The twenty-four solar terms are the crystallization of the wisdom of the working people in China, which has a strong guiding significance for agricultural production. The following picture shows the movement process of the direct point of the sun and the main solar terms.

Question 1:C

Question 2:B

Test analysis:

Question 1: Wheat crops begin to grow when the temperature rises, and the seeds begin to be full when it is "full", which appears in late May every year. Because of the basin topography, Chengdu Plain is not suitable for heat dissipation, and the latitude is low, and spring comes early. Before Xiaoman, the seeds are full, and the northeast latitude is high, so spring wheat is planted.

Question 2: From the long summer to the summer solstice, the sun shines directly in the northern hemisphere, and the direct point moves northward, and the sunrise time in Taipei is gradually advanced. During the summer solstice to early autumn, the direct point of the sun moved southward, and the sunrise time in Taipei was gradually delayed.
