12 Translate into English without a dictionary: Крыша дома состоит из следующих элементов (см. Figure 9.3.): наклонных плоскостей, называемых скатами (1), основой которых служат стропила (2) и обрешетка (3). Нижние концы стропильных ног опираются на мауэрлат (4). Пересечение скатов образует наклонные (12) и горизонтальные ребра. Горизонтальные ребра называют коньком (5). Пересечение скатов, образующие входящие углы, создают ендовы и разжелобки (6). Края кровли над стенами здания называют карнизными свесами (7) (располагаются горизонтально, выступают за контур наружных стен) или фронтонными свесами (11) (располагаются наклонно). Вода по скатам стекает к настенным желобам (8) и отводится через водоприемные воронки (9) в водосточные трубы (10) и далее в ливневую канализацию.
