1. It's very noisy here. I can't stand it any more.
(What does "it" refer to in the first sentence? What does "it" refer to in the second sentence? Are both the same? Is 'it' an impersonal pronoun or just a pronoun which refers to something that is mentioned before?)
In the first sentence, "it" is an impersonal pronoun that doesn't have an antecedent. In the second sentence, "it" seems to refer to the noisiness.
