HI!!I came across those two sentences in a test in this site..
1)Never have I seen such a mess
2)Sometimes I have seen such a mess.
My questions are:
a)I understand that the first is correct (inversion-wise) but shouldn't there be a ''never before'' instead of just ''never''?
b)Can ''sometimes'' be used in present perfect?I'm not sure about it but it seems totally inappropriate used that way here.Looking forward to an answer.
