The picture shows "the curve of sunrise time in a year in A, B and C regions of China", in which A, B, C, D and E are solar terms. Look at the picture and answer the questions.

Question 1:C

Question 2: D.

This question examines the length of day and night.

Question 1: China is located in the northern hemisphere, where the sunrise is the earliest in summer solstice and the latest in winter solstice, so solar term B is winter solstice and summer solstice D is summer solstice, from which it is deduced that A is autumnal equinox, C is vernal equinox and E is autumnal equinox. From summer to the sun, the higher the latitude in China, the earlier the sunrise, that is, the farther north the sunrise, the northernmost A and the southernmost C, so choose item C.

Question 2: in solar terms a ~ e, a and e are the same; Therefore, item A is wrong. In a year, the direct point is located in the northern hemisphere for half a year, the earliest time to see the sun is early winter for half a year, and the sun is the latest; Therefore, item C is wrong. C is the vernal equinox, and the local sun rises at 6 o'clock at C. At this time, Beijing time is about 6 o'clock 16 minutes, and the difference between the local and east longitude 120 degrees is about 4 degrees, and the longitude is about east longitude16 degrees, and it is still located in East Zone 8. Therefore, item D is wrong. So choose item B.
