Question 1:C

Question 2:B

Question 3: D.

Question 1: 1 The earth's revolution speed is the fastest in early October. Point C is located in the winter solstice, and the date is 65438+February 22nd, which is closer to 65438+ 10 month. Point D is the vernal equinox, and the date is around March 2 1, which is closer to February 13. So this question chooses option C.

Question 2: Vancouver is west eight District, which is 16 hours later than Beijing time, February/morning of kloc-0/3, Beijing time, February 13-16 hours = 12, Vancouver time. So this question chooses option B.

Question 3: On February 13, the sun went straight to the southern hemisphere and moved northward. In the northern hemisphere, the days are shorter and the nights are longer. The higher the latitude, the shorter the day. Therefore, the daytime in Vancouver is shorter than that in Changzhou, and the daytime in the two places is getting longer. The sun in Changzhou is higher than that in Vancouver at noon. So choose option d in this question.
