Exercise 3 The exercise asks for the tree structures for the following sentences. I have included disambiguating clauses in parentheses where needed to indicate the interpretations I am assuming. Other readings are often possible for these sentences.
18. get sentences:
a. John got arrested.
b. John got Mary arrested (to satisfy his need for revenge).
c. John got the bicycle stolen from him (when he wasn't paying attention).
19. have sentences:
a. Mary had John arrested (to satisfy her need for revenge).
b. Mary had John steal the bicycle (on her when she wasn't paying attention).
Here are the intended structures:
According to the grammar tool "have-get," the variants of the two verbs require the following subject thematic roles:
get-1 - experiencer
get-2 - agent
get-3 - none
have-1 - agent
have-2 - experiencer
From this array of roles, we can deduce that get-3 does not license accusative case. Therefore, when it takes a passive verb in its complement, the object of the passive must move all the way up to matrix subject position to be case-licensed. This derivation is illustrated in (18a). The other two variants of get have subject thematic roles and so can license case on their complements or to the specifier of their complements without violating Burzio's generalization. In fact, they do and differ only in which role they assign to their subject position. All forms of get subcategorize for a passive participle and do not accept a bare infinitive. As result the direct object of the lower verb (arrested or stolen) always moves to a subject position.
In actual English, get also subcategorizes for a to infinitive and in this subcategorization the direct object remains in place, as in:
I got Mary to steal the bicycle.
Main verb have licenses both a bare infinitive and a passive participle. It always assigns a thematic role to its subject so Burzio's generalization allows it to assign case to a complement or specifier position on its right. It always does so except when it is used with the meaning of a modal, as in:
John has to return the bicycle.
The thematic role of the subject of have may be either agent or experiencer. What happens to the direct object of the lower verb depends on the verb's form in the expected way.
