Read the schematic diagram of a river reach in a southeast area and answer the questions. Question 1: Among the four navigation channels in this reach, the ones that are favorable for navigation are: A.

Question 1:C

Question 2:C

Test analysis:

Problem 1: The concave bank of the curved reach of the river is seriously eroded, while the right bank of the northern hemisphere of the straight reach is seriously eroded, and the riverbank is deeply eroded, which is beneficial to navigation.

Question 2: The terrain at C is flat, close to the river, and it is convenient to take water, which is suitable for construction of the village.

Comments: Combined with the channel characteristics of rivers, it is not difficult to investigate the influence of geostrophic deflection on rivers.
