Solve the following python programming problem given the following code:
def match_transform(self, e) : 
    '
        Check to see if the event e follows one of the verb transformation patterns
        specified at the bottom of the Verb Dictionary file.
        
        If the transformation is present, adjust the event accordingly. 
        If no transformation is present, check if the event is of the form:
        
                    a (b.Q) P, where Q is not a top-level verb. 
           
            and then convert this to (a b P+Q)
        
        Otherwise, return the event as-is.
        
        Parameters
        -----------
        e: tuple
           Event to be transformed
        
        Returns
        -------
        t: list of tuples
           List of modified events, since multiple events can come from one single event
