Traditional folk houses in northern China have the following characteristics: a. The roof slope is relatively large; B. the slope ratio of the roof is small; C. the wall is relatively thin; D. the windows face more. B

Analysis of test questions: The northern part of China has high latitude and low temperature, and the annual precipitation is less than 800 mm, so the roof slope is small and the wall is thick, which plays a role in preventing cold and keeping warm. The direct sunlight is in the tropic of cancer in summer, in the tropic of cancer in winter, and in the equator in spring and autumn, all in the south of the northern region, so the houses in the north face south, and most of the windows face south. The roof slope in item A is steep, which belongs to the characteristics of traditional houses in the south, because there is more precipitation in the south, and the roof slope is beneficial to rainwater. So, the answer to this question is B.

Comments: This question is not difficult. Ask students to combine the characteristics of temperature and precipitation in the northern region, and then get the characteristics of traditional houses in the north, and then get the answer.
