听力原文：Watches, which ore really small clocks, were first made during the sixteenth century. The earliest watches were made of heavy iron, and people wore them hanging from their belts. Little by little, watches were made smaller so that they could be carried more easily. The invention of the machinery for the mass production of these parts of clocks and watches was an important step in making clocks and watches available to the general public. In some watches, small pieces of precious stones, such as rubies or sapphires, are used at the points on which the wheels mm. Since these stones are very hard, they do not wear down very easily under the friction of the moving wheels. Thus a watch utilizing such stones will keep accurate time over a much longer period than other watches.
