The chart below shows the daily variation of solar radiation reaching the ground in a certain place in China. Look at the picture and answer the following questions. Question 1: What is the date and weather of the day?

Question 1:D?

Question 2:C

Test analysis:

Question 1: The date can only be judged by the length of a day in the picture. During the day, the sun rises with solar radiation, but at night, it doesn't. It can be seen that the sun rises at 4 o'clock and sets at 19, and a day is 15 hours, which is shorter than 12, indicating that the day is long and the night is short, which is the summer half year, that is, March 26552. The height of the sun is the highest at noon. Only considering this factor, the maximum solar radiation should be around 1 1:30, but it is the second last in the figure, indicating that the solar radiation is weakened, which should be weakened by clouds, that is, cloudy. B is wrong and D is right.

Question 2: First of all, at noon (local time here is 12) and Beijing time is 1 1:30, we can see that the longitude difference here is 7.5, that is, 127.5, so only C answered.
