Question

1)How do you choose the verbal form between "have been V-ing" and "have V-ed" with "for" or "since". Whats the difference between "I have been living in Atlanta for ..." and "I have lived in Atlanta for ...." ?
2) Chocolate is the same in the singular and plural? Are there another words like that?
3) What is the difference bettwen "to make a note of something" and "to take a note"

Answer 1

'Have been living' indicates that the person has lived and is still living in that place for the no. of years mentioned. 'Have lived' to me would create a doubt whether the person is still living in that place, though he had lived there earlier - he might still be living there when he made the statement, but it is not certain. For example, if one says 'I have lived in Atlanta for 10 years to know all the bus routes by heart' lays emphasis on the duration spent in Atlanta in relation to the knowledge gained about bus routes, but it need not necessarily mean that he continues to live there. At least this is my interpretation!
Chocolate is a generic indicating something made from cocoa beans, whether it be in drink form or candy form. Its plural would be chocolates, such as 'There are two types of chocolates: white and dark brown in color.'
To make a note and to take a note are used interchangeably. The addition of 'a' in 'to take a note' might show that it is a sort of written note that is taken, but I am not sure if this is correct.

Answer 2

I have been living in Atlanta for......., and I have lived in Atlanta for....., basically say the same thing. Ed is added to make the past tense, I have been...ing makes a past participle.
More than one chocolate is chocolates
Making a note can be just remembering something or writing it down. Taking a note is literally writing something that helps one remember something.

Answer 3

Deer and moose are the same plural and singular.
