Seventeenth-century houses in colonial North American were simple structures that were primarily functional, carrying over traditional designs that went back to the Middle Ages.  During the first half of the eighteen century, however, houses began to show a new elegance.  As wealth increased, more and more colonist built fine houses. Since architecture was not yet a specialized profession in the colonies, the design of buildings was left either to amateur (业余) designers or to carpenters who were engaged in translating architectural handbooks imported from England.  Inventories of libraries shows an astonishing number of these handbooks for builders, and the houses built during the eighteenth century show their influence.  Nevertheless, most household architecture of the first-quarters of the eighteenth century displays a wide divergence of taste and freedom of application of the rules laid down in these books. Increasing wealth and growing sophistication (文化修养) throughout the colonies resulted in houses of improved design, whether the material was wood, stone, or brick.  New England still favored wood, though brick houses became common in Boston and other towns, where the danger of fire gave an impetus (推动) to the use of more durable material.  A few houses in New England were built of stone, but only in Pennsylvania and areas nearby was stone widely used in buildings.  An increased use of brick in houses and outbuildings is noticeable in Virginia and Maryland, but wood remained the most popular material even in houses built by wealthy landowners.  In the Carolinas, even in closely packed Charleston, wooden houses were much common than brick houses. Eighteenth-century houses showed great interior improvements over the former ones.  Windows were made larger and shutters removed.  Large, clear panes replaced the small leaded glass of the seventeenth century.  Doorways were larger and more decorative. Fireplaces became decorative features of rooms.  Walls were made of plaster or wood.  White paint began to take the place of blues, yellows, greens, and lead colors, which had been popular for walls in the earlier years.  After about 1730, advertisements for wallpaper styles in scenic patterns began to appear in colonial newspapers. 小题1:What’s the passage mainly about?
