+
+Don't forget to include examples of topicalization.
+They look like this:

+\enumsentence{Topicalization from sentential subject:\\ 
+\shortex{7}{a John$_i$ [a & kltukl & [el & 
+  {\bf l-}oltoir & er & ngii$_i$ & a Mary]]}

+  {\bf IR}.{\sc 3s}-love   & P & him & }
+{John, (it's) clear that Mary loves (him).}}
+}
+
+\subsection*{How to handle topicalization}
+
+I'll just assume a tree structure like (\ex{1}).
+
+{\small

+
+\subsection*{Mood}
+
+Mood changes when there is a topic, as well as when
+there is WH-movement.  \emph{Irrealis} is the mood when
+there is a non-subject topic or WH-phrase in Comp.
+\emph{Realis} is the mood when there is a subject topic
