Case Filter and Case Theorem come into play to account for the distribution of lexical NPs and PRO. Chomsky (1980) argues that PRO must be ungoverned since it is regarded as both an anaphor and a pronominal simultaneously. By definition, Case should be assigned under government. It explicitly implies that lexical NPs and PRO are mutually exclusive with each other. That is, lexical NPs are allowed to appear where PRO is prohibited. This paper presents "unusual" patterns of PRO. On the empirical side, the distribution of PRO is by far wider than predicted from the theoretical basis. The "unusual" cases exhibit that PRO can occur in the finite clause with both anaphoric and dependent tense. Control does not need to be restricted to infinitival complement clauses. It can readily expand into finite complement clauses. Interclausal dependency via control may be established between the matrix clause and the complement clause including infinitival and finite clauses as well.
