120 ROBERT D. VAN VALIN, JR.
Adverbial subordinate clauses are not introduced by complementizers
in English but rather by predicative prepositions which have clausal argu
ments (see FVV:93). This is exemplified in (110) and Figure 36.
(110) a. John saw Mary after he arrived at the party.
b. [after' ([BECOME be-at' {he, the party)], [see' {John,
Mary)])
