Question 1: b

Question 2: c

Question 3: b

Test analysis:

Question 1: Fuzhou, the capital of Fujian province, belongs to the northern hemisphere, and the annular solar eclipse occurred on May 2 1. Looking at the map, we can see that this day is located between March 2 1 day of the vernal equinox and June 22 of the summer solstice, which is closer to the summer solstice, so we choose B.

Question 2: The date of the annular eclipse is May 2 1. Reading the map, we can see that it is between March 2 1 day of the vernal equinox and June 22 of the summer solstice. During this period, the direct point of the sun moved from the equator to the tropic of cancer, that is, the direct point of the sun was in the northern hemisphere, so the length of day and night in the northern hemisphere was longer, so C was chosen.

Question 3: The earth revolves around the sun at the same time, which is called the revolution of the earth. The revolution direction of the earth is the same as the rotation direction from west to east, and period of revolution has a year. The phenomenon produced by the revolution of the earth is the change of seasons and the change of the sun's altitude angle, so choose B.
