We oftten speak of language as a vehicle of expression ------a metaphor that can illumine many aspects of our foreign language teaching situation.Language is a vehicle of meaning that we do not even realize we are using; in other words,a vehicle that is transporting a person's message somewhere but is not itself the object of the trip.Before students can use such a vehicle for their purposes,it must be constructed,and this construnction requires a blueprint and various stages of production,with tryouts as the various sections and combinations are assembled-tryouts during which what has been assembled to date is used,if only momentarily,for its ultimate purpose .
