Exercise 2 Draw trees

Using only the syntactic categories listed above,

a. draw plausible phrase structure trees for the odd-numbered sentences. Assume that the bracketed expressions are VPs.

Draw the trees with the program at the following website:

jsSyntaxTree

Example: to draw a tree for sentence (12) above, paste the following line into the textfield of jsSyntaxTree:

• [S [NP [N We]] [VP [V gave] [NP [N Fred]] [NP [D a] [N wastebasket]]]]

Download each tree by clicking on it.

b. Write the phrase structure rules needed to license the trees you drew.
