself. We are talking to ourselves.
Death!Unless your talking about a prison sentence.
This is a complex sentence. It consists of an independent clause "I was talking on the phone" and a dependent clause "while I was talking on the phone to Walter."
The objective
what are you talking about
The subject is the one that tells who is the sentence talking about, respectively.
its a sentence that is about the story but it makes good sense about what your talking about
The gerund phrase in the sentence is "talking to my friend." It is functioning as the object of the preposition "for."
