Material 1: G20 summit in 20 13 was held in St. Petersburg on September 5-6, and G20 summit in 20 12 was held in Mexico on June 8.

Question 1:B

Question 2: D.

Test analysis:

Question 1: Arrow 12③ represents the midday sun ray from the bisector to the sun. Look at the picture, ① the solar altitude angle is the largest, so it is the solstice in summer, ③ the solar altitude angle is the smallest, it is the solstice in winter, and ② it is the vernal equinox. Combined with the summit time of 20 12 and 20 13, it is obvious that these two solar terms should be summer solstice and autumn equinox. So choose B.

Question 2: G20 Summit will be held on September 5-6 in 2013. Meiyu occurs in the middle and lower reaches of the Yangtze River in China, usually from mid-June to early July every year. A mistake. The mistakes in b and c are obvious. During this period, the direct point of the sun is moving southward and getting farther and farther away from Guangdong near the equator, so the days in Guangdong are getting shorter and shorter and the nights are getting longer and longer.
