offered by the relation of thematic relations to syntactic roles as mediated
by the macroroles actor and undergoer in RRG. In mapping thematic rela
tions onto macroroles, there is a markedness hierarchy ("Synopsis", section
3.3.2): for example, agent is the least marked choice for actor, patient the
least marked choice for undergoer, and locative less marked for actorhood
than theme. In Mandarin, where actor and undergoer typically correspond
to subject and object respectively (see LaPolla 1990 for detailed discus
sion), a listener trying to make sense of a CC like (48b) or (49b) must
decide on the basis of the case role required by the V 2 whether it is the actor
or undergoer that is the argument of V 2. For example, V 2 in (48b) is a sta
tive verb, its lone argument should be a patient. Since patient is the least
marked choice for undergoer, the natural interpretation is that the argu
ment which is the undergoer of the entire construction, "shoes", is the argu
ment of "bad". This is represented in Figure 1. Encoding proceeds upward
from logical structure to the layered structure of the clause, and interpreta
tion goes downwards from the clause to logical structure. In terms of
interpretation, (3) to (2) is no problem, the subject is the actor and the
object is the undergoer. Relating (2) to (1) is no problem for Vl5 since with
"chew" effector corresponds to actor and locative corresponds to under
goer. The macrorole status of the argument of V 2 is problematic however,
especially since both shoes and dogs can be "bad" (not to mention the fact
that dogs that chew up shoes are especially bad!). However, since the inher
ent lexical properties of "bad" require the thematic relation patient for its
argument, and since the macrorole undergoer is the least marked choice for
