Question 1:B

Question 2: A.

Test analysis:

Question 1: As can be seen from the temperature curve, the temperature in this period is between 8℃ and 16℃, which is only available in spring and autumn in the middle latitude of the northern hemisphere. Judging from the temperature change (especially the daily average temperature), it should be increased, and the radiation time of the sun in one day has increased. So it's in spring.

Question 2: The quality of agricultural products is closely related to the effective accumulation of organic matter. In order to accumulate more organic matter, it is necessary to have a large temperature difference between day and night, a high temperature during the day, strong solar radiation conducive to photosynthesis and organic matter synthesis, and a low temperature at night, which weakens respiration and reduces organic matter consumption.

Comments: This topic examines the weather characteristics and its influence on agriculture with the background of reading pictures. The key to solve the problem is to look at the picture and analyze the changing law of solar radiation, which meets the requirements of the college entrance examination.
