听力原文: Sign language has become a scientific hot button. Only in the past 20 years have specialists in language study realized that sign languages are unique--a speech of the hands. They offer a new way to probe how the brain generates and understands language, and throw new light on an old scientific controversy: Whether language, complete with grammar, is something that we are born with, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D.C., the world's only liberal arts university for deaf people.
When Bill Stoke went to Gallaudet to teach English, the school enrolled him in a course in signing. He had been taught a sort of gesture code, each movement of the hands representing a word in English, At the time, American Sign Language (ASL) was thought to be no more than a form. of pidgin English. But Stoke believed the "hand talk" his students used looked richer. He wondered: Might deaf people actually have a genuine language? And could that language be unlike any other on earth? Stoke devoted his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture. For decades educators fought his idea that sign languages are natural languages like English, French and Japanese.

The common resource established to solve these conflicts is Urban Planning. Archaeology must take part actively in the elaboration of this planning, and use its abilities positively to prevent archaeological problems and look for an acceptable solution from the point of view of the protection of the Archaeological Patrimony with regard to urban development. Lamentably, archaeology frequently ignores the possibilities of this course of action and does not have the resources necessary to use the urban standard and the planning figures as other methodological instruments (alongside those traditionally used in Archaeology) to solve the archaeological impact of urban development.
Given that the planning figures are the most efficient way of regulating the ground plan and classify and organize the territory, they are also a useful instrument for organizing an action of the urban Archaeological Patrimony, to prevent its destruction, and, even, to give a value to these types of resources. To achieve this it is necessary to characterize, define and outline the spaces with Archaeological Patrimony within the plan. This outlining must extend from the element under protection towards its surroundings, and must seek the conservation of that space, as well as guarantee the control of the agents or activities that may act negatively upon them. The adequate organization of these spaces needs not only to apply the existing ground legislation, but also develop in each particular case (whether a city or a superior organizing community) a defined regulation. This regulation, adapted to the specification of the elements and surroundings to be protected, provides an adequate organization of the spaces that, due to their own historical values and potential social function, thus require it. To achieve this it will be necessary to not only limit their use, but also to establish solutions for their management and, even, for their socio-cultural use.
This study is illustrated with examples and experiences derived from Galician cities, each of which presents a particular problem: Santiago de Compostela (a mediaeval city, now Patrimony of Humanity) , Lugo (built on the remains of the most important Roman city of Galicia) , and Corona and Vigo (cities with roman-mediaeval antecedents and recent development which today have a very strong urban dynamic). However, instead of carrying out a mere case study based on particular examples, an effort is made to evaluate the Spanish context to help to contribute to making a general diagnosis of the problem and to define the basic conditions that from the author's point of view should comply with the previously mentioned specific regulations.
