Assignment 9

Up to now we have three categories of Auxiliary verb:

Category M:
	will	would
	can	could
	shall	should
	may	might
	must

Category H:
	have1

Category B:
	be1

Which we have incorporated into the VP rule:

	VP -> {M}(H)(B) V ...
	      {T}

Make sure you understand the grammar as it stands, including how the order
of Auxen is determined, and how each verb gets its form.

1.  There is a fourth category of Auxiliary verb:

Category D:
	do1

You'll need to make up your own sentences containing the Aux 'do'.  Be aware
that there is a main V 'do' (we'll call it do0).  Don't confuse it with the Aux
'do' (which we'll call do1).  Also, for this part of the exercise, don't try to
include any negative sentences (like this one), or any contractions (like this one),
or any questions (like "Do you want a whole lot of trouble?").

2.  Under our current theory of auxiliaries, how would you incorporate the Aux 'do'?
Revise the grammar to include Category D in the right place.

Do we need any new form rules?

3.  Now re-do the assignment, taking negated sentences into account.

NOTE:  This is a VERY hard assignment.  Maybe not even possible.  But do your best.
