Question 1:D?

Question 2:B

Test analysis:

Question 1: The change of the terminal line and the tangent point of latitude reflects the position of the sun's direct point, and the latitude of the latitude tangent to the terminal line is complementary to the latitude of the sun's direct point, so ① indicates that the second solar term from the second to the future is severe cold or hot summer, ② indicates that the third solar term after the second vernal equinox is long summer or beginning of winter; (3) means two days; (4) refers to the solar terms or two to three days before heavy snow.

Question 2: When the tangent point is from ① to ②, the Arctic is extremely day to night, and the direct point moves to the south, so the rotation angle of the earth's sun shadow in Jianghuai becomes smaller; From the tangent point ① to ②, the solar term is from summer to beginning of winter, and the late rice in Wanjiang Plain is from transplanting to harvesting. Herbivores on the African savanna migrate southward; The monsoon circulation in the North Indian Ocean is clockwise first and then counterclockwise. So b is correct.
