3 Homework 6 review g21.pl: summary of the changes so far.. 1.A book is/*are available 2.Several books *is/are available 3.A book seems/*seem to be available 4.Several books *seems/seem to be available 5.There seems/*seem to be a book available 6.There *seems/seem to be several books available

4 g21.pl S rules:

5 g21.pl Adjectival Phrase rules:

6 g21.pl VP rules:

7 g21.pl Verb lexicon: 3 different classes of verbs

8 Homework 6: Part 2 Part 2: Wh-questions Modify g20.pl to handle these sentences: 1.Who did John see? 2.*Who John see/saw? 3.Who saw John? 4.*Who did see John?

9 Homework 6: Part 2 One wrinkle … – Linguistic theory: in the object wh-question, there is displacement (i.e. movement) of the underlying object. – For the case of the object wh-question, modify your parse to insert a copy of the fronted wh-phrase in the underlying position – Example: sbarq(whnp(wp(who)), sq(vbd(did), np(nnp(john)), vp(vb(see), whnp(wp(who)))))

10 Homework 6: Part 3 Part 3: extra credit: – Extend your solution to handle the that-trace effect: 1.Who do you think that John saw? 2.Who do you think John saw? 3.Who do you think saw John? 4.*Who do you think that saw John? – modify your parse to insert a copy of the fronted wh-phrase in the underlying position (embedded clause subject or object)
