The following figure is a schematic cross-sectional view of two rivers in a basin in southern China. Look at the picture and answer the following questions. Question 1: Among the four places, it belongs to the place where "water rush" is easy to occur in Feng Shui.

Question 1:A?

Question 2:B

Test analysis:

Question 1: Reading the map, according to the contour curve, the flow direction of the river is opposite to that of the contour curve, and it can be judged that ① the river flows to the right, and the northern hemisphere is subjected to geostrophic force to the right, A is a concave bank with strong erosion, and A is right. B is a convex bank, which is not easily washed away by water. B is wrong. (2) According to the legend, the terrain on both sides of the river is high, so it is not easy to develop water flushing, and C and D are wrong.

Question 2: Rivers in southern China have no ice age. A is wrong. In summer, the river has a large amount of water and carries a lot of sediment, so ① the sediment radius of the reach is larger than that in winter, and B is wrong for D. The information in the picture can't judge the direction of water flow in the second section, and C is wrong.
