explain the differences in these sentences:
+/ She will have finished her work by 7pm
+/ She will have finished her work before 7pm
+/ She will have finished her work at 7pm

+/ She will have finished her work by 7pm
+/ She will have finished her work before 7pm
Not much difference betwqeen these two- 7 is the limit. The second sounds as if she will have finished the work comfortably bbefore the limit, while the first could go up to the last minute.

+/ She will have finished her work at 7pm

This could be making an assumption now about an action that has finished- I know her timtetable and it's 7-15, so I can say this in answer to a question about her whereabouts.
:D

But is "She will have finished her work at 7pm" a sentence likely to be heard in actual use? It doesn't seem very probable to me.

Not really, but you might say 'She'll have finished her work at 7, so she'll be on her way home now.' Other than that, it's not very probable. ;-)
