CONCLUSION
</SectionTitle>
    <Paragraph position="0"> There are some idioms which exist only in the passive form, or in the question form, and the correspond;no trees are directly selected. In French, &amp;quot;~tre pris par le temps&amp;quot; (to be very busy) lacks its active counterpart (* Le temps prend Jean), and &amp;quot;Quelle mouche a piqe6 NP ?&amp;quot; (What's eating NP ?) lacks its non interrogative 13 &amp;quot;l'he derived trees are the same (modulo the syntactic features explained above).</Paragraph>
    <Paragraph position="1">  It has been shown that taklno, idiomatic or semi-idiomatic constructions into account in a French or Enali~ grammar forces one to define some lexical constraints on syntactic rules such as whquestion, pronominaliTation and topicalization. Such a lexical treatment has been exemplified using Lexicalized Tree Adjoining grammars. An interestlno point about TAGs is that, due to their extended domain of locality, they enable one to consider as 'lexicar syntactic rules bearing on constituent structures, and not only rules changing the syntactic category of a predicate (as D. Dowry 1978) or rules chan#,~ the argument structure of a predicate (as in T. Wasow 1977 or D. Flickinger 1987).</Paragraph>
