I'm not sure I'm sending this the correct way, but here goes.
 
I have two questions:
 
1.  This came up in a class yesterday--when a sentence begins with a
coordinating conjunction, e.g., but, is it still considered a coordinating
conjunction?
 
 
2.  What do you think is the best textbook for an upper division grammar
class for future teachers--considering what they'll actually have to teach
in junior high or high school?
 
Thanks,   Sandie
