----------------------------------------------------------
Are #2 and #3 the negative sentences of #1?
Does #3 mean #4? Does #2 mean #4?
Does #3 mean #5? Does #2 mean #5?
What is the exact meaning of #2 or #3 in negative sentences?

Answer 1

I wouldn't use #3, but #1 and #2 are opposites (or negatives) of each other.

#3 is not used, and #4 is VERY wordy. Since it's a "sometimes" idea, all you need is one half of that sentence or the other, but not both. Also, the word "sometimes" needs to be at the beginning of the sentence, not between the subject and verb.

#5 is well phrased. This is a really good opposite for #1.

Answer 2

#5 is correct
